By William Hewson, Civil Engineer. 
“ This is a valuable treatise on the principles and practice of embanking 
lands from river floods, as applied to the Levees of the Mississippi, by a highly 
intelligent and experienced engineer. The author says it is a first attempt 
to reduce to order and to rule the design, execution, and measurement of the 
Levees of the Mississippi. It is a most nseful and needed contribution to 
scientific literature.—Philadelphia Evening Journal.

THE MANUFACTURE OF STEEL. By M. L. Getoek, trans- 
lated from the French. By Lenox Smith, A. M., E. M., with an 
appendix on. the Bessemer Process in the United States, by the 
translator. Illustrated by lithographed drawings and wood-cuts. 
“ The purpose of the Work is to present a oareful, elahorate, and at the 
same time practieal examination into the physical properties of steel, as well 
as a description of the new processes and mechanieal appliances for its manufac- 
tnre. The Information which it oontains, gathered from many trustworthy 
sonrees, will he found of much value to the American steel mamifacturer, 
who may thus acquaint himself with the results of careful and elahorate ex- 
periments in other countries, and better prepare himself for successful cora- 
petition in this important industry with foreign makers. The fact that this 
yolume is from the pen of one of the ablest metallurgists of the, present day, 
cannot fail, we think, to secure for it a favorable consideration.—Iron Aye.
