Progress is being made toward establishing standards in ship con- 
struction, equipment, and operation by the American Merchant Ma- 
rine Standards Committee in cooperation with the Department of 
Commerce. (This is discussed further under “Progress in Simplified 
Practice,” p. 24 of the Commerce Yearbook.) 
Great progress has been made in the output of vessels fitted with 
internal-combustion engines. The gross tonnage of such vessels, 
launched throughout the world during 1925, was 843,600 compared 
with 501,800 in 1924. The total for 1925 was equal to about 65 per 
cent of the world’s output of steam vessels, compared with 29.5 per 
cent in 1924. At the beginning of 1926, moreover, the tonnage of 
motor ships under construction almost equaled the tonnage of steam- 
ships being built, whereas a year earlier, it was only 60 per cent. 
The gross tonnage of all motor ships of 100 gross tons and over was 
1,180,000 on June 30, 1922; 1,321,000 on June 30, 1923; 1,655,000 
on June 30, 1924; and 2,714,000 on June 30, 1925, according to 
Lloyd’s Register. The United Kingdom continues to lead in owner-
