VENTILATION. 29 



the time the peach trees have come into flower 

 until they have "set" or formed into fruit a drier 

 and more airy atmosphere should be observed, 

 and from the time the peaches begin to colour 

 that is, begin to ripen until they have been 

 gathered, a free circulation of air should be ad- 

 mitted day and night. However, during the period 

 of growth, from the time that the leaves are being 

 developed in houses in which peaches are expected 

 to be ripe at the end of April or early in May 

 until the fruits begin to colour, draughts must be 

 guarded against, as a current of cold air coming 

 in contact with the young leaves and fruit might 

 produce undesirable results in the way of mildew 

 and "curl." During these stages of growth, the 

 front ventilators should be used with great care 

 and judgment when the wind is cold; in fact, in 

 these circumstances, all the fresh air that is required 

 can be admitted through the roof ventilators. If 

 a strip of tiffany be secured inside the peachery 

 to the plates and end mullions immediately in front 

 of the front ventilators, it will admit as much fresh 

 air to the interior of the house as is needful for 

 the welfare of the trees and crop being thus early 

 forced, and at the same time obviate the risk of 

 a current of cold air finding its way to the trees.
