-H FRUITS AND VEGETABLES UNDER GLASS 



belore the fires arc dispensed with. But with ail seeming eare and good judg- 

 ment mildew will at times appear. 



Location also plays an important part as the cause of this trouble. Grap- 

 eries along the sea coast as well as those located on low lying ground are much 

 more subject to mildew than are those situated farther inland. While Grapes 

 clear of mildew can be produced near the sea coast they require much closer 

 attention. The man who is interested in growing Grapes under glass will watch 

 for the first appearance of any unwelcome visitor. If mildew is allowed to spread 

 unchecked, even for two or three days, the damage will be great, but if preven- 

 tive measures are taken at once, giving a light dusting of sulphur to the 

 affected parts, it may check the spread. In a very severe case a little sulphur 

 may be burned. Procure a small iron pot and an oil lamp large enough to 

 heat this pot, then just burn a little sulphur in the bottom of it. This must 

 be done very carefully. When the air in the house begins to get too un- 

 pleasant to stay in it, remove the lamp or put it out; liave the house closed 

 down and keep it so closed for about an hour. 



SCALDING OF THE BERRIES 



Scalding of the berries is a serious trouble at certain stages, the most dan- 

 gerous one being at about the period of their stoning. Sometimes only a berry 

 or two may be affected, while at other times an entire bunch may be destroyed. 

 Some varieties are more subject to scalding than others; Gros Maroc will scald 

 in an early house, but not in a late one, and both Muscat of Alexandria and 

 Lady Downs Seedling will scald easily. This is caused more or less when the 

 temperature rises and the sun strikes the berries while there is moisture on them. 

 For these reasons the atmosphere should be watched carefully at the stoning 

 period of the fruit; particularly does this caution apply to those in the early 

 house. This scalding of the berries generally takes place in the morning. While 

 the thermometer may not read high the temperature between the foliage and 

 the glass may be quite different; for this reason the house should be aired suf- 

 ficiently to take the condensation off the berries before the hot sun strikes them. 



Rust is at times more or less troublesome. While it does not at first seem 

 to hurt the Grapes to a great extent, the berries affected swelling away and devel- 

 oping the same as do those not affected, yet it is eventually the cause of serious 

 disfigurement, as the marks can be plainly seen when they become ripe. Rust 

 usually appears shortly after the thinning. It is generally ascribed to careless- 

 ness in that operation; that is, because the fingers have come in contact with 

 the berries or, if the man engaged in the thinning is awkward at his work, allow- 

 ing his hair to come in contact with the bunch. As the berries are then very 

 tender, the skin is easily marred, but these marks will not show until they have 

 expanded somewhat. An experienced man will guard against any part of his 

 body or clothes coming in contact with the berries, but a novice will be apt to
