no remarkable features. Within the same zone belong the dis- 

 turbances of India, Persia and western Europe of which records 

 are included in the accompanying- table. 



As usual the local station has freely communicated its obser- 

 vations to those engaged in seismological investigation and to 

 the press. Facsimile reproductions of the San Francisco records 

 are included in the final report of the California Earthquake 

 Commission recently published by the Carnegie Institute. It is 

 hoped that a systematic exchange of records may be inaugurated 

 between the several stations in the eastern United States and 

 Canada; the comparison and coordination of data from a number 

 of observational centers would be highly desirable. 



In reference to the accompanying records it may be stated 

 that the Albany station is equipped with two Bosch-Omori 

 horizontal pendulums. One of these is set in the meridian and 

 the other at right angles. The weight of each pendulum, includ- 

 ing arm, is 11.283 kilograms and the distance of center of gravity 

 from rotating axis is 84.6 centimeters. Their period is main- 

 tained at about 30 seconds; their multiplying ratio is 10. They 

 have no artificial damping device. Albany is situated in latitude 

 N. 42 39' 6", longitude W. 73° 45' 18". The base of the instru- 

 ments is 21 meters above sea level.
