size and the ridge is in the centre, is perhaps 

 to be preferred, as it is cheaper to build and 

 costs less for repairs. On a private place the 

 advantages of the even span are still greater, 

 because of the better adaptation of such a 

 house to a variety of uses. Thus, if the 

 owner is tired of growing roses, or has had no 

 success, the house is well adapted for some 

 other plant. 



Houses may be either of wood, or of wood 

 and iron combined (which is to be preferred). 

 This is sometimes referred to as iron or steel 

 frame, with a wood veneer to act as a cushion 

 for the glass. The iron house costs more, 

 naturally, but it lasts longer. It costs less for 

 repairs and admits more light, because its 

 framework is more slender and casts smaller 

 shadows. A house suitable for roses, even 

 span, 25 x 50 feet, six-foot sides, iron frame, 

 can be erected for about $2,200 without 

 masonry work, but covering cost of erection, 

 cement walks, iron frame benches with tile 

 bottom and glazed with 16 x 24-inch double 

 thick glass; also boiler and an adequate 

 system of four-inch cast iron pipes to main- 

 tain a temperature of 55 to 6o° in zero 

 weather and a cellar about ten feet wide
