VENTILATORS. 



Some time since we furnished our readers with 

 a cut and description of Dr. Espy's remedy for 

 a smokey chimney. At the time we suggested 

 that the Doctor's invention was not altogether 

 novel, and now we are authorized to say that it 

 is not the best form of using the apparatus. — 

 Some experiments have been instituted by Mr. 

 Mott, of New York, which, to use his own 

 words, have resulted as follows. To those who 

 have suffered from the evil of a smokey chim- 

 ney we need not apologize for introducing the 

 article. 



"To test the relative value of the various 

 chimney caps and ventilators in use, 1 have 

 made, during the past twelve months, many ex- 

 periments, assisted by Thomas Ewbank, Esq. 

 of this city. Many caps were sent to me for 

 trial by others. The experiments were wit- 



nessed by members of the American and Me- 

 chanics' Institutes, and several other scientific 

 gentlemen, who were much interested, and ex- 

 pressed their surprise at the results. 



" Trials were made in the following manner : 

 A glass tube, of one inch bore, and eighteen 

 inches long, was provided ; on the top of this 

 tube the various caps were placed ; the lower 

 end of the tube was immersed in a vessel of 

 water, the upper end with the cap, each in turn, 

 was placed in the blast produced by a blowing 

 apparatus driven by a six-horse steam engine, 

 used for melting iron in my foundry at Morrisa- 

 nia. The blast was through a six inch pipe 

 contracted to three inches, the caps being placed 

 about twelve inches from the pipe, so that the 

 wind could have free action on the outside as 

 well as inside of those caps that were hollow. 



" More than one hundred caps were tried, con 

 sisting of the various kinds in use in this coun- 

 try and in Europe. The experiments were re-
