The trade could obviously be carried out much more efficiently from there. Nevertheless, there were changes underway in the Chesapeake in the years from 1750 to 1775. The corps of indigenous traders was growing in both Virginia and Maryland. Some of them were not satisfied with the limited and highly competitive trade to the West Indies and sought entry to the vaster trade to Britain. Many were able to do so through the "cargo system" that flourished in the decade preceding the Revolution. Rich merchants in London, acting as factors (or agents on commission) for these smaller houses in the Chesapeake would buy "cargoes" of assorted goods for them from London middlemen on one year's credit and ship those goods out with the understanding that remittances would be made in tobacco or bills of exchange before the year's credit was up.

That those towns were not larger says something about the scale and nature of their operations. Much more innovative in these years was the growth of Norfolk and Baltimore from mere hamlets to loWll^uf abuut cix thousand inhabitants and active commercial centers—larger than anything else in the Chesapeake.

It produced a limited amount of tobacco of no very great repute and abundant forest products (pitch, tar, and lumber) plus some Indian corn, pork, and beef suit- able for the West Indies. With these endowments, Norfolk came to specialize in the West Indian trade. Because ot the volume ot
