Price : American Port Towns 139 distinguish between limited and general merchants, merchants who dealt with only one geographic area or commodity group and merchants who dealt with all areas and in all goods significant for the economies of their home regions. In America this distinction separated the smaller merchants who dealt only with the West Indies from their bigger confreres who traded to Europe. This hierarchy of traders created a hierarchy of trading towns. Primary traders tended to scatter across the countryside where they would be accessible to their agricultural customers. Secondary traders, however, tended to congregate along main trading routes in places convenient for their customers, the primary traders, and with easy access to the major ports. Except for a few spots such as Lancaster, Pennsylvania, the seats of these secondary traders were almost entirely in riverine and coastal ports. While any hamlet or country crossroad or public warehouse in the Chesapeake might do for the site of the "store" of a primary trader, secondary traders tended to be found in towns and townlets of 1,500-4,000 popula- tion, which as ports and county seats often attracted more traffic than their modest size would suggest. Merchants properly so called tended to congregate in coastal or river ports which could handle ocean-going vessels, had easy access to the full variety of goods needed for their export trades, and were convenient to markets for their imported goods.28 Even so, not all the ports where mercantile activity took place\ perform^ the siar1""* fi-inr^rmc (i) Sr.m? -n».rf. mere shipping points, Is were loaded and nnlnarleH. irhilr nrhrn ivrif1 f cessinc; centers where goods received some manufacture in transit.
