86 FRUIT CULTURE UNDER GLASS. 



season be very dry, the outside portion of the border 

 will be the better for a slight mulching of half-decayed 

 litter, which wiU prevent the necessity for watering 

 much. The inside border, after the roots have penetrated 

 into it, will also be the better of a similar mulching, but 

 only to a slight extent. Avoid applying water that has 

 not stood in the vinery cisterns for some time to get 

 warmed a little. 



I am not favourable to syringing much, but it does 

 more good and less harm to young fruitless vines than 

 under other circumstances, and it is a preventive of 

 red-spider. As the season advances, and the sun gets 

 powerful, leave air on to a small extent all night after 

 syringing the foHage, and it should be increased as early 

 as 6 A.M., in order to get the foliage diy before the sun 

 acts powerfully on the glass, otherwise the foliage may 

 suffer under the clear glass now used. 



The night temperature during the summer months 

 may range from 70° to 75°, when the necessity for fire- 

 heat is at its minimum. With the increase of light, air, 

 and heat, atmospheric moisture should be increased, and 

 vice versd ; but by all means avoid at any time a close, 

 stagnant, damp atmosphere. As soon as the wood be- 

 gins to ripen, admit more air, causing a circulation 

 among the foliage by opening the front lights more 

 freely, and gradually decrease the amount of moisture. 

 Examine the foliage, and if there be any red-spider on 

 it, give a few vigorous syringings, and take every means 

 of keeping the foliage in a healthy state, tiU the vines 

 have matured it, and throw it off in a natural way. 

 When the wood gets dark brown and well solidified, 

 open all the ventilators to their full extent, except in 

 times of high winds, which might injure the leaves, it
