46 OF THE CULTIVATION SECT.'IV. 



the roots of plants may not be impeded in the queft 

 of food ; fweet, that the food may be wholefome; and 

 rich, that there may be no defect of nutriment. 



Trenching the vacant ground in a garden, fc does good 

 to all foils in the autumn and zvinter feafons, and that 

 in proportion to its ilrength being indifpenfibly fiecef- 

 fary for clays to feparate and ameliorate the parts : The 

 light foils may do by being only rough dug, which is a 

 method that flronger foils will be alfo benefited by. 

 The foil would be ftill farther improved, byre-trench- 

 ing, or rough-digging, once or twice more in the 

 winter, if the opportunity offers, particularly if ftrong 

 or ftubborn. Let the ridges lie E. and W. except the 

 ground be a flope, when they may be in the direction 

 •that does. 



When manure is applied, the ground is not to be 

 glutted with dung; for a little at a time, well-rotted, 

 is fufficient, fo that it comes often enough, as opportu- 

 nity, and the nature of the cropping may dictate. It 

 is indeed a fort of rule with gardeners, that ground 

 fhould be dunged every fecond year ; but circum- 

 ilancesmay make more orlefs of it neceflary, and rules 

 fhould never be indifcriminately applied. If dung is 

 pretty well reduced (as it were to" earth) much lefs will 

 do, and let it not be buried too deep ; but if it is other- 

 wife, lay it low, to be dug upwards another time, when 

 it is more confumed. 



It is an excellent way of manuring,: efpecially where 

 the fuperficial foil is much exhaufted, to fpread over 

 rotten dung, late in autumn, in the winter, or early in 

 fpring, and fo let it remain, till the ground is wanted, 

 before it is dug in ; which fhould however be {lightly 

 dug before the manure is put on, or forked in a little 

 afterwards. This method is particularly to be re- 

 commended where crops of onions, leeks, and fuch 

 fuperficial rooting plants are to be. 



Dung ufed in great quantities, and lying in lumps, 

 breeds worms, grubs, and infecls, and makes plants 



grow
