a way that the excess of heat may be tempered before delivery; thus the supply of 

 fresh air is not cut off by closing the register. The area of the cold-air duct 



should be about 

 that of the sum 

 total of warm-air 

 pipes. This is 

 slightly excessive, 

 owing to the expan- 

 sion of hot air, hut 

 the deliver)' will be 

 freer than if it wen 

 smaller. 



Much has been 

 said as to the rrl:;- 

 tive merits of the 

 cast and wrought- 

 iron furnaces. It 

 is claimed that the 

 former, when hot, 

 is porous and will 

 allow the escape of 

 noxious gast-s; <>n 

 the other hand, the 

 larter is said to 

 suffer by expansion 

 and contraction so 

 that the joints are 



damaged to the same end. If both are properly made and set up, there is 

 probably little choice between them. The principal points to observe in the 

 choice of a furnace are that it should have few joints, be simple in construction 

 and working, and have a large amount of radiating surface in proportion to the 

 fire box. 



Registers should not be placed in the floor if it is possible to avoid it, as dust 

 falls into them easily, and is discharged again with the hot air, much to the 

 detriment of the latter. They are best placed in the vertical wall, and usually 

 at a point just above the baseboard. As most of the register designs are painfully 

 ugly, care should be taken in their selection. There are a few creditable patterns 

 on the market, for which we should be thankful. 



The best location in the room for a low register or radiator is perhaps 

 under a window, or, at least, in the outer wall. This, however, offers several 

 difficulties to the furnace, the chief of which lies in the extra run of flat pipe, 

 which hinders effective delivery. 



Owing to the several objections already stated, the furnace may be said 

 to be a good heating agent for a house of small area; the larger edifice requires 

 a different system. The furnace man will tell you that two heaters can be 

 used, and cite cases where even more have been installed with good results.
