APPENDIX. 



The Falcon Shoals, which occur at the point where the silt and other 

 fine debris carried down by the Hutt River a^:e caused to sink by coming 

 in contact with the opposing current of the tide, are nearly three-quarters 

 of a mile across. The shoals consist of sand and clay, with much decom- 

 posing vegetable material emitting H2S, and a few argillite pebbles. The 

 following living species of shell - fish and other marine organisms were
