44 PRESIDENTIAL ADDRESS SECTION A. 



announcing Mr. Hooker's gift of money for the 100-inch mirror 

 Prof. Hale stated that "no provision has yet been made for the 

 mounting and dome. It is not known from what source funds for 

 this purpose will come, but I believe a donor will be found by the 

 time they are needed." Prof. Hale's optimism proved to be quite 

 justified. Money for the mounting and dome, and all other 

 necessary accessories, materialised in due course. 



Perrine states that the new mounting of the 36-inch Crossley 

 reflector of the Lick Observatory was only made possible through 

 the generous gifts of a lady, Miss Phoebe A. Hearst. The mirror 

 itself was made by Dr. Common, of London. It was presented to 

 the Lick Observatory by Mr. Crossley, of Halifax, England, and 

 was at that time (1900) the largest instrument of its class in 

 America. The funds for transporting the telescope and dome to 

 California and setting them up on Mount Hamilton were sub- 

 scribed by friends of the Lick Observatory, for the most part 

 citizens of California. 



Many other names might be mentioned of men and women 

 who have made magnificent gifts for the furtherance of Astronomy, 

 such as Mr. D. O. Mills, who most generously offered to provide 

 funds for constructing instruments, for defraying travelling, erect- 

 ing, and maintaining expenses, and for the salaries of the astrono- 

 mers engaged in an expedition to the Southern Hemisphere in 

 connection with the Lick Observatory. This expedition established 

 a 36| inch reflector in a suitable observatory on a hill in 

 the suburbs of Santiago, Chile, in October, 1903, and it has done 

 most valuable work. 



Miss Catherine W. Bruce, of New York, who had done so 

 much already for the advancement of Astronomy, placed 7,000 

 dollars in the hands of Prof. Barnard, in 1897, as a gift to the 

 University of Chicago, for the purpose of erecting a wide angle 

 photographic telescope and a suitable building at the Yerkes 

 Observatory. Miss Bruce had previously provided a 24-inch 

 doublet and object glass prism for the Harvard College Observa- 

 tory's southern station at Arequipa in 1896. Miss Helen E. Snow, 

 of Chicago, is another lady donor. The "Snow Horizontal Tele- 

 scope," her gift to the Yerkes Observatory in memory of her 

 father, was afterwards transferred to Mount Wilson. 



This list might be much extended, but time and space forbid. 

 It is sufficient to show one of the reasons why the United States 

 is in the forefront as regards the advancement of astronomical 

 knowledge to-day. Canada has recently completed a 72-inch 

 reflector and built the Dominion Astrophysical Observatory at 

 Victoria, British Columbia. The telescope is provided with a full 

 spectrographs equipment, and is already doing excellent work on 

 binary stars. This observatory is an offshoot from the one at 

 Ottawa, and it is interesting to learn that — as at the Lick Observa- 

 tory — it is thought worth while to devote Saturday evenings in 

 each week to the public. Visitors are then allowed to see some of 

 the glories of the heavens through this giant telescope. Some, 

 possibly, will ultimately become enthusiastic enough to take up the
