in front and a trussed glass roof. Immediately back of the engine- 

 house is the boiler room, 40 feet by 60 feet, with room for four 

 boilers, coal bunkers, etc., and back of this again will rise the 

 large new chimney 130 feet in height. Over the rear part of the 

 engine-room will be built a four-story connection between the 

 old and new factories, 33 feet by 40 feet in size, and of a design 

 to harmonize and imite the ditfercnt styles of buildings. The 

 engine-room will contain a tine new Harris-Corliss engine of 400- 

 horse power, built especially for the Company, and through the 

 room, and half way to the ceiling, will be a passage or walk 

 where visitors in passing through to the new factory may see the 

 working of the engine from above. 



The new factory will contain a large elevator and two fire- 

 proof stairways entirely separated from the floors by thick brick 

 walls. The heating will be done by a large blower forcing fresh 

 warm air into each story, and the most improved methods of 

 ventilation will be employed, entirely independent of the win- 

 dows. Every room will be equipped with automatic sprinklers, 

 and the plumbing will be of the best appliances. The buildings 

 will be lighted by electricity from the Company's plant of two 

 400-light Edison dynamos, the power of which is given by a 

 separate loo-horse power engine. 



The cost of the works which ai'e now being constructed will be 

 about $50,000. 



CORRESPONDENCE. 



I think your determination to enlarge and illustrate the Jour- 

 nal, a wise one. 1 read it with much interest and profit. — JV. 

 W. Roxvlee. 



I am pleased to hear that you intend to increase the size of 

 the Journal next year. The increase of interest which this will 

 enable you to give the Journal will no doubt amply repay 

 subscribers for the increased cost. The price will still be low 

 for a journal of its scope and character. — 5". W. Cochran. 



For my part, I would not object if the price were tripled. — 

 C. E. Stoner. 



Be sure to find me a subscriber at $2, or, if it need be, even at 

 $3, per year, as the magazine is not only a recreation but a real 

 use to me. — P. W. Gayer.
