The Florists^ Review 



AOODST 8, 1012. 



some consumers are already taking in 

 ,coal over and above their current require- 

 ments. Most of them are covered by 

 contract, so that the movement of this 

 extra tonnage does not figure in the spot 

 market. Some few, however, are shop- 

 ping around and it is reasonable to sup- 

 pose that their number will increase 

 from week to week. Those wishing to 

 place annual contracts find that they 

 have to pay as much as they would had 

 they closed in April or May, and they 

 also encounter a good many shippers 

 who have secured all the business they 

 want except at a higher figure than can 

 now be obtained. 



IN SOUTHERN LOUISIANA. 



Will you give me a little advice about 

 the piping of my greenhouse, for hot 

 water! The house is 24x100 and twelve 

 feet to the ridge, with two feet of glass 

 in the south side. The walls are four 

 feet high and double boarded. Will two 

 2-inch Hows and six 2-inch returns be 

 enough to heat the house to 70 degrees, 

 with an outside temperature of 10 de- 

 grees above zero! Or would it be better 

 to use two 2-inch flows and ten li4-inch 

 pipes, distributed equally on both sides 

 of the house? What would you sug- 

 gest? Please state, also, what size of 

 boiler would be necessary. M. S. 



It will be well to have a boiler with 

 a rating of 1,200 feet or slightly more 

 to heat the greenhouse. The number of 

 both flows and returns suggested is al- 

 together too small. Either use five 2- 

 inch flows, or preferably three 2i^-inch, 

 and twelve 2-inch returns. 



QBEENHOUSES AND RESIDENCE. 



Kindly give us information as to the 

 size of chimney that is necessary for a 

 thirty horse-power, horizontal boiler, 

 with grates forty-two inches square. We 

 had to clean the tubes every four hours 

 in cloudy weather and once a day in 

 windy weather last winter, and we be- 

 lieved this was due to the smallness of 

 the chimney, which is eighteen feet high 

 and fourteen inches in diameter. We 

 should prefer some cheaper sort of stack 

 than the present brick one. If it would 

 be better to retain the brick one, kindly 

 state how much it would be necessary to 

 add to the height. 



We also wish to heat our four-room 

 dwelling, besides the greenhouses, which 

 cover a space of about 5,200 square feet, 

 and we should like to know whether 

 our boiler is large enough to heat the 

 entire place, in this Illinois climate. We 

 grow roses, carnations, and a general 

 stock of plants. Would you advise us 

 to run the pipe directly from the boiler, 

 or would it be satisfactory to take oflf 

 one flow and attach it to the purlin 

 posts? With this arrangement it would 

 only be necessary to run the pipes three 

 feet underground to the boiler, but we 

 could not see how we could place our 

 returns if the pipes had to be dropped 

 down about thirty inches below the low- 

 est return in the farther end of the 

 greenhouses. We carry five pounds of 

 steam on the boiler in zero weather and 

 one pound in average winter days.

While it would be better to have a 

 chimney sixteen inches in diameter and 

 thirty feet high, it would probably 

 answer if the present chimney could be 

 carried up to the height of thirty-six
