The fisheries, particularly whale and cod, were an important source of income, those of Massachusetts being estimated, in 1750, at £250,000 per year. Fishers' hamlets, with their great net-reels and drying stages, were strung along the shores. The men engaged in the traffic were hardy and bold, no weather deterring them from long voyages to Newfoundland and Labrador, while whale-fishers ventured into the Arctic seas. From their ranks were largely recruited the superb sailors who made the American navy famous in the two wars with England. Sidenote: Shipbuilding. A pinnace, called the "Virginia," was constructed by the Popham colonists in 1607,--the first ocean-going vessel built in New England. Shipbuilding was first undertaken at Plymouth in 1625, and in Massachusetts six years later (1631). By 1650 New England vessels were to be seen all along the coast, and carried the bulk of the export cargoes. Before 1724 English ship carpenters complained of American competition. In 1760 ships to the extent of twenty thousand tons a year were being turned out of American shipyards,--chiefly in New England; and most of them found a market in the mother-country. Sidenote: Commerce. Dried fish was the chief commodity carried out of New England, and was exported in American bottoms to Spain, Portugal, and the West Indies. Fish-oil and timber were also sent out of Maine and Massachusetts to foreign countries; hay, grain, and cattle were taken to New York, Philadelphia, and the West Indies. There was an active longshore coasting service by small craft, which ascended the rivers and gathered produce from the farmers; these they took to neighboring ports, and brought back other colonial products in exchange. Larger vessels went with miscellaneous cargoes to the West Indies, and returned with slaves and sugar. New Englanders manufactured rum from West India sugar and molasses, and exported the finished product. There are instances of New England ships taking rum to Africa, where it was exchanged for slaves; these slaves were then transported to the West Indies, to be bartered for sugar and molasses, which was carried home and converted into rum. It was a day when kegs of rum and wines were given to ministers at donation parties, and ministers themselves made brandy by the barrel for domestic use, and sold it to their parishioners. Wines were imported from Madeira and Malaga, and manufactured goods from England and the Continent. A very large and profitable business was done in the general carrying trade, which was developed by enterprising New England men in all the sister colonies. Boston alone employed, by the middle of the eighteenth century, about six hundred vessels in her foreign commerce, and a thousand in her fisheries and coast-trade.
