The industry was in a promising and healthy condition, and so continued, until in 1720 the London shipwrights informed the Lords of Trade that the New England shipyards had drawn away so many men “that there were not enough left to carry on the work.” They therefore prayed that colonial built ships be excluded from all trade except with Great Britain and her colonies, and that the colonists be forbidden to build ships above a certain size. The Lords of Trade, though fine crusty old protectionists, were unable to see their way to granting any such prayer as this, and so ship-building continued to flourish in America. In the year 1769, the colonists along the whole Atlantic coast launched 389 vessels, of which 113 were square-riggers. It should not, however, be imagined that these vessels were formidable in size. The whole 389 had an aggregate register of 20,001 tons, an average of slightly over 50 tons each. Of these vessels 137, of 8013 tons, were built in Massachusetts; 45, of 2452 tons in New Hampshire; 50, of 1542 tons, in Connecticut; 19, of 955 tons, in New York; 22, of 1469 tons, in Pennsylvania. It is probable that few of them exceeded 100 tons register, and that none was over 200 tons register. With the advent of the Revolutionary War, the rivalry on the sea between the older and the younger country took a more serious turn. Centuries before clipper ships were ever thought of, England had claimed, through her repeated and victorious naval wars against Spain, Holland, France, and lesser nations, the proud title of Mistress of the Seas, but in the Revolutionary War with her American colonies and the War of 1812 with the United States, her battleships and fleets of merchantmen were sorely harassed by the swift, light-built, and heavily-armed American frigates and privateers. While it cannot be said that the naval power of England upon the ocean was seriously impaired, yet the speed of the American vessels and the skill and gallantry with which they were fought and handled, made it apparent that the young giant of the West might some day claim the sceptre of the sea as his own.
