42 THE FORCING GARDEN. 



5s. per foot run, that is, at half the advertised prices. 

 No top coping of glass is required ; in fact, such things 

 are useless, and I may say they are positively detri- 

 mental on account of the dryness they cause to the 

 border about the trees and the want of ventilation at 

 the top. It is essentially necessary to obviate any 

 close confinement at the top for wall-Peaches, especially 

 from the time the trees are in flower. Those who 

 recommend the close glazed top coping lights are no 

 gardeners. 



These sashes require nothing more than a board ven- 

 tilator at the top, made to open and shut ad libitum by 

 cords fixed on the outside and running through a pulley 

 fixed in the wall, with the cord passing through the 

 run at the top so as to come to the outside in front of 

 the lights. Then the ventilators can be opened and 

 shut without opening the sashes, and the bottom being 

 always open, a free circulation of air is secured at all 

 times a thing of immense importance in all Peach 

 and Plum growing. The runs are of 1-inch yellow 

 deal for the bottom, with the top cap fixed on iron 

 wall-brackets as is shown in fig. 14. The sides may 

 be of three-quarter stuff, the inner sides of the bottom 

 run being made a fixture, merely nailed on to the 

 bottom ; but the outer side of it must be made to open 

 at distances of 4 feet, to allow of the lights being 

 taken out when required. These openings must be 

 hinged on the bottom and held in position by a couple 

 of staples and a hook. The top run may be a complete 

 fixture. 



If the ends of the sashes and the runs are made 

 quite smooth no rollers will be required, as a little 

 grease rubbed now and then in the bottom run will
