OF THE PINE-APPLE.

so that late in the season its fault is generally that 

 of being too dry. 



It is observable, too, that the young, or succes- 

 sion Pine-plants, do not make half the progress in 

 violent hot weather, in the middle of summer, that 

 they do later in the season. 



In order to obviate the above inconveniences, 

 some persons cover their hot-houses in the middle 

 of the day, when the heat of the sun is violent, 

 with bass-mats fastened to a rope, which may be 

 moved up and down with great ease. But a bet- 

 ter mode, and which is frequently practised, is, to 

 cover the glasses with a large net, which admits 

 the air to pass freely, and at the same time breaks 

 the rays of the sun, and retards their force, espe- 

 cially if the meshes of the net be not large. 



But if Vines were judiciously trained up to 

 the rafters of the hot-house, there would be no 

 need of either of the last-mentioned coverings. 

 The Vines should be planted in the front of the 

 hot-house, and not more than one shoot trained to 

 each rafter, part of which should be cut down to 

 the bottom of the rafters every season, by which 

 means the roof of the hot-house may constantly be 

 kept thinly covered with young wood ; and, by hav- 

 ing only one shoot to each rafter, the Vine-leaves 

 will afford a kindly shade, and never incommode 

 the Pines ; for the leaves fall, and the Vines 

 are pruned at a season when the hot-house most 

 requires sun.
