ordinarily used in greenhouse construc- 

 tion. The gutters are of the King pat- 

 tern, made of channel iron supported on 

 posts of 2-inch iron pipe. Each post 

 acts as a down spout and empties into a 

 vitrified tile drain, laid along the inside 

 of the wall. 



"Below the gutters, in the side walls, 

 is twenty-four inches of glass. 



"Ventilation is secured by two lines 

 of interrupted sash, operated by Foley 

 ventilating machines. 



* ' The walls below the side lights are 

 composed of concrete, but constructed 

 differently than those usually built. The 

 iron pipes supporting the gutters are set 

 into concrete piers 12x18 inches and ex- 

 tend well into the soil, to secure a firm 

 foundation. The walls themselves are 

 formed of large conereto. slabs, which are 

 five inches thick, reinforced with %-inch 

 iron rods, and fit in between the posts. 

 Their ends rest on the concrete piers and 

 are held in place by concrete pilasters 

 eight inches square, built about the posts. 

 The sill was anchored to this wall and 

 the side rafters put into place. 



' ' The benches are each 4x100 feet and 

 five inches deep, and are built of pecky 

 cypress supported on 1-inch iron pipes, 



' ' The walks between the benches are 

 twenty-eight inches wide and those be- 

 tween the benches and walls are twenty- 

 two inches wide. All walks are of ce- 

 ment. 



Service Bttildtn£. 



* ' The service building is a structure 

 26x100 feet, constructed of wood, with 

 jdaster finish on the outside. It is 

 situated on the north side of the green- 

 houses, with its longer axis parallel to 

 the longer axis of the greenhouses. A 

 space sixteen feet wide was left between 

 the service building and the greenhouses. 



"One-half of this building is large 



enough to accommodate three sixty horse- 

 power boilers. The concrete floor of this 

 room is about two feet below the floor 

 level of the greenhouses. 

 ' ' The other half of the building is de- 



voted to a large workroom, about twenty- 

 five feet square, a hallway, an oflSce 

 13x20 feet, a small laboratory, a small 

 room and a lavatory. The workroom con- 

 tains a reinforced concrete floor, making 

 it possible to scrub it out whenever 

 necessary. 



"Beneath this part of the building 

 is a cellar, divided into three rooms. 

 Tlirough the largest of these extend all 

 the steam, water and sewer pipes. This 

 makes an excellent room for storage. The 

 other two rooms, which^take up the other 

 half of the cellar "space, are used as cut 

 flower and cool storage rooms. 



Heating Plant. 



"The heating plant is somewhat dif- 

 ferent from that used in most places. At 

 the present time power is secured from a 

 sixty horse-power tubular boiler, the set- 

 ting of which was designed to reduce the 

 amount of smoke as mucii as possible. 

 Draught is secured by a 70-foot brick 

 stack, designed to carry 180 horse-power 

 if necessary. 



"The heating system was constructed 

 to be run either as a high or low pres- 

 sure system. From the top of the boiler 

 a 6-inch feed main drops down into the 

 cellar to the pressure regulator and its 

 accompanying by-pass. From here the 

 main continues and passes under the 

 cross house. At this place branches of 

 11/4,-inch pipe come off and, passing 

 through 6-inch tile, emerge in the green- 

 houses under the benches and by the side 

 walls. 



"Under the benches the 1^,4-inch pipe 

 divides into two l^/i-inch pipes, one ex- 

 tending down each side of the bench. 

 These pass down to the other end, cross 

 over, and come back on the opposite side. 

 There are also two wall coils, one of 

 which passes around the end to the door, 

 'ihis, then, gives four lines of pipe under
