ROSES UNDER GLASS. 149 



Whether it be a specially built Rose house or a pit 

 frame, Roses can be grown to flower from February 

 to June, and provided ordinary care is taken, the 

 smallest grower can be as successful as the grower 

 with a large house to attend to. First, let us con- 

 sider the Rose house, its construction and its heating; 

 then let us deal with the cultivation under glass of the 

 Queen of Flowers herself. 



When we consider that beautiful Roses can be 

 obtained in winter through the use of a pit frame, or 

 the smallest, if carefully heated, greenhouse, we feel 

 that it is well worth while experimenting with a few 

 trees and we pot up a dozen or two dozen for the 

 purpose, knowing that even if they fail we have an 

 asset in trees that can be planted out later in our 

 gardens. Make a start, good reader, grow a few 

 trees and then if you are a true lover of the queen of 

 flowers you will grow your fifties or your hundreds. 

 Glass houses to-day are so cheap that no garden should 

 be without one, and a good gardener will nearly 

 always make it a paying proposition. 



A good Rose-house is a good house for most 

 flowers and fruit, and its construction is quite ordi- 

 nary. Much depends upon the site that you have to 

 allot. For light and ventilation, a house should stand 

 on its own, but for the conserving of heat and general 

 utility a three-quarter span against your garden wall 

 is hard to beat. It is far better than the lean-to, for 

 its gives the additional light through the back roof. 

 Messrs. Boulton and Paul, Ltd., of Norwich, have for 

 a hundred years made a study of glass houses for 

 every site imaginable, and a letter will always secure 

 an answer, giving advice and cost of house to meet a 

 client's requirements. In the case of a garden wall 

 to be used, the height and condition should be given ; 

 also the width of land available, for invariably a path 

 that cannot easily be moved runs parallel to the wall. 

 A good width for a three-quarter span is either lo, 12, 

 or 16 feet; the back wall should be about 7 feet high
