34 2 Hunting Trips on the Prairie

 ley in which we had camped, through alternate pine 

 groves and open glades, until we reached the canyon, 

 and then skirted its brink for a mile or so. It was 

 a great chasm, many miles in length, as if the table-

 uninterrupted pine forest the place of all others in
