A corporation formed "to encourage immigration" may advertise;1 a railroad may establish a relief fund for its employees, to insure them against accidents and relieve itself from liability therefor;2 a corporation may defend its employee in a libel suit, where the paper was published in the usual course of business ;3 a bridge company may acquire land for the bridge and its approaches ;4 and a land company may employ a surveyor.5 A mutual insurance company, if not forbidden by statute, may write ordinary insurance.6 On the other hand, a boom company,7 or a corporation formed to improve the navigation of a stream,8 cannot handle or drive logs. A corporation formed for "manufacturing and selling heating and ventilating apparatus " cannot act as a broker of bonds;9 one formed to make insulated cables cannot contract to lay an electric conduit, taking risk of liability for damages;10 and a corporation formed for the purpose of "discussing arbitrating and settling all matters pertaining to the prosperity and promotion of the jobbing plumber's supply business," cannot engage in notifying creditors of delinquencies of debtors.11 Since a bank cannot conduct a manufacturing business, a mortgage, in which the bank undertakes to carry on such business is invalid.12
