“These do not,” answered the naturalist; “at least it is supposed they do not. Many that have been shot and opened proved to have nothing in their stomachs but insects and beetles—such as these we see upon the prairie. I think it is probable the owls make an occasional meal of the horned frogs and lizards; though I have no proof of this farther than that birds of this kind usually prey upon such reptiles.”
“But how live the rattle-snakes?” inquired François; “what do they feed upon?”
“Ah!” replied Lucien, “that is the puzzle of naturalists. Some assert that they are the tyrants of the community, and devour the old marmots. This can hardly be, as these snakes are not large enough to swallow them, in my opinion. Certain it is, however, that they prey occasionally upon the young, as many of them have been killed with young marmots in their belly?”
“Why, then,” rejoined François, “the snakes seem to have it all their own way. If they eat the young marmots, what is to hinder them from killing as many as they please? They can enter the burrows with as much ease as the marmots themselves!”
“That is true,” replied Lucien, “but not half so nimbly; and perhaps the latter can even escape them within. The rattle-snake is a very slow crawler; and, besides, only strikes his prey when coiled up. Perhaps, in these subterranean galleries, he is still less able to capture it; and the old marmots may, after all, have some mode of defending both themselves and their young from his venomous attacks. As yet very little is known of these creatures. The remote regions in which they are found place them beyond the observation of naturalists; and such of these, as have visited their towns, have been only allowed time to make a hurried examination of them. They are very shy; rarely letting you get within range of a gun. They are, therefore, seldom shot at. Moreover, it takes great trouble to capture them by digging—on account of the depth of their burrows—and as their skins are not very valuable, and their flesh but a bite at best, they are not often molested by the hunter.”
“But are they eatable?” inquired François.
“Yes,” answered Lucien; “the Indians are very fond of their flesh, and eat it whenever they can conveniently get it; but, indeed, they will do the same for almost every living creature.”
“What do marmots feed upon in winter, when there is no grass for them?” inquired François.
“They then lie torpid. They have nests in their subterranean chambers, and curious nests these are. They are constructed of grass and roots, are as round as a globe, and so firmly woven together, that one of them might be kicked over the prairie like a foot-ball. The nest is within, with a small hole leading into it, just large enough to admit your finger—for when the marmot goes inside, he closes all up, except this little hole, through which he gets all the air he requires. In these snug beds they lie asleep during the cold season, and at that time are rarely seen outside their burrows.”
