Enclosures must have been numerous in some counties; and there is a very good comparison between " champion (open fields) country and several," which Blith afterwards transcribed into his Improver Improved.
The works of Gervase Markham, Leonard Mascall, Gabriel Plattes and other authors of the first half of the 17th century may be passed over, the best part of them being preserved by Blith and Hartlib, who are referred to below.
Sir Richard Weston must have cultivated turnips before this; for Blith says that Sir Richard affirmed to himself that he fed his swine with them.
Blith speaks of an instrument which ploughed, sowed and harrowed at the same time; and the setting of corn was then a subject of much discussion.
Blith was a zealous advocate of drainage and holds that drains to be efficient must be laid 3 or 4 ft.
This writer seems to differ a good deal from Blith about the advantage of interchanging tillage and pasture.
