tion has proven most durable, and 

 the best suited to our variable climate. 



The Greenhouse a Factory. 



The modern greenhouse has been 

 developed through constant effort to 

 obtain durability and light. These 

 may be considered the two most im- 

 portant requirements. The day of the 

 very cheap greenhouse has passed be- 

 cause both the owner of private green- 

 houses, and the florist, realize today 

 that the first cost is not so important 

 as the final cost. When we build pri- 

 vate greenhouses for pleasure and en- 

 joyment, what pleasure will we derive 

 from the houses if their ridges sink, 

 their roofs and sides become warped, 

 and the glass slides out of place? 

 From the florists' point of view, is not 

 the greenhouse but a factory, and is 

 it not as reasonable to build well a 

 flower factory as it is a factory for the 

 production of any other article of 

 commerce? Build well, and your 

 maintenance cost is low. Deprecia- 

 tion percentage is low. Equip your 

 factory or greeu house with proper 

 facilities, and the producing cost will 

 be low. 



We must have light if we have noth- 

 ing else. In general, plants grown in 

 the dark are not hardy. Light is re- 

 quired to develop firm resistant tis- 

 sue, and we are given as an instance 

 potatoes sprouted in a cellar. The 

 sprouts will wilt when exposed to nor- 

 mal conditions of light and heat. Be- 

 cause of our better understanding now 

 of the absolute necessity for light, the 

 greenhouse with small panes is a 

 thing of the past too. 



I stated that I would not attempt to 

 give the history of construction and 

 methods. I will only deal with the 

 best modern iron-frame greenhouses. 

 These must be divided into two 

 classes, — private and commercial 

 greenhouses. 



The Modern Private Greenhouse. 



The modern private iron frame 

 greenhouse is erected on walls of ma- 

 sonry, stone, brick, or concrete. 

 Heavy cast-iron sills are set in mor- 

 tar on top of the walls, and in large 

 buildings are anchored by heavy l)olts 

 which are built into the walls. Raf- 

 ters are made of one-half inch flat 

 iron of from three inches to five 

 inches in width. These rafters are 

 bolted to the sills, and are either bent, 

 welded or spliced at the eaves line to 

 give shape to the root. The rafters 

 are brought together at the ridge and 

 secured by means of ridge plates. 



Rafters are set on the sills eight feet 

 four inches apart, center to center, 

 and the space between two adjacent 

 rafters is called a section, so there 

 are three sections to 25 feet, and 12 

 sections to 100 feet. In other words, 

 these houses are built in multiples of 

 eight feet four inches. The rafters are 

 held parallel to each other by angle 

 iron purlins, which are placed length- 

 wise of the house, and are double lug- 

 ged and bolted to the rafters. 



Three Ways. 



At the eaves the house may be 

 built in any one of three ways. First, 

 is the galvanized angle-iron eaves 

 plates, which are much stronger and 

 much more durable than the cumber- 

 some old-time wooden plates, and 

 which cast very little shade. Also one 

 of the flanges of the angle eaves plate 

 is inside of the house and subject to 

 the heated interior. Hence, icicles do 

 not grow very well on these plates, 

 and the plate has been called the 

 "ice-clearing eaves plate." The angle- 

 iron plate is fitted with metal clasps 

 which receive the ends of the sash 

 bars. This plate when made with met- 

 al clasps as described, is protected by 

 letters patent. Angle-iron eaves plates 

 are more adaptable to commercial 

 houses than for houses on private 

 estates. 



The second method of arrangement 

 at the eaves is the sectional cast-iron 

 gutter, which is bolted to the rafters. 

 One side of the gutter (the inside), 

 is provided with a flange, to which 

 clasps are bolted to receive the sash 

 bars. The inner side of the gutter is 

 exposed to the inside temperature of 

 the greenhouse, so that icicles and 

 snow will not usually last very long 

 in such gutters as they will in the 

 old-time non-conductiong wooden gut- 

 ters. 



The third arrangement or detail is 

 the curved eave. In this case a com- 

 bined sill and gutter is used to cap the
