THE POPULAR SCIENCE MONTHLY 
FOR 1898. . 
VIDENCE of the increasing influence of science in all fields of human 
activity is apparent on every hand. The farmer is looking to it for better 
methods in cultivation and the raising of stock. The manufacturer asks of it 
cheapened processes to meet ever sharper competition. The economist seeks in 
it a firm basis for his policy. The doctor and sanitarian call upon it for a 
more perfect equipment for their struggles with disease. The educator consults 
it with reference to more rational methods of instruction. Literature, politics, 
and the Church are among its most interested listeners, since it is testing their 
respective claims in a way that compels attention. 
The Popular Science Monthly has long borne a leading part in making the 
general reader acquainted with this great and rapidly-growing department of 
human knowledge. It has aimed to do this with perfect fairness, and with all 
the tolerance of earnest beliefs that is consistent with a fearless adherence to 
the truth, and the same attitude will be maintained in the future. 
SCIENCE AT THE WORLD'S FAIR.—Among the special features of 
this standard magazine for the coming year will be accounts by competent special- 
ists of the present standing of the several departments of science as exhibited at 
the Columbian Exhibition in Chicago. The marvels of Electricity to be dis- 
played there will be described and explained by Mr. CHARLES M. LUNGREN. 
Large provision has been made for the exhibit of Anthropology, and this 
department will be carefully treated by Prof. FREDERICK STARR, of the Chicago 
University. Mr. Bensamrn Reece will treat of the application of science in 
the vast interests of Transportation, and the scope and significance of the 
exhibits in other departments will be set forth by able hands. 
THE DEVELOPMENT OF AMERICAN INDUSTRIES SINCE 
COLUMBUS.—The splendid series of illustrated articles under the above title 
will be continued, ahd probably brought to a close in the coming year. Among 
the subjects that remain to be treated are Glass, Silk, Paper, Agricultural 
Machinery, and Ship-building.

been in the habit of addressing the readers of the Monthly.
