so by
breaking the earth oftner then any other Share, causeth the land to
yeeld a good and plentifull mould, and also keepe it from binding or
choaking the seede when it is cast into it.

Now for the Coulture, it differeth from the former Coulture both in
breadth and thicknesse, but especially in compasse: for whereas the
former Coulture for the blacke clay, was made straight, narrow, and
thicke, this must be compassed like an halfe bent bow: it must be
broader then three fingers, and thinner then halfe an inche, according
to this Figure.

{Illustration: The Coulture.}

Now when these Irons, the Shelboard, and other implements are fixed vnto
the Plough, you shall perceiue that the Plough will carry the proportion
of this Figure following.

{Illustration: The Plough for the gray Clay.}

Hauing thus shewed you the substance, difference, and contraries of
these two Ploughs, which belong to these two seuerall clayes, the blacke
and gray, you shall vnderstand that there is no clay-ground whatsoeuer,
which is without other mixture, but one of these Ploughs will
sufficiently serue to eare and order it: for all clayes are of one of
these tempers.

{SN: The vse and handling.}
Now for the vse and manner of handling or holding this Plough, it
differeth nothing in particular obseruation from the vse and handling
of the Plough formerly described, more then in the largenesse and
smalnesse of the furrowes: for as before I said, whereas the blacke clay
must be raised with a great furrow, and a broad stitch, this gray clay
must be raised with a small furrow, and a narrow stitch: and although
this plough haue nothing but a left hand Hale, yet considering the
Plough-staffe, vpon which the Plow-man resteth his right hand, it is all
one as if he had a right. And indeede, to make your knowledge the more
perfect, you shall know that these gray clayes are generally in their
owne natures so wet, tough, and slimy, and doe so clogge, cleaue, and
choake vp the Plough, that hee which holds it shall haue enough to doe
with his right hand onely to clense and keepe the Plough from choaking,
insomuch that if there were another Hale, yet the Plow-man should haue
no leasure to hold it.

{SN: Of the draught or Teame.}
Now for the Draught or Teame which should draw this Plough, they ought
in all points, as well in strength as tryuing to be the same with those
before shewed for the vse of the blacke clay: as namely, eyther Oxen or
Horse, or Hors
