i Revised prices weighted by census production by States. 
- Weighted by preliminary production by States. 
s Average of monthly prices weighted by usual rate of marketing. 
Farm prices generally were higher than census values, 
nual weighted averages of monthly farm prices were higher than 
the December 1 prices, partly because December was a month in 
which prices generally were lower than the average for the season 
and partly because census production weights were not available 
for weighting the monthly prices of that year. This is shown by 
the lower December 1 prices resulting when the new census pro- 
duction weights were used. The much lower census value of pota- 
toes per bushel may be due in part to the fact that the April price 
of potatoes was much lower than the November price or the Decem- 
ber price, and April was the month when the census was taken. 
Some of the difficulties which have been mentioned above, such as 
the fact that the price of the quantity sold was higher than that 
of the portion of the crop not sold, may also have had an effect. 
COMPARISONS OF VALUE PER UNIT OF CROP PRODUCTION 
It is obvious that the price for any one month would differ con- 
siderably from a crop-year average of monthly prices weighted 
by the rate of marketing. Table 26 shows the percentage differences 
between December 1 prices and the crop-year average of monthly 
prices weighted by relative monthly marketings. As would be 
expected, the December 1 price is more often below the annual 
average than above. In only 3 cases were the December 1 prices 
of crops which are harvested late in the season, such as corn, buck- 
wheat, potatoes, sweet potatoes, clover seed, and beans, higher than 
the annual averages, whereas in 76 cases the annual averages were 
the higher. This might be expected in as much as farm prices in 
the later months of smaller marketings should in the long run be 
enough higher than the early season prices to compensate for 
storage costs and shrinkage losses.
