interest of a voyage to the equator is to get the 

 completed view of the Milky Way." The truth 

 of this is memorable, when one thinks of the 

 successive streams of stars and the unfathomable 

 spaces, changing- night after night as the vessel 

 swings down across the line. An area of cloud 

 sailed under for twelve days in the North Pacific 

 (p. 90) is shown to have been as large as 

 Australia. It "would form a considerable feature 

 as seen from the moon. Presumably it would 

 appear from there as a great bright patch." At 

 Niagara numerous observations were made on the 

 forms of waves, and one of the fine photographic 

 illustrations is here reproduced (Fig. i). 



Dr. Cornish believes that the redistribution of load 

 through erosion of the highland-axis north of 

 Kingston caused a subsidence which propagated 

 the shocks. He also has some remarks in the next 

 chapter on earth-creep movements on the sides and 

 floor of the Panama Canal. 



It was finally Mrs. Cornish who wished, after 

 a trying illness, to revisit Panama, " where things 

 were being done which were worth doing." The 

 book is a slight one, and is in no way a record 

 of research ; but none will judge it lightly who 

 can appreciate in scientific work the stimulus of 

 complete companionship.

: formed by a hiddenjrock. Upper Rapid, Niagara. From "The Travels of Ellen Cornish. 



On p. 146 an interesting calculation is made 

 as to how long, under modern conditions, it would 

 take a traveller to see the world by davligfht, 

 and the "globe-trotter " is humbled when he learns 

 that, by doing 300 miles a day, he would require 

 136 years to appreciate the earth. 



All readers may learn something from 

 the account of the destruction of King- 

 ston, of the cameras carried out from the 

 tottering house, and then put back with a fine 

 perception when the human tragedy of the streets 

 was realised (p. 184), of the later undulations felt 

 upon a grass-lawn, and of the investigation of 

 the causes of the shock when all still lay in ruin.

presented by Messrs. Chamberlain in language 

 suitable for an elementary class. Numerous photo- 

 graphs illustrate the human aspects of the subject, 

 and these have evidently been selected so as to 

 leave natural features as much as possible in the 

 background. In fact, the book is in no sense a 

 description of the continent, but it might well be 

 read by pupils who have already become ac- 

 quainted with the great contrasts of Asiatic struc- 

 ture, from the Arabian desert to the volcanic isles 

 upon the east. This is, perhaps, implied in the 

 subtitle of the book, which conveys very little 

 geographical teaching of the kind now looked for 

 in progressive schools. We can conceive its being
