Captain Thomas thus describes his descent into and exploration of this
earth-house:--"An irregular hole was pointed out by the little lassie
before alluded to, and some of my party quickly disappeared below
ground. As they did not immediately return, I thought it was time to
follow, and squeezing through the ruinated entrance (_a_), I entered the
usual kind of gallery, which descended into the ground at a sharp angle.
