nearly one inch in breadth, and about the diameter of the body of the animal. Possessed of an exquisite sense of hearing and of feeling the external pressure of objects travelling on the ground, they stop their labors instantaneously on the least alarm; but if you retire from fifteen to twenty paces to the windward of the hole, and wait for a quarter of an hour or so, you see the "Gopher" (the name given to it by the Missourians—Americans) raising the earth with its back and shoulders, and forcing it out forward, leaving the aperture open during the process, and from which it at times issues a few steps, cuts the grasses around, with which it fills its pouches, and then retires to its hole to feed upon its spoils; or it sometimes sits up on its haunches and enjoys the sun, and it may then be shot, provided you are quick. If missed you see it no more, as it will prefer altering the course of its burrow and continuing its labors in quite a different direction. They may be caught in common steel-traps, and two of them were thus procured to-day; but they then injure the foot, the hind one. They are also not uncommonly thrown up by the plough, and one was caught in this manner. They have been known to destroy the roots of hundreds of young fruit-trees in the course of a few days and nights, and will cut roots of grown trees of the most valued kinds, such as apple, pear, peach, plum, etc. They differ greatly in their size and also in their colors, according to age, but not in the sexes. The young are usually gray, the old of a dark chestnut, glossy and shining brown, very difficult to represent in a drawing. The opinion commonly received and entertained, that these Pouched Rats fill their pouches with the earth of their burrows, and empty them when at the entrance, is, I think, quite erroneous; about a dozen which were shot in the act of raising their mounds, and killed at the very mouth of their burrows, had no earth in any of these sacs; the fore feet, teeth, nose, and the anterior portion of the head were found covered with
