That the climate of England is changed within the last half century, it now generally admitted. Mr. Williams has lately attempted to account for it, by the great introduction of foreign trees and grasses, which, being natives of hotter climates, give out a far greater evaporation than our own indigenous vegetables. I have only seen an account of this gentleman's book, not the book itself. The fact is very curious, and the application highly ingenious. But it is manifest that this solution is not adequate to the phenomenon: for change of climate is equally complained of in other countries, where planting is not in fashion, and where no improvements in agriculture have been introduced. To those countries it is not applicable, neither will it explain the increased prevalence of west and south-west winds.
