Progress In Ocean Travel. In 1840 the Cunard steamship Britannia, Brit-annia, built of wood, propelled by paddle pad-dle wheels, maintained a sea speed of about 8V knots.- Her steam pressure was 12 pounds per inch. She was 207 feet long, about 2,000 tons displacement, displace-ment, her engines developed about 750-horse power, and her coal consumption con-sumption was about, 40 tons a day, or about five pounds of coal per indicated horse power per day. She carried a full spread of sail. In sixty years speed has been increased from 84 knots to twenty-three knots; the time on the voyage has been reduced to fcfbout one-third of what it was in 1840.
