190 Account of a Crab Apple Orchard. 



■ • - ■ ' ■ ' ' ■'■>' — 



of the most famed apples of Herefordshire, in England, 

 I recur to my old doctrine, that the earth delights in 

 changes of products. The o/^ trees give evident proofs 

 of this position. Natural trees endure longer than those 

 engrafted. 



I think Mr. Wynkoop's trees are all too near each 

 other. Mine stand in squares of forty feet. I have 

 heretofore, Vol. I. pages 211, and seq. given an ac- 

 count of my orchards. It will be seen, page 217 of that 

 volume, that I had suggested to Mr. Coxe, the belief 

 of many orchardists, that clover was in itself injurious. 

 He thought otherwise ; but in Mr. Wynkoop's an- 

 swer to query 2d, he mentions a fact relative to the 

 bad effects resulting from clover ; which may, indeed, 

 apply to any other plant, likely to invite vermin. I 

 know several crab orchards; some whereof are plough- 

 ed round the trees, some not stirred ; and yet they are 

 generally more productive, than those of the kinds 

 commonly planted. I think Mr. Wynkoop's success, 

 is a conclusive argument that his practice is the most 

 favourable, on every account ; at least so far as re- 

 spects this species of tree ; than which no fruit-tree 

 can pay better for the pains bestowed on it. 



Your obedient servant, 



Richard Peters.
