36 TRANSACTIONS OF THE 



expense of the board from Chicago, and exhibited at Palace 

 Garden, and also at Hamilton Park. For the exhibition of 

 this plow, deemed by many the most successful working steam 

 plow as yet devised, and to which the United States Agricultural 

 Society, at its last fair held at Chicago, and the Illinois Central 

 railroad company have both awarded large premiums, the board 

 paid the ingenious inventor one thousand dollars. Among other 

 new inventions exhibited were a wrecking pump of great capa- 

 city ; a steam fire engine, giving Carey's rotary pump great 

 efficiency; six steam and air engines, exhibiting new improve- 

 ments; two ingenious apparatus for instantaneously lighting a 

 large number of gas-burners by electricity; a new sub-marine 

 explorer, and a contrivance to enable the deaf to hear at a dis- 

 tance the ordinary tones of a speaker's voice. The great variety 

 of improved sewing machines exhibited, forty-five in number, shows 

 the activity prevailing in this interesting department of invention.
