water which it conveys, the commercial advantages which it fur- 

 nishes, and the grandeur of its disruption in the spring, are all 

 suitable accompaniments of so sublime and glorious a scene.

GEDDES, James. Observations on the geological features of the south 

 side of the Ontario valley in a letter to F. Romeyn Beck. (Am. jour, 

 of sci., Oct. 1826, 11:213-218.) 



Observations on the formation, contour and geological history of the 

 Niagara gorge. 



1827 



Hall, Capt. BASIL. Notice of the pressure of the atmosphere, etc., 

 within the cataract of Niagara. (Jour. Frank, inst. 1827. 5:48-51.) 



A letter written to Professor Silliman under date of October 29, 1827, 

 and apparently taken from Professor Silliman's journal. The author, a 

 captain in the Royal Navy and F. R. S. describes his experiment to ascer- 

 tain the barometric pressure at the Falls, and feels " quite confident, of 

 having succeeded in ascertaining, that there was no sensible difference 

 between the elasticity of the air at the station on the outside of the falls, 

 and at that, one hundred and fifty-three feet within them." 



1829 



BAKEWELL, ROBERT, Jr. On the Falls of Niagara and on the 

 physical structure of the adjacent country. (Loudon's mag. of nat. hist., 

 Jan. 1830. 3:117-130.) 



Besides the description of the country around the Falls, there is a gen- 

 eral account of the cataract itself, with an account of the author's first 

 view and what he considers the grandest view — from the foot of the lime- 

 stone rock on the Canadian side. He also gives his opinions on the reces- 

 sion of the Falls, the formation of the different strata, the origin of the 

 Falls at Queenstown, and his observation on the gradual cutting through 

 the rock, discernible at the time of his visit, which was made in 1829. 



1831 



FEATHERSTONEHAUGH, G. W. On the ancient drainage of North 

 America, and the origin of the cataract of Niagara. (Mon. Am. jour, 

 of geol. and nat. sci., July 1831. 1 :13— 21.) 



A flat view of Niagara taken from a model by Mr. George Catlin, 

 " a very ingenious artist." The account is excellent considering the date.
