Let go the anchor in eighteen fathoms water about half a mile from the Brig Rock. Saw two other rocks with heavy sea breaking over them, which are not on the charts.
At daylight strong wind came in with heavy sea rolling in from W. Hove short when the cable parted at thirty fathoms. Made sail and ran into Milford Haven and anchored again in Freshwater Basin.
Some of my passengers who came overland from Martin's Bay, saw part of a wreck painted light stone color, also a square, log of American timber.
Sailed from Milford Haven on Saturday, 30th May, and arrived in Marten's Bay on 1st June.
Found seven fathoms at low water, and went in on the 2nd. Sailed up the river about four miles, and then came into a lake about ten miles long and four miles broad.
The passengers took the boat and went up the lake- and found another river, and beyond that another lake running N.N.E., went to the head of the lake and could get no further for SNOW.
The passengers returned June 20th, and the ship came down the lake to the mouth of the river, but finding the sea running too high over the bar, did not get out to sea till July 8th, when we left with a strong gale from the N.W., at night the gale increased to a HURRICANE.
