THE MANUFACTURE OF IRON IN ALL ITS 

 VARIOUS BRANCHES: 



To which is added an Essay on the Manufacture of Steel, by 

 Frederick Overman, Mining Engineer, with one hundred and 

 fifty Wood Engravings. A new edition. In One Volume, oc- 

 tavo, five hundred pages $5.00 



We have now to announce the appearance of another valuable work on the 

 subject which, in our humble opinion, supplies any deficiency which late im- 

 provements and discoveries may have caused, from the lapse of time since the 

 date of *• Mushet" and " Schrivenor." It is the production of one of our trans- 

 atlantic brethren, Mr. Frederick Overman, Mining Engineer; and we do not 

 hesitate to set it down as a work of great importance to all connected with the 

 iron interest; one which, while it is sufficiently technological fully to explain 

 chemical analysis, and the various phenomena of iron under different circum- 

 stances, to the satisfaction of the most fastidious, is written in that clear and 

 comprehensive style as to be available to the capacity of the humblest mind, 

 and consequently will be of much advantage to those works where the proprie- 

 tors may see the desirability of placing it in the hands of their operatives. —

The object of this "History of Propellers and Steam Navigation" is twofold. 

 One is the arrangement and description of many devices which have been in- 

 Tented to propel vessels, in order to prevent many ingenious men from wasting 

 their time, talents, and money on such projects. The immense amount of time, 

 etudy, and money thrown away on such contrivancus is beyond calculation. 

 In this respect, it is hoped that it will be the means of doing some good.—

 another while on the application of them to the use and service of mankind.— »
