A GREENHOUSE POWER PLANT. Mechanical Aids to the Grower. If you did not see the caption of the illustration at the bottom of the page, you might take it for the power plant of a street railway. Or, perhaps, you would think it was the city water works. But it is neither; it is the boiler house and service building of a florist, the J. W. Davis Co., near Daven- port, la. It serves to show how large a job it is to provide the heat and power for the mechanical working of a big greenhouse plant. Not merely the fact that it is a large plant makes this part of the work of so much impor- tance; today there are a great many uses to which the grower puts his steam that a few years ago were un- heard-of in the florists' business. In the days gone by the majority of the growers turned off steam entirely during the summer, cleaned out the boilers and gave them a rest until the cool days of autumn. Nowadays it is the exceptional large grower who does not keep up his fires the year around. The cool evenings in many places, espe- cially where there is a sea or lake bJeeze, make it of great advantage to have on hand a little steam, particu- larly to rose growers. These have found that the best preventive of mildew is driving out the warm, moist- ure-laden air in the early evening by turning, on a little steam and opening the ventilators, instead of allowing the coolness of the night to condense the moisture in tbe air shut in under closed ventilafors. Putting Steam to Other Uses. Since the custom has become general of carrying moderately high pressure on the boilers, brought down in the heating coils by a regulating valve, the steam has come to be used for dozens of other jobs than the original —heating. There are several kinds of pumps that can be run: water pumps, fertilizer pumps, vacuum pumps and
