“Way down in the Sunny South,” began Old Mother Nature, “lives a member of the Rat family who, though not nearly so bad as Robber, is none too good and so isn't thought well of at all. He is Little Robber the Cotton Rat, and though small for a Rat, being only a trifle larger than Striped Chipmunk, looks the little savage that he is. He has short legs and is rather thick-bodied, and appears much like an overgrown Meadow Mouse with a long tail. The latter is not bare like Robber's, but the hair on it is very short and thin. In color he is yellowish-brown and whitish underneath. His fur is longer and coarser than that of other native Rats. “He lives in old fields, along ditches and hedges, and in similar places where there is plenty of cover in which he can hide from his enemies. He burrows in the ground and usually has his nest of dry grass there, though often in summer it is the surface of the ground. He does not live in and around the homes of men, like the Brown Rat, but he causes a great deal of damage by stealing grain in the shock. He eats all kinds of grain, many seeds, and meat when he can get it. He is very destructive to eggs and young of ground-nesting birds. He has a bad temper and will fight savagely. Mr. and Mrs. Cotton Rat raise several large families in a year. Foxes, Owls and Hawks are their chief enemies. “But there are other members of the Rat family far more interesting and quite worth knowing. One of these is Trader the Wood Rat, in some parts of the Far West called the Pack Rat. Among the mountains he is called the Mountain Rat. Wherever found, his habits are much the same and make him one of the most interesting of all the little people who wear fur. “Next to Jerry Muskrat he is the largest native Rat, that is, of the Rats which belong in this country. He is about two thirds as big as Robber the Brown Rat, but though he is of the same general shape, so that you would know at once that he is related to Robber, he is in all other ways wholly unlike that outcast. His fur is thick and soft, almost as soft as that of a Squirrel. His fairly long tail is covered with hair. Indeed, some members of his branch of the family have tails almost as bushy as a Squirrel's. His coat is soft gray and a yellowish-brown above, and underneath pure white or light buff. His feet are white. He has rounded ears and big black eyes with none of the ugliness in them that you always see in the eyes of Robber. And he has long whiskers and plenty of them.” “But why is he called Trader?” asked Rabbit a bit impatiently.
