aSource: Landsberg, Resources in America's Future,p. 884 Table A 16-20
and p. 889, Table A 16-15 served as basis of computation.
^Decrease in recoverable potential i960 as compared to 1929 is due to
decreased percentage going to railroads and ferrous castings, both of which have high
recovery rates, and to increases in percentage of steel and iron going to consumer
durables, containers, and ordnance, all of which have relatively low recovery rates.
