98 Home Produce , Imports , Consumption , and 
agree almost absolutely with the annually adopted estimates for 
the same periods. For reasons already explained, however, 
when considering the results in Table I., the amounts calculated 
as available per head, from home and foreign sources together, 
are pretty certainly too low for the first five years of the last 
eight, and too high for the last three years. But, as will be 
seen in the bottom lines of the Table, the amount calculated as 
available per head per annum over the last eight years, that is, 
taking the five years and the three years together, is almost 
identical with, but very slightly in excess of, the annually 
adopted estimate for the period ; the average amount calculated 
as available being 5’66 bushels, and the estimate for the period 
annually adopted as forecast being 5 - 65 bushels. Lastly, the 
average consumption per head per annum over the forty years 
is 5 - 50 bushels, reckoned from the amounts available from home 
produce and imports together, and it is absolutely the same 
taking the average of the annually adopted estimates of require- 
ment per head over the same period. 
Such, then, is the accordance of the estimate of the con- 
sumption per head per annum of the population, founded on 
the amounts of wheat available from home and foreign sources, 
with the annually adopted estimates of the requirement j^r 
head. It is to be remembered that these estimates of the past 
are on the assumption of 60§ lb. per bushel for the doubtless 
somewhat drier foreign wheat, and of 61 lb. per bushel for the 
produce of the home crop. 
Effects of the Application to our previous Records 
and Estimates of the recently adopted Standards 
or Corrections. 
We have now to consider the differences which the changes 
in the weight per bushel of wheat, and in the relation of flour 
to wheat, which have been recently adopted, and also the cor- 
rections in the number of the population which have been 
referred to, would make in our results over the last forty years, 
if these various alterations were adopted throughout in the 
records and estimates of the past, as it is proposed they shall be 
in those of the future. 
Appendix-Table II. (facing p. 132) gives, in precisely the 
same form as in Appendix-Table I. (p. 132), the results for the 
forty years as to the estimated home produce, the amount of it 
available for consumption, the imports, the total available supply, 
the population, and the amounts available per head per anjium ; 
but with the home produce, both per acre and aggregate, and the
