The well and upper part of the well are built of masonry, and the well appears to have been sunk through a mixture of alluvial soil and limestone fragments, till a compact bed of mountain limestone was reached, having horizontal strata which could be easily worked; and the interior of the well presents the appearance of having been lined throughout with rough masonry ."
