interior; and consequently the gases, seeking for weak spots, have burst through the earth’s crust and thus been the means of forming these minor cones that now exist. Of animal life on the mountain we saw almost nothing. That game of some sort exists is plain from the number of pitfalls we saw on the road-sides, and from the fact of our finding small nooses in the natives’ huts, such as those used for taking ground game. We heard the cries of an ape in a ravine, and saw several dull, greyish-brown birds like stonechats, but beyond these nothing. We found blueberries and blackberries at an altitude of 10,000 feet and over, and I have been able to hand over to the Pasha some specimens for his collections, the generic names of which he has kindly given me, and which are attached below. That I could not manage to reach the snow and bring back some as evidence of our work, I regret very much; but to have proceeded onwards to the mountain under the conditions in which we were situated, I felt would be worse than useless, and though all of us were keen and ready to go on, I gave the order to return. I then read off the large aneroid, and found the hand stood at 19·90. I set the index-pin directly opposite to the hand, and we started down hill. At 3 P.M. on the 7th, I reached you, it having taken four and a half hours of marching from the “Twin Cones.” I have the honour to be, &c., (Signed) W. G. STAIRS, Lieut. R.E.
