SCIENCE 



[N. S. Vol. XXXI. No. 786 



mines of Pennsylvania in 1908 was caused by 

 a stimulated activity due to an apprehension 

 of a suspension on April 1, 1909, when the 

 wage agreements would terminate. This ac- 

 tivity continued through the first three months 

 of 1909, and the shipments in March, 1909, 

 were the largest in the history of the trade. 

 With the renewal of the wage scale in April, 

 which was in fact a continuance of the awards 

 of the anthracite strike commission for a 

 third period of three years, production fell off, 

 and the shipments of the summer months of 

 1909 were much less than in either 1907 or 

 1908. 



The Department of Superintendence of the 

 National Educational Association will meet 

 at Indianapolis on March 1, 2, 3 and 4. With 

 the department will meet the societies for the 

 Scientific Study of Education, the Society of 

 College Teachers of Education, the Confer- 

 ence of State Superintendents of Education, 

 the National Committee on Agricultural Edu- 

 cation, the Educational Press Association of 

 America, the American School Hygiene As- 

 sociation, the American Physical Education 

 Association and the Public School Physical 

 Training Society. The National Educational 

 Association will hold its annual meeting this 

 year either in San Francisco or in Boston. 



The opening of the International Scien- 

 tific Congress to be held in Buenos Aires has 

 been deferred from May 25, the original date, 

 until July or August. The following Ameri- 

 cans living in Argentina form a committee of 

 the congress representing the United States : 

 Professor Walter Gould Davis, chairman 

 (chief of the Argentine Meteorological Ser- 

 vice) ; Professor C. D. Perrine (head of the 

 Cordoba Observatory) ; Professor E. H. 

 Tucker (in charge of Carnegie Observatory, 

 San Luis), and L. G. Schultz (chief of Mag- 

 netic and Solar Physics Division, Meteorolog- 

 ical Service). 



We are requested by the director of the 

 Treptow Astronomical Observatory to print 

 the following note in the " redactionnal part " 

 of Science: "Professor Dr. A. Korn will be 

 so kind as to hold some mathematical lectures 



about : ' Freie und erzwungene Schwing- 

 ungen, eine Einfiihrung in die Theorie der 

 linearen Integralgleichungen,' in favor of the 

 Treptow-Sternwarte. The inquisitions about 

 this theory take a first place in the mathe- 

 matical inquiries of our time, and have given 

 us already well-known results in new forms, 

 as well as completely new ones. The lectures 

 will take place in the new auditory of the 

 Treptow-Sternwarte, from January 20 till 

 March 20, 1910, on every Monday and Thurs- 

 day from 6-7 hour. (One lecture is on 

 Thursday; January 20, 1910.)"
