from us; and our party, with myself at the head, made for it without a moment’s delay.
The aperture, which was almost round, was about five feet in diameter; the dark passage was cut out in the live rock and lined with a coat of the eruptive matter which formerly issued from it; the interior was level with the ground outside, so that we were able to enter without difficulty. We were following a horizontal plane, when, only six paces in, our progress was interrupted by an enormous block just across our way.
