As the station at Fryeburg is 434 feet above the sea, the estimated total height of Kiarsarge would be, in one case, 3321 feet, and in the other 3315 feet.
[Prof. Airy’s table] gives 3319 and 3314 from the same data.
The instrument employed in the above measurements has been used in many other cases of altitudes from 3000 to 4000 feet. An error of about 2 per cent. in excess has been detected in those cases where the altitude has been measured by more accurate means. It seems likely that the special correction needs some slight revision.
The following measurement was made with an aneroid only 1½ inches diameter, made by Casella.
Neversink, Sullivan Co., N. Y.,
and Slide Mountain, Ulster Co.
| Time. | Bar. Readings | T. | Ht. Tab. I. | |
|---|---|---|---|---|
| Neversink. | 7 a.m. | 28.64 | 61° | 2158 |
| Fly Club Camp. | 11 ” | 27.92 | 78° | 2853 |
| Slide Mountain. | 4 p.m. | 25.87 | 69° | 4931 |
As Neversink had been satisfactorily determined to be 1350 feet above the sea, the total height of Slide Mountain is estimated from this observation to have an altitude of 4206 feet.
