These are all found in Africa. They are curious little creatures with extremely long hind feet, by means of which they leap along just as if they were tiny kangaroos. So swift are they, that it is very difficult for the eye to follow their movements. And as they disappear into their burrows at the slightest alarm and do not come out again for some little time, few people ever have a chance of watching their habits. The snouts of these shrews are so very long that the little animals are often known as elephant-shrews. TREE-SHREWS This is a group so called because they spend almost the whole of their lives in the trees. In some ways they are not unlike tiny squirrels, being nearly as active in their movements, and sitting up on their hind quarters to feed, while the food is held in their fore paws. They are found in various parts of Southern Asia. They soon become very tame, actually entering houses, and climbing up on the table while the occupants are sitting at meals. They will even drink tea and coffee out of the cups! And if they are encouraged they make themselves quite at home, and will drive away any other tree-shrews which may venture into the house. The largest animal of this group is the tupaia, which lives in Borneo and Sumatra. But the most curious is the pen-tailed tree-shrew, which has a double fringe of long hairs at the end of its tail, arranged just like the barbs of a feather, so that its tail looks very much like a quill pen. The rest of the tail, which is very long, is covered with square scales; and while the tail itself is black, the fringe of hairs is white, so that the appearance of the animal is very odd. It is found in Sarawak, and also in some of the smaller islands of the Malay Archipelago. THE DESMAN This animal may be described as a kind of mixture of the elephant-shrew and the water-shrew; for it has an extremely long and flexible snout, and it spends almost its whole life in the water. Its feet are very well adapted for swimming, the toes being joined together by a web-like membrane like those of the duck and the swan, so that they form most exquisite paddles. And the animal is so fond of the water that, although it lives in a burrow in the bank of a stream, it always makes the entrance below the surface. This is a very good plan in one way, for if the little animal is chased by one of its enemies, it can easily take refuge in its long, winding tunnel, which twists about so curiously, and has so many side passages, that the pursuer is almost sure to be baffled. But in another way it is a bad plan, for as the burrow has no entrance except the one under water, it never gets properly ventilated, the only connection with the outer air being some chance cranny in the ground. And in winter-time, when deep snow has covered up this cranny, while the surface of the stream is frozen to a depth of several inches, the poor little desman can get no fresh air at all, and often dies in its own burrow from suffocation.
