Transcriber's Notes:

Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed.

Simple typographical and spelling errors were corrected.

Provided anchor for unanchored footnote on p. 33.

In the table to the footnote to p. 119 the 1 6 for oats or rye should likely be in the same row.

On p. 122 either the total of £9,460,957 should be £9,360,957 or one of the summands is incorrect.
