and to the placing of the plants, or the feed, moft properly 

 in the ground, a few obfervations here may be particularly 

 neceflary. 



The land upon which peas or tares may be cultivated to 

 advantage, does not require to poflefs fo deep a ftaple, as 

 that appropriated to the culture of beans ; the feed of which, 

 in mod foils (be their texture what it mayj fhould never be 

 depofited at a lefs depth than five or fix inches below the 

 fettled furface of the ground. The neceflity for placing the 

 bean thus deep, will appear very obvious to any one, who 

 will take the trouble to infpedl the root of the bean, when 

 the plant has attained to its full growth, and its feed to its 

 compleat maturity : it will then appear evident, that from 

 the point where the feed was depofited in the ground^ it fends 

 downwards a long flender tap root, and upwards a thick 

 ftrong one. along this upper divifion of the root, lateral 

 fibres are detached from the feed, to the furface of the 

 ground, and are evidently deflined to colledl and convey 

 nourilhment to the plant. The long lap root which defcends 

 perpendicularly, and to a great depth from the point where 

 the feed was placed in the ground, being perfe6lly clear of 

 laterals, will not be fuppofed to contribute, but in a fmall 

 degree, to the growth and fubfiftence of the plant. Hence 

 the necefiity of placing the bean to a proper depth in the 

 ground, that the plant may not be deprived of its proper 

 organs for receiving and conveying from the earth, that por- 

 tion of nourilhment which the bean requires ; but which, 

 as well as in the cafe of peas, or tares, will not be found 

 equal to that conftantly demanded and dravvn from the land 

 by turnips, cabbages, and the white ftrav/ crops. 



To exemplify this truth, it is only neceflfary to attend to 



the efFe6l the root of trees produce along the hedge rows 



upon the lafl: mentioned crops, but whofe effeils are fcarcely 



to be difcerned in thofe of peas, tares, and beans.
