THE FRUIT-TREE AND SHRUB PRUKER. 



in detail as is necessary) all that is really requisite on 

 the management of the Peach on walls out of doors. 

 They should, however, be frequently syringed during 

 the development of the buds before the flower expands; 

 but never syringe them while in full flower. It is a 

 good plan in fruit-growing to preserve the pollen of 

 the flower as dry as possible. To do this, hexagon 

 fine cotton netting or coarse gauze let down over the 

 trees at night is a good preventive against the night 

 damps during its development ; but these screens should 

 be removed by nine o'clock in the morning at the least, 

 on sunny da}\s. The syringing may be carried on 

 frequently after the fruit is set, and it should be done 

 early in the morning during the months of May and 

 June, before the sun rises upon the trees. I prefer 

 the morning for syringing at this period, because, if 



done in the even- 

 ing, the chilly cold 

 nights give an ad- 

 ditional check to the 

 sap ; and I have no 

 doubt but that this 

 is the cause of the 

 crippled state mostly 

 attendant upon the 

 young growth of wall 

 Peach-trees in the 

 spring. The crippled 

 state of the buds 

 must certainly arise 

 from the effects of the 

 cold nights. This 

 suggests a balancing 

 of the day and night 

 air by some means ; 

 and I kno wof nothin » 

 better adapted to 

 this than the hexa-
