The tree of 1876 was found by me in "the reef," or extension of the sandstone seaward, and near the low-water mark. The upper part of the stump, probably filled with sandstone, had been removed by the waves, but about 2 feet of the lower part remained. It was extracted with as much care as possible by two miners with picks and crowbar, and the disk-like fragments, into which it naturally split, were carried up to the foot of the cliff, and subsequently numbered and dissected at leisure. In the hurry of working against time to escape the tide, the men, it seems, left in the hole a portion of the lowest layer, and a frag
