Greenhouse Heating. 



If the winter keeps on as it has begun 

 a large part of the profits will go up the 

 greenhouse chimney. Coal consumption 

 has been exceptionally . heavy. It pays 

 to spend money to get a. heating system 

 that is economical of fuel. 



SIZE OF MAIN FLOW. 



How large a main flow will be re- 

 quired to furnish steam to 100,000 

 square feet of glass, the steam to be 

 carried 300 feet #om the boilers, with 

 a pressure of twenty-five pounds? 



H. O. 



If the pipe is well insulated it need 

 not be larger than 5-inch, although bet- 

 ter results can be secured if a pressure 

 of at least forty pounds is carried in 

 the main flow pipe. F. K. 



GENEBAL PURPOSE HOUSE. 



We have a house we wish to pipe for 

 hot water. It is 16x90 feet, four feet 

 high at the sides and nine feet high at 

 the ridge, with no glass in sides or 

 ends. The flow pipe will have to run 

 uphill from the boiler to the farther 

 end. Where shall we connect the ex- 

 pansion pipe! The boiler pit is eight 

 and one-half feet below the floor of 

 the house. We want to use 2-inch 

 flows and 1*4 -inch returns, as we have 

 a lot of those sizes of pipe on hand. 

 How much piping and what size of 

 boiler will be needed? The temperature 

 is seldom below 15 degrees below zero. 

 We want a house for a general line of 

 plants for spring sales. C. L. 



For a house of this length it is al- 

 ways best to use 2-inch pipe for the re- 

 turns and 2% -inch for the flows, but 

 with the deep boiler pit fairly good 

 results should be secured with 1*4 -inch 

 pipe in the returns. It will require 

 about 650 square feet of radiation to 

 furnish a temperature of 60 degrees, 

 and for this it will be advisable to use 

 a boiler with a radiation rating of 800 

 to 900 square feet. For the radiating 

 surface use four 2-inch flows and 

 twelve 114-iDcli returns. Instead of 

 this, three 2V^-inch flows and eight 

 2-inch returns could be used with bet- 

 ter results. Connect the expansion tank 

 with the main return near the boiler.

FUMES FROM HEATING PIPES. 



In The Review of December 8, page 

 17, I note that C. D. H. has trouble 

 with his pipes because of painting them 

 with chrysolite. This preparation will 

 act just like gas. C. D. H., or others 

 who use it, will note that as soon as 

 he began firing heavily his plants 

 failed, and he will not be able to make 

 any headway until the preparation is 

 removed from the pipes. There is only 

 one way to do this. Some twfinty- 

 seven years ago I was engaged as a

private gardener at Glen Island. I 

 started there March 13 and just as soon 

 as I put my head inside the greenhouses 

 I noticed a peculiar odor. On inquiry I 

 found the pipes had been painted with 

 a preparation containing this ingre- 

 dient, so I went to the boss and told 

 him it was no use trying to grow any- 

 thing in those houses. He begged me 

 to stay with him, so I finished out the 

 year. As soon • as the weather got a 

 little warmer the plant stalks showed 

 signs of life, so rather than fire I left 

 them to take their chance, and they 

 quickly recovered. The following fall, 

 just as soon as we began to fire, it 

 was the same thing again. The houses 

 were each eighty-one feet long, with 

 eight lines of pipe, so I decided to cut 

 them all off. We had plenty of men. 

 "We took the boilers down and cut all 

 the pipes next to the boiler. Then we 

 strung the pipes along on bricks, taking 

 care that they could not warp. Then 

 we covered them with wood and built 

 a fire, and you should have smelt the 

 fumes just as they got good and hot! 

 After that we put them back, and 

 that ended all our trouble. C. D. H. 

 will have to do this before his trouble 

 ends. We cut out the pipes early in 

 the morning, and as they were only 

 cut off at each end it left only sixteen

The Market. 



Home-grown roses are not plentiful 

 and the demand is greater than the 

 supply. Killarney and White Killar- 

 ney are the leaders and bring better 

 prices than other varieties. There is 

 quite a shortage in American Beauties 

 and most of the stores are supplied 

 from Chicago. 



Carnations are scarce and the de- 

 mand is heavy, with wholesale prices 

 up to 5 cents December 15, and none of 

 the local growers can promise any 

 great quantity for Christmas. Violets
