3^4 The Conclufion. 
the roots may the more readily make vlgo- . 
rous fhoots. And the greater proportion the 
furface of the roots bears to the furface of 
the plants above ground, fo much the greater

and confequently the plants will be the more 
vigorous, and better able to weather it out, 
againft unkindly feafons, than thofe plants 
whofe roots have made much fhorter fhoots. 
Herein therefore confifts the great care 
and skill of the Husbandman, to adapt

the very ftiff and ftrong ground, to the 
loofe light earths, may be wrought to the
