In another connection the Conference Board also shows 
that there has been practically very little increase in 
mechanization of industry and labor productivity in Great 
Britain for the 17 years ending 1924.1 While the returns 
for the British 1924 Census have not been completed, an 
analysis of eight leading industries showed that, on the 
basis of 1913 prices, the output per worker in 1907 was 
£316 or approximately $1,540 as against £357 or $1,740 
in 1924, an increase of only $200 or 13 per cent. per 
worker. During practically the same period, the output per 
worker for the leading industries of the United States 
advanced 35 per cent., or, as the Board states: “Eight 
selected major manufacturing industries in the United 
States which use an average of 174 as much horsepower 
per wage-earner employed as do the same industries 
in Great Britain, turn out, largely as a result of this 
greater use of power, from 214 to 3 times as much pro-
