 others adhere to walls, gates or palings. 



Fresh leaves should frequently be put in, and 

 the box or case covered with a piece of fine can- 

 vas, or gauze, to admit the fresh air. 



At the same time that the trees are cleared of

 terpillars should be carefully looked for and picked 

 off. You will observe, that they shelter them- 

 selves at the end of the shoots, in the flowers, 

 and at the bottom of the footstalks of the flowers. 

 There are two or three sorts that infest fruit-trees,

 trees with a mixture of urine, soap-suds, and

 thriving state, and bear very fine fruit. 



In 1795 I used the above method with a great 

 many dwarf Apple-trees ; and the effect was so 

 visible next season, that all who saw them took 

 notice of the great difference between them and 

 the remaining trees, which we had left to nature j
