house contains 10 double beds of retorts, worked by 20 furna^'es, and 

 is capable of heating and keepin:^ in action 60 retorts. 'I'he g^eneral 

 construclion of these retorts gives ample evidence of the superior talent 

 of the artisan. A very valuable improvement is introduceil, in set- 

 ting these retorts, by the chief engineer of the company, Mr. Charles 

 Rooine, to whom great credit is due, for his general design and exe- 

 cution of the whole of these extensive works; and also to William 

 H. Smith, archite. t and carpenter, Benjamin M. Claik, mason, Jacob 

 Steinerl, fiamer, and Messrs. Mott and Ayers, constructors of the iron 

 roof. 



The committee being desirous of not overlooking true merit in any 

 of tlie laboring classes of society, mention with pleasure the fact, as 

 they are intormed. that the numerous laborers employed in the erec- 

 tion of these works, have distinguished themselves for sobriety, in- 

 dustry, and orilerly conduct. 



The committee are highly gratified t'> witness the great display of 

 workmanship, in the cf)nhtruction of these works, by .'Imericins, 

 showing the very advanceil state of the mechanic arts in this country, 

 and that the whole- establishment deserves to be ranked among the 

 inost magnificent and useful institutions in the United States.
