Willis Luther Moore, The new air world (1922)
“ Some idea of the vast interests floating on the Atlantic coast may be had when it is stated that 5628 trans-Atlantic steamers, with an aggregate of 10,076,148 tons, and 5842 sailing craft, aggregating 2,105,688 tons, entered and left ports on the Atlantic seaboard during a single year ten years ago, and the record is vastly greater now. The value of their cargoes is more than a billion and a half of dollars. Our coastwise traffic is enormous. Fifteen years ago more than seventeen thousand sailing vessels and four thousand steamers entered and left the ports between Maine and Florida. ”
