TWIN ISLANDS CAPE ST. MICHAEL. 667 



Twin islands, north-northwestward about 1 mile from Ship Har- 

 bor head, are two islands separated by a narrow channel ; the eastern 

 island rises in two conical grass-covered mounds to the height of 

 about 60 feet; the western is a narrow black rock, about 400 yards 

 long and 32 feet high. 



A shoal, with 5^ fathoms of water over it, bears 292°, distant 550 

 yards from the northern point of the western Twin island, and lies in 

 mid-channel of the northern entrance to Occasional harbor. 



Occasional harbor, the entrance to which is between White point 

 on the southern side and Northern head, lying northwestward, distant 

 ^ mile from the western Twin island, on the northern side, extends 

 southwestward 5h miles from Twin islands, and is clear of shoals. 

 For 3 miles within the entrance the average width of the harbor is 

 700 yards, and the water is too deep for anchorage ; it then opens into 

 Delaney cove on the southern side and French and Trout coves on 

 the northern side. Delaney cove, extending I mile to the eastward, is 

 separated from the head of Ship harbor by a neck of land 700 yards 

 across; rocks lie some 80 yards off the northern point of this cove. 

 French and Trout coves each extend 500 yards to the northward, and 

 vessels requiring to dry fish haul close to the shore in either cove, but 

 the water is shoal for 100 yards off the point separating them. 



Southwestward of Trout cove a projecting point from the northern 

 shore, with rocks extending 150 yards from it, narrows the harbor 

 to 300 yards. Arch cove, westward of this projection, is a secure 

 anchorage 800 yards across, with 5 to 12 fathoms of water. Mercer 

 island, 3 feet high, is 100 yards off the southern shore southwestward 

 of the anchorage and marks the eastern limit of the shoal water, 

 which bars, except to small craft, the entrance to a basin about | mile 

 in length, with depths of 6 to 14 fathoms. 



Anchorage can be obtained in the harbor off the entrance to French 

 cove; in Delaney cove in 10 fathoms; or southward of the point sep- 

 arating French and Trout coves, in 11 to 14 fathoms water. 



Water can be taken from many places along the shores, but the 

 most convenient place is on the shore southward of Arch cove. Fire- 

 wood is abundant. 



Tides. — It is high water, full and change, in Occasional harbor at 

 6h. 48m. ; springs rise 5 feet, neaps 3| feet. 



Cape St. Michael is the eastern end of the promontory separating 

 Occasional harbor from St. Michael bay, and it extends from North- 

 ern head northwestward 2^ miles to First point. The coast is steep 

 and bold-to; Hole-in-the-wall, a remarkable ridge with a hole 

 through, lies north-northwestward 800 yards from Northern head, 

 and Main cape, which terminates in a low peninsula, is 600 yards 

 farther northwestward.
