(c) Measurements of the outgoing- radiation from the earth dur- 

 ing- totality. 



Similar observations for comparison were also planned for another

 335 cm. (11 feet) focus and 7.5 cm. (3 inches) aperture. 



(3) Observations of the times of contact, and visual observations 

 of the phenomena. 



FIELD CONDITIONS 



The station chosen was on the central eclipse line, about midway 

 between the towns of Lakin and Hartland, Kansas, both of which 

 are on the main line of the Santa Fe Railroad. Computations by 

 Rev. Woodman gave the location of the station as follows : 



Latitude 37 53' 4': 2 N, 



Longitude 101 17' 5 1 '-' 3 W. 



The altitude at this place is 900 meters ( 3,000 feet) above sea level, 

 with a mean barometer of 6j cm. (26.7 inches) . There is little rain- 

 fall, and the land, which is flat and bears few large trees, is chiefly 

 given to the cultivation of alfalfa, watered artificially. 



Mr. Aldrich and Mr. Kramer arrived at Hartland on Monday 

 morning, June 3, and were joined there by Rev. Woodman. An 

 eclipse party from the Department of Terrestrial Magnetism of the 

 Carnegie Institution of Washington, under the direction of Dr. S. J. 

 Mauchly, had chosen the same location and were already on the 

 ground when the Smithsonian party arrived. This fact proved of 

 decided value to our expedition, for, being familiar with local condi- 

 tions, Dr. Mauchly and his party gave us valuable suggestions and 

 assistance. Their interest and help is gratefully acknowledged. 



Within a few hundred feet of the station of the Department of 

 Terrestrial Magnetism, and in the same alfalfa field, there stood an 

 unused barn which immediately suggested itself as an excellent 

 windshield for our instruments. Permission to use the barn was 

 given us by Mr. Jacob M. Hoss, lessee of the property. The thanks 

 of the Institution are due him for granting this privilege entirely 

 without charge. It is pleasant to record the universal interest and 

 disposition to help among all with whom we came in contact. 

 Especially we wish to acknowledge the kindness of Mr. and Mrs. 

 P. C. Pittenger, the nearest neighbors, for furnishing two of our 

 party room and board at great inconvenience to themselves.
