plumb down through the air, and strikes the projecting rock, 
breaking into spray. 
About two miles west of Nevada Falls is the cascade of Tu- 
sayac, about six hundred feet high, but it is very difficult of 
access. 
A few hundred yards above Lake Tocoya is Lake Tesahae, 
which has an area of about six acres, and is forty feet deep. 
No description can convey a clear idea of the great variety 
of scenery in the valley. There are a thousand nooks and cor- 
ners and woody dells, full of enchanting picturesqueness. 
The rocky cliffs take all manner of queer forms, resembling 
pyramids, castles, and domes, chimneys and spires. In one 
place there is a narrow cleft one hundred feet deep in one of 
the rocks, as though some giant had commenced to split off 
part of the mountain and had left his work unfinished. 
The river, as it meanders through the valley, is a great ad- 
dition to its beauty; and its waters, as well as those of the 
lakes, are clear as.crystal in the summer, though turbid in the 
spring. Mountain trout are found in all these streams. 
The climate of the valley is coo]. The numerous cascades 
agitate the air, and near the fall there are often gusty winds. 
There is much difference between the vegetation and tem- 
perature of the two sides of the valley; the northern side, 
where the sunshine is felt throughout the day, being much 
warmer than the shadows of the southern cliffs. Shrubs and 
flowers are in the full glory of foliage, and flower along the 
northern wall in May and June, while the same species are 
still bare or budding a mile or two to the southward ; but the 
more delicate annual shrubs are usually more healthy on the 
southern than on the northern side of the stream, because 
those in the warmer spots are stimulated to come out so early 
as to be badly nipped by the frosts, which prevail here all 
through the spring and into the summer. valley is almost 
inaccessible, on account of snow, before the middle of May, 
and the best time for a visit is in June. In the late summer 
and fall the quantity of water in these streams decreases
