Greenhonse Healing 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 should be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



THE FUEL SITUATION. 



In its weekly review of the coal situa- 

 tion the Coal Age says that signs are 

 not wanting that the bituminous coal 

 market is now on the mend, and both 

 prices and production are already be- 

 ginning to reflect the change in •condi- 

 tions. Coals of good quality are not 

 being sold at less than the recent gov- 

 ernment prices and operators as a rule 

 are adhering closely to their policy of 

 producing only what the market will 

 absorb. 



Operators in all the producing dis- 

 tricts are watching the current market 

 conditions closely and efforts are many 

 to close contracts for the next coal year 

 —April 1, 1919, to March 31, 1920. 



The continued drop in the output of 

 soft coal for the last six weeks was 

 checked during the week ended March 

 1 by the production of 8,088,000 net tons, 

 an increase of more than 363,000 net 

 tons over the output for the week ended 

 February 22. As compared to the pro- 

 duction of the similar period in 1918, 

 however, this is a drop of 3,519,000 net 

 tons. 



"Unsettled" is the word that best 

 characterizes the present condition of 

 the anthracite industry. Even with the 

 mines working only half time the oper- 

 ators find it difficult to dispose of their 

 output. Instead of the decrease in 

 prices loudly heralded in some quarters, 

 the announcement has been made that 

 beginning with May 1 there will be an 

 increase in the price of domestic anthra- 

 cite of 10 cents a ton each month until a 

 maximum increase of 50 cents a ton is 

 reached September 1. The so-called 

 independent companies will increase 

 their prices during the same period 15 

 cents per ton. 



The production of anthracite during 

 the week ended March 1 is estimated at 

 1,102,000 net tons, a slight decrease over 

 the preceding week 's output, but 834,000 

 net tons lower than the production dur- 

 ing the corresponding week in 1918. 

 The total output of anthracite for the 

 coal year to date is 87,122,000 net tons. 



THE RETURNS ARE TOO LOW. 



Finding that I am unable to main- 

 tain a satisfactory temperature in the 

 greenhouses of which I recently took 

 charge, I am applying to The Review 

 for aid and am enclosing a sketch of the 

 heating system. When the outside tem- 

 perature is 15 degrees below zero, the 

 highest temperature that I can obtain 

 in the houses is 45 degrees. Even to 

 get that result requires constant firing, 

 as well as close attention to prevent the 

 water from boiling over and leaving the 

 pipes empty. I suspect that the trouble 

 is sluggish circulation, but I am at a 

 loss to know the cause of the difficulty 

 and the best way to remedy it.
