This Magazine is rapidly becoming popular as the exponentof American ship-building, and it is our intention, with the en-lightened co-operation of the ship builders in the United States,together with their brethren of British North America, to pre-sent to the commercial world a mirror of the ship-yard, as wellas a daguerreotype of the ship; and to this end, our friends haveonly to sit down and help themselves.
