A cruise was made around the entire island, but the collection was not remunerative.

The sloop was then headed to Trinidad, and along the north coast, valuable specimens were picked up.

In this same locality they struck on a reef of exquisite brain coral, with which they loaded the sloop.

Sail was then made for Port of Spain, the principal town of the island.

In going through the Dragon's Mouth, a narrow, dangerous passage between the mainland of South America and Trinidad, the Cayosa was nearly wrecked.
