We wore ourselves out at it.
The crater of Vesuvius, as I have before remarked, is a modest pit about a thousand feet deep and three thousand in circumference; that of Kilauea is somewhat deeper, and ten miles in circumference.

But what are either of them compared to the vacant stomach of Haleakala?
I will not offer any figures of my own, but give official ones--those of Commander Wilkes, U.S.N., who surveyed it and testifies that it is twenty-seven miles in circumference! If it had a level bottom it would make a fine site for a city like London.

It must have afforded a spectacle worth contemplating in the old days when its furnaces gave full rein to their anger.
Presently vagrant white clouds came drifting along, high over the sea and the valley; then they came in couples and groups; then in imposing squadrons; gradually joining their forces, they banked themselves solidly together, a thousand feet under us, and totally shut out land and ocean -- not a vestige of anything was left in view but just a little of the rim of the crater, circling away from the pinnacle whereon we sat (for a ghostly procession of wanderers from the filmy hosts without had drifted through a chasm in the crater wall and filed round and round, and gathered and sunk and blended together till the abyss was stored to the brim with a fleecy fog).

Thus banked, motion ceased, and silence reigned.

Clear to the horizon, league on league, the snowy floor stretched without a break--not level, but in rounded folds, with shallow creases between, and with here and there stately piles of vapory architecture lifting themselves aloft out of the common plain--some near at hand, some in the middle distances, and others relieving the monotony of the remote solitudes.
