OUR EXPERIMENT STATION. 



A Paper Kead Before the Illinois State 

 Florists' Association by Trof. II. 

 li. Dorner. 

 . As a result of the appropriations of 

 two years ago the Agricultural Exper- 

 iment Station has undertaken to carry 

 out certain lines of work relating to 

 floriculture. In order to do this so 

 that all parts of the experiments are 

 under perfect control the erection of 

 some new greenhouses was necessary. 

 During the last summer two houses 

 and a service ouilding have been con- 

 structed. 



In erecting these the aim was to 

 build model commercial houses and 

 as a result the state possesses houses 

 second to none. The ground plan 

 chosen is one which allows of expan- 

 sion and in fact all parts of the plant 

 have been so designed that new 

 houses can be added without changing 

 or interfering with those already up. 

 The plans call for a range of houses 

 extending east and west from a corri- 

 dor or connecting house extending 

 north and south. The plans call for 

 detached houses with intervals of 14 

 feet between. The service building, 

 which also contains the heating plant, 

 connects with the corridor house on 

 the north. All houses can thus be 

 reached from the service building 

 without going outside. 



Greenhouses. 

 The two houses already erected 

 were designed to avoid shading as 

 much as possible and so are of the 

 very lightest construction possible, 

 commensurate with strength. Each 

 house is 105 feet long and 28 feet wide, 

 thus making it possible to have tour 

 100 feet benches, each 4 feet wide. 



All parts above the gutters are of 

 clear cypress with sash bars of the 

 type ordinarily used in greenhouse 

 construction. The gutters are of the 

 King pattern 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 24 

 inches of glass. Ventilation is secured 

 by two lines of interrupted sash oper- 

 ated 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 12 x 18 

 inches and extend well into the soil to 

 secure a firm foundation. The walls 

 themselves are formed of large con- 

 crete slabs, 5 inches thick reinforced 

 with 3-8 inch iron rods and At in be- 

 tween the posts. Their ends rest on 

 the concrete piers and are held in 

 place bv concrete pilasters 8 in. 

 square built about the posts. The sill 

 was anchored to this wall and the side 

 rafters put into place. 



The benches are each 100x4 feet 



and 5 inches deep and are built of 

 peclcy cypress supported on 1-inch iron 

 pipes. The walks between the benches 

 are 28 inches wide and those between 

 the benches and walls are 22 inches 

 wide. All walks are of cement. 



Service Building. 



The service building is a structure 

 100 feet long by 26 feet wide con- 

 structed of wood with plaster finish on 

 the outside. It is situated on the 

 north side of the greenhouses with its 

 longer axis parallel to the longer axis ■ 

 of the greenhouses. A space 16 feet 

 wide was left between the service 

 building and the greenhouses. 



One-half of this building is large 

 enougli to accommodate three 60 

 horse power boilers. The concrete 

 floor of this room is about two feet 

 below the floor level of the green- 

 houses. The other half of the build- 

 ing is devoted to a large work room 

 about 2.5 feet square, a hall way, an 

 office 13x20 feet, a small laboratory, 

 a small room and a lavatory. The 

 work room contains a reinforced con- 

 crete floor making it possible to scrub 

 it out whenever necessary. 



Beneath this part of the building is 

 a cellar divided into three rooms. 

 Through the largest of these extend all 

 the steam, water and sewer pipes. 

 This makes an excellent room for stor- 

 age. 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 GO-horse power tubular boiler, 

 the setting of which was designed to 

 reduce the amount of smoke as much 

 as possible. Draught is secured by a 

 70-foot brick stack designed to carry 

 ISO horee power if necessaiT. 



The heating system was constructed 

 to Ic 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 regula- 

 tor and its accompanying by-pass. 

 l'>om here the main continues and 

 passes under the cross house. At this 

 place branches of 1 1-2 inch pipe come 

 off and passing through 6-inch tile 

 emerge in the greenhouses under the 

 benches and by the side walls. 



Tender the benches the 1 1-2 inch 

 pipe divides into two 11-4 inch pipes, 

 one extending down each side of the 

 bench. These pass down to the other 

 end, cross over, and come back on the 

 opposite. There are also two wall 

 coils (me of which passes around the 

 end to the door. This then gives four 

 lines of pipe under each bench and 

 four on each wall, or 24 pipes in all. 

 Overhead pipes have been omitted al- 

 together. 



Each flow and return is fitted with a 



regulating valve at the corridor end 

 of the house, and each return before 

 it passes into the main return is fitted 

 with a check valve. Tlie water is re- 

 turned to the boiler by means of 

 double Morehead traps, one situated in 

 the cellar and the other over the boiler. 

 The greenhouses as well as the service 

 building are furnished with water and 

 electric light from the University 

 plants. 



Experiments. 



During the present winter these 

 houses have been devoted to an experi- 

 ment on carnations with chemical fer- 

 tilizers supplementing stable manures. 

 The object of the experiment is to de- 

 termine what chemical fertilizers 

 used with manure are best tor 

 carnation growing. The results from 

 this experiment will form the founda- 

 tion for future work on the amount to 

 use for best results. In this work 8 

 benches, each 100x1 feet, were avail- 

 able. Each bench was divided into 16 

 sections, 6x4 feet inside measurement, 

 this leaving some three feet over which 

 was divided into two small sections, 

 one at each end of the bench. The ob- 

 ject of this was to have sections pro- 

 tecting the exposed ends of the experi- 

 mental sections. 



Two benches, with 32 sections in all, 

 were used in each experiment, thus re- 

 peating the work four times. Each set 

 of benches was planted to a different 

 variety. The sections were numbered 

 from i to 32, each number standing for 

 a definite fertilizer combination. As a 

 further precaution the location of the 

 numbers on the benches, in the vari- 

 ous experiments, were changed so that 

 each of the numbers appears at differ- 

 ent places in the houses. Thus sec- 

 tions occurring at the exposed ends of 

 the house also occur in the center and 

 at the protected end.
