4. What proportion of the arable land above measured should you consider suitable to the production of wheat under general conditions such as are given in the text, say, a stable price of one dollar per bushel in London?

Answersquare miles.

5. To what extent, in your judgment, is wheat becoming the cash or surplus crop of a varied system of agriculture as distinct from the methods which prevail in the opening of new lands of cropping with wheat for a term of years?

What further remarks can you add which will enable me to elucidate this case, to complete the article and to convey a true impression of the facts to English readers?

Your assistance in this matter will be gratefully received.
Respectfully submitted,
Edward Atkinson.

To this circular I received twenty-four detailed replies, containing statistics mostly very complete; also many suggestive letters, in every case giving full support to the general views which I had submitted in the proof sheets. It has been impossible for me to give individual credit within the limits of a magazine article to the gentlemen who have so fully supplied the data. Space will only permit me to submit a digest of the more important facts in a table derived from these replies:
