EXPERIMENTS WITH TURNIPS. 143 



rows. The turnips in the row (d) which stood 

 furthrst off from the newly-ploughed land (e) re- 

 ceived so much benefit from it as to grow twice as 

 large as any of the more distant rows ; the row (c), 

 being a foot nearer, became twice as large as those 

 in (d); but the row (h) which was next to the land 

 {e) became larger still. 



" A like observation to this on the land (e) has 

 been made in the turnip-fields of several farmers, 

 where lands adjoining the turnips have been well 

 tilled, and all the turnips of the contiguous lands, 

 which were within three or four feet, received great 

 benefit, in the same manner as did the rows (b c d). 

 This is a still stronger proof of the length of roots 

 and the benefits of deep hoeing than the former 

 illustration, as all these turnips had been well hand- 

 hoed, which is a good reason why the benefits of 

 the deep pulverization should be perceivable at a 

 greater distance from it than in mine, because, as 

 mine were not hoed at all, they had not strength to 

 send out their roots through so many feet of un- 

 pulverized earth, as these through the soil which 

 had been pulverized by the hoe, although but 

 shallowly. 



" (/) is a piece of hard ground of about two 

 perches in length, and about two or three feet broad, 

 lying betwixt those two lands, which had not been 

 ploughed that year. It was remarkable that during 

 the length of this interjacent hard ground the
