across one end of the house. Such a house 

 should have two lines of ventilators, at the 

 ridge. If the house is to be built with a pos- 

 sibility of growing other plants at any time, 

 side ventilators may be provided also, to be 

 used when necessary. Certain fluctuating 

 charges on account of freight, cartage, ex- 

 penses of workmen, excavating and grading 

 would have to be added to the figure quoted. 

 The cost of these would vary according to 

 local conditions and might reach a total of 

 $700 more, and masonry work would consume 

 perhaps $1,000. Thus a sum of about $4,000 

 should be figured upon as necessary to build 

 a really first-class house of the most approved 

 modern type for roses, including American 

 Beauty, which requires more head-room and 

 more heat than the other varieties commonly 

 grown under glass. A house of the same 

 size built of sash bar, all cypress wood, and 

 without cement walks would cost about one- 

 third less. An iron frame house 20 x 50 feet 

 would cost about $1,900 for the superstructure 

 and $900 for masonry, including the cellar. 

 The height of the sides modifies the cost of 

 the house very materially, but necessitates a 

 greater expenditure to maintain the required
