1899] THE FRIEND OF THE FISHERMAN? 229 



the point of view of one section of the fishing community — the shrimpers. 

 The " Friend of the Fisherman " is much in evidence, and nothing is too bad 

 for those who propose fishery regulation. Mr. Dawson and Dr. Herdman come 

 in for a large share of the abuse. 



The bane of so much " popular " fisheries literature at the present day 

 (perhaps it was always so) is that the writers seem to think solely of what 

 would be best for this or that set of men with whom they happen to have 

 sympathy, instead of considering what is required in the interests of the public 

 as a whole, not this year nor next, but for years to come. Y. 



PETROLOGY FROM COOLGARDIE. 



The Geology of the Coolgardie Goldfield. By Torrington Blatchford, 

 B.A., F.G.S. Geological Survey of Western Australia, Bulletin No. 3. 

 Perth, 1899. Pp. 98 and 2 plates. 



This publication opens with a short account of the boundaries and history 

 of the Coolgardie Goldfield, together with a statement of the opinions enter- 

 tained by previous observers on the geology of the district. Then follow the 

 author's personal observations. He cites Mr. T. A. Richard's description of the 

 deposits, in which the auriferous cement, having an average thickness of 2h 

 feet, is stated to rest upon a surface of decomposed granite. A capping of 

 kaolin and sand-rock, the latter with seams of pipe-clay, rests upon the cement, 

 this capping barely exceeding the thickness of the latter. The cement is less 

 coherent than the " Banket " of South Africa. The observations of Mr. Goczel 

 on these deposits are also quoted. The Kanowna Lead is described and its 

 output given, the total yield of gold being estimated at 191,478 oz. 10 dwt. 

 22 gr. The ironstone gravel beds are next described, and then follow very 

 admirable accounts of the granite, amphibolites, diorites, andesites, and schists 

 of the district. The author is of opinion that the schists, which are horn- 

 blendic, or occasionally talcose, result from the surface weathering of amphi- 

 bolites, and he adds : " As regards the amphibolites, there is little doubt in my 

 opinion that they are so closely associated with the diorites as to be inseparable 

 from them." The question of water-supply with details of borings is next dealt 

 with, followed by important but concise descriptions of reefs. A couple of 

 pages are devoted to an account of minerals found associated with the ore- 

 bodies. Pages 51 to 78 give descriptions of the mines of the district. The 

 remainder of the work is occupied by statistics, a diagrammatic representation 

 showing the annual output of gold, and a coloured geological map of Cool- 

 gardie. Altogether this little publication is an admirable piece of work, one of 

 which any survey might be justly proud, for besides being a treatise of great 

 utility to a mining population, it is also a valuable contribution to petrology.

It should be known to zoologists that the author of this Index has for some 

 years been engaged in the compilation of an " Index Animalium." Pecuniary 

 aid has been received from the British Association and from the Zoological 

 Society of London, and we understand that nearly all zoological writings from 

 1758 to 1800 inclusive have been worked through, and that the names con- 

 tained therein have been entered in duplicate on a slip-catalogue. It is hoped
