have followed this brief sketch that the study of the science of geology 

 in Canada, even though we are a comparatively new country, has not 

 by any means been neglected. Of necessity, in a country so vast, much 

 of the work for years must be largely preliminary, and the conclusions 

 reached be only generalized. The second stage has, however, at many 

 points been reached, when a more careful and detailed study of forma- 

 tions already recognized must be taken up. This will involve the 

 geological relations of our principal minerals and the peculiarities of 

 their modes of occurrence, such as our gold, silver, copper and iron, our 

 asbestus, phosphate, plumbago, manganese, natural gas and petroleum. 

 These are some of the most important economic pi-oblems in connection 

 with the science which must now be entered on by the Survey, and the 

 careful consideration and solution of which will, without doubt, consti- 

 tute factors of the utmost value as concerns the future welfare of our 



Dominion as a whole.

GRAY'S xMANCJAL OF BOTANY. 



We are pleased to announce to our botanical members the publica- 

 tion of the new (sixth) edition of Gray's Manual. It has been revised 

 and extended westward to the one hundredth meridian by Dr. Sereno 

 Watson and Prof J. M. Coulter, with 25 plates illustrating the sedges, 

 grasses, ferns, etc. 



This work, which has been anxiously looked for by all working 

 botanists, has only just, appeared, too late for review in this number of 

 the Naturalist, but a notice will appear in the next issue. In the 

 meantime, the editor would remind such of our botanists as may require 

 to get copies that they can do so through Mr. James Hope, who is a 

 member of the Club. 



FIFTH REPORT ON THE INJURIOUS INSECTS OF NEW 

 YORK, BY J. A. LINTNER. 



We have to thank Dr. Lintner for a copy of the above valuable 

 contribution to Economic Kntomology, which is a report of about 200 

 pages, illustrated by 50 figures. The chief articles are : Remedies and 

 Preventatives, The Larch Saw-fly, Injuriov;s Lepidotera, The Grain 

 Aphis, and Miscelaneous Observations. It is a mine of useful inform- 

 ation, and contains many carefully prepared and choice gems of 

 knowledge. J. F.
