THE ALLEGHENY OBSEBVATOBT IN ITS 

 RELATION TO ASTRONOMY^ 



"When I last visited the Allegheny Ob- 

 servatory, in 1869, I found very different 

 conditions from those that prevail to-day. 

 As a boy, I had learned that Pittsburgh 

 was at the junction of the Allegheny and 

 Monongahela Rivers, and I was glad to 

 verify it by actual inspection from the 

 door of the observatory. To-day these 

 rivers are not in sight. The little thirteen- 

 inch telescope appears to have attained di- 

 mensions and to have acquired appliances 

 beyond our dreams in those days. In one 

 respect is the observatory unchanged. I 

 find a young and enthusiastic director, full 

 of new ideas and, I hope, aiming to make 

 this observatory the greatest in the world. 

 My good friend Langley was then thirty- 

 four years old. His work on the sun, con- 

 tinued through his life, was in its infancy. 

 He tried to persuade us that the smoke 

 hanging over Pittsburgh was especially ad- 

 vantageous for his line of work, since it 

 cut off the irregularities due to the heat 

 of the sun when the sky is clear. Within 

 limits, this is true. 



The early history of the Allegheny Ob- 

 servatory is unique, and in some respects 

 stormy. The first director became obsessed 

 with the idea that the telescope must be 

 preserved, but not used. This view he 

 maintained with the aid of a shotgun. He 

 became insane, and wrote a poem. Far be 

 it from me to suggest any connection be- 

 tween these two facts. In this poem, he 

 predicted that the object glass of the tele- 

 scope would be stolen. Strangely enough,
