THE CANADA POUCHED RAT. 505 



The burrow was probably sunk lower wherever it crossed a path, because the sense of 

 hearing in this animal is so extremely acute, that it would be much annoyed by the continual 

 sound of human footsteps immediately over its head. 



Although it spends the greater part of its existence beneath the earth, it is frequently 

 seen above the surface of the ground, as it resorts to the open air for the purpose of basking 

 in the sun, or procuring leaves which have been brightened and vivified by the rays of the 

 sun, as a change from the roots on which it chiefly depends for subsistence. When it revisits 

 the regions of upper day, it emerges from the earth in some hitherto unbroken spot, pushing 

 the soil upwards and causing a kind of miniature earthquake before it makes its appearance. 

 Presently the head and shoulders of the animal emerge from the lump of earth, and shaking 

 the loose mould from its fur, it draws itself entirely out of its burrow. It then runs forward 

 for a yard or two, searching for food, nibbling off the green blades with its teeth, and stowing 

 them into its cheek -pouches with the aid of its fore-paws. When it has filled the pouches, it 

 runs back to the hole through which it had issued, and vanishes immediately from sight. 



Should it be alarmed while out of its tunnel, it plunges precipitately into its stronghold, 

 and drives an entirely new burrow in another direction, not venturing to entrust itself to that 

 through which it had passed before it was alarmed. 



The long and sharp incisor teeth are formidable weapons, and can be used with great 

 effect upon an adversary. It is a sufficiently savage creature, and when captured or annoyed, 

 bites fiercely in every direction, and squeals with rage. In captivity it is always employing 

 these teeth upon every object that it can reach, and has even been detected in the act 

 of endeavoring to cut its way through the wooden planks of the room in which it was 

 placed. Two of these animals once contrived to get into a pair of boots belonging to their 

 owner, and not choosing to take the trouble of returning by the same aperture through which 

 they had entered, they cut a large hole in ihe toes, and so made their exit. They seemed to 

 have a special liking for leather, as they afterwards gnawed to pieces the leathern straps 

 which were dangling from a portmanteau that lay in the same room. 



On the surface of the ground the Canada Pouched Rat is rather slow and clumsy in its 

 movements, as its legs are short and ill-fitted for such locomotion. So short indeed are its 

 limbs, that if it be laid on its back, it has great difficulty in regaining its feet, but flounders 

 about in almost total helplessness until it can seize a blade of grass, a twig, or similar object, 

 by means of which it can draw itself into its normal attitude. In its tunnel, however, it 

 proceeds with considerable activity, going faster than a man can walk, and being capable of 

 running backwards or forwards with equal speed and ease. 



The nest of the Mulo is not placed in one of the ordinary tunnels, but in a burrow dug 

 specially for the purpose. It is about eight inches in diameter, globular in shape, and is 

 made of dried herbage externally, and softly lined with hair plucked from the body of the 

 female, and other appropriate substances. Prom the nest radiate a number of small galleries, 

 which are again connected with smaller branch passages, and seem to conduct the animal to 

 its feeding-grounds. It was formerly imagined that the Mulo was in the habit of filling its 

 pouches with the excavated earth, and of emptying them at the mouth of burrows. This 

 assertion is now disputed, for it is clearly ascertained that the creature only uses its cheek- 

 pouches for the conveyance of its food. A little earth may perchance be imbedded together 

 with the nuts and leaves, but the mistake has evidently arisen from the conduct of the natives, 

 who, when they procure a skin of the Mulo, are accustomed to stuff the pouches with dry 

 earth, for the purpose of preserving them in their distended form. 



The animal is found in many parts of Northern America, and has a very wide range. 



The Bay Bamboo Rat is one representative of the genus Rhizomys, of which there 

 are several species. 



This animal is a native of Nepal, Malacca, and China, and is very injurious to the bam- 

 boos, on the roots of which it feeds. In size it equals a rather small rabbit, and in color it is 

 of a uniform ruddy brown, slightly paler on the throat and abdomen. The long incisor teeth 

 are faced with bright red enamel, which gives them a rather conspicuous appearance ; the tail
