Where caves are difficult of access, the Indians may place a wooden ladder, or rather, a notched tree trunk, which is the national style of staircase.

Once I saw steps cut into the soft "rock" (solidified volcanic ash), leading up to a dwelling.

There was also a kind of settee cut out of the cave-wall.
Many of the caves are remarkably symmetrical in shape, and naturally quite comfortable.

Caves may be found in the arroyos in the highlands, as well as in the barrancas.

If I were to designate a region where they are more plentiful than elsewhere, I should mention the country from Carichic towards Urique, and also to the north and west of Norogachic.
