=Press Opinions.=

"A work of this extremely valuable character deserves to be made
widely known amongst colliery managers and mining engineers at home
and abroad."--_Coal and Iron._

"This book is, in a manner, unique. The literature of mining
accidents is fairly extensive, but it consists largely of
departmental Blue Books."--_Sheffield Daily Telegraph._

"A concise and lucid description of the principal methods pursued,
especially in fiery mines, and of the various appliances employed,
such as respiratory and rescue apparatus, dams, etc."--_Staffs
Advertiser._

"The prevention of spontaneous combustion in collieries and the
extinction of underground fires are duties that fall heavily on many
colliery managers. They should, therefore, welcome this translation
of Mr. Lamprecht's German treatise."--_Ironmonger._

"The book under notice supplies the needed full description,
drawings, and mode of using these new appliances in actual fires,
and should be studied by every colliery manager, seeing that even
our best managed collieries have not been free from fires, more or
less disastrous to life and property.--_Colliery Manager._

interest to the general reader."--_Halifax Guardian._

"The importance that gas and coal dust firing have attained of
recent years, and especially the great interest attaching of late to
the question of coal dust firing, makes the appearance of the
present volume most opportune."--_Iron and Coal Trades Review._

"The German author has long followed the development of various
systems of gas firing, and in the present treatise he discusses the
merits of appliances patented since 1885. His text and the numerous
illustrations indispensable to it will be found useful by all who

dealing with external plumbing work are sufficiently scarce to
ensure for Mr. Hart's new publication a hearty reception."--_The
Ironmonger._

"With Mr. Harts treatise in his hands the young plumber need not be
afraid of tackling outside work. He would do well to study its pages
at leisure, so that he may be ready for it when called
upon."--_Ironmongery._

"Rich in useful diagrams as well as in hints."--_Liverpool Mercury._

"The papers are eminently practical, and go much farther into the
mysteries they describe than the title 'Hints' properly
suggests."--_Scotsman._

"The articles are apparently written by a thoroughly practical man.
As a practical guide the book will doubtless be of much
service."--_Glasgow Herald._

"So far as the practical hints in this work are concerned, it will
be useful to apprentices and students in technical schools, as it
deals mainly with the most important or difficult branches of the
plumber's craft, _viz._, joint wiping, pipe bending and lead
burning.... 'Hints' are the most useful things to an apprentice, and
there are many in this work which are not to be found in some of the
text-books."--_English Mechanic._

22 PRYME STREET, HULL, _24th November_, 1894. "Gentlemen,--Your
books to hand for which accept my best thanks, also for circulars. I
myself got one of J.W. Hart's books on Plumbing from your traveller,
and having looked through the same I can safely recommend it as
being the best book I have seen. Mr. J.W. Hart treats exhaustively
upon soldering and pipe bending, which are two of the most essential
branches in the plumbing trade."

=Press Opinion.= "The author is evidently very thoroughly at home in regard to the technical subjects he has set himself to elucidate, from the mechanical rather than the artistic point of view, although the matter of correctness of taste is by no means ignored. Mr. Brown's style is directness itself, and there is no tyro in the painting trade, however mentally ungifted, who could fail to carry away a clearer grasp of the details of the subject after going over the performance."--_Building Industries._

=Press Opinion.=

"In the course of a hundred pages with some forty illustrations Mr.
Brown gives a very interesting and comprehensive survey of the
progress and development of decorative art. It cannot, of course, be
pretended that in the limited space named the subject is treated
exhaustively and in full detail, but it is sufficiently complete to
satisfy any ordinary reader; indeed, for general purposes, it is,
perhaps, more acceptable than a more elaborate treatise."--_Midland

"If all plumbers were to read this book, and if they followed the
instructions given, there would, we are sure, be fewer accidents
from household boiler explosions, and many lives might be saved. No
doubt the majority of householders know or care little about the
subject, but any one who wishes to adopt the most up-to-date system
of supplying hot water throughout his house will be able to do so if
he reads Mr. Hart's book and follows the instruction given. It is a
work that all who have charge of domestic water supply should study.
It is a practical and profitable book."--_Wigar Observer._

=Press Opinions.=

"The subject is dealt with fully in every little detail;
consequently, even the veriest tyro can take away some useful
information from its pages."--_Irish Farming World._

"Farmers are but little given to reading; but nowadays brewers have
to study their trade and keep abreast of its every aspect, and as
far as regards our trade, to them this book especially appeals, and
will be especially useful."--_Licensed Victuallers' Gazette._

"Like an oasis in the desert comes a volume upon the above subject,
by the Professor at the Higher Agricultural College,
Tetschen-Liebwerd, Germany, who has been fortunate enough to obtain
an excellent translator from the German in the person of Mr. Charles
Salter. The paucity of works upon the history and cultivation of
hops is surprising considering the scope it gives for an interesting
and useful work."--_Hereford Times._

"We can safely say that this book deals more comprehensively and
thoroughly with the subject of hops than any work previously
published in this country.... No one interested in the hop industry
can fail to extract a large amount of information from Professor
Gross's pages, which, although primarily intended for Continental
readers, yet bear very closely on what may be termed the
cosmopolitan aspects of the science of hop production."--_South
Eastern Gazette._

"This is, in our opinion, the most scholarly and exhaustive treatise
on the subject of hops, their culture and preservation, etc., that
has been published, and to the hop grower especially will its
information and recommendations prove valuable. Brewers, too, will
find the chapter devoted to 'Judging the Value of Hops' full of
useful hints, while the whole scope and tenor of the book bear
testimony to the studious and careful manner in which its contents
have been elaborated."--_Brewers' Journal._

"Considering the extent to which this country draws its hop supplies
from abroad, this translation of Professor Gross's volume will prove
an interesting and instructive addition to the library of any brewer
or brewers' chemist, the more so as the work of translation has been
admirably carried out in simple and vigorous English.... The volume
is one of a valuable series of special technical works for trades
and professions the publishers are issuing, and is the first so far
dealing with the brewing industry."--_Burton Mail._

"A work upon the above subject must be welcomed if for no other
reason than the dearth of books dealing with so interesting a theme,
but fortunately apart from this the book will afford excellent
reading to all interested in hops and their culture. Professor Gross
takes one over the whole field, by commencing with the earliest
history of the plant--so far back as the days of ancient Greece--and
from both practical, theoretical and scientific standpoints, deals
with the cultivation, classification and formation of the hop.... In
speaking of the production of new varieties sound information is
given, and should be of value to those who are always in search of
improvements."--_Hereford Journal._

"This work is, without doubt, the most thorough and extensive
compilation on hops ever yet offered to the public, and for this
reason should be warmly welcomed and appreciated by men interested
in the subject. Although primarily written for those engaged in the
industry abroad, and mainly Continental in theory and practice, it
nevertheless appeals to those connected with the hop growing and
brewing business in England, not only by way of a comparison, but
also as an instruction. The volume is at once practical and
scientific, is well got up, and teems with illustrations and
statistics. In a word, it is a book that should find its way into
the hands of all who are occupied in hop production and distribution
at home; and it also contains valuable information and suggestions
for the brewers themselves."--_Brewers' Guardian._

"This is a handbook which tells the reader everything about public

decidedly one of the best arranged volumes ever published, and there
is no doubt that the editor has been at great pains to obtain the
latest and most accurate information from all places. County,
district and parish councils, ministers of religion, and
schoolmasters everywhere should make themselves acquainted with its
contents. Its perusal cannot fail to serve the ends of the library
movement. The illustrations, of which there is a large number, are
very good."--_Western (Cardiff) Mail._
