that reafon, the hedge had been formerly made to feparate them. 

 He pulled down the divifion, and, having laid them open, fet his 

 men to work on trenching them fix inches deep. The earth they 

 dug out of one trench in one field, he made them carry inftantly tp 

 another trench in the other field, in v/heel-barrows ; by this means 

 interchangeably mingling the gj-avi'I whh the clay, and the c/ay v.'ith 



the gravel. When this was done, he had it piow'd all over with 



a deep cutting plow, and has fow'd it every feafon fince with the 

 richell: srrains. The efFedt of this is, that he has not now a finer 



o ^ ^ / 



or more mellow piece of ground in his eftate. The very nature of 

 the land is altered, and there remains no vifible difference between 

 the two divifions, but the whole is converted into a good hazel- 

 rnauld, and produces a plump round corn, and as plentiful harvefls 

 as any foil in the kingdom. 



. The practice of the North-Riding of Yorkfliire, as related by 

 Dr. Lifter, Phil. TrajjfaSt. No. 225. fliews to how great advantage 

 clay is made ufe of there, as a manure. The clay is of a blueifh 

 colour, not fandy at all, but very ponderous. Thej/ dry it about 

 Midfummer, on the declivity of a hill, and lay 100 loads on an 

 acre of ground of a light fandy foil. They obferve, that for three 

 or four years it continues yet in clods upon the land ; and that the 

 firft year, the land fo manured bears rank ill-colour'd and broad- 

 grain'd barley, but afterwards a plump round corn like wheat. This 

 clay manuring will, by certain experience, laft above forty years in 

 the ground, and then it muft be clayed again. This fandy gi'ound, 

 unlefs clayed, will bear nothing but rye, whatever other manure 

 they ufe. 



Clay becomes a much better manure when mixed with lime, 

 than perhaps either of them are fingly. The lime corredts the bad 

 qualities of the clay, by rendering it more friable. 



Sea-oiofe, that is, the fettling of the tides - on fhores and level 

 places, between low and high-water mark, is a manure of incom- 

 parable excellence for many forts of lands ; but is, on others, to be 

 avoided, as a certain bane to whatever part 'tis mixed with. Loofe 

 fandy foils are peculiarly benefited by it. 



The cleaning of ponds and ditches becomes likewife here an 



excellent manure, confifting of the putrified animal and vegetable 



bodies mixed with the rich earth depofited there by rains, &c.
