But thereafter the size of ships--both packet and clippers--steadily and rapidly increased.
Glancing down the long table of ships and their records prepared for the United States census, we find such notations as these.
Ship "Flying Cloud," built 1851; tonnage 1782; 374 miles in one day; from New York to San Francisco in 89 days 18 hours; in one day she made 433-1/2 miles, but reducing this to exactly 24 hours, she made 427-1/2 miles.
Ship "Comet," built 1851; tonnage 1836; beautiful model and good ship; made 332 knots in 24 hours, and 1512 knots in 120 consecutive hours.
"Sovereign of the Seas," built 1852; tonnage 2421; ran 6,245 miles in 22 days; 436 miles in one day; for four days her average was 398 miles.
"Lightning," built 1854; tonnage 2084; ran 436 miles in 24 hours, drawing 22 feet; from England to Calcutta with troops, in 87 days, beating other sailing vessels by from 16 to 40 days; from Boston to Liverpool in 13 days 20 hours.
"James Baines," built 1854, tonnage 2515; from Boston to Liverpool in 12 days 6 hours.
Three of these ships came from the historic yards of Donald McKay, at New York, one of the most famous of American ship-builders.

The figures show the steady gain in size and speed that characterized the work of American ship-builders in those days.

Then the United States was in truth a maritime nation.

Every boy knew the sizes and records of the great ships, and each magnificent clipper had its eager partisans.

Foreign trade was active.
