"Any one having contractual capacity may be a bailee, but no persons, with the exception perhaps of inn keepers, common carriers, wharfingers, or warehousemen, can be compelled to be bailees, since a person has the same right to decline becoming a bailee as he has to decline becoming a purchaser.9

"It is not essential that the bailor should have an absolute title to the subject-matter of the bailment, it being sufficient if he is invested with such possessory interest in the subject matter as will entitle him to assert his interest against all the world except the rightful owner." 10
