 miles long by 200 miles wide, embrac- 

 ing the southern half of Missouri, the 

 northern third of Kansas, and small ad-

TREASURY BUREAU OF STATISTICS 



EVERY bulletin and publication is- 

 sued by this department contains 

 information, usually unobtainable else- 

 where, on some living topic of the day. 

 Recent monographs include : 



"The Danish West Indies," a sum- 

 mar}- of facts about the three little islands 

 whose annexation to the United States 

 is now imminent. 



" Commercial Japan in 1900," a new 



edition of a monograph first published 

 in December, 1901. The work includes 

 a scholarly treatise on ' ' The develop- 

 ment of commerce in Japan, and its 

 effect on civilization in that country," 

 by Chohei Shirasu, A. M. (a native of 

 Japan). It was by this treatise that 

 Mr. Shirasu gained the degree of master 

 of arts from Columbia. 



"Great Canals of the World," con- 

 densed information and statistics in re- 

 gard to all the great artificial waterways 

 of the world — the Suez, Kaiser Wilhelm, 

 Manchester, Canadian, St. Marys Falls, 

 New York State, canals in India, Hol- 

 land, Belgium, etc. 



"Statistical Abstract of the United 

 States." Solid columns of figures are 

 not usually interesting, but the tables 

 in this report are really picturesque. 

 They are arranged in parallels in such a 

 manner as to give a graphic picture of 

 the gigantic leaps of the United States 

 in every direction during the past cen- 

 tury. This is a work that should be 

 studied by every geographer, historian, 

 teacher, or man of affairs in the United 

 States. 



ATLAS OF THE PHILIPPINES 



SOME months ago the first Philippine 

 Commission published, under the 

 auspices of the U. S. Coast and Geodetic 

 Survey, an atlas of the Philippines com- 

 prising some 30 colored maps of the 

 different islands of the archipelago. 

 The edition was, however, so small that 

 very few were fortunate enough to se- 

 cure a copy. General A. W. Greely has 

 recently published a large second edition 

 of this atlas under the auspices of the 

 Signal Office, and responsible persons 

 may obtain a copy by addressing the War 

 Department. For many years the Jesuit 

 Fathers of Manila had been preparing 

 a series of maps of the more important 

 islands. They were much handicapped 

 by an absolute want of accurate surveys, 

 but they secured all available data and
