REVIEWS. 



Mr. Jarvis, in his Report on the Caughnawaga 



Canal, places the dimensions of the locks at 230 x 36 x 10ft. 



10ft. depth of water on sills, 

 Mr. "Walter Shanly, in his Ottawa Report, takes 



the "Iowa" as a representative propeller, 



and proposes 250 x 50 x 10ft. 



Mr. T. C. Clarke in his Report upon this Survey, 



names 250 x 45 x 12fc. 



Mr. Kivas Tully, in his Georgian Bay Report, 



advocates the recognition of 1000-ton propel- 

 lers, and accordingly specifies 265 x 65 x 12ft. 



"Be the dimensions what they may, the necessity must be recognized, that two 

 vessels navigating the Canal, may pass at any part of it : hence the width at the 

 bottom must be at least 100 feet. The extent of the improvement will be argued, 

 under the general head of the development of the Saint Lawrence navigation, 

 necessary to command the trade of the Western Lakes. For the moment, all that 

 need be said is, that the enlargement of the Welland is a mere question of extent 

 and finance." 



After thus discussing our existing canals, Mr. Kingsford devotes 

 a large portion of his work to a consideration of the various schemes 

 projected within the last few years for the improvement or extension 

 of our canal navigation, generally. These schemes comprise : (1) 

 The Ottawa and Erench Eiver project ; (2) the Chats Canal ; (3) 

 the so-called "lateral cut" of the Welland to the town of Niagara ; 

 (4) the Toronto and Georgian Bay Canal ; (5) the Georgian Bay 

 Canal via Lakes Simcoe and Skugog ; and (6) the canal project by 

 the Eiver Trent. To these schemes Mr. Kingsford opposes many 

 strong and apparently well-grounded arguments : holding that not 

 one of these projects, if carried out, would have any extended 

 influence on the trade of the Province. If we cannot accord to 

 him our entire support on this question, we may at least admit that 

 the deepening and general enlargement of our present canals should 

 of necessity precede the execution of new and, in a measure, experi- 

 mental projects. In a succeeding chapter, much valuable information 

 is given on the present condition and future prospects of the Erie 

 Canal, considered, more especially, in its opposing relations to the 

 St. Lawrence route. The canal question in its more p\irely financial 

 aspect is then discussed ; and the subject of " Tolls, Eevenue, and 

 Tonnage" is illustrated by a series of tables, compiled, apparently 

 with great care, from various official records. Finally, Mr. Kings- 

 ford concludes his book by a general review of our canal policy in all
