FUEL OIL BECOMINO SCABCE. 



From the western headquarters of the 

 Standard Oil Co., at Chicago, comes the 

 announcement that it will cease the sale 

 of fuel oil after Decemb^ 1. The phe- 

 nomenal increase in the ^0 of gasoline 

 for engines propelling automobiles and 

 other machinery is given as the cause 

 for abandoning the fuel oil branch of 

 the business. It has been found more 

 profitable to keep the oil and refine it 

 rather than sell it for fuel purposes. 



There are quite a number of green- 

 houses that burn oil, but a majority of 

 these are located outside what the oil 

 interests consider as the Chicago terri- 

 tory. How these oil burners will be af- 

 fected is not yet apparent, except that 

 unquestionably the cost will be higher. 

 At present the western independent oil 

 companies are somewhat at sea over the 

 course to pursue. Their capacities in 



fhe middle west territory are far too 

 mall to take care of the entire demand. 



TO PREVENT BOILING OVER. 



1 noticed in The Review of October 

 24, page 94, an inquiry under the title 

 of "Expansion Tank Boils Over," by 

 H. H. K. I had the same trouble last 

 winter, two or three times. . It was 

 caused by the water getting hot enough 

 to begin running out of the expansion 

 tank, and this action, when once start- 

 ed, kept siphoning the water out of 

 the system, because the expansion tank 

 could get no air. I put on a check air- 

 valve at the top of the tank, which 

 was a little higher than the pipe which 

 carried the overflow. This remedied 

 my trouble. I also put a water gauge 

 on the expansion tank, and as soon as 

 r saw water in the gauge I prevented 

 it from getting any higher, which gave 

 me ample room for expansion, as the 

 gauge was at the lower edge of the 

 expansion tank. 



It goes without saying, that if water, 

 when it has started to run, does not 

 have air or some means of relieving 

 the pressure, it will continue to siphon 

 itself till it has run out too much or 

 more than is convenient. Perhaps if 

 H. H. K. will put an air check-valve on 

 his tank, it will be as beneficial as 

 mine was to me. P. Waterer.

To heat the house described use five 

 21^-inch flow pipes and twenty 2-inch 

 returns. One flow can be upon each

 and two of the purlins. Place four re-

 Carry 40 or 50 pounds pressure
