The American Association of Variable Star Observers is the 

 present owner of the 4-inch Clark telescope originally owned by William 

 Tyler Olcott (q.v. ). According to Walter Scott Houston, the present 

 user of the telescope, on a good night it will show stars of fourteenth 

 magnitude. 



Amherst College, in Massachusetts, installed a Clark telescope of 

 7*4 inches aperture in 1854. 10 This telescope, as David Todd noted, was 

 probably the first complete equatorial built and sold by the Clarks. 11 

 Moreover, it was very likely the first telescope ever provided with a 

 clock drive regulated by a Bond spring-governor. The graduated circles, 

 12 inches in diameter, were read by verniers — the right ascension to 2 

 seconds of time, and the declination to 30 seconds of arc. The total cost 

 of the telescope was $1800. In appreciation for his work on this telescope, 

 and for his discovery of two new double stars while testing it, Amherst 

 gave Alvan Clark an honorary masters degree in 1854. 



Thirty years later Alvan Clark refigured the objective of Amherst's, 

 old transit instrument and claimed that he had done the work "by my 

 own hands entirely." 12 This must have been one of the last pieces of 

 optical work for which he was responsible. 



As mentioned above (p. 000), Carl A. R. Lundin of the Alvan Clark 

 & Sons Corporation figured the 1 8-inch object-glass for Amherst and was 

 given an honorary masters degree in 1905. 



Antioch College, in Yellow Springs, Ohio, although without an 

 observatory, in 1878 reported having a "very good" Clark refracting 

 telescope of 4.94 inches aperture, equatorially mounted on a tripod. 13 



Several times during the latter half of the 19th century lists were 

 compiled of American astronomers, observatories, and telescopes. Al- 

 though most of the instruments listed can be verified elsewhere, a few 

 cannot. In 1877 Bates College, in Lewiston, Maine, was reputed to
