22 THE FORCING GARDEN. 
get both sun and air and moisture as they require it. 
Then the ‘ protector’ will form the desideratum for 
regulating the superfluous moisture during the winter, 
and possesses the advantage that it can be removed 
when the spring comes, so that the roots can get all 
the benefits arising from the full play of all three 
elements. Here then can be seen the difference 
between planting vines inside the house and _ pre- 
venting the roots getting outside by walls. I have 
known several failures of young vineries caused solely 
through this, and where they do not immediately fail, 
it is by reason of a great deal of labour in watering 
and artificial manure, or else failure would prove in- 
evitable. Those who intend planting vineries for 
forcing houses should plant them inside the houses, or 
rather, let the stems be inside of the front wall and the 
roots outside. This is easily done by small arches 
turned in the front wall under the surface of the bed 
outside. 
WINTER PRUNING THE VINE. 
The manner of pruning the vine depends chiefly 
upon the constitution of the plant. Some prune on 
the long-spur and some upon the short-spur, whilst 
others do so on the long-rod plan, and each of these 
may be equally good. The long-rod pruning can only 
be adopted when the vines are very strong, and it 
is known that this method can be safely employed 
annually without deterioration, or ultimately causing 
a failure of the vines. 
Either of the two former methods may be adopted 
annually, and some experienced gardeners always 
prune on the short-spur and get good crops while
