Qreeflhoose Beating. 



Nobody seems to be worrying about 

 that coal-miners' strike. In fact, the 

 operators in the bituminous fields ap- 

 pear to welcome the shut-down as pre- 

 venting overproduction, while the half- 

 dollar drop in the price of anthracite 

 took effect as usual April 1. But it is 

 not safe to let the supply in the bunkers 

 run low. We shall have frosty nights 

 this month if experiences are not a poor 

 guide.

SIZE OF SMOKESTACK. 



I have a tubular, return boiler, four- 

 teen feet long, with twenty-five 4-inch 

 tubes, fourteen feet long. My grate is 

 four feet wide and five feet long. The 

 dust chamber at the back is four feet 

 wide, three feet six inches high and two 

 feet deep. I burn a good quality of 

 West-Virginia soft coal, but fail to make 

 the steam I require for a good circula- 

 tion. The brick stack is nineteen inches 

 square, inside, and is twenty feet high 

 from the top of the boiler. It is but ten

feet high above the roof of the boiler- 

 shed.- Before building it higher, I should 

 like to know if nineteen inches square is 

 large enough to give us proper draft. I 

 have four houses 20x100, one 15x100 and 

 a shed 12x70. I have a high pressure 

 steam gauge, and when the main valve is 

 open I cannot make steam enough to 

 register. There are no buildings or trees 

 near to mar the draft. Please give the 

 proper dimensions of stack for the boiler 

 I have. R. S. 



The area of the chimney is almost ex- 

 actly right for the grate area. If the 

 height of the chimney can be increased 

 without decreasing its internal diameter,

Why buy half a boiler and then get a 

 mason to build the other half ? When you 

 buy a Bumham you buy a base too. No 

 bricking-in expense.
