Rise of Lake Erie, 119 



high, ascended from near the middle of the river, which is 

 here about 50 yards wide. The next year, a short distance 

 below Mr. Denton's, a similar phenomenon took place. The 

 well is on the margin of the river. A hole, 3 in. in diameter, 

 is perforated in a limestone rock to the depth of 400 ft. ; the 

 salt water is forced by the gas through the hole in the rock, 

 in which a tube, the upper end of which is copper, is placed, 

 50 ft. long, above the surface of the rock : at the distance of 

 45 ft. a copper faucet is inserted into the wooden tube, and 

 into another of the same kind, standing 2 ft. from the first 

 one. The salt water forced up is conducted by the copper 

 faucet into the second tube, and then descends 25 ft. to a 

 cistern holding 25,000 gallons. The water making its escape 

 from the first to the second tube, the gas passes up to the top 

 of the first tube, and, upon the application of a lighted candle, 

 instantly flashes into flame, and ascends to the height of 20 ft. 

 or 30 ft. At night the surrounding country, which is encircled 

 by high mountains on nearly three sides, exhibits the most 

 pleasing and sublime appearance. Other instances might be 

 mentioned. — J. M, . Philadelphia, Oct. 29. 1833. 



Rise of Lake Erie. — For several years past the rise of the 

 waters in the lake has made serious encroachments on its 

 southern shore in many places. For a considerable distance 

 above the mouth of Black River the bank of the lake is low 

 and without rock. Twelve years ago the bank was generally 

 sloping, with a wide beach ; now the waves beat against a 

 perpendicular bank, which, from continual abrasion, often 

 falls off. From one to three rods in width are worn away 

 annually. The cause remains unexplained. [Ohio Atlas, 

 April, 1833.) — In 1815, a newspaper at Buffalo, state of 

 New York, remarked, that " the water of Lake Erie had 

 been rising for about three years, during which time it had 

 risen nearly 3 ft." — J. M. Philadelphia, Oct. 29. 1833. 



A Notice of the Result of a Visit to the Isle of Man in search 

 of Fossils. — The total number [of species] collected from the 

 mountain limestome (at Poolvash), during a two days' stay at 

 Castleton, is fifty-three, of which only the fourteen following 

 are named in Sowerby's Mineral Conchology : — Amplexus 

 coralloides, Ammonites sphas'ricus, Orthocera undulata, i?uc- 

 cinum acutum, Pleurotomaria striata, Ampullaria /zelicoides, 

 Pileopsis tubifer, Spirifer pinguis, Prodiictus depressus and 

 Martin/; Terebratula hastata, sacchulus, pugnus, and resu- 

 pinata. Thirty-one species of the others are identical with 

 unpublished species found in the mountain limestone of York- 

 shire and Lancashire, and the remaining eight species are 

 entirely new to me.
