bank, we arrived, by a little circuit, at the foot of the upper fall. 
The water descends from a projecting ledge in a wide sheet ; 
and it appeared that a traveller might, in any season, walk be- 
tween the fall and the rock, without being wetted by its waters. 
We now followed the bank, and in a short time, by a very steep 
descent, reached the top of the great fall. On the left side, 
looking down the stream projects a rock, over one part of whicb 
the torrent precipitates itself. From this spot, the valley, and 
the trees at the foot of the fall, are visible ; but that point where 
the water reaches the ground cannot be seen. The stream had 
worn a channel in the limestone rock for some distance above 
the fall ; and after being precipitated over the edge, at about 
forty feet below, strikes very obliquely against a rock on the 
left side. This gives it an inclination in its downward course, 
which makes it appear to be slightly convex towards the upper 
part of the valley, unless there is a current of air along it, or 
other causes intervene to prevent it. The following are the ob- 
servations from which the heights were deduced :

From these I have deduced, by calculating the observations^ 
according to M. Ramond’s method, the following heights;
