the all steel construction as described, owing to the fact 

 that where flat iron rafter houses are used there is a certain 

 amount of weakness between the iron rafters. In the construc- 

 tion of this house, iron frame beds with cypress sides and tile 

 bottoms were used. The heating consisted of hot water, the 

 Rose house being warmed to a temperature of 55 to 60. The 

 all steel makes an exceptionally durable structure and, as there 

 is practically no wood inside, it can be easily kept free of vermin 

 and fungous growth and is, therefore, the most desirable char- 

 acter of house for Rose growing. The height of the sides can 

 be regulated according to the character of Roses to be grown.
