The gopher may be found east of the Rocky Mountains and to the west of the Mississippi river, between the thirty-fourth and fifty-second parallel of north latitude. It leads an underground life, digging tunnels in various directions. Tunnels, of old standing, says Brehm, are packed hard and firm from constant use. Lateral passages branch off at intervals. The main chamber is situated under the roots of a tree at a depth of about four and one-half feet; the entrance tunnel is sunk down to it with a spiral direction. This chamber is large, is lined with soft grass, and serves for a nesting and sleeping-place. The nest in which the young, numbering from five to seven, are born about the beginning of April, is lined with the hair of the mother. It is surrounded with circular passages from which the tunnels radiate. Gesner found that a passage leads from the nest to a larger hole, the storeroom, which is usually filled with roots, potatoes, nuts, and seeds. When throwing up the earth the gopher exposes itself to view as little as possible and immediately after accomplishing its purpose plunges back into its hole. According to Audubon it appears above ground to bask in the sun. We have seen it sit at the entrance to its den with an air of bold indifference to the approach of danger and then suddenly vanish under ground. Its acute sense of hearing and great power of scent protect it from surprises. Audubon kept several gophers in captivity for months, feeding them on potatoes. Their appetites were voracious, but they would drink neither water nor milk. They made incessant efforts to regain their liberty by gnawing through boxes and doors. They constantly dragged clothing and other similar objects together, utilizing them as bedding, first gnawing them to pieces. One of them, straying into a boot, instead of turning back, simply gnawed its way through the tip. The habit of gnawing was unendurable and Audubon incontinently got rid of them. The gopher is very destructive to valuable trees and plants, for which reason man is its most dangerous enemy, the only other foes it has to fear being water and snakes. This pretty little rodent is often found in populous neighborhoods. A few years ago the writer saw one rush into a hole under the root of a large osage orange bush in Woodlawn, Chicago. Curiosity led him to watch for the reappearance of the animal, which soon put its head cautiously above the entrance and eyed the intruder with as much interest as a weasel will often show under like circumstances. For several weeks the gopher was visible in the morning hours. We pointed it out to several persons, each of whom declared it to be a ground squirrel. There is a great difference in these small animals, but they are frequently confounded. The name of gopher is applied in some American localities to various other rodents. HANS AND MIZI. DR.
