Further down Total Depravity Passage we were not urged to go, because at
that season of the year it is wet and difficult, without any sufficient
promise of a brilliant compensation for the achievement of such a
journey. But the Spring of Youth Room, or as it is generally called, the

and the attraction located at the most distant limit.

rock masses without obliterating evidences of original design.

A glance at the map shows the sudden breaking off of the various
passages represented; the end, however, is not of the passages

the Mother Hubbard Room, and spreading out from this is the corridor, a
room about one hundred and twenty-five feet long and seventy-five feet
