THE OPEN LETTER

In about three weeks vacation days will be over and the fall season for reading clubs and home reading circles will begin. There are hundreds of clubs using The Mentor—some as their regular course for the season, others as supplementary to their own courses. During June we had many demands from reading clubs for information concerning The Mentor plans for next year. This information was wanted in most cases for use in club booklets which were then in course of preparation. In order to meet the needs of reading clubs we prepare plans of The Mentor far ahead. Our numbers for the year 1917 are already scheduled, and some of them are in actual preparation. Our descriptive booklet tells all about future as well as past numbers.

I do not think that the members of The Mentor Association who are not active in reading clubs appreciate what The Mentor is doing for club work. We could make up a book many times the size of The Mentor simply out of the letters of appreciation that we have received from clubs all over the country bearing testimony to the service that we give. The following, just received, is a fair example:

“Some time ago you sent me a suggested program for the study of South America. The club of which I am president has just voted to study that subject, and they are following the program that you laid out, and it is so much better than anything that we could have laid out for ourselves that it saves the program committee a great deal of work. We hardly see how you can afford to do this, but we want to express our appreciation.”

This letter is really typical. A great many ask us how we “can afford to do this work” for nothing. Some offer to pay. So let us make it clear now to every member of The Mentor Association that the preparation of special programs and courses of reading is a regular part of The Mentor Service, and that we give it freely and gladly. The service includes other things besides. We answer questions on all kinds of subjects in the various fields of knowledge. Our daily mail is heavy with inquiries, and we give the questioners the benefit of the knowledge and experience of recognized authorities.

Just another word about programs. Some people do not understand what a program for a reading club means. The ordinary program is so slim and elementary that there is no inspiration in it. We prepare programs that contain the meat of the subject in condensed form, and we supply appropriate introductions to the meetings, and suggest supplementary reading matter. In special cases, such as that of a music course, we furnish lists of appropriate compositions to be played in the meetings as illustrations. We make programs on many subjects. Of course we look forward to a time when it will not be necessary for us to make special programs on most subjects, because they will be covered in The Mentor itself. At present we supply a special program on South America. This will not be necessary in another year, for we shall have a series of Mentors that will cover South America, and they will supply all the material necessary for clubs studying the subject. The first number in the South American series has just appeared, so Mentor readers can judge of the character and scope of these numbers.

Write in at once and get our booklet descriptive of The Mentor Service. In this booklet we have arranged The Mentors in special courses, suitable for any number of meetings of a club, from three up to twenty or thirty. We also give full directions as to the use of The Mentor in a reading club. Read this booklet and you will find that The Mentor is not only a source of pleasure and profit in its unit form as it appears twice a month, but that each unit is a stone in a rapidly growing structure. There is no need of talking about what it will look like when this structure is completed, for of knowledge there is no end. The Mentor institution will simply go on growing. In three years of existence, it has already come to assume an impressive aspect with its array of interesting departments, each rich in information and beautiful illustration. You will appreciate this if you send for our book, and read it.

ELK

Monograph Number Three in The Mentor Reading Course

The American elk or wapiti (Cervus canadensis) is as large as a horse, handsomely formed, luxuriantly maned, carries its head proudly, and is crowned by a pair of very imposing antlers. The male elk is at its handsomest in October or November, when his skin is bright and immaculately clean and his fine antlers have just been renewed.

The elk has small and shapely legs. It avoids swamps and low ground and likes to frequent mountain parks. It is also a forest animal. Formerly it ranged far out into the western edge of the great plains and it was accustomed in summer to ascend the Rocky Mountains to the very crest of the Continental Divide. To-day, however, it is abundant in one locality only—the Yellowstone National Park and the country immediately surrounding it. Elk are also found in small numbers in Washington, Oregon, Colorado, Montana, Idaho and on Vancouver Island, British Columbia. However, elk are easily bred in confinement, and many good herds have been established in great private game preserves. In addition to these, there are many small herds in private parks.

The elk sheds its antlers each year. The antlers of one of the largest males in the New York Zoological Park dropped on March twenty-first nine hours apart. On April 8th each budding antler looked like a big brown tomato. Ten days later the new antlers were about five inches long, thick and stumpy. By May 10th the elk was shedding its hair freely. On June 18th the antlers were at full length. By August 1st the short red summer coat of hair was established, and the antlers were still “in velvet,” The elk then began to rub the velvet from its antlers against the trees.

By September 15th the summer coat of the elk herd had been completely shed. On October 1st the entire herd was at its best. All antlers were clean and perfect. The hair of the skin was long, full and rich in color. This is the mating season of the elk when the bulls are aggressive and dangerous.

Elk are often very unsuspicious and at times so stupid that hunting them is not so exhilarating a sport as it might seem.

MOUNTAIN SHEEP

Monograph Number One In The Mentor Reading Course

The mountain sheep (genusOvis) is a gallant mountaineer. It is a fine, sturdy animal, keen eyed, bold, active and strong, and is always found amid scenery that is grand and inspiring. Its favorite pastures in summer are the treeless slopes above the timber-line; and even in winter, when the raging storms drive the elk and deer down into the valleys, the mountain sheep descends for only a short distance. The mountain sheep is a bold climber. Its legs are robust and strong, and when pursued it can dash down steep declivities in safety.

It is very easy to recognize any adult mountain sheep by the massive round curving horns. No wild animals other than wild sheep have circling horns.

The largest of specimens of wild sheep are found in Asia. There are six species in America. They are scattered from the northern states of Mexico through the Rocky Mountains, almost to the shore of the Arctic zone.

The young of the mountain sheep are born in May or June above the timber-line if possible, among the most dangerous and inaccessible crags and precipices that the mother can find. The lamb’s most dangerous enemy is the eagle, and often the mother cannot protect her young from this foe.

Probably the most familiar of the mountain sheep is the big-horn or Rocky Mountain sheep (Ovis canadensis). Formerly this was quite abundant, but so persistently has it been hunted that the species exists now only in small numbers and in widely separated localities.

The general color of the big-horn is gray brown. They are well fed all the year round. The female has not the long curving horns of the male. Her horns are small, short, erect, and much flattened, in length from five to eight inches.

Other species of mountain sheep are the California or Nelson’s mountain sheep (Ovis nelsoni) a smaller animal than the big-horn and of a pale salmon gray color; the Mexican mountain sheep (Ovis mexicanus) found in the state of Chihuahua, Mexico; the white mountain sheep or Dall’s sheep (Ovis dalli) of Alaska, whose hair is pure white, when it has not been stained by mud or dirt; the black mountain sheep (Ovis stonei) of northern British Colombia, which is distinguishable by the wide spread of its horns, the dark brown color of its sides and the white abdomen; and Fannin’s mountain sheep (Ovis fannini) a newly discovered species which was found first on the Klondike River, Alaska, in 1900.

ROCKY MOUNTAIN GOAT

Monograph Number Two in The Mentor Reading Course

The Rocky Mountain goat, or the white goat (Oreamnos montanus), is the only American representation of the many species of wild goat-like animals so numerous throughout the Old World. Its habitat extends from northwestern Montana to the head of Cook Inlet, but it is not found in the interior nor in the Yukon Valley. It is one of the most picturesque and interesting wild animals on the continent of North America. It ranges on the grassy belt of the high mountains just above the timber-line. It seems to like particularly the dangerous ice-covered slopes over which only the boldest hunters dare to follow it. On the coast of British Columbia, however, the white goat sometimes descends very near to tide water.

The white goat is odd in appearance. At first glance it seems to be a slow, clumsy creature; in fact, it is the most expert and daring rock climber of all American hoofed animals. The hoofs are small, angular and very compact and consist of a combination of rubber-pad inside and knife-edge outside to hold the goat equally well on snow, ice or bare rock. It is said that goats will cross walls of rock which neither man, dog nor mountain sheep would dare attempt to pass. Sometimes they walk along the face of a precipice of apparently smooth rock; yet in doing so they frequently look back and turn around whenever they feel so inclined. The white goat is built something on the order of a small American bison. Its head is carried low and the horns are small and short. Its hair is yellowish-white. Next to the skin is a thick coat of fine wool through which grows a long outside thatch of coarse hair.

It is an animal of phlegmatic temperament. A story has been told of one goat, whose “partner” had been shot, which deliberately sat down a short distance away and watched the hunter skin and cook a portion of his dead mate.

Its flesh is musky and dry and it is not palatable to white men except when they are exceedingly hungry. Its skin has no commercial value. For these reasons and also because it is hard to reach, the Rocky Mountain goat is not likely to be exterminated very soon.

CARIBOU

Monograph Number Four in The Mentor Reading Course

With the exception of the musk-ox, the caribou is the most northerly of all hoofed animals. This animal not only roams on the vast Arctic waste above Great Slave Lake, known as the Barren Grounds, but it also ranges over the west coast of Greenland, along the edge of the great ice cap and perhaps over the entire coast of Greenland. Wherever the naked ridges and valleys yield it food, the caribou may be found.

The caribou is a rather odd-looking creature. It is interesting to note that Nature has provided it with a body especially made to enable it to brave the terrors of a frigid climate. Its legs are thick and strong and its hoofs are expanded and flattened until they form very good snowshoes. Where a moose sinks in, a caribou is able to walk over snowfields and quaking marshes. The skin of the caribou is covered with a thick, closely matted coat of fine hair; through this grows the coarse hair of the rain-coat. This makes a very warm covering—in fact the warmest on any hoofed animal except the musk-ox. It is like a thick, felt mat.

The caribou is the American reindeer. It has antlers, long and branching. As a species they may be grouped under two heads—the Woodland caribou (Rangifer tarandus caribou) and the barren ground caribou (Rangifer tarandus articus). Each of these two groups may be sub-divided several times. However, it is difficult to distinguish these sub-species. The chief characteristics are minor differences in the antlers, but even here great difficulties are encountered. The antlers are subject to thousands of variations, and as a result no two pairs ever are found exactly alike. It has been said that if ten pairs of adult antlers of each of the so-called nine species were mixed in one heap, it would be almost impossible for even an expert to separate them all correctly into their proper groups.

Of the two great groups, the Woodland caribou roams through the pine and spruce forests and also the prairies of Newfoundland, Nova Scotia, New Brunswick, Northern Maine, Quebec, Ontario and Manitoba. It is a large animal with strength enough to vanquish the strongest man in about one minute. Its shoulders are sharp and high, and its head is held low and thrust straight forward. The Woodland caribou of Maine has a body color of bluish brown and gray. In October, however, its new coat is of the color known as seal brown. Its antlers are short and have more than thirty points. As a whole the antlers have the appearance of a tree-top.

The barren ground caribou is extremely like the average reindeer of Siberia and Lapland. It is a rather small animal with immense antlers. The center of their abundance to-day is midway between the eastern end of Great Slave Lake and the southeastern extremity of Great Bear Lake.

The natural food of the caribou is moss and lichens. In captivity very few survive many months without a regular diet of moss. Full grown Woodland caribou consume about seven pounds of it daily.

It is only necessary to watch a caribou walking to see in this animal the true born traveler. This is one of the most peculiar characteristics of the species. At stated periods in the spring and autumn they assemble in immense herds and migrate with the compactness and definiteness of purpose of an army of cavalry on the march. This is most noticeable on the Canadian Barren Grounds. The herd moves northward in spring and in the early winter moves southward. Several of these monster migrations have been witnessed.

BULL MOOSE

Monograph Number Five in The Mentor Reading Course

Imagine an animal standing between six and seven feet high at the shoulders, its legs four feet long, its neck and body covered with a heavy thatch of coarse, purplish gray hair, and its huge head crowned with massive antlers spreading from five to six feet in width! That is the moose (Alces americanus). It is the largest animal of the deer family. The only way to appreciate a moose is to see an adult animal alive and full of strength, striding through the forests of Canada or Alaska.

The word moose is a North American Indian name which is said to mean “cropper” or “trimmer,” from the animal’s habits of feeding on the branches of trees. The moose can be recognized by its broad, square-ended, overhanging nose, its high hump on the shoulders, its long, coarse, smoky gray hair, and the antlers of the male, which are enormously flattened and expanded. Moose are found in northern Maine, and some other parts of the Northern States, Canada and Alaska.

It is hard to kill a moose. Most of those killed are shot from ambush. In the autumn months the moose hunter may sometimes make a horn of birch bark and, concealing himself beside a pond at nightfall, may by imitating the call of the cow moose attract a bull within shooting distance.

The moose calf is born in May and is at first a grotesque looking creature with long, loose jointed legs and an abnormally short body. By the time the calf is a year old it has taken on the colors of adult life.

Unlike most members of the Deer Family, the moose does not graze. It eats the bark, twigs and leaves of certain trees, and also moss and lichens. It is strictly a forest animal and is never found on open, treeless plains. Being very fond of still water, it frequents small lakes and ponds.

One of the largest bull moose on record was seven feet high at the shoulders and had a girth of eight feet. The largest pair of antlers recorded have a spread, at the widest point, of 78 inches. The weight of the antlers and the dry skull together is 93 pounds.

The bull moose has under the throat a long strip of skin called a “bell.” In the adult male animal this bell is sometimes a foot in length The female moose has no antlers, and out of every thousand females only one has a bell.

In captivity the moose is docile, and affectionate. They have even been trained to drive in harness. But owing to the peculiar nature of their digestive organs, they cannot live long upon ordinary grass or hay. Green grass is fatal to them.

During the deep snows of winter moose herd together in sheltered spots in the forest. They move about in a small area and by treading down the snow form what is called a “moose yard.”

The Alaskan moose has been described as a new species (Alces gigas). It is said to be a giant in size. Ideas of this animal are greatly exaggerated, although it is true that its antlers are really immense.

THE BISON LEADER

Monograph Number Six in The Mentor Reading Course

The American bison or buffalo (Bison americanus) because of its great size and imposing appearance, is the most celebrated of all American hoofed animals. It has been practically exterminated, but now that it is given adequate protection, the buffalo, which breeds rapidly in captivity, has been saved from total disappearance.

The buffalo was first seen by white men in Anahuac, the Aztec capital of Mexico, in 1521, when Cortez and his men paid their first visit to the menagerie of King Montezuma. It was first seen in its wild state by a shipwrecked Spanish sailor in southern Texas in 1530.

Once the buffalo roamed over fully one-third of the entire continent of North America. Not only did it inhabit the plains of the West, but also the hilly forests of the Appalachian region, the northern plains of Mexico, the Rocky Mountains, and even the bleak and barren plains of western Canada. The center of abundance, however, was the great plains lying between the Rocky Mountains and the Mississippi Valley.

In May, 1871, Col. R. I. Dodge drove for twenty-five miles along the Arkansas River through an unbroken herd of buffaloes. According to Dr. Hornaday’s calculation, he actually saw nearly half a million head. This was the great southern herd on its annual spring migration northward. Altogether it must have contained about three and a half million animals. In those days mighty hosts of buffaloes frequently stopped or even derailed railway trains, and obstructed the progress of boats on the Missouri and Yellowstone rivers.

When the Union Pacific railway was completed in 1869, the buffaloes were divided into a northern herd and a southern herd. By 1875 the southern herd had been practically annihilated. Five years later the completion of the Northern Pacific railway led to a grand attack upon the northern herd. Three years later this was almost entirely wiped out.

The future of the buffalo depends upon the National herds and ranges, of which the United States has six game preserves. In zoological parks this animal becomes sluggish and rapidly deteriorates from the vigorous standard of the wild stock.

The largest buffalo ever measured by a naturalist is the old bull which was shot by Dr. Hornaday on December 6, 1886, in Montana, and which now stands as the most prominent figure in the mounted group in the United States National Museum. This is the animal whose picture adorns the ten dollar bill of the United States currency. The height of this buffalo at the shoulders was 5 feet, 8 inches, and its length of head and body to the root of the tail was 10 feet, 2 inches. Its estimated weight was 2,100 pounds.

The buffalo begins to shed its faded and weather-beaten winter coat of hair in March. For the next three months he is a forlorn looking creature. By October, however, the new coat is well along, and in November and December the animal is at its best.

Buffalo calves are born in May and June. At first they are a brick red color, but this coat is usually shed in October.

The flesh of the buffalo very closely resembles domestic beef. In fact, it is impossible to distinguish the difference.
