In the past, narrow houses from ten to twelve feet 

 in width (Fig. 5J2) hare been most used, but those of 

 recent construction are twenty feet and even wider. 

 Among the requirements for a violet house are (1) ven- 

 tilating arrangements that will furnish an abundance of 

 fresh air. On this account, ventilators are necessary in 

 each of the side walls of the house, as well as a row at 

 the ridge. It will be desirable to have the houses stand 

 a little apart to secure this, as well as to prevent the 

 lodging of the snow between the houses. (2) The 

 houses should be so glazed as to avoid drip. For this 

 reason a rather steep roof is desirable; the sash bars 

 should be provided with drip grooves and the glazing 

 should be carefully done. Use 14x14 or 16x16 inch 

 glass, butted without putty, and held in place with a 

 wooden cap. Take pains to lay the panes with the curve 

 up and with the thick edge at the bottom. If carefully 

 laid there will be little drip, although there will be 

 rather more than when the glass is lapped and laid in 

 putty, (3) Use wide, solid beds and have a walk along 

 each wall where it will occupy room of little value to 

 the crop. Thus for a house twenty-two feet wide (Pig. 

 23) we should have two beds each seven feet wide, and 

 three walks, the center one being two feet and six inches, 

 and the outer ones one foot and nine inches wide. If 

 they are given proper attention in a house of this kind, 

 the plants will do much better, and will be far less 

 likely to be attacked by disease, than when grown in 

 dugouts and other houses with heavy rafters, and covered 

 with hotbed sashes that cause a large amount of drip. 



Most of the narrow (ten or twelve foot) houses that 

 have been used for the violet have had two side beds and 

 a center walk, but rather better results will be obtained 

 with a bed in the center of the house seven or seven and 

 one-half feet wide, and a walk along either wall of the 

 house (Fig. 24).
