Ewbank's Hydraulics.

SINE iengl!l lHe eidDO!dtc anu lHteicSt'ie hi'so
ofHvaraulic Machinery by our fellow citizen, Mr..
Tuoy,s EwBAyK We said then. and are since
,bndantly confirmed IN the opinion, that it is
~. Of the most curious and remarkable books Of
me day; and we are glad 10 see that the pron-
rent English periodicals express the same apprc-
,atio, of its worth and character. We cut the
t1owing from long review in the At|lenaum :
aThe title-pagc bears the names of London
,nblishers but cursory glance at the interior
s,on raised our suspicious of the genuincness of
,bis London publishing. 1t purports to be written
smnly BY plain Thomas EwJank,-not f. K. S,
not NJ. /. C. E., not F. S. A.-simple Thomas
Ewbank. We searched in vain for the printers
name to guide us to the true origin of the work.
Bpt the internal evidences of its authenticity
are sufficiently strong Thomas Ewbank writes
himself citizen of New ork-has made hydraul-
les favorite study-has collected library on
the subect--has read lifetime of books-and
spent world of money and an ocean OF hmc
in laborous and systematic reading. The produce
Of all this labor he places al the disposal of those
who have similar tastes or pursuits IN tins &C
ceptable volume. We regret we cannot tell oar
readers more about the author than the book en-
sbles us to CLEAN. We remember to have met
the name in the discharge of some useful, prac-
teal or scientific function somewhere before, but
where or how we are unable 10 rccollect. But
We do not with the less confidence and satslac-
ton thank the author for his kindly-mcant, well
executed and very useful book.
"Of himself, the author tells US thus much
That circumstances led him in early life to take
an interest in practical hydraulics (pcshaps he is
an engineer that he became anxious TO obtain
an account Of all the contrlvanccs employed by
different people 10 raise water, whether for DO
nestle, agrcultura mining, manufacturing or
other purposes and that his disappointment was
great on finding no book containing all the in
formation he sought. This, he says, was thirty
or forty years ago. (ol course he is from fifty TO
seventy years old The want he felt he en-
deavored TO supply. During these thirty or
forty years he has read and collected great deal
from various and voumlnous sources. Doubt
less he has found in his much reading much rub
Dish; he has been hcapng up knowledge for
thirty years, and after much thrcshng, winnow-
lng and sitting, has separated the precious grams
Of wheat from much chat, and presents the
reader with the pabuum of the heterogeneous
mass as nutritious food for the rising generation
OF mechanics and engineers.
Z" In short Introductory paragraph the author
modcstly states what he has attempted, and still
more modestly his views and ambitions OF author
ship. 1t is merely justice to a laborous, conscl-
entious, intelligent and wcll-read author TO say,
that he has amply and ably fulfilled the excellent
intentions with which he has undertaken the
work and that he disarms criticism equally by
the outstanding merit Of the work, as by his own
retiring modesty."
The Mechanics Magazine speaks as follows:
EwDANK's Book OF HYDRAULIcs.--Mr Ew-
bank is an American cultivator of Mechanical
Science, of considerable reputc i'll his own
country, and well known, also, through It's scien-
life journals, to European readers, as gentle
man Of great practical knowledge, and a most
ingenious. sagacious and successful cxpcrimcnter.
We have, at different times, enriched our pages
by transferring to them productions of Mr.. Ew-
banks pen. The last was u very instructive
paper, on increasing the draft of chlmneys, IN
serted in our l00lst Number. Mr.. Ewbank is
the author, also, of many useful invenlions
among ,rAich he mast ,rorthy to be noted ts
probably, his process for timing lead pipes, (by
easing them, after being d'ncn and finished,
through bath Of liquid TIM nhich ,ca$ pa
tented a te,r gears ago in THIS country, ant IS
coming into e1tenSire aSc among u.s.
Mr.. Ewbank's most remarkable and valuable
contribution to MECHANICAL philosophy is, how
ever, beyond all comparison, the work before us.
Identities him to take rank at once with the very
best writers in this department of literature.
whether ancient or modern. If not so fertile in
original invention as Besson, or Belhdor, or
DeSaguiers, Ewbank shows far more comprc-
henSve knowledge of the inventions Of others,
and much Juster appreciation OF Their respective
merits: quite as entertaining as Bcckman, he ey-
ceeds HIM immeaSurably in practical usefulness
and while aiming, like Ferguson, at popular
style, nc brings to lis aid u livclincss of fancy,
depth of feeling, and cloquencc of expression, to

tanks book we have the ripe fruit OF long l;te's
