entire circle of the horizon, have been constructed three domes, 

 in which are to be mounted modern refractors, the largest of 

 which will have an objective of 16 inches diameter. 



The pleasure of the visit to this place, to which access is 

 seldom gained by the "profanum vulgus," was greatly en- 

 hanced by a most cordial reception and the personal attendance 

 and explanations from Professor Hagen. He was greatly in- 

 terested and impressed with the accounts given him of the 

 nearly completed 60-inch Reflector and the great 100-inch 

 Hooker Reflector then in process of construction, both of which 

 were to be erected upon Mt. Wilson. 



An amusing incident at the close of this visit was the in- 

 sistence of the Professor that his visitor should subscribe his 

 name in a beautiful, gold-clasped, leather-bound volume con- 

 taining the autographs of Pope Leo XIII. and of a large num- 

 ber of the most famous scientists of modern times, who have 

 visited this place; and there is his name as Secretary of the 

 Astronomical Section of the Southern California Academy of 



Sciences. HOLDRIDGE OZRO COLLINS.
