174 FRUIT CULTURE UNDER GLASS. 



very much when it got a footing when the fruit were 

 setting. The trees should be dry the evening of fumi- 

 gation, and the tobacco should never be allowed to 

 burst into flame. The fumigation should not take 

 place when the trees are in bloom. 



Brown-Scale. I never had to deal with this insect 

 on peach-trees but once. The trees were syringed, 

 after they dropped their leaves, with water at 145; 

 and though the wood was coated with the insect, I 

 never saw more of it after the syringing. 



Thrips. This is a troublesome enemy to peaches 

 when it attacks them. It cannot be said that the 

 peach is subject to thrips ; but when plants infested 

 with them are placed in peach-houses which never 

 should be, but often is, done they spread rapidly on 

 the peach-foliage. Fumigation with tobacco, on which 

 some Cayenne pepper has been dusted, for a few suc- 

 cessive nights, destroys it. Engine the trees freely 

 after the fumigations to wash the insects and the 

 smell away. When the fruit are gathered, thrips can 

 be conquered by syringing two or three times with 

 tobacco -liquor, made by boiling at the rate of 3 oz. 

 of tobacco to a gallon of water. This should be 

 applied late in the evening, and the house kept close 

 for the night, so that the liquor may hang longer about 

 the foliage. 



DISEASES. 



The peach and nectarine are singularly free from 

 disease under glass in a good border, unless it be 

 mildew at times on some varieties. They are rarely 

 attacked with those diseases, such as curl and canker, 

 which are so troublesome on the open walls. Gum- 

 ming occasionally causes the death of a branch, and
