the a'ame Fishes of our Rivers and Lakes. A good Act has been 

 passed by the Provincial Parliament for their protection ; and the 

 Commissioner of Crown Lands is a zealous coadjutor in this praise- 

 worthy object. It is only now necessary that the provisions of 

 the Act be faithfully and vigorously enforced — that farmers and 

 others resident on our Salmon and Trouting Streams should both 

 discourage and denounce all poaching. The inspector of the Sal- 

 mon and Trout fisheries of the Province has wisely taken steps 

 during the past season to put an end to the wholesale distruction of 

 fish out of season at their spawning beds. It is for the interest of 

 the Province and for every dealer in and lover of these noble fish 

 that these valuable products of our waters should be conserved at 

 seasons where their flesh is really almost poisonous, and they are 

 engaged in multiplying their species at so immense a ratio, as, unless 

 hindered, they are known to do. 



For a Winter evening or a Summer holiday this book will be 

 found a most pleasing companion, and we trust that it will meet 

 with many readers. A. f. k. 



The Glaciers of the Alps : being a narrative of Excursions and 

 Ascents, an Account of the Origin and Phenomena of Glaciers, 

 and an Exposition of the Physical principles to which then 

 are related. By J. Tyndall, F.R.S., Professor of Natural 

 Philosophy, Royal Institution of Great Britain, with Illustra- 

 tions. Boston : Ticknor and Fields. Montreal : B. Dawson 

 & Son. 



This Book is divided into two parts ; the j^rs^ chiefly narrative, 

 and the second chiefly scientific. In Part I. the author seeks to 

 convey some notion of the life of an Alpine explorer, and of the 

 means by which his knowledge is acquired. In Part II. an 

 attempt is made to classify such knowledge and to refer the ob- 

 served phenomena to their Physical causes. This part of the work 

 is written with an evident desire to interest intelligent persons who 

 may not possess any special scientific culture. For their sakes the 

 author dwells more fully on principles than he would have done 

 were he addressing purely scientific readers. 



The learned author was led into the investigations which this 

 book contains from the study of slaty cleavage in the Silurian 

 Rocks of Wales. The crystalline theory of Sedgwick and others 

 did not appear to him adequately to account for the phenomena.
