Of these, fifteen to be built in NewYork, by Poillon, Stack, and others; fifteen to [Page 733] be built at Mystic, Connecticut, by Mallory and others. The engines are to be built by Delamater, of New York. Dispatch to be used, as they are wanted *immediately, and are expected to be ready in from sixty to ninety days. [754]
