To hide it from eyes would not be so important to him as to hide it from noses. Smelling was more to be feared than seeing ; to bury it would seem to the owner the way to best protect it. Such a habit would be of immense benefit to the possesser of it. Such habit could be easily formed, it seems to me. It is certain that different families of animals practise it and profit by it.

The squirrel family and their near relatives the gophers are noted for carrying away stores for future use, and our striped squirrels do the
