A NATURAL WALL OF MARBLE. 35

scognised by our guide, such as bunches of grass tied up 
1d made to point in particular directions, and were looked 
on as conclusive evidence of the activity and watchfulness 
‘our hidden, but probably ever-present, enemies. Game 
as abundant: two kinds of quail, black and white-tailed 
er, bears, beavers, squirrels, and hares innumerable. Ex- 
msive fires had burnt down the bushes and laid bare large 
facts of land all along the base of the mountains. 
i While taking advantage of the delay, which the diffi- 
fialties of the country necessitated, to enjoy a little deer- 
alking and grouse-shooting, Lieutenant Lawson (who 
mmanded our escort) and myself were attracted during our 
mbles by a curious wall of rock which fringed, like a 
gap-dyke, the summit of a rather lofty range of foot-hills. 
reaching the top we found that it consisted of a thick 
of marble, which had been tilted up vertically 
the height of from 7 to 20 feet above the ground, and 
at it extended for miles both ways along the hill-tops. 
his wall was beautifully variegated with white, grey, and 
id marbles, and presented the finest as well as the most 
ngular exposure of the kind I have ever seen. In many 
aces through the mountains we found quartz ledges, giving 
od indications of gold; and near the marble wall a vein of 
lena cropped out, of considerable width. Over this vein I 
» aot a new and beautiful species of mountain grouse. 
i our days were occupied in trying to find a good pass 
rough the range, but our efforts were useless. We found, 
fer surveying to the summit of the ridge which skirted the — 
Se of the mountains, that it was 1,208 feet higher than Ojo 
iente, twenty-three miles distant, and that the average 
- for the last three miles had exceeded 160 feet per
