A corporation may act as agent, within the scope of its charter powers,14 but the power must be expressly granted or be implied as necessary to properly carry out express powers so granted. It is quite common now for corporations to be organized whose main purpose shall be to act for others, in a representative capacity, as agent. Where the authority to act as agent, is not expressly given, it may be implied, where it is necessary to carry the main purposes of the corporation.
