Note 225 — CHAP. XVI. Of Ridges.

Since the Printing of my Essay, I find, upon Trial, that these narrow Ridges are as effectual as any for carrying the Water off from my clayey Hill; and that they be made much less horizontal than broad Ridges, whereby their Furrows are the more easily turned upwards against the Declivity.

I have not tried any narrower Ridge than that of Six Feet upon this Hill: But I have had full Experience of Five-feet and of Four-feet Ridges upon other Land; and find that all Sizes of these narrow Ridges are very advantageous, even where the Crop is to be sown upon the Level; for fewer Furrows are necessary for the Tilling of an Acre, when ’tis kept in such Ridges, than in broad Lands; and after wet Weather the Ridges will be fit to be plowed much sooner than level Ground.
