Instead of one colored illustration, this year the volume has four the bird's- 

 eye view of the proposed Nicaragua Canal, and maps of the Territories (soon to 

 be States) of Montana, Washington, and the Dakotas, though the congressional 

 action in regard to these Territories took place in 1889. The three steel por- 

 traits include the new President and Chief-Justice of the United States and the 

 young Emperor of Germany. Among the other illustrations of special interest 

 are the new bridge over Harlem river, the moving of Brighton Beach Hotel, 

 the appearance of New York streets after the great blizzard, the Eiffel Tower, 

 the Lick Observatory, the maps of Southern Africa and the Samoan Islands, the 

 new United States cruisers, the series showing evolution of the railway-car, the 

 map of Mars as seen through the great telescope, and the numerous fine portraits 

 in the text, including those of Vice-President Morton and Gen. Schofield.
