Report on the Building and Ornamental Stones of Canada. 

 Vol. III. Province of Quebec ; by Wm. A. Parks. Pp. xiv, 

 304 ; 52 pis., 12 figs. — The building stones of Quebec, thus far 

 developed, consist largely of excellent limestones, with decorative 

 and structural marbles ; also granites, while slate is quarried to a 

 limited extent. The volume is profusely illustrated and the 

 colored plates are of unusual excellence. The same subject is dis- 

 cussed in Vol. I for the province of Ontario, and for the Maritime 

 Provinces in Volume II. 



Gypsum in Canada ; its occurrence, exploitation, and 

 technology ; by L. H. Cole. Pp. x, 256, xi ; 30 pis , 27 figs., 6 

 maps. Gypsum is one of the more important of the mineral 

 products of Canada, and is particularly developed in Nova Scotia, 

 where the beds have in some cases a thickness of 100 feet. The 

 occurrences in New Brunswick are also of importance. The total 

 production in 1913 was valued at nearly $1,500,000. 



A General Summary of the Mineral Production of Canada dur- 

 ing the calendar year 1913 ; by JohnMcLeish. Pp. 50. Special 

 publications on the production of iron and steel ; coal and coke ; 

 lime, clay, and structural materials are given by the same writer. 

 C. T. Cartwright reports on the useful metals. It is to be noted 

 that in 1913 the total value of mineral products was upwards of 

 $145,600,000, having increased 8 per cent from the previous year, 

 and about three times since 1899. An increase is shown in almost 

 ail the metallic and non-metallic products, except in copper, 

 where there was a falling off of about $1,000,000. 



A Preliminary Report for 1914 has also been prepared by Mr. 

 McLeish. The figures here given show the effect of the wide- 

 spread industrial depression. The total value of products is only 

 $128,500,000 ; in metallic products there was a decrease of 11 per 

 cent as compared with 1913 and in non-metallic products a 

 decrease of 12 per cent. 



2. State Geological Survey of Illinois. Bulletin No. 28, Oil 

 and Gas in Bond, Macoupin, and Montgomery Counties, Illinois ; 

 by Raymond S. Blatchlet. Pp. 51, pis. I-IV, one fig. — A 

 detailed study of the stratigraphy and structure of a portion of 

 Western Illinois suggests that prospecting for oil and gas may be 

 profitably undertaken in this region. h. e. g. 



3. Further Notes on Meteor Crater, Arizona ; by D. M. 

 Barringer. — A notice of Mr. Barringer's investigations of the 

 remarkable " Meteor Crater " in Coconino county, Arizona, was ' 

 given in an earlier number of this Journal (vol. xxx, p. 427, 1910). 

 A supplementary paper has recently appeared in the Proceedings 

 of the Academy of Natural Sciences of Philadelphia (1914, pp. 

 556-565). This is accompanied by three plates, giving a map of
