196 FKOZEN WELL. 



for there was a regular depression of temperature down to 46 just as in the second well, 

 which was only 8 colder in the midst of the ice. 



Subsequent to our presentation of this subject before the American Scientific Association, 

 at Springfield, we received the following statements from Rev. J. W. Guernsey, of Green- 

 land, in New Hampshire. They awaken the inquiry whether there may not be other 

 spots, besides the frozen well, where a low temperature exists in the modified drift.

 PROF. EDWARD HITCHCOCK : 



Dear Sir, I am a native of Brandon, Vt., and have been very much interested in the 

 accounts of the " frozen well," which I visited last summer. My home was in the north- 

 east part of the town, about four miles from the well. In that vicinity are four springs- 

 familiar to me in my childhood whose waters were cold beyond any thing else of the 

 kind I ever met. They are all within the area of a mile ; all rise at the foot of gravel 

 ridges, and are very copious. The first of these is by the side of the old stage road, lead- 

 ing from Brandon to Leicester, on the farm of Dea. Asa Burnell. The second is on the 

 opposite side of the road, one-fourth of a mile south, just on the bank of Mill River, on 

 the town farm, formerly known as the Goss Tavern. The third, about three-fourths of a 

 mile to the northeast, forms the source of Spring Pond. The fourth, about one-half mile 

 northwest of the third, is on the farm formerly owned by Harvey Guernsey, and sold by 

 him to Hiram Alden who now lives near Dea. Burnell's, just by the first spring. I think 

 these springs all rise in " Drift," and it occurred to me that they might be worthy 

 of examination in connection with the well. The waters were so cold thirty-five years 

 ago, that it was one of the tests of endurance among us boys, to see who would hold a 

 finger in them the longest a trial that none of us could endure more than a few 

 seconds. 



Of the four springs I think the third was the coldest, and the fourth the next to it. On 

 visiting the neighborhood last summer, I found that the first spring had become as warm 

 as such waters usually are. Mrs. Burnell, who has resided by it for fifty years, probably, 

 remarked to me : "The spring is not what it used to be." I did not ascertain whether 

 there has been any change in the temperature of the others or not. 



Excuse the liberty I have taken in calling your attention to these springs. My only 

 apology is the interest I have in the advancement of science. 



Yours truly, 



J. W. GUERNSEY. 



Aug. 22, 1859, we visited the springs pointed out by Mr. Guernsey. The temperature 

 of No. 2, several feet from where it issues from a sand hill, was 48; that of the atmos- 

 phere 65. No. 1, at Dea. Burnell's, was 53. At Spring Pond the spring was dried up. 



Mr. Joel W. Andrews published in the Albany Atlas and Argus, some observations 

 which he made on the temperature of the water in lake Dunmore, about the first of Sep- 

 tember, 1859, showing a remarkable degree of cold. This lake lies about eight miles
