EEPORTS OF ASTRONOMICAL OBSKRVATOHIHS. 047 



"The approximate geographical of the Observatory I'cak is: \.nurr\. 

 tilde, 121° 30' 40" W. ; latitude, 37° 21' 3" N. 



"The elevation of this point is 4,250 feet above the level of the sea. 

 The north peak, which is about three-fourths of a mile distant, is 1 Ki 

 feet higher. There is a ridge between, along which is a good trail eou- 

 nectiug the two peaks. Hie sides of the mountain, in most directions, 

 are very steep, and form an acute angle at the summit. The view from 

 the i)eaks is unobstructed in every direction, there being no higher 

 ground within a radius of 100 miles. In this connection the report of 

 Messrs. Herrmann Bros., the engineers who surveyed the road, will be 

 of interest : 



" 'The scope of the horizon i'rom .Mount Ilamilton takes in nnne ground, 

 according to Professor Whitney's judgment, tuan almost any similar 

 peak in the Uuiteu States, there being no obstru(;tion to the view from 

 any quarter. It is remarkably free from fogs and clouds, as we had 

 ample occasion to observe during our last winter's stay on the mountain 

 when locating the road. The bearings of the most notable objects are 

 as follows, the distances being taken, when out of our county, from oui 

 most reliable maps : 



Mount Loma Prieta S. 35° 5' W., IDA miles.

" 'None of these points reach the altitude of :\Iount Hamilton. Ol 

 those within a radius of 20 miles the Loma Prieta reaches 3.800 feet; 

 Thayer 3,550, and Block Mountain 2,800. All the rest are between 

 1,500 and 2,500 feet. Of the further peaks Mount Diablo is 3,850.' '*
