fervid air. This object once attained, advantages belonging to 

 the system become apparent. The air flue, which, unlike the 

 old smoke flue, requires no special care in its construction, 

 delivers its heat through slides, which by a simple adjustment 

 apportion the supply at will, or they can be made to shut it off 

 altogether — no mean advantage when sun heat meets tire heat 

 on a fickle day. The air so admitted is fresh air, bearing with 

 it the healthful influences of the outer atmosphere, and caus- 

 ing, by the velocity of its inco min g, the aerial perturbation so 

 grateful to plant life, and for every gallon of fresh air admitted 

 a like quantity is expelled ; so assuming the area of inlet to be 

 4 square feet, a like area of outlet will be required, and this is 

 necessarily equivalent in a house 60 feet long to half an inch 

 of top air always left on. 



I will not go further into detail, unless I find that you think 

 the subject worthy of discussion, and that some of your readers 

 care to discuss it. — E. Houshan.
