Cultch

Stones, ballast, old pieces of earthenware, water-pipes, and old shells form excellent cultch, and, if any of these are scattered about the beds, a good catch may be confidently expected.

The cultch at first floats in the water for ten days or more; then it attaches itself to some piece of gravel or shell. In many places the force of tidal currents, or the lack of protection from winds, results in the loss of the cultch before it secures an anchor; but the waters of Quilcene Bay recede without greatly endangering the cultch during its floating, unanchored period.
