What put me upon this Method was an Observation of two Lands (or Ridges) drill’d with _Turneps_ in Rows, a Foot asunder, and very even in them; the Ground, at both Ends, and one Side, was hard and unplow’d; the _Turneps_ not being ho’d, were very poor, small, and yellow, except the Three outside Rows, _B_, _C_, _D_, which stood next to the Land (or Ridge) _E_, which Land being plow’d and harrow’d, at the time the Land _A_ ought to have been ho’d, gave a dark flourishing Colour to these three Rows; and the _Turneps_ in the Row _D_, which stood farthest off from the new-plow’d Land _E_, received so much Benefit from it, as to grow twice as big as any of the more distant Rows. The Row _C_, being a Foot nearer to the new-plow’d Land, became twice as large as those in _D_; but the Row _B_, which was next to the Land _E_, grew much larger yet[2]. [2] A like Observation to this on the Land E, has been made in several Turnep Fields of divers Farmers, where Lands adjoining to the Turneps have been well tilled; all the Turneps of the contiguous Lands that were within three or four Feet, or more, of the newly pulveriz’d Earth, received as great, or greater increase, in the Manner as my Rows B C D did; and what is yet a greater Proof of the Length of Roots, and of the Benefit of deep Hoing, all these Turneps have been well Hand-ho’d; which is a good Reason why the Benefit of the deep Pulveration should be perceivable at a greater Distance from it than mine, because my Turneps, not being hoed at all, had not Strength to send out their Roots through so many Feet of unpulveriz’d Earth, as these can through their Earth pulveriz’d by the Hoe, tho’ but shallowly. This Observation, as ’tis related to me (I being unable to go far enough to see it myself) sufficiently demonstrates the mighty Difference there is between Hand-hoing and Horse-hoing. _F_ Plate 6. is a Piece of hard whole Ground, of about two Perch in Length, and about two or three Feet broad, lying betwixt those two Lands, which had not been plow’d that Year; ’twas remarkable, that during the Length of this interjacent hard Ground, the Rows _B_, _C_, _D_, were as small and yellow as any in the Land. The _Turneps_ in the Row _D_, about three Feet distant from the Land _E_, receiving a double Increase, proves they had as much Nourishment from the Land _E_, as from the Land _A_, wherein they stood; which Nourishment was brought by less than half the Number of _Roots_ of each of these _Turneps_. In their own Land they must have extended a Yard all round, else they could not have reach’d the Land _E_, wherein ’tis probable these few Roots went more than another Yard, to give each _Turnep_ as much Increase as all the Roots had done in their own Land.
