n 160 Perspectives in American History ^hese diree ports take it for granted that their trade was. the hands of their own merchants on whose account (i.e., with whose capital and at whose risk) both exports and imports were jnade.

How did all those new houses in New York and Philadelphia get started between the 1720*5 and the 1760*5? Finally, there is the mat- ter of auctions. In the years after 1815 one of the characteristic in- stitutions of British-American trade was the import auction, par- ticularly at New York. British manufacturers who had surplus stocks or needed cash in a hurry bypassed the export merchants and sent their goods directly to New York to be auctioned on arrival, usually for cash. It is clear, however, from the monographic litera- ture on the colonial period that similar auctions were being com- plained of in New York and Philadelphia in the 1760*5 and 1770*5. But we are told nothing of the persons who sent such goods for auction—though we get tantalizing hints of direct contact with Manchester.71 Then too we know all too little about the internal history of the businesses in these places. We have been told where the capital tor their ships came from, but not the capital for the firms themselves. These are some ot the problems that will have to be solved betore we can understand fully the inner dynamics of the mercantile communities in those port towns. 70.
