The Citizen's Atlas. Edited . by J. G. Bartholomew, LL.D. (J.
Bartholomew'and Co. 25s. net.)—The editor gives us, by way of Introduction, a useful essay entitled "The Progress of Geography." We have on the first page a striking illtistration in the shape of two Contrasted representations of the world of geography as it was in 1800 and in 1010. The " black," i.e., unexplored area in the eiVlier covers 'about fear-fifths of the whole ; in the later it is reduced to two patches at the North and the South Pole. Then there- is a " red " area, showing the regions which can be reached in a three weeks' journey. In 1800 this was limited to Europe it now covers in the Northern Hemisphere about five times as much and, is to be seen oven in the Southern. The British Empire has grown in the same period from 1,600,000 square miles to 11,450,000,. and its trade from 480,000,000 to 42,204,000,000, the halfway house of 1850 showing £224,000,000. The maps show an improved sense of proportion. France is not now crowded into a single page, but occupies four with its two sections, The colonial maps also show more detail.
