selves, an event which occurs in a wonderfully short time, they leave the maternal home, and 
dig separate burrows. 
The strangest part of the Hamster’s character is its dull, unreasoning ferocity, which is. . 
utterly incapable of comprehending danger, and causes the animal to attack any kind of oppo- 
nent, whether animate or not. An irritated Hamster will fly upon a dog, a man, or a horse, 
without the least hesitation. If a cart were to crush it, it would try to bite the wheel; if a 
stone were to roll over it, it would turn upon the lifeless stone; threaten it with a stick, and it 
fastens upon the senseless weapon with malign fury ; and when opposed by a bar of iron nearly 
red hot, it has been known to grasp the burning metal in its teeth, and to retain its hold in spite 
of the pain which it must have suffered. This combative disposition leads it to fight desper- 
ately with its own species, caring nothing 
for sex or age; and it has actually hap- 
pened that when a pair of these animals. 
have been placed together in a cage, the 
male has been killed and partly eaten by 
his disconsolate widow. 
The food of this animal is chiefly vege- 
table, but is varied by animal diet, such 
as worms, insects, mice, small birds, lizards, 
frogs, and other such vermin. It is a noc- 
turnal animal, and achieves its robberies. 
under cover of the darkness of night. It 
can hardly be termed a true hibernating: 
animal, as it is quite lively for a consider- 
able portion of the winter, feeding on its. 
ample stores for nearly two months, and be- 
coming very fat by the combined influence 
of inactivity and good feeding. Through 
a portion of the winter it becomes torpid, 
but awakes early in the spring, ready to 
renew its depredations in the fields. During 
the spring and summer months its food con- 
sists chiefly of leaves and various herbage. 
AT uncertain and distant intervals of 
THE LEMMING.—Myodes lemmus. time, many of the northern parts of Europe, 
such as Lapland, Norway, and Sweden, 
are subjected to a strange invasion. Hundreds of little dark, mouse-like animals sweep over 
the land, like clouds of locusts suddenly changed into quadrupeds, coming from some unknown 
home, and going no one knows whither. These creatures are the LEMMrNGs, and their sudden 
appearances are so entirely mysterious, that the Norwegians look upon them as having been 
rained from the clouds upon the earth. 
Driven onwards by some overpowering instinct, these vast hordes travel in a straight line, 
permitting nothing but a smooth perpendicular wall or rock to turn them from their course. 
If they should happen to meet with any living being, they immediately attack, knowing no 
fear, but only urged by undiscriminating rage. Any river or lake they swim without hesita- 
tion, and rather seem to enjoy the water than to fear it. If astack or a corn-rick should 
stand in their way, they settle the matter by eating their way through it, and will not be 
turned from their direct course even by fire. The country over which they pass is utterly 
devastated by them, and it is said that cattle will not touch the grass on which a Lemming 
has trodden. 
These migrating hosts are accompanied by clouds of predaceous birds, and by many pre- 
daceous quadrupeds, who find a continual feast spread for them as long as the Lemmings 
are on their pilgrimage. While they are crossing the rivers or lakes, the fish come 1n for their
