ROCK CARVINGS IN MINNESOTA.

Mr. P. W. Norris has discovered large numbers of pecked totemic characters on the horizontal face of the ledges of rock at Pipe Stone Quarry, Minnesota, of which he has presented copies. The custom prevailed, it is stated, for each Indian who gathered stone (Catlinite) for pipes to inscribe his totem upon the rock before venturing to quarry upon this ground. Some of the cliffs in the immediate vicinity were of too hard a nature to admit of pecking or scratching, and upon these the characters were placed in colors.
