THE APPEOACHNG TOTAL ECLIPSE OF THE 

 SUN. 



The plans of some of the priacipal pai'ties 

 from American observatories for the obser- 

 vation of the total solar eclipse occurring on 

 the morning of May 28tli are as follows : 



The arrangements by the United States 

 Naval Observatory have been made under 

 the direction of Professor S. J. Brown, the 

 Astronomical Director, and contemplate the 

 occupation of three stations, two on the 

 central line, and one near the northern limit 

 of totality. 



The first station on the central line is 

 under the immediate supervision of Profes- 

 sor A. N. Skinner, and is located at Pine- 

 hurst, N. 0. The party will comprise, in 

 addition to the five members of the Obser- 

 vatory Etas', a.ssociate members engaged in 

 spectroscopic and other researches. These 

 include Professor Ames of the Johns Hop- 

 kins University, and Doctors Dorsey, Huff 

 and Reese, and other assistants from the 

 physical laboratory of the University. In 

 the photographic work Dr. F. L. Chase, of 

 Yale University, and Mr. A. L. Colton, of 

 the University of Michigan, will take an 

 important part. The work at the station 

 will comprise the establishment of the lati- 

 tude and longitude, visual and telescopic 

 observations and drawings of the corona ; 

 photographs of the corona with the 40-foot 

 photoheliograph lens, the 7f-inch visual 

 lens belonging to the Naval Academy equa-
