Account of the Great Waterfalls of Rewali. 87 
is the quantity of water which rushes down, and the last spray 
that arises from the pool, which render it, especially at this sea- 
son of the year, a fall of more interest and grandeur than the 
others. The one to the left flows over natural steps, as it 
were, hewn in the rock, and is a pleasing contrast to the impe- 
tuous torrent on the right. W e threw a deceased dog over the 
larger fall, which went down headlong in capital style, and 
seemed when it reached the surface of the bason uninjured ; 
but no sooner had this been effected, than it instantaneously dis- 
appeared from our view, and though we remained some hours 
afterwards sitting on the top of the crag, it never again rose. 
The violence and rapidity of the current must have carried it 
underneath, where it no doubt sooner or later was swallowed 
and devoured by alligators. 
A curious phenomenon, not only with regard to this, but also 
to the others, is, that the water, when it reaches the bottom, 
assumes a dirty green appearance , similar to the salt-water near 
the shore, and the taste becomes bad and sour. How this is to 
be accounted for, I am perfectly ignorant, and should feel 
obliged to some of your naturalist correspondents to give a sa- 
tisfactory explanation ; but it is to be kept in mind, that the 
very great depth of the pools, which are said to be unfathomable, 
does not cause this colour ; for that which issues out of the basons, 
and runs over rocks, so shallow as not to come much above the 
ancle, has the same green aspect. The glen of the Touse is 
narrow and perpendicular, and does not admit of a person ap- 
proaching immediately under the fall, as we did at the rest, on 
account of the water extending about 40 yards down the dell, 
from side to side of the descent, and the steepness of the rocks 
prevents there being a passage on either bank. 
I shall conclude this letter, by observing, that we wore all 
most highly gratified by the sight of those superb natural curio- 
sities, which are the highest waterfalls known in the world, the 
highest Fall of Niagara being only 168 feet, and thus making 
the Fall of Chechai 200 feet greater than that which was once 
supposed to be the most lofty in the universe ! 
It may be said, however, that the river St Lawrence being 
a very large and noble stream, the fall must of course be far 
more magnificent and grand than any of those which I have at-
