adopted by the operators." The Sep- 

 tember prices at the mines, $1.40 for 

 mine-run and $2.25 for lump and egg, 

 are firmly maintained. 



A BOILEB AND CONNECTIONS. 



I have an upright boiler, four feet 

 in diameter, ten feet in height, and 

 containing 118 2-inch flues. It is set 

 in a pit deep enough so that six feet 

 of the water in the boiler is below the 

 return pipes and four feet of the water 

 is above the returns. Two S^^-inch 

 flows rise four feet above the boiler 

 and run with but a slight fall to the 

 end of the houses, which are 100 feet 

 long. There are two 3 1^ -inch return 

 openings at the bottom of the boiler. 

 • I shall connect the water tank with 

 the boiler. The tank is thirty fee* 

 above the top of the boiler. That will 

 provide a pressure, I think, of about 

 sixteen pounds. Will that be sufficient 

 to cause the water to circulate satis- 

 factorily? I have been using steam, 

 but wish to change to water if I can 

 get a good circulation under these con- 

 ditions. I have only about 6,000 

 square feet ef-glass or its equivalent. 

 Where should the pipe from the tank 

 be connected — at the bottom or the 

 top of the boiler! T. L. S.— Mo. 



While it would be preferable to use 

 a horizontal boiler of the dimensions 

 stated, good results may be obtained 

 with the arrangement outlined. The 

 expansion tank should be connected 

 with the highest point in one of the 

 flow pipes, and a branch pipe should 

 lead to the other flow pipe. This 

 would do away with the necessity for 

 air valves in the flows; otherwise the 

 connection could be made at any point. 

 Since a serious explosion might result 

 if the pipe to the tank happened to 

 freeze, I would advise the use of a 

 safety valve on the expansion pipe.
