Among the above ships is one called the Hancock and Adams, Capt.-. with a cargo of wheat and other produce of that country.

The Sampson, Capt. Farquhar, from London, which sailed from Poole in August last, for America, is safe arrived at Philadelphia, after being out 18 weeks.1

Letters by yesterday's Irish mail say, that a vessel, arrived at Bflfast from Bourdeaux, brings advice, that three ships belonging to the Provincials were lying in that port when she sailed ー two of them had delivered cargoes of tobacco, and the other flour, and they were then taking on board goods, but could not tell of what kind.
