FROM STEAM TO HOT WATER. 



We have three greenhouses, of King 

 construction, each 14x100 feet and eleven 

 feet to the ridge, with side walls seven 

 feet high. These houses are connected. 

 They are piped for steam, with a 2%- 

 inch main and with 1^4 -inch returns to 

 the main return, which is 2-inch. I want 

 to change the system to hot water and 

 want to know how many pipes it will 

 take, using the same size of pipe as we 

 now have. What capacity of hot water 

 boiler will we need, here in North Caro- 

 lina, to keep the houses at 60 degrees 

 when the outside temperature is 15 de- 

 grees above zero? S. T. F. 



I do not think it wise to attempt to 

 transform your system into a hot water 

 plant with 1^-inch pipes 100 feet long. 

 I never advise the use of pipes smaller 

 than lil>-inch for hot water. On this 

 basis it will require thirty 1%-inch pipes 

 for returns and a 3-inch overhead flow 

 for each of the three divisions. 



A boiler for this plant should have a 

 rated capacity for at least 2,000 square 

 feet of radiation. L. C. C. 



THREE NARROW HOUSES. 



I contemplate building three short- 

 roof houses, each 11x200 feet, connected 

 ridge and furrow; no partitions; 8-foot 

 posts, with five feet of glass in the sides. 

 How large a steam boiler would I need 

 to heat these to 55 degrees at 10 de- 

 grees below zero, in this Massachusetts 

 climate? How large should the flow 

 pipes be and how many runs of 114-inch 

 pipe would I need? How much pitch 

 should the piping have for steam? How 

 near can the boiler be set to the level 

 of the floor of the greenhouses; or, in 

 other words, how much drop must there 

 be from the returns to the bottom of the 

 boiler? S. S. P. 



The three houses require seventeen 

 runs of 114-inch pipe. In order to heat 

 them, you should have a boiler rated to 

 carry 2,000 square feet of radiation. A 

 steam boiler with 250 square feet of 

 heating surface will do the work. The 

 boiler, if you wish to use a gravity sys- 

 tem, should be located so the water line 

 of the boiler will be at least two feet 

 below the lowest point in the return 

 pipes in the houses. If you use a flow

 which would be a good plan, a 2 V^ -inch 

 pipe will be sufficient. 



If the returns have a fall of eight 

 inches in the 200 feet they will work all 

 right, but care must be taken to grade 

 them evenly, so there will be no buckles 

 or traps. L. C. C.

The Market 



Every one is happy, for although 

 things are not rushing, still there is 

 plenty of work. The same amount of 

 help will be found at all the stores and 

 there seems to be work enough to keep 

 them out of mischief. 



Keports from the commission houses 

 show that all stock cleaned up well last 

 week, with the exception of some kinds 

 of bulbous flowers. Prices received are 

 not 80 good as last year, but the unusu- 

 ally heavy carnation crop may be respon- 

 sible for this. 



Roses bring anywhere from 3 cents to 

 10 and 12 cents for some exceptionally 

 fine Maids. 



Carnations, to the retailers, are from 

 $1.50 to $2.50 per hundred. 



Qub Meeting. 



One of the most wide-awake meetings 

 the Detroit Florists' Club has held for 

 some time took place March 18. The at- 

 tendance was larger than usual. 



Albert Pochelon gave a detailed ac- 

 count of his recent trip east. He visited

 tures was the amount of time and money
