"Thatrotter of a garage fellow!" exclaimed Athol Hawke explosively. "He hasn't done a thing to the wheel; and, what is more, he rushed me sixpence for garaging the bike, the young swindler."

"Didn't you go for him?" enquired his chum, Dick Tracey.

"He wasn't there to go for," replied Athol. "He was away on some job, and left the explanations to a youngster. But, my word, it is snowing! Think she'll stick it with that groggy wheel?"

The scene was the Market Square, Shrewsbury. The time, nine o'clock on a Saturday morning, March, 1916. It was, as Athol remarked, snowing. A week or more of intermittent blizzards had culminated in a steady fall of large, crisp flakes, and judging by the direction of the wind, the heavy, dull-grey clouds and an erratic barometer, the worst was yet to come.

Athol Hawke was a lad of seventeen, although he looked several years older. He was tall, lightly yet firmly built, of bronzed complexion, grey eyes and with dark hair. The fact that he was wearing waterproof overalls, leggings and fur gloves tended to conceal his build.

His companion, who was similarly attired, was Athol's junior by the short space of three days. In height he was five feet seven—four inches less than that of his chum; build, thick-set; complexion might have been fair but exposure to wintry conditions had resulted in his face being burnt to a reddish colour. His hair was light brown, with a tendency to crispness; his eyes blue. By disposition he was remarkably bright and cheerful, characteristics that served as a foil to Hawke's almost invariable staidness.

The two chums were riding a motor-bicycle and side-car. They had "been on the road" nearly a week. What possessed them to select a time of blizzard and equinoctial gales to go tearing across England; why they were apparently "joy-riding" in wartime; why they chose a district that was most decidedly within the region of activity of hostile air-craft—all this will have to be explained in due course.

At eleven o'clock on the previous day they had ridden into the quaint and picturesque old town of Shrewsbury, having left Chester shortly after daybreak. During the run they had made the disconcerting discovery that several of the spokes of the side-car wheel had worked loose, possibly owing to the drag of the snow and the atrocious "pot-holes" and setts of Lancashire. The wheel might last out till the end of their tour—and it might not. Dick suggested risking it, but the ever-cautious Athol demurred. They would remain at Shrewsbury, he declared, until the following day and get the damage made good.

A motor mechanic had promised faithfully to carry out the job, and had let them down badly.

"Well, what's the programme?" asked Athol. "We may be able to push on, but I guess it's pretty thick over the hills. Already there's a good two inches of snow—and it's still tumbling down."

Dick surveyed his surroundings in his customary optimistic manner. The cobbled square was already hidden by a dazzling white mantle. The roofs of the old buildings and the detached pillared market-house were covered with fallen flakes. A weather-worn statue, poised stolidly upon a lofty pedestal, was fast resembling the time-honoured character of Father Christmas.

Save for a few belated lady-clerks of the Army Pay Department, who cast curious glances at the two snow-flaked motor-cyclists as they hastened to their daily toil, the square was deserted. At the corner of an adjacent street two recruiting sergeants stood in meditative silence, regarding with a set purpose the pair of strapping youths.

"More of 'em, by Jove!" exclaimed Dick, as his eyes caught those of one of the representatives of His Majesty's Army. "Here they come, old man. Stand by to give 'em five rounds rapid."

"Nothin' doing, sergeant," announced Athol as the foremost non-com., beaming affably, vouchsafed some remark about the weather as a preliminary feeler to a more important topic. His companion had diplomatically "frozen on" to Dick.

With a dexterity acquired by much practice each lad unbuttoned his mackintosh coat and from the inner breast pocket of his coat produced a formidable-looking document.

"Bless my soul!" ejaculated the first sergeant. "Who'd a' thought it? Very good, sir; we can't touch you—at least, not yet. You never know."

"You speak words of wisdom, sergeant," rejoined Athol, as he replaced his paper. "Now, to get back to more immediate surroundings, what do you think of our chances of getting to Ludlow to-day?"

"On that thing?" asked the sergeant. "Not much. It's as thick as can be over Wenlock Edge. This is nothing to what's it's like up there. You'd never get through."

The word "never" put Dick on his mettle.

"We'll have a jolly good shot at it, anyway," he said. "Come along, Athol, old man.Hop in and we'llhave a shot at this Excelsior business."

Athol Hawke would like to have lodged a protest. He was anxious concerning the groggy side-car wheel, but almost before he knew where he was, Dick Tracey had started the engine and the motor was swishing through the crisp, powdery snow.

Down the steep Wyle Cop and across the narrow English Bridge they went, then turning shook the snow of Shrewsbury from the wheels, since it was literally impossible to shake the dust from their feet.

Mile after mile they reeled off, the road rising steadily the while. Tearing through the snow flakes was really exhilarating. The air was keen and bracing; the scenery fairy-like in the garb of glittering white.

"Glad we pushed on," exclaimed Dick. "We're doing it on our heads, don't you know. The little beast of an engine is pulling splendidly."

The words were hardly out of his mouth when there was a perceptible slowing down of the three-wheeled vehicle, although the motor throbbed with increasing rapidity.

"Belt slipping," declared Athol laconically.

"It's the leather one," said his companion as he stopped the engine and dismounted.

"We'll shove the rubber one on. Leather always is rotten stuff to slip in the wet, and yet there's a proverb, 'There's nothing like leather.'"

"Doubt whether the other one will do any better," remarked Hawke. "See, the lowermost part of the belt rim has been ploughing through the snow. This is the thickest we've had so far."

"It is," assented Dick. "But we'll push on. It is a pity to turn back. We can't be so very far from Church Stretton now. From there it's downhill almost all the rest of the way."

The change of belts was effected and the journey resumed. For the next quarter of a mile progress was good, although great care had to be exercised to avoid the snow-banks on either side of the road.

Presently the road dipped with considerable steepness, and bending to the right crossed a small bridge. Beyond, it again rose and with increased gradient, and appeared to plunge directly between two lofty hills. The rising ground was thickly covered with pine trees, each branch bending under the weight of virgin snow.

"Looks like a bit of Switzerland," observed Dick. "Hanged if I can see why people want to go abroad to see scenery when there are places like this at home. But, my word, we've a stiff bit of road to tackle! Wonder if she'll do it?"

"She's got to," said Athol grimly. He was one of those fellows who embark upon an undertaking with evident misgivings, but when fairly in the thick of it warm to their task and are undaunted in spite of difficulties and rebuffs.

But there are limitations even to the capabilities of a three and a half horse power motor. Right nobly the engine did its work, but once again the belt slipped with exasperating loss of power. So deep was the snow at this point that the lower framework of the side-car was ploughing through it, while the heated crank case coming in direct contact with the snow was throwing off vapour like a high pressure steam engine. To add to the difficulty an accumulation of compressed snow had choked the front mudguard.

"All alight here!" shouted Dick. "By Jove, we'll have to jolly well push up this hill."

With the engine still running on low gear the lads literally put their shoulders to the wheel. It was hard work. In spite of the lowness of the temperature they were glowing with exertion, as, under their united efforts, they advanced at the rate of a mile an hour.

"Jolly long way to the top," panted Dick. "Hope we don't get snowed up. I say, that looks cheerful."

He pointed to a derelict motor car, almost hidden in a drift by the side of the road, where the bank of snow had risen to at least seven feet in height.

"Can't be much farther to Church Stretton," said Athol encouragingly. "Buck up, old man."

For another fifty feet they struggled manfully, until Tracey switched off the motor and brought the bike to a standstill.

"Spell-oh!" he announced, shaking the powdered snow from his cap. "I've had enough for a bit."

"If we stop we—like the drunken man—'goes over,'" declared Athol. "Every minute things are getting worse."

"Can't help it," rejoined Dick breathlessly. "Like the engine, I'm badly overheated."

For some moments the two chums stood still, taking in as much of the scenery as the snowstorm permitted, for so thick was the air with falling flakes that they could form no idea of the height of the hills on either hand.

Presently a horseman appeared, his mount floundering through the snow. So narrow was the track that in order to pass the bike and side-car he had to plunge into the drift.

"Pretty thick," remarked Athol.

"Ay, that it is," replied the man. "An' it's worse up yonder."

"Any village about here?" asked Dick.

"Not for some miles," was the reply. "And not a house, if it comes to that."

The man rode on. He seemed loth to waste time in conversation.

"We've struck the worst part of Wenlock Edge, it seems," said Athol consulting his road map. "It would have paid us to have stuck to the Severn valley, only we both wanted to see Ludlow and its castle. Well, ready?"

Dick nodded assent, and restarted the engine. Although the belt slipped frantically the slight friction of the pulley aided the bodily efforts of the lads. By dint of much exertion another hundred yards were covered; then despite their efforts they came to a dead stop.

"How about turning back?" suggested Dick.

"No good," decided Athol. "We might get to the bottom of the hill—might not. It's a moral cert we could not get up the rise on the other side of the bridge."

"And we can't leave the bike here," added his companion. "It would completely block the road."

"The road is blocked already, I fancy. The plain fact is this: we're snowed up, and what's more the side-car wheel has gone to pot at last."

"Getthe luggage out, old man," said Dick. "We'll pad the hoof and see if we can find a cottage. We might, with luck, get a fellow with a horse to pull the bike to the top of the hill."

"I guess the job's beyond the powers of a gee-gee," remarked Athol, who, ankle-deep in snow, was unstrapping the luggage from the carrier. "We'll have a shot at hiking the show into the drift. It seems fairly firm snow on this side."

By dint of strenuous efforts the two lads succeeded in lifting the heavy side-car to the fringe of the road, leaving a space of less than six feet between the wheel of the car and the snow-bank on the opposite face of the track. Then, shouldering their belongings, the weather-bound travellers trudged stolidly up the hilly road.

"Here's a jamboree!" exclaimed Dick after a long silence. He was regaining his breath and with it his exuberant spirits. "We'll have something to remember. By Jove, isn't this a ripping country?"

"It's all very fine," said Athol guardedly, "but, remember, we may be held up for a fortnight. This stuff takes a jolly lot of thawing, you know. Hulloa! There's someone hammering."

"The child is correct," declared Dick with a laugh. "And hammering metal work. I believe our friend the horseman was a little out in his statements. There must be a human habitation of sorts, and, judging by the direction of the sounds—unless the acoustic properties of a snowstorm are erratic—the fellow is tinkering away on that hill on our right. Yes, old man, here's a gap in the hedge. It looks remarkably like a carriage drive."

For the last hundred yards the road was bounded by a raised bank surmounted by a thick laurel hedge. The gap that was just beginning to become visible resolved itself into a pathway barred by a tall gate tipped with a row of formidable spikes.

"Wonder there isn't an array of notice-boards of the 'Trespassers will be prosecuted' order," remarked Athol. "It seems to me that no one has used this path since it started snowing. However, it must lead somewhere, so let's investigate."

Lifting the rusty latch the two lads pushed hard against the gate. They had to force the bottom bars through eighteen inches of snow before they could open it.

The hammering noise was still maintained with hardly a break. The workman, whoever he might be, was certainly industrious.

For fifty yards the path ran straight up a steep ascent and then bore abruptly to the left. Here Athol and his chum were confronted by another gate which, unlike the outer one, was secured by a stout padlock and chain. On either side ran a laurel hedge almost as tall as the one separating the grounds from the highway. To the right hand gate-post was attached a socket supporting a large bell, the clapper being worked by means of a chain.

"I say, looks a bit fishy, eh?" remarked Dick, regarding the barrier with interest. "P'raps we've struck a private asylum."

"Don't know. Suppose if the owner wants to keep tramps and stranded wayfarers out, he's quite at liberty to do so," replied Athol. "However, necessity knows no law, so let's agitate the piece of sounding brass."

He jerked the chain. The bell rang out with startling loudness, the vibrations echoing and re-echoing between the pine clumps. The hammering ceased abruptly.

An old man, supporting himself by means of a stick, ambled through the snow, appearing from behind the hedge on the left of the gate. He was apparently about eighty years of age, wizened featured and white haired.

"What do you want?" he asked in a quavery voice. "My master sees no one except by appointment. If you have one, well and good; if you haven't, 'tisn't any use your stopping here."

As he spoke he made a snapping sound with his fingers and, in answer to the signal, two enormous bull-terriers lolled sullenly to the old man's side, and with the precision of a pair of music-hall twins, each bared his formidable teeth and growled menacingly.

Athol stood his ground. The chilliness of his reception had "set his back up."

"Look here, my man," he said with asperity. "You've done your duty by warning us, now go and tell your master that he is wanted—and look sharp about it."

Then, seeing the old fellow hesitate, he added,

"Sharp about it, I said. I'm not used to giving the same order twice."

"And I am not used to having my servants ordered about by strangers," exclaimed a deep, well-modulated voice. "Since your business seems urgent perhaps you will kindly state it."

The speaker was a tall, finely built man of about forty years of age. His features were clear cut, his brow lofty, and his jaw massive. He was clean shaven, revealing a pair of tightly pursed lips. His complexion was pale, his eyes of a deep blue colour and set rather wide apart beneath a pair of bushy, overhanging brows. Across his forehead was a horizontal scar of old standing, showing white even in contrast to his greyish complexion. His hair was dark brown tinged with grey and growing high upon his temples.

"We called to ask for assistance," began Athol. "Our motor-bike——"

"Mechanical breakdown?" asked the occupier of the premises.

"No; we're snowed up, and the side-car wheel has given out," announced the lad.

"H'm; well, I'm glad it isn't an engine fault," remarked the stranger. "Had it been you would have had no sympathy from me. A fellow who cannot tackle a refractory engine ought not to be allowed in charge of one on the road. Where's your bike?"

"About a hundred yards down the hill and in a snow-drift," replied Athol. "We did our level best but the snow was too much for us. We thought, perhaps, that we might find someone who has a horse——"

"Horse," repeated the man. "It will want something better than a horse, I'm thinking. Open those gates, Harvey, and look sharp about it. Come in, both of you. I'll be with you in a couple of minutes."

He gave the lads an approving smile as they both walked past the bulldogs without the faintest hesitation. Then he disappeared up the path, while the gatekeeper, having opened and unfastened the massive portal, vanished between the laurel hedges.

"We've struck a rummy show, old man," whispered Dick. "The old chap isn't a bad sort, though. Wonder what he is going to bring out? A traction engine?"

Tracey's curiosity was speedily set at rest by the reappearance of the stranger, dragging behind him a sleigh. The contrivance had no runners; it consisted merely of a rectangular sheet of metal curled at the foremost end. On it were thrown a couple of fir planks, about six feet in length, and nine inches in breadth.

"It's quite easy, thanks," said the stranger, declining the lads' offer to assist in dragging the sleigh. "It's made of aluminium. You will have to bear a hand when we get the bike on it. Best foot forward. I have a lot of work to finish before lunch, you know."

"Threaded?"

"Yes, we cut the threads before we left."

"Good men!" exclaimed their benefactor approvingly. "You both seem of a mechanical turn of mind. Well, you can set to work. If there's anything you require ring that bell. Lunch will be ready in an hour and twenty minutes. If you haven't finished by that time there's four hours between that and teatime. Excuse me, I must be off."

The shed was well lighted and warmed by means of hot water pipes. In one corner was a portable forge, in front of one window an up-to-date lathe. Engineer's tools, all in excellent condition, occupied racks on the walls, while on the beams overhead were bundles of white metal rods and stacks of aluminium sheeting.

"We've fallen on our feet, old man," remarked Dick. "Lunch, too, by Jove! I'm hungry. Our scrumptious repast at Shrewsbury is but a pleasant memory. I could do a jolly good tuck-in now."

"Nothing like work to while away the time," asserted Athol, casting off his motor-overalls and coat and rolling up his sleeves; "Buck up, old fellow, and rip that tyre off."

Soon the two young tourists were hard at it, and none was more surprised than they were when the door of the shed was opened and their host exclaimed,

"Spell-oh! Down tools, lads. Why, you have made a show. You'll find some cleaning stuff in that tin. I'll take you to the bathroom in the house."

"'Fraid we're in a jolly pickle," said Athol apologetically.

"I'm used to that," rejoined the stranger, as he led the way to a substantially-built stone-house standing in an open space between the pine-trees. "If you like to take off your boots—they look pretty saturated—I'll lend you some slippers."

Having washed, the lads were ushered into a long dining-room. The table was laid with covers for three. An old manservant, who might have been a brother to the gatekeeper, waited until the diners' wants had been attended to; then having thrown a couple of logs upon the already briskly glowing fire, he went out.

"Now to business," exclaimed their host. "First let me introduce myself. My name is Desmond Blake. My age—an important consideration in these strenuous days—is forty-two; my profession, an engineer who has been cold-shouldered by a—but that can wait. Now, tell me, what are your names? And what brings you in these parts?"

"It'sa long story," began Athol, having first given their questioner their names. "We don't want to bore you, Mr. Blake."

"Not at all," the host hastened to assert. "I am all attention."

"Suppose I ought to go back to the early stages of the war," said Athol. "You see, one yarn does for both of us, since we share and share alike. Fifteen months ago we were at a boarding-school in the south of England. It was only a small affair. We were prefects and all that sort of thing, and had practically finished our education before entering an engineering college. Dick's father is a major serving in Mesopotamia, my governor is a lieutenant-colonel and a prisoner of war at Meseritz. We have no relatives left in England. After a time we ran away from school and enlisted. You see, we are fairly big fellows and somehow we couldn't hang back. The training part wasn't half bad, although we had a couple of gypsies, an ex-convict, and a solicitor as billet-mates. Then we did five months in France, and got on jolly well until we were both offered commissions. That put the hat on the show."

"How was that?" asked Mr. Blake.

"The colonel sent us back to the regimental depot, and while our papers were under consideration the War Office made us produce our birth certificates. Then they found out that we were both under eighteen, so they pushed us out of the army—worse luck."

"Wouldn't even give us a chance to go back to the ranks," added Dick. "And we were having quite a good time. We'd stuck it through the best part of the winter, and the warmer weather was coming; but it was no use. They turned us down."

"And so we thought we'd have a fling before we settle down to engineering," continued Athol. "We both have a little money. We bought the motor-bike and side-car—got it dirt cheap from a fellow who was going to join up. We started off through the Midlands, were in the thick of the last Zepp raid in Northampton, went on through Newark, York, Halifax, and Lancashire, and then to Cheshire. From thence to Shrewsbury and here we are."

"What regiment were you in?" enquired their host.

The lads produced the documents that had effectually floored the recruiting sergeants at Shrewsbury. They were their discharges from the Loyal North Lancashires.

"Wonder, with your mechanical turn of mind, that you hadn't tried for the Royal Engineers or the Flying Corps," remarked Mr. Blake.

"We did have a shot at the R.F.C., but there were no vacancies at that moment," explained Athol. "We were rather cut up about it. But we did see some flying out there. Once we saw our monoplanes bring down a couple of Taubes one after the other; but sometimes we saw what we didn't want to see—our machines outclassed by those Fokkers. The brutes have the advantage, you know. They climb much more quickly than ours. It's not that they are more powerfully engined. It's the design. Our fellows are frightfully keen, but they are handicapped."

"You seem keen on aviation?"

"Rather," replied Athol, enthusiastically.

"Then, perhaps, my modest workshop may interest you," remarked Desmond Blake. "Pon' my word I don't know why I should allow you to inspect my work; I have kept it a strict secret so far, even dispensing with a staff of assistants in order to be untrammeled by the unwelcome visits of more or less incompetent factory inspectors."

He paused, pondering over in his mind some debatable point.

"By Jove!" he exclaimed, noticing his guests' empty soup plates. "We're supposed to be at lunch, and I had forgotten the fact."

In answer to a summons on a bell the old servant reappeared, deftly removed the plates and served the second course. This done, he went out.

"Since you have given me a résumé of your career," said Mr. Blake, "perhaps you might like to hear mine, at all events since the momentous day, the fourth of August, 1914.

"At the outbreak of hostilities I was in South America, doing remarkably well in mining engineering. A particular hobby of mine was flying, and having made three or four successful experimental machines, embodying features not previously known to aviation, I naturally thought that my experience would be welcome to the War Office.

"Accordingly I settled my affairs out there with the utmost dispatch and hurried home. My first interview with the authorities at Whitehall was decidedly frigid. They were awfully polite, but somehow they failed to come to any practical decision. Wanted a scale model, as if that would serve the same purpose as the actual machine I proposed to submit. I offered to have a battleplane complete, including engines, for inspection and test within fifteen days, but I was informed that this was unnecessary until the plans had been inspected by a sub-committee.

"Altogether half a dozen sub-committees tried their hands with my plans and specifications. Afterwards I discovered that hardly a single member knew anything about practical flying. Some of them hardly knew the difference between an airship and an aeroplane—asked questions on a par with those of the Yankee senator at the 'Titanic' enquiry.

"Without going into details I may say that my offer to the War Office was finally declined with thanks. I had no better luck with the Admiralty, for directly they learnt that the War Office had 'turned me down' I was metaphorically shown the door.

"I warrant that if I were a renegade and had taken my plans to Berlin the German government would have snapped them up, either by fair means or foul. As it is, their agents have been giving me a deal of trouble.

"However, foiled in my patriotic efforts I determined to erect a private factory, build a really formidable battleplane and give a practical demonstration over the heads of the War Office. My first trouble was to find a suitable site. It had to be in a remote district, far from a prohibited military area, yet fairly accessible from the important industrial centres. I lighted upon this place, and found it answered my purpose.

"Everything I have to do single-handed. I dare not run the risk of getting mechanics to help, partly, as I said before, owing to the Factory Act restrictions, but more especially from a fear lest my ideas should be filched.

"And now the finished article lies in my grounds, ready for instant flight, except for one drawback——"

"The snow, I suppose," hazarded Dick.

"Does not affect it to any appreciable extent," rejoined Desmond Blake. "My battleplane does not require hard, level ground for a 'take-off.' It will rise almost perpendicularly. No, it is not the climatic elements. To be concise I need a couple of capable and willing helpers, and judging by what you have already told me, I think you fellows have sufficient patriotism to volunteer your services in that direction. Am I right?"

Dick gave his chum an enquiring glance. Athol, naturally cautious, knew that Dick would have jumped at the offer.

"Your tempting invitation needs thinking over," replied Athol. "We should——"

"Of course," agreed Desmond Blake. "Of course. Suppose you defer your decision until you have inspected my invention? You will, I feel sure, treat the subject as one of a highly confidential nature."

"Rather," agreed both lads simultaneously.

"I knew you would," continued their host. "In any case you will be here a week at least, for the snow lies about a long time, and the roads will be simply impassable for motor traffic during the thaw. That is, if you decide to continue your journey by motor. There is always a means of getting to Church Stretton on foot and taking train from there. On the other hand, if you decide to remain, my house is at your disposal."

"You are awfully kind," said Athol.

"With an ulterior motive," added Desmond Blake. "You are the very fellows I was looking for. I want to 'rope you in.' That's speaking bluntly. I believe in saying what I mean without beating about the bush."

"You mentioned that you had trouble with the German agents," remarked Dick.

"I have reason to believe so," replied Blake. "I have no conclusive proofs. I can only infer that spies are at the bottom of the trouble. On three occasions my grounds were broken into. My gatekeeper, Harvey, a tough old chap in spite of his years, was able to thwart two attempts to break into my workshop. On the third instance I scared the intruder pretty badly by means of a shock with a high tension wire. At the same time the automatic shutter of a camera was released in the hope of getting the likeness of the gentleman in question. Unfortunately the magnesium flashlight failed to explode at the same moment as the exposure of the lens. What I ought to have done was to leave the lens uncovered. I shall know better next time."

"Wouldn't the plate become fogged?" asked Dick, who was a successful amateur photographer.

"Oh no; you must remember the attempt was made at night. The sudden flash of the magnesium acts much the same as the brief exposure of the plate in daylight."

The meal proceeded slowly, while conversation flowed briskly. Desmond Blake knew the value of a good lunch as an incentive to amiability, and had played his cards well. "Now for the hangar," he said, at the end of the meal. "You smoke? No, good; I'm glad to hear it. It's an expensive habit, although I have a great weakness in that direction. In fact, I sometimes find myself on the point of smoking a pipe in the petrol store."

"We've seen fellows in the Royal Flying Corps drop the glowing ends of their cigarettes in petrol just for sheer mischief," said Dick. "Nothing happened."

"But it might have," rejoined their host. "'Fraid it doesn't speak for the good quality of the petrol or the common sense of the men who fool about with it. It isn't the liquid petrol that is dangerous, but the vapour it gives off. I've been experimenting in that direction, trying to get a spirit that is non-inflammable under normal atmospheric pressure and only exploded when under compression."

"Have you been successful?" asked Athol.

"To a certain extent; that is to say, I have treated petrol so as to make it unresponsive at ordinary pressure except to a very hot spark."

Still conversing Desmond Blake led the way from the house, through a dense belt of pine trees, to a small clearing. The greater part of this space was occupied by a galvanised iron shed, at one end of which were large double doors. Between the threshold and the nearmost trees there was a distance of roughly ninety feet, the trees themselves exceeding a hundred and twenty feet in height.

"Here's the hangar," announced their guide, indicating the shed.

"Curious situation, if you don't mind my saying so," observed Athol. "You'll have to cut down more of those trees before the biplane is able to take flight."

"On the contrary there is more 'taking-off' space than is absolutely necessary, and, I might add, the machine is not a biplane. It is fashioned, as far as possible, on the principle of a bird, and unless my memory plays me false, I know of no bird possessing more than two wings. But here we are."

Desmond Blake rolled back one of the doors of the shed. The other, actuated by means of a flexible wire running over pulleys, slid back too.

"Merely a labour-saving device," said Blake. "I based my calculations upon a one-man show. But what do you think of her?"

In the dazzling reflected light from the snow the battleplane stood revealed to the lads' eager gaze. At first sight it hardly resembled a flying machine. It was more like a huge cigar raised at an angle of forty-five degrees and supported by a pair of trellis girders each of which in turn terminated in a couple of pneumatic-tyred wheels. The planes were folded against the fuselage; there were no signs of aerilons, horizontal or vertical rudders and other contrivances common to aeroplanes. This creation had the appearance of a gaunt, featherless bird standing erect on a pair of spidery legs.

"What propels it?" asked Dick. "Where is the propeller? And the planes? You said it was not a biplane. To me it looks like anonplane. Hope I am not asking too many questions," he added apologetically.

"Fire away; as many as you like," rejoined Desmond Blake. "In the first place there is no propeller, that is, if you mean a rotary one. To go back to the simile of birds; they don't cleave through the air under the action of a two-bladed propeller. That, after all, is a tacit admission by aeronautical engineers that they are unable to copy nature; so they make a substitute that fails to perform the relative task that a bird's wings do with seemingly little effort. I have dispensed with a propeller and substituted mechanical planes that approximate very clearly the natural method of flying. Before I explain further we must get aboard; I'll show you the way. One could make use of a pair of steps, but they would be awkward things to carry about, especially at the Front."

With remarkable agility the inventor swarmed up a light aluminium ladder built into the girder-legs of the battleplane. Thirty feet up he disappeared from view through an aperture in the underside of the fuselage.

In a trice Dick followed, Athol ascending with more deliberation. The latter was puzzled at the great rigidity of the aluminium girders. Evidently Desmond Blake had solved the task of making the metal as tough as steel without any marked increase of weight. Another thing Athol noticed was that all the cross sections of the latticed girder were pear-shaped, the blunt end facing the direction of flight, the tapering end being aft. This was expressly for the purpose of reducing the friction of the air.

Squeezing through the trap door the lads found themselves on the floor of the chassis, which was composed of a succession of broad steps on inclined planes in order to afford a firmer footing when the battleplane was at rest. Between the floor and the curved roof or deck there was sufficient space for a tall man to stand upright. Against the concave sides were folded cots, in which those of the crew "off duty" could sleep during prolonged flights, while at approximately one-third of the length of the fuselage from the blunt nose was the motor room, a veritable nest of intricate, lightly-built and powerful machinery.

"Do you work the battleplane entirely from under cover?" asked Athol.

"Oh no," replied Desmond Blake. "It is essential to have a wide field of outlook. Here is the pilot's seat. Get in and see what it is like."

He indicated a circular seat perched about a foot beneath the deck, from which an oval-shaped opening provided with a raised coaming had been cut. Overhead was a light metal canopy which, when required, could be lowered flush with the top part of the chassis. To gain the seat from the floor of the fuselage it was necessary to make use of a metal ladder.

"Steady yourself by that horizontal bar," cautioned the inventor, indicating a short rod on the fore side of the coaming.

The warning was necessary, for, as Athol slid into the seat, the seat slid from him. It was only by hanging on to the bar and allowing his feet to dangle in the air that the lad saved himself from falling four or five feet to the floor.

"Don't say that I didn't give you fair warning," exclaimed Desmond Blake, while Dick laughed at his friend's predicament. "Now, have another shot at it. Lift yourself fairly into the seat. That's it."

"What's the idea?" enquired Athol.

"There are four seats like that, and each one is gimballed. That is, it is suspended in a similar manner to a compass on board ship, so that in spite of the motion the sitter is always 'right side up.' No matter how the battleplane banks, nose-dives, or even 'loops the loop,' the crew, seated in their allotted stations, are always in a natural position."

"That I can see," said Dick. "But how is a fellow to see where's he going when the plane is upside down? In that event his head and shoulders are inside the fuselage."

"Only for a few moments," replied the inventor. "The plane is self-righting, provided, of course, there is 'air-room.' Just give a glance at your friend's feet. No, there's nothing wrong with them. That's not what I meant. His feet are resting on a step, behind the step is a sheet of burnished metal inclined at an angle of forty-five. Now, in the event of the 'plane turning over on its major axis that mirror would project below the inverted deck of the chassis, and thus the pilot would still be able to 'look ahead.'"

Facing the pilot's seat were a few indicators and levers, whereby the altitude and speed of the plane could be determined and the aircraft steered on her course. A voice-tube communicated with the motor-mechanic who occupied the third seat. The second and fourth seats were raised slightly above the others, and were intended for the machine-gunners.

"The offensive armament is not yet on board," explained the inventor. "I have turned out a couple of automatic weapons firing eight hundred shots a minute. Here is one of the cartridges," he continued, drawing a metal cylinder from his pocket. "The calibre is 303, the same as that of the small arms of the British Army, but you must observe that the bullet is longer and different in other respects."

"It certainly is longer," agreed Dick, as he handled the cartridge. "But beyond that I see no difference."

"Do you notice a minute line round the bullet?" asked Blake. "The projectile is made in two parts. On leaving the muzzle the parts fly apart, but are held together by a length of flexible wire. Thus each bullet resembles a miniature chain-shot of the days of the old wooden walls. A hostile plane would stand little chance if under the fire of a hail of these bullets. There would be no clean holes in the fabric; struts and tension wires would be severed and the whole contraption would fall like a stone."

"Then what propels the plane?" asked Dick, his interest in the motors claiming precedence above all other constructional details.

"This pair of engines, each of two hundred horse-power," was the reply. "See, I actuate this lever and the wings—I prefer to call them wings rather than planes—unfold."

Swiftly, yet with an even movement, wings, hitherto lying snugly against the chassis, were outspread. Taking into consideration the length of the battleplane from nose to tail—barely fifty feet—the space from tip to tip of the wings looked disproportionately small. Each wing projected fifteen feet from the side, and curved backwards like that of a bird. The fabric from which the wings were made was composed of thin, specially-treated aluminium, in plates overlapping each other like tiles on the roof of a house.

"Now, Tracey," continued Desmond Blake, "see if you can coax the motors to start. If you can manage a car-engine you will be able to get them to fire. There's no danger of the bird taking flight. She's pinned down to the floor securely. At the same time I don't think I would run the motors all out, if I were you."

Deftly Dick set to work turning on the petrol and flooding the carburettor.

"Is it necessary to prime the motors?" he asked.

"They ought to fire without," replied the inventor. "There's the self-starter—that lever on your right."

At the first attempt the engines fired easily. In spite of being in a confined space there was very little noise, thanks to the efficient silencer. It was doubtful whether the purr of the motors could be heard beyond the limits of the grounds.

Yet, although the fabric of the battleplane trembled under the pulsations of the motors, the wings remained motionless save for the vibration imparted to the whole contrivance. Seeing Dick's look of enquiry the inventor pointed to a lever close to the lad's right hand.

"Gently with it," he cautioned. Depressing the lever Dick was aware of a terrific air-current rushing overhead. Dead leaves and pieces of aluminium sheeting that were lying on the floor of the shed were whisked up and flung about with great velocity. Peering over the edge of the coaming Dick could see that both wings were now beating the air with terrific violence, being actuated by a number of rods working on concealed cams. Supplementary rods imparted a second motion to the wings, the innermost and rearmost edges of which moved up and down independently of the primary movement of the fore part.

Stretching out his hand the inventor cut off the electric current, and the motors came to a standstill.

"Cannot afford to waste petrol in these hard times," he said with a smile. "You've seen enough to form an idea of how the plane flies. The mere up and down flap of the wings is insufficient; it is the peculiar twist of the after part that does the trick—something after the principle of a man sculling a boat by means of a single oar working over the transom. If he were to waggle the blades of the oar to and fro without giving a dexterous twist nothing would result except a see-saw motion of the boat. It certainly would not move ahead through the water, except for the tortuous movement of the oar."

"I should have thought that the wings were far too small," observed Athol.

"On the contrary they are just the right proportion compared with the weight and power of the motors," replied Desmond Blake. "I have not modelled my invention on the lines of an albatross, whose spread of wings is enormous. I had the lark in my mind's eye. That little bird, as you know, soars almost perpendicularly, yet the wings are small in proportion to the size and weight of its body. Now you have had a general idea of the secret battleplane. To return to the attack: are you fellows willing to sign on as crew?"

"Rather!" replied both lads without hesitation.
