4& more expeditious method of computation to allow for interaction, 
and all other complications, was employed in the over-all Summary. It 
will be noted in the above example that the sum of the losses totals 
$50,000 which is 50 percent of the potential return of %190,000 ( that 
is, $50,000 + $30,000 $ #15,000 + $5,000). 50 percent of the original 
1,000 acres is 500 acres, the acreage equivalent of the combined losses 
with allowance for interaction. This agrees with the above more de- 
tailed analysis. 
The inclusion in this report of creps with different yields, and of 
losses incurred in storage, distribution, and feeding, in addition to 
those during production, introduces further complications in the intere 
pretation of the acreage-equivalent figures. However, the principles 
and the type of interpretation used in the sbove illustration are 
applicable to mary elerents in the picture. 
Extending this interpretation to the totals in this report, if no 
losses had been incurred, the actual returns from 1942—51 erons at 
eurrent prices conld apparently have been obtained from 120 million 
fewer acres than were in fact. used bv American farmers. The sums of 
the acreage equivalents in the tzbles considerebly exceed that fieure. 
While correct individually, they are rot properly additive, since 
losses interact. in several ways and the individual totals cannot 
allew for such interaction. 
Consolidated Values 
Te sum of the farm values of a1] individuel farm crops (Tables l- 
11) and the annual production of livesteck and poultry and their 
products (Tables 20-28) exceeds the gross return from farm products 
sold and consumed directly in ferm households, because many farm 
erons are used for snimal feeds, and the farmer’s cash income to 
that extent comes from livestock products instead of from crops. 
In the Summary, over-all base figures are used that make allowance 
for this factor. The adjusted arnual averages for 192=51 are as 
follows:

of products consumed directly in farm households:
