Miss Elma Loines gave the Maria Mitchell Observatory (q.v.) an 

 8-inch refractor, made by the Clarks in 1871, which her father had used 

 in his observatory at Bolton Landing, Lake George, New York. 153 



Rev. R. E. Lowe, in England, purchased an 8}4-inch Clark equatorial 

 from Dawes (q.v.) in 1864 and later sold it to J. M. Wilson for use at 

 Rugby School (q.v.). Lowe had Thomas Cooke make a new drive 

 mechanism for the telescope and then wrote sadly: "And perfect as one 

 has been taught to consider Cooke's mountings to be, this Alvan Clarke 

 clockwork was pronounced to take decided precedence over that by which 

 the York maker replaced it." 154 



Thaddeus S. C. Lowe built the Lowe Observatory on Echo Moun- 

 tain, at the head of the Mount Lowe cable railway, in 1 894. Other attrac- 

 tions on this California mountain included several hotels and pleasure 

 resorts. Lowe invited Lewis Swift (q.v.) to direct the new observatory, 

 and to bring with him his 1 6-inch Clark equatorial refractor which had 

 been installed in the Warner Observatory (q.v.). 155 The Lowe Observa- 

 tory was in existence until 1 928, when the dome was blown off by an extra 

 strong wind. In 1941 the Pacific Electric Railway Company, which had 

 acquired title to the Mount Lowe properties, sold the telescope to the Uni- 

 versity of Santa Clara (q.v.). 



Alvan Graham Clark worked closely with Percival Lowell in planning 

 and equipping the Lowell Observatory. Before the Flagstaff, Arizona, 

 site had been chosen, Lowell and his assistants used portable Clark equa- 

 torials of 4 and 6 inches aperture to test atmospheric conditions at other 

 possible sites around the world ; the definition of the 6-inch telescope was 

 said to be "unsurpassed in beauty." 156 



The first large telescope erected at Lowell was a composite instrument. 

 The equatorial mount, borrowed from Harvard (q.v. ) , had been built by 

 the Clarks to carry the 13-inch Boyden photographic refractor. At Lowell 

 it was adapted to carry a refracting telescope at either end of the declina- 

 tion axis: an 18-inch Brashear and a 12-inch Clark. The 12-inch, re-
