(i) Miscellaneous: The only instrument at present used in the "Ob- 

 servatory" is a 4-inch achromatic telescope, which was purchased by the 

 board of education, about nine years ago, for the use of students and 

 teachers in the high school. It was manufactured by Pike, the New 

 York optician, and is mounted upon a portable tripod stand, provided 

 with all the necessary adjustments. For the general observations of 

 astronomy, it is regarded as one of the best telescopes in this State. 

 The two celestial eye-pieces belonging to the instrument disappeared 

 mysteriously about three years ago, having been stolen from the case 

 in which they were kept; and as they have not since been replaced, the 

 telescope has remained in a crippled condition without them. But some 

 new eye-pieces are to be ordered soon, with powers varying from 45 to 

 275, together with colored eye-screens for observing the sun, and a comet 

 eye-piece, with large field and low power. A terrestrial eye-piece is at 

 present being employed, with a power of about 75 diameters; but the 

 telescope has been used to good advantage for observations of the moon, 

 Jupiter's satellites, and star-clusters. 



III. Observations during the past year: 



A continual watch for meteors was made throughout the night of 

 August 10, and a large number were observed between the hours often 

 and eleven o'clock in the evening, but about midnight the moon made 

 its appearance, and being near the " radiant" in Perseus, pre vented any
