degrees will suffice, a 2-inch pipe is used, 

 while 2%-int;h pipe is required for a 

 minimum of 60 degrees. 



If the beds are so located that a good 

 fall can be secured, it will often be ad- 

 visable to provide bottom heat. This 

 can be secured by running a 2-inch pipe 

 on each wall as a flow and connecting 

 OTch of them with a return pipe nine 

 inches below the surface and eighteen 

 inches from the sides of the beds. 



In arranging the main flow, and return 

 pipes to supply the beds, one should 

 keep in mind that a 2-inch main will 



3iswer for 200 square feet of radia- 

 on; a 2*4-inch main is sufficient for 

 ^0 square feet, and 3-inch and 4-inch 

 mains may be used for 800 and 1,200 

 square feet, respectively, of radiation. 



HEATING OEOBGIA HOUSES. 



We are about to install a hot water 

 system in our two greenhouses, which 

 are 17x90 each. We wish to maintain 

 a temperature of 50 degrees with 15 de- 

 grees above zero outside. We have a 

 boiler of thirty horsepower, with a 

 wood-burning grate 2^4x4 feet. We are 

 putting in 2% -inch flow pipes, with six 

 returns of IV^-inch pipe in each house. 

 Will that be sufficient for our needs T 

 Are the boiler and pipes to be entirely 

 full of water when cold, or will there 

 have to be some space left for expan- 

 sion? V. G. — Ga. 



While we have had no practical expe- 

 rience in the heating of greenhouses 

 under conditions similar to those ctut- 

 lined in this query, we are of the opinion 

 that the radiation suggested would 

 answer if the houses were built side by 

 side and had but one exposed wall. The 

 sketch accompanying the letter indi- 

 cates that they have two feet of glass in 

 one wall at least. If each house has 

 glass exposed in both side walls, ,we 

 should prefer an additional return in 

 each house, although it would answer 

 without that in ordinary winter weather, 

 and the temperature mentioned could 

 be maintained with a little extra atten- 

 tion to the firing when the mercury di'ops 

 to 15 degrees above zero. 



From the sketch' it appears that the 

 plan is to have the returns run back and 

 forth under the benches. Instea'd of ar- 

 ranging them in that way, we should 

 connect the returns so as to make three 

 separate coils, each containing two l*,^- 

 inch pipes. Place one coil under each 

 side bench and the other under the 

 middle bench and connect each coil both 

 with the 214-inch overhead flow pipe at 

 the end farthest from the boiler and 

 with the 214-inch main return at the 

 other end of the house by means of 

 1%-inch pipes. If the houses have ex- 

 posed glass in both walls, use three re- 

 turns in the middle coil. Run the main 

 flow pipe about eighteen inches below 

 the ridge, with a fall of six inches in the 

 length of the house. Give the returns a 

 similar slope towards the boiler, which, 

 if possible, should be located so that it 

 will be entirely below the lowest part 

 of the returns, although it will answer 

 if the returns are slightly above the bot- 

 tom of the boiler. 



In order to secure a circulation, all 

 of the pipes must be filled with water 

 and, since the boiler will be consider- 

 ably lower than the highest part of the 

 aystem, it will always be filled. To pro- 

 vide for the expansion of the water, 

 connect the highest part of the system 

 with an expansion tank holding ten gal-

Gentlemen: Please send me 26 record plates 

 liVe the enclosed sample, and I want to say that 

 the machine, bought a good many years back, 

 is keeping up its good work right along. I think 

 it a very useful adjunct to good plant growing, 

 and it should be in every greenhouse, as refer- 

 ent e to it may often tell what is wrong with a 

 batch of plants. Very truly yours, 



Albkkt M. Herk. 



The actuating element of the Standard Record- 

 ing Thermometer is of lamina metal, which, be- 

 sides being extremely sensitive to temperature 

 changes, is practically indestructible. Record 

 charts are furnished either daily or weeVly, and 

 the whole mechanism is contained in an attractive 

 metal case fitted with lock and key, which insures 

 the record from being tampered with 



The clock movement is of extremely high grade; 

 everything about the instrument is up to the high- 

 est possible standard of manufacture.
