found al the present time to some extent, bul silvered glass 



has proved itself superior in many respects, and it is being 

 now generally used. 



A few years ago the Carnegie Institution of Washing- 

 ton decided to erect a (>(> inch Reflector, for a Solar Observa- 

 tory, and after a carefnl examination of many localities, 

 .Mount Wilson was selected. Its summit being nearly 6000 



feet (5886), above th :ean; located hut a short distance from 



Los Angeles, the Metropolitan City of Southern California; 

 in a district exempt from tornadoes, cyclones and hurricanes: 

 above the fogs; with an equable climate and an atmosphere 

 phenomenally free from disturbances, it offered advantages 

 not equaled by any other known place; and here has just been 

 completed the erection of the (i<> inch Reflector. 



During the last decade of the marvelous growth of Los 

 Angeles, one of her most energetic, public-spirited and pros- 

 perous citizens has been John Daggett Hooker. A man of 

 unassuming personality, identified witli all good works for the 

 advancement of the material interests of Southern California, 

 and. from a modest beginning achieving a distinguished posi- 

 tion in the mercantile world, he has been a leader among 

 those working for the higher intellectual advancement in our 

 midst, more particularly in the way of affording facilities for 

 scientific pursuits. In early youth he became interested in 

 Astronomy, and this interest has heen maintained by study 

 and observation down to the present time during a life of 

 close application to avocations which, to most persons, would 

 have proved an (dement of distraction. Several years ago he 

 purchased a Byrne five inch objective, and. fitting out the 

 entire upper story of his spacious Colonial residence on Adams 

 street as an Observatory and work room, In- not only entered 

 upon a. systematic observation of the outer worlds, hut he 

 placed all his instruments and his residence and grounds at 

 the unrestricted use and occupation of the Astronomical Sec- 

 tion of tlie Southern California Academy of Sciences, of which 

 he has heen a member almost since its inception. 



Mr. Hooker had become profoundly impressed by the work 

 with the Crossly Reflector on Mt. Hamilton and with other 

 Reflectors which had disclosed the wonders of Nebulae never 

 seen by the eye. and beyond the powers of definition by the 

 largesl Refractors, except upon the sensitive plate after lone 

 exposure, when used for photographing. 



If a sixty-inch Reflector will accomplish more than has 

 heen done by the Crossly, what will a hundred inch specidum 

 disclose.' The construction of such an instrument would 1"' 

 the work of comparatively a shorl time, and a vigorous con- 

 stitution and years hut little p;ist the middle age nave promise
