 most other apple trees. Some kinds viz. the Holland 

 pippin and American nonpareils, did not suffer at 

 all the Jersey greenings, were among those which 

 suffered most. The comparative inferiority of stahle 

 dung as a manure for apple trees, was very visible in 

 this plantation. 



In 1816, this orchard has grown very finely : the 

 trees are large, and have borne abundantly for the first 

 time ; which has arisen from the great vigour of their 

 growth, retarding the fruitfulness of the trees, until 

 they had attained to a considerable size. 



EXPERIMENT NO. 8. 



In the end of October 1806, the same day with 

 the preceding experiment, 1 planted at about fifty feet 

 apart, 180 apple trees, on a lot ploughed the preceding 

 spring, but not sowed, adjoining to Nos. 2 and 3. The 

 holes were dug, and the ground manured after plant- 

 ing with stable dung, in the same manner as No. 7 

 the soil much lighter: in the Spring of 1807, the field 

 was manured with ashes and planted in corn forty 

 of the trees had been brought from a distant nursery, 

 of which the soil was so stiff, that many of the roots 

 were much injured, and all of them shortened by dig-
