about 12 minutes. The whole operation is regulated by a time- 

 piece, hence the uniformity in the goodness of the article made. 



The rolling-mill is of the most substantial build, the rollers are 

 8 feet long and 20 inches diameter, with a reversed motion attached 

 to the same, thereby saving much laborious manual labor and time 

 for the quantity of work performed. 



In this establishment the separate departments for making the 

 pipes and rolling sheet lead, together with other matters and things 

 belonging thereto, is so admirably arranged that the manual labor 

 required therein is performed with comparative ease and facility. 



This manufactory is an excellent illustration of what can be ac- 

 complished in the way of modern improvements, when conducted by 

 science and skill. The special interest of the operators or workmen 

 engaged in the manufacture of metals, constitutes a main feature in 

 the construction of this improved machinery. The interest of owner 

 and workman are so equitably combined as to insure a satisfactory 

 and profitable result of their united labors. 



A visit to this model establishment cannot fail to be pleasing and 

 useful, particularly so to those engaged in such like work. Their 

 accomplished and scientific Mr. Smith is ever ready to extend to all 

 such a hearty welcome to the works of Le Roy & Co., 261 & 263 

 Water-street. 



Remaining, dear sir, 



Yours truly,
