POPULAR SCIENCE REVIEW. 
former reports to the question of the falling off in the supply of food fishes 
and the means to he adopted for restoring it to a satisfactory condition ; in 
an appendix exceedingly interesting details are given with respect to the 
vigorous attempts which have been, and are still being made, to restock the 
fresh waters of the United States with those valuable species of fishes, 
especially salmonidae, which formerly swarmed in them, but have given way 
before the rapid increase of population. But the greater part (nearly 800 
pages) of the stout octavo volume before us is occupied by a most elaborate 
report on the history of the American whale fishery, from its commencement, 
in the year 1600, to the present day, illustrated with six plates, giving outline 
figures of different species of whales and the instruments used in their cap- 
ture, and accompanied by a tabular list of all the voyages that have been 
made by American whalers and their results. As a statistical record this will 
be found of the highest value. 
URE’S DICTIONARY OF ARTS, MINES, AND MANUFACTURES : 
SUPPLEMENT.* 
O N the completion of the third volume of this Dictionary, in 1873, it was 
found that several of the articles contained in the earlier portions of 
the work required amplification, in consequence of the rapid advances which 
had taken place in the various applications of science. In order, therefore, 
to bring up the information to the present date, as well as to record the 
general progress of mining and metallurgical invention, the present supple- 
ment has been written. In carrying out this work Mr. Hunt has secured 
the assistance of gentlemen practically acquainted with the various sub- 
jects on which they have written, and has also been furnished with infor- 
mation by various correspondents possessing special information upon the 
subject of arts, mines, and manufactures. Obligations are also freely 
acknowledged to such journals as the “ Engineer,” u Engineering,” the 
il Chemical News,” &c., as well as the u Transactions of the American 
Institute of Mining Engineering,” the “ Journal of the Franklin Institute,” 
and the “ Mining Journal of New York.” 
Among the more lengthy communications is a valuable article on the 
“ Manufacture of Boots and Shoes by Machinery,” by Mr. R. Meade ; this 
extends over about thirty-five pages, and is illustrated by numerous wood- 
cuts of the most modern machinery and appliances employed in that branch 
of manufacturing industry. From the statistics accompanying this article 
it appears that our largest customer for boots and shoes, of all kinds, is 
Australia, to which colony, in 1875, no less than 185,688 dozen pairs were 
exported ; while the next largest amount, namely, 94,153 dozen pairs, was 
sent to British possessions in South Africa. 
Mr. John Darlington contributes papers upon“ Ore Dressing ” and “ Rock- 
boring Machinery,” in which he has collected much valuable information 
upon a subject to which he has devoted considerable attention. Mr. G. A. 
Cowper’s articles upon “ Furnaces and Hot-blast Stoves ” are sound and
