CEMENT FOR CAST-IRON PIPE. 



What is the best material to usir^oiy 

 cementing 4-inch cast-iron water pipe for 

 greenhouse heating? J 



In answer to your query regarding a 

 cement for cast pipe, I have selected the 

 following from several recommended by 

 Bailey : ' ' Sal ammoniac, two ounces ; 

 sulphur, one ounce; clean iron borings or 

 filings, reduced to powder, twelve 

 pounds; water enough to form a thin 

 paste." L. C. C. 



STEAM HEAT FOR TWO HOUSES 



We have two greenhouses, each 25x65 

 feet, with no partition between them. 

 The side walls are three feet high and 

 the height to the ridge is ten feet. The 

 side walls and one end of the houses 

 are entirely of cement construction; the 

 other end is cement to a distance of 

 three feet from the ground, and above 

 that it is glass. The houses are shel- 

 tered from the wind. How many runs 

 of 1%-inch steam pipe will be required 

 to heat to 56 degrees when the outside 

 temperature is 10 degrees below zero! 

 What would be the size of the flow pipe 

 in each house? We should like to have 

 all 114-ihch pipe under the gutter plate 

 and on the side walls, as we will have 

 solid beds. H. K. S. 



Each house should have a 2-inch riser 

 and sixteen 1^-inch pipes. These can 

 be arranged in coils and hung on the 

 side walls. The main flow should be 

 under the ridge and distribute to the re- 

 turns at the far end of the house.

TO MAKE BOILER COMPOUND. 



A Colfirado correspondent of the Iron 

 Trade Review reports a new discovery of 

 a scientific nature, which may result in 

 the establishment of a factory at Pueblo 

 for the manufacture of boiler compound. 

 A prominent chemist has discovered a 

 process by which a valuable compound 

 can be made, the principal ingredient of 

 which is extracted from the cactus plant. 



There is only one variety of cactus 

 which will serve the purpose, the botani- 

 cal name being epiphyllum. The process 

 includes the reduction of the cactus to a 

 pulp and in this manner the juice is ex-

The Standard 

 Steam Trap 



is acknowIedRed the best for the 

 floiist because it is durable, and does 

 its work without trouble and annoy- 

 ance, saving its cost by the econoniy 

 in coal bills.

tracted and mixed with other vegetable 

 juices. The main claim for this com- 

 pound is that it contains no chemicals 

 which are detrimental in that they at- 

 tack the metal sneets of the boilers and 

 cause them to corrode. 



'Ine purpose of this compound is to 

 eliminate scale forming constituents from 

 the feed water, and in this manner pre- 

 vent the formation of scales in the tubes. 

 They claim it can be put on the market 

 at a much lower cost than the average 

 compound, for the reason that the cactus 

 plant will grow in almost any ground and 

 without cultivation. 



VACUUM HEATING. 



Frank A. Simonds, of Grand Rapids, 

 Mich., has removed to Detroit and organ- 

 ized the Simonds Heating and Specialty 

 Co., one of the first steps of the new 

 concern being to mail to florists copies 

 of the paper Mr, Simonds read before 

 the Detroit Florists' Club and which was 

 published in the Review at the time, a 

 couple of years ago. In it Mr. Simonds 

 told about the vacuum system of heating 

 by steam, then a quite new subject to 

 florists, but since adopted, in one form 

 or another, in quite a number of green- 

 house plants. 



A vacuum system of steam heating 

 differs from the ordinary system of 

 gravity return in the maintaining of a 

 partial vacuum in the main and return

pipes. The vacuum is created and main- 

 tained in the systems used in green- 

 houses, including the one devised by Mr. 

 Simonds, by means of a vacuum pump. 

 The result is that the steam circulates 

 with much less pressure than would be 

 required without the aid of the vacuum 

 devices. When a heating engineer un- 

 dertakes to show how a vacuum system 

 works, he ordinarily obscures his mean- 

 ing from the florist by employing a lot 

 of incomprehensible technical terms, but 

 wherever a good vacuum system has been 

 installed in a greenhouse it has proved 

 the correctness of the idea and has re- 

 sulted in the aidoption of the system by 

 others. For instance, Chamberlin & 

 Bunker, Fremont, Mich., say that a sav- 

 ing was made in the amount of pipe 

 required as between the vacuum and 

 gravity of steam. They aire using the 

 exhaust steam from a mill 310 feet from 

 the greenhouses and have no diflSculty
