represented at c, in the section), then from these trellises the 

 Vines are trained along the back-wall, between d and / hori- 

 zontally, on a perpendicular trellis; those on the front are also 

 trained horizontally, between c, and g, and the young shoots 

 are not permitted to go higher than e, so that from e to b is 

 left entirely open for the free admission of sun and light to 

 the trellis and back wall.* By comparing the extent to train 

 on, with a house of much larger dimensions, say, for example, 

 one of fifty feet in length, fourteen feet in width, twelve feet 

 in height, with a front wall of five feet (two feet and a half of 

 which is generally glass), it will be seen that there is very 

 little less extent for training on, in these houses, than in one 

 of the above dimensions, when the plants are trained in the 

 common way. In the former there are eight hundred and 

 eighteen superficial feet, and in the latter eight hundred and 

 fifty, while the cubical contents of air to be heated in the 

 first, is three thousand five hundred and six feet, and in the 

 other five thousand nine hundred and fifty feet, making a 

 difference of no less than two thousand four hundred and 

 forty-four cubical feet, in favour of the narrow house, while 

 the difference in the extent for training on is only thirty-two 

 superficial feet. From this it is very evident that less fuel 



* The mode of training is further illustrated by a drawing of the interior of 

 the house, which is annexed to the section. The Vines not being : originally 

 intended for a house of this description (having been trained up under the glass 

 in the common way) I was under the necessity of using the wood produced for 

 that purpose, but I prefer having the branches horizontal, and always get plenty 

 for a supply from the shoots arising from near the bottom j I always stop those 

 that produce the fruit at a joint or two above the bunch, and select a shoot near 

 the bending (where they are in general strong) for my next year's supply, laying 

 it in a little longer.
