another.“A boat of h novel and useful description is about to be introduced on the Pennsylvania Canal. Its object is to obviate the transhipment ofgoods which is unavoidably required from the Canal to the Portage Railway over the Alleghany, and again from the Railway to the Canal. The Pittsburg Gazette says that the boat is so constructed, that, 011 its arrival at the Railway, it can be divided into two pieces, iv.doii regaining the Canal may be speedily reunited. Two boats of this kind li 4ve already passed from the eastern to the western division of the Canal, one of which had about eighteen tons freight. Its performance, both on the Canal and Railway is said to have been perfectly satisfactory.”T 1. ! lt;■ ^ 1 . n • . . m A a A - _ 1 _ lt;• 1
