Horace Gray, Allen v. St. Louis National Bank…
“ The notes and checks which passed between the factors and the bank were but forms to carry out the main purpose of the transaction between them, and did not change its nature or effect.By the common law, a factor or agent for sale has no power to pledge, whether the owner has intrusted him with the possession of the goods themselves, or with the symbol of them, as by consigning them to him by a bill of lading in which he is consignee or indorsee. ”
