chief of an expedition to determine whether 

 Asia and America were connected by land. 

 The expedition went overland through Sibe- 

 ria to Kamchatka, where ships were built 

 and the explorations begun. Bering reached 

 the strait that bears his name, and thus 

 proved that Asia and America were sepa- 

 rated by water. Soon after his return he 

 proposed a second expedition to chart the 

 northwestern coast of America, then an un- 

 known land, and the northern coast of Sibe- 

 ria. This should lead to the establishment 

 of trade with the American colonies, and 

 also make known a way by water from Rus- 

 sia ai'ound to Japan. Bering reached the 

 coast of Alaska in 1741, and died on the 

 way back. For a long time jealousy dis- 

 credited his results, and the chief object of 

 the present volume is to establish the value 

 of his discoveries. The book also tells the 

 story of the obstacles which he overcame in 

 his expeditions. It is accompanied by two 

 folded maps, and has an introduction by 

 Lieutenant Frederick Schwatka. 



The literature of cycling has been in- 

 creased by a book bearing the title Cycling 

 Art, Energy, and Locomotion, written by Rob- 

 ert P. Scott (J. B. Lippincott Company, $2). 

 It is largely devoted to explaining the me- 

 chanical principles involved in the action of 

 the cranks, wheels, springs, bearings, gears, 

 etc. It includes also brief discussions of 

 the injuries charged against cycling, the bi- 

 cycle for ladies, English and American work- 

 manship in cycles, aluminum in cycle con- 

 struction, and the application of steam and 

 electricity to cycles. A second part of the 

 volume comprises extracts from the patent 

 specifications of a large number of veloci- 

 pedes, cycles, and nondescript vehicles, with 

 the inventors' drawings of the machines and 

 riders, and humorous comments by the au- 

 thor. Many of these machines are astonish- 

 ing contrivances, and perhaps none more so 

 than the flying-machine, patented March 5, 

 1889, which is introduced at the end.
