swamp, from which a small brook runs out to the 

 beach, on the north-west side of the island, where 

 there is a cove with very good anchorage, and where 

 vessels may get abundance of wood and water for 

 their use with great convenience. In the afternoon 

 I accompanied Mr. Evans and a party to the top of the

 attraction = + .040.
