XX. — On the Home Produce, Imports, Consumption, and Price 
of Wheat, over 28 {or 27) Harvest-Years, 1852-3 to 1879-80.

Ph.D., F.R.S., F.C.S. 
In our paper " On the Home Produce, Imports and Consump- 
tion of Wheat," published in this ' Journal' in 1868, we gave 
records and estimates on the subject for sixteen harvest-years, 
1852-3 to 1867-8 inclusive ; and in 1863, and each year since, 
an estimate for the then current year has been published in the 
' Times,' and elsewhere, soon after harvest. We propose, on the 
present occasion, to pass in review the estimates formerly given, 
and to complete the record from the commencement up to the 
present time ; namely, for twenty-eight (or twenty-seven) years, 
1852-3 to 1879-80 inclusive. In our former paper we gave the 
records and estimates for each division of the United Kingdom 
separately, and for the whole collectively ; but it is proposed 
now to confine the illustrations to the United Kingdom as a 
whole. 
The main elements of the question are the following : — 
1. The area under wheat. 
2. The average yield of wheat per acre. 
3. The aggregate home produce, and the amount of it available 
for consumption. 
4. The imports. 
5. The population. 
6. The average consumption of wheat per head of the popula- 
tion per annum. 
The data then at command, and the results arrived at, were 
fully considered in the paper above mentioned, and we must 
refer to it for detailed information on most of the points in 
question, but the main facts may be briefly summarised here.
