vieUls a greater rent than If the same were in but few." These 

 are facts which experience confirms and whic!i admit of easy 

 explication ; they are facts, which every farmer, every land- 

 lord, should be convinced of, and nowhere do they stand more 

 in need of the conviction than in many parts of Suffolk and 

 Norfolk. Chap. 4. — Sect. 1. is occupied with a description of 

 the various parls of a plough, the different species of this im- 

 plement, |the qualifications necessary for a good plouglmian, 

 and the times and modes of ploughing suited to different soils. 

 Sect. 2. Of sowing contains plain directions for the practice 

 as performed in Agriculture, which I shall not stop to no- 

 tice. — His admonition frequently to obtain seed from another 

 soil, if possible from rfnc poorer, and of a more northern lati- 

 tude, is now a trite recommendation, — that it is beneficial it 

 is certain, and the explication easy. The greatest suscepti- 

 bility of germination is of course desirable ; the quicker a 

 seed vegetates, the sooner it is out of the reach of accidental 

 injury or destruction ; and it may be taken as an axiom in the 

 general accurate, that under natural circumstances, the plant 

 from the latest vegetating seed of a given species is the weak- 

 est; — now seed raised in a cold climate germinates mu<h more 

 rapidly in. a warmer one, than when again sown in a soil of thii 

 same latitude ; Adanson states that seed raised at Paris, has 

 its period of germination accelerated from one to three days 

 in different individuals (Families des Plantes, v. i. p. 84.) 

 Again plants growing in a poor medium, acquire a habit of en- 

 larging their roots for tlie sake of increasing their surfaces of 

 introsusception ; plants from seed raised from plants growing on 

 a poor soil, I have observed to possess much more abun- 

 dant roots, than similar ones from seed raised in richer 

 soils. From these causes arise the benefit of obtaining seed 

 from a northern poor soil — and we would make one observa- 

 tion, which has often arisen to us when reflecting on the apti- 

 tude which plants have of acquiring habits, that it is an argu- 

 ment for their being endowed with sensation, which we could
