About three centuries ago, in 1696, a Russian, one Ludloff by name, described some bones belonging to what the Tartars called "Mamantu"; later on, Blumenbach pressed the common name into scientific use as "Mammut," and Cuvier gallicized this into "Mammouth," whence by an easy transition we get our familiar mammoth. We are so accustomed to use the word to describe anything of remarkable size that it would be only natural to suppose that the name Mammoth was given to the extinct elephant because of its extraordinary bulk. Exactly the reverse of this is true, however, for the word came to have its present meaning because the original possessor of the name was a huge animal. The Siberian peasants called the creature "Mamantu," or "ground-dweller," because they believed it to be a gigantic mole, passing its life beneath the ground and perishing when by any accident it saw the light. The reasoning that led to this belief was very simple and the logic very good; no one had ever seen a live Mamantu, but there were plenty of its bones lying at or near the surface; consequently if the animal did not live above the ground, it must dwell below. To-day, nearly every one knows that the mammoth was a sort of big, hairy elephant, now extinct, and nearly every one has a general idea that it lived in the North. There is some uncertainty as to whether the mammoth was a mastodon, or the mastodon a mammoth, and there is a great deal of misconception as to the size and abundance of this big beast. It may be said in passing that the mastodon is only a second or third cousin of the mammoth, but that the existing elephant of Asia is a very near relative, certainly as near as a first cousin, possibly a very great grandson. Popularly, the mammoth is supposed to have been a colossus somewhere from twelve to twenty feet in height, beside whom modern elephants would seem insignificant; but as "trout lose much in dressing," so mammoths shrink in measuring, and while there were doubtless Jumbos among them in the way of individuals of exceptional magnitude, the majority were decidedly under Jumbo's size. The only mounted mammoth skeleton in this country, that in the Chicago Academy of Sciences, is one of the largest, the thigh-bone measuring five feet one inch in length, or a foot more than that of Jumbo; and as Jumbo stood eleven feet high, the rule of three applied to this thigh-bone would give the living animal a height of thirteen feet eight inches. The height of this specimen is given as thirteen feet in its bones, with an estimate of fourteen feet in its clothes; but as the skeleton is obviously mounted altogether too high, it is pretty safe to say that thirteen feet is a good, fair allowance for the height of this animal when alive. As for the majority of mammoths, they would not average more than nine or ten feet high. Sir Samuel Baker tells us that he has seen plenty of wild African elephants that would exceed Jumbo by a foot or
