APRIL 1901.
I wonderhow many people have had the pleasure of a trip to the Bell Rock Lighthouse. I don’t mean the customary trip per summer steamer, which keeps at a very respectable distance, and gives one but a faint idea of what the building is really like; but those who have made a landing on the Rock, and spent an hour or two in admiring the ingenuity and skill displayed in the erection of this noble structure, which has so bravely stood the test of almost a century’s storms. It is not my intention to enter into a detailed description of the Lighthouse, but merely to jot down in haphazard fashion any little items which may serve to interest or amuse the general reader. The usual signs which to the landsman’s eye chronicle the passing seasons are here unknown; but to us, the fish, shell fish, marine plants, migratory birds, etc., constitute an endless calendar. Early this month the flocks of eider and long-tailed ducks, which have been in close attendance since September, have gone housekeeping, and one belated pair of eiders alone remain, evidently as undecided as some of their human contemporaries about taking the important step. The gulls, which have been levying blackmail from the ducks all winter, have almost all disappeared, and we miss their raucous voices at our door, contending for the after-dinner scraps. One would scarcely credit the swallowing capacity of these omnivorous birds. A piece of ham skin, nine inches long and three inches broad, and about the consistency of sole leather, was greedily bolted by a blackback without apparent effort. These birds, though not classed as divers, I have frequently seen go completely under water to recover a sinking tit-bit. I had an interesting view from the balcony the other morning of a seal which was breakfasting off a full-sized cod which he had just captured. Seizing the fish by the shoulders in his teeth, and pushing it from him with his fore flippers he tore off a great strip clear to the tail. Elevating his head in the air, he gulped it over. Diving after the disappearing fish, he quickly had it on the surface again, and the pushing and tearing repeated till there was nothing left but the head and backbone. A couple of gulls kept circling and screaming over him, picking up any strayed pieces which came their way, but he took good care their share was small, and kept a wary eye on their movements, evidently suspecting they had designs on the fish itself. They, in turn, I noticed, always kept their wings elevated when resting for a moment on the water awaiting his reappearance with the fish, prepared to shoot into the air should he attempt to rush at them.
The white whelk, whose numbers here are legion, are now making their appearance from their winter quarters, where, in sheltered nooks and crannies, they have successfully resisted the winter’s gales. Unlike some of their species, which subsist solely on marine plants, they are not vegetarians, but, spreading themselves over the Rock like a devastating army, they devour all animal matter they come across. Armed with a strong muscular proboscis, containing within itself the necessary boring apparatus, and which consists of a cylindrical implement, the extremity of which forms the mouth of the animal, and is surrounded by two strong muscular lips, enclosing a tongue, armed with spines, they are able, by the joint action of tongue and lips, to perforate the hardest shells. Fixing itself on the defenceless mussel, the boring operation is carried on through the furrow on the one side of the rim of the whelk, and a neat cylindrical orifice, no bigger than a pinhole, is eventually made in the mussel shell, through which the tongue is thrust and the contents gradually extracted. Two years ago the Rock was literally covered with patches of immature mussels, but is now completely denuded by these rapacious hordes. Some seasons the mussel spawn is pretty much in evidence here, but they never come to maturity; the white whelk takes care of that; but apart from that cause, it is doubtful if they could manage to subsist in such a boisterous situation. The workmen, while employed here in the building of the Lighthouse, in order to regale themselves with a fresh diet occasionally, made the experiment of transplanting mussels from the shore, but without success. The white whelk was evidently considered the chief offender, as barrels of them were collected and destroyed without any appreciable diminution of their numbers. The attempt was ultimately abandoned in disgust.
“All is not gold that glitters,” neither does every whelk shell enclose its legitimate owner. Pick up that one which moves with such unusual speed through this shallow pool, and you will find a pair of lobster like claws dangling from its mouth. Gently crack theshell—for you will find it next to impossible to extract him aliveotherwise—and you will see, what one may be pardoned for supposing, a miniature lobster, but which in reality belongs to another distinct species, namely, the hermit crab. Whether he has obtained occupancy by force of arms or merely through decease of the original tenant is a moot point, but the first supposition is highly probable, as he is a most belligerent little customer. An amusing sight may be witnessed by placing several of them, deprived of the shells, in an ordinary soup plate, with a little sea water and some emptyshells—fewer shells than crabs. The fighting and struggling to secure houses is ludicrous in the extreme. One may be seen almost successful in mooring himself within ashell—which, by the way, is effected by means of the shelly plates at the extremity of his soft, twistedtail—when another seizes him by the nape of the neck, as it were, and he is dragged reluctantly forth. The evictor still holds him struggling at claw’s length, and not until he himself is safely ensconced does he relinquish his grasp. Others, again, may be seen prospecting the interior of a shell. Extended at full length on the top of the shell, with their claws groping within, one is forcibly reminded of a person “guddling” for trout. Should there be any portion of the original whelk remaining in the shell, this, after repeated tuggings, is cleared out. The tail is then inserted, and the whole body withdrawn into the shell, providing it is large enough; if not, he stands a bad chance of being evicted by the next pugnacious house-hunter.
