I read in your valuable journal of the 30th April, present volume, a new theo.-y of earthquakes, by a Mr. Drumrnond, vherein he endeavors to show the agency of electricity in producing them, which brought to my recollection the record of a singular phenomenon, as published in a Connecticut newspaper at the time. Its location was about half a mile above the confluence of the Housatonic nd Naugatuck rivers, where the meadows on the west side of the Naugatuck extend quite up to the foot of a bluff, which bounds the meadows on the west; the bluff rises quite abrupt thirty or forty feet to the level land above. Believing it might add somewhat to the plausibility of Mr. Drummond's theory, I have taken the liberty to address this to you with a copy of the newspaper article published at the time. JEREMIAH FRENCH. Granville, Ohio, June 28th, 1853. From the Connecticut Gazette, published at Derby, February 18th, 1764 :— " On the evening of the seventh of this instant, February 1764, there was a violent storm of hail and rain; the next morning after there was observed a large breach in a hill on the west side of the old river, supposed to be occasioned by some subterraneous wind or fire; the breach !* about twenty teet deep though much caved in ; its length, one hundred and thirteen feet: about sixty rods of IU1 -was covered with gravel and sand -MZ out of the cavity, some or which was carried two hundred and fifty nine feet to the brink of the river; four trees of about a foot diameter were carried one hundred and seventy-three feet distance, and 'tis supposed by their situation, that they must have been forced up torty feet high ; some small stones about the bigness of walnuts, w*re carried with such force that they stuck fast in a green tree that stood near the cavity; a large dry log better than two feet diameter was carried up so far in the air that by the force of the fall one end of it stuck so fast in the ground that it kept the other end up. The narrowest part of the breech is about thirty feet at the surface of the ground, and the bottom of the breech is crooking, winding much like the streaks of lightning. A light was seen on the spot in the evening before the explosion. It was accompanied by a loud report, and some ios-sil substances were rejected, which were analyzed by Dr. Munson, of New Haven, and found to contain arsenic and sulphur. The above account was taken by rule by us, SILAS BALDWIN, NEHEMIAH FISHER, DAVID WOOSTER.
