The publication, at this moment, of stout

one who has made his name iustriouS BY setting
at naught the binding powers of these substances
on the walls and foundations of forts. has almost
the air of a practical joke; but General Gill

the experiments and researches embodied in the
work were conducted under the authority OF the
Engineer Bureau of the War Department. anu

and architect, into whose arts the clements
under discussion in this work enter for so much.
General Gilmore unlike the majority OF the
graduates Of our military school, who rest quite
content with what they have learned Ill the text
books. is fond of original investigation, and ne
has a talent for recording the results OF his III

Fort Pulaski, overlapping the narrow limits OF
a mere official paper, assumed the form OF
comprehensive ard instructive menlore on the
preaching power cf rihed ordnance, and takes
its place as valuable piece of military history.
The present monograph, though OH more
specialized subject, is an important contribution
to the branch of practical engineering which II
covers. Such work, embracing all the results
of the latest experiments, both in this country
and in Europe, was very much needed; ana
General Gillmore's detailed and exhaustive
treatment completely fills the desideratnm.
