“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.
“Patience, Peter, patience. I'm coming to that,” chided Old Mother Nature. “He is Trader because his greatest delight is in trading. He is a born trader if ever there was one. He doesn't steal as other members of his family but trades. He puts something back in place of whatever he takes. It may be little sticks or chips or pebbles or anything else that is handy but it is something to replace what he has taken. You see, he is very honest. If Trader finds something belonging to some one else that he wants he takes it, but he tries to pay for it.
“Next to trading he delights in collecting. His home is a regular museum. He delights in anything bright and shiny. When he can get into the camps of men he will take anything he can move. But being honest, he tries to leave something in return. All sorts of queer things are found in his home--buckles cut from saddles, spoons, knives, forks, even money he has taken from the pockets of sleeping campers. Whenever any small object is missed from a camp, the first place visited in search of it is the home of Trader. In the mountains he sometimes makes piles of little pebbles just for the fun of collecting them.
