THE ASTRONOMICAL AND ASTROPHYSICAL 



SOCIETY OF AMERICA 



I 



The eighth annual meeting was held 

 December 27 to 29, 1906, at Columbia Uni- 

 versity, New York. About sixty-five mem- 

 bers attended and thirty-two papers were 

 presented. 



President Pickering, on taking the chair, 

 discussed three lines of work which he be- 

 lieved the society should pursue. First, by 

 cooperation to carry out some great routine 

 investigation too extensive to be under- 

 taken by a single observatory. The best 

 example of this was the accurate deter- 

 mination of the positions of the northern 

 stars, by European and American observa- 

 tories, under the direction of the Astro- 

 nomische Gesellschaft. Second, to bring 

 together socially astronomers from all parts 

 of the country, especially the older and 

 younger men. The latter may think the 

 work of the older men out of date, but they 

 may find the experience of the older men 

 and their personal acquaintance with the 

 eminent men of still earlier date of great 

 assistance. The older men have much to 

 learn regarding new methods, and the ex- 

 tensive appliances at their command may 

 often be employed to much greater advan-
