The Thrumcap, 142 miles southward of Round Porcupine Island, is a round rocky island, with a clump of trees in the center.

Newport Ledge, 400 yards from shore, midway between the Thrumcap and Schooner Head, is bare at extreme low water and marked on its eastern side by a black buoy. The bottom inside of it is broken, and should not be crossed by vessels.

Egg Rock is described on page 93.

Schooner Head and Great Head are prominent rocky headlands, and Great Head is distinguished by an observation tower on the top.

Schooner Ledge, 350 yards from shore, midway between Schooner Head and Great Head, is bare 4 feet (1.2 m.) at low water and marked by a black buoy 300 yards eastward of it.

Newport Cove, a small cove westward of Great Head, is exposed southward, has poor holding ground and is never used as an anchorage. There is a bare rock off the entrance.

Mount Desert Island ; stone tower on Great Head bearing northwestward

Otter Cliff Ledge, 400 yards eastward of Otter Creek Point, is bare at half tide and marked by a black bell buoy. A circular stone observation tower has been built on the summit of Otter Cliff. This tower resembles a lighthouse.

Otter Cove, a long cove making northward of the west side of Otter Creek Point, has deep water in the entrance and is bare for 38 mile from the head. It is exposed southward and not used as an anchorage. There is a naval radiocompass station about 14 mile northward from Otter Cliff. The call letters are NQC. The radio towers and a water tank are prominent. The other coves and islands are described under “ South West Harbor and approaches."

SOUTH WEST HARBOR AND APPROACHES

South West Harbor, Somes Sound, North East Harbor, and several other coves lie in the southeast side of Mount Desert Island, inside a large group of islands and shoals. These waters are the approaches to several important villages and summer resorts, and are

frequented by passenger steamers, fishing boats, and many pleasure craft. South West Harbor is also extensively used as a harbor of refuge. They can be approached through the channels on either side of Sutton Island or through Western Way.

Baker Island, the most southeasterly of the islands in this vicinity, is wooded and marked in the center by Baker Island Lighthouse. It is surrounded by ledges, bare and submerged, and should be given a berth of at least 38 mile. The Thumper is a ledge, bare at low water, lying 300 yards southward of the island. Another ledge, partly bare at low water, lies 1/4 to 3/8 mile off the southwest side.

Baker Island Lighthouse is a white tower connected with dwelling. The light is fixed white, with a white flash of 5:seconds' duration every 90 seconds, 105 feet (32 m.) above the water, and visible 16 miles.

Little Cranberry Island is low and wooded, and has no promi: nent marks visible from southward or eastward. Islesford is a post village on the northwest end. There is a large wharf and several fish houses. The passage between Little Cranberry and Great Cranberry Islands is used at any stage of the tide by small local craft, but it has many unmarked ledges and should not be used by strangers.

Cranberry Harbor is southward of Sutton Island between Little Cranberry and Great Cranberry Islands. It is frequented by small local vessels, and coasting vessels sometimes anchor here, but South West Harbor is a much better anchorage. The usual anchorage is in 14 to 20 feet (4.3 to 6.1 m.) in the middle of the harbor with the wharves at Islesford bearing about 50° true (ENE. mag.), taking care to keep well clear of the black buoy on the end of the ledge which extends 350 yards westward from the east side at the entrance.

Great Cranberry Island is wooded and has no prominent marks visible from southward. Cranberry Isles is a post village on the island. There are two wharves in Spurling Cove on the north side, a fish wharf on Long Point at the northeast end, and a wharf, bare at low water, in The Pool, a shoal cove in the eastern side, obstructed by many reefs.

South Bunker Ledge, in the southern approach to Western Way, is bare 4 feet (1.2 m.) at low water and marked by a spindle.

The Nubble is a dangerous reef, mostly bare at low water and having a few rocks bare at high water, extending 12 mile southeastward from Mount Desert Island. It is marked off its end by a black bell buoy.

Western Way, between the western side of Great Cranberry Island and Mount Desert Island, is a frequently used passage for vessels bound to South West Harbor and vicinity, and is generally used by all small vessels bound between points westward and any point in Frenchman Bay. The channel is buoyed and the least depth is 14 feet (4.3 m.) on a bar at the northern end, but there are unmarked spots of 10 to 12 feet close to the sailing lines, and the passage should not be used by strangers with a greater draft than 10 feet (3.0 m.).

South West Harbor (chart 306) is the most important harbor on the south side of Mount Desert Ísland. It is an excellent, wellsheltered anchorage in 2 to 8 fathoms (3.7 to 14.6 m.), and can be entered from eastward, northward of Sutton Island, by vessels of

the deepest draft. The approach from southward across Cranberry Island Bar has a depth of 14 feet (4.3 m.).

Deep-draft vessels can anchor midway between Greening Island and the southern shore, in 7 to 9 fathoms (12.8 to 16.5 m.). Smaller vessels can anchor farther in, the depths shoaling gradually to 12 feet (3.7 m.) 150 yards eastward of the islet which lies 400 yards from the head of the harbor. In the da

In the daytime, with clear weather, a pilot is not required to enter from eastward. Strangers coming from westward and crossing Bass Harbor and Cranberry Island Bars can take a pilot at Bass Harbor, if desired. Pilots for the waters eastward and westward can generally be found at South West Har:kor by making inquiries on shore. Anthracite coal, water, and ship *chandler's stores in limited quantities can be had alongside the Wharves: -: There is steamer communication with Bar Harbor and points westward along the coast to Rockland.

South West Harbor is the name of the village and resort on the north side of the harbor. The steamer landing on Clark Point is the principal wharf and has a depth of about 14 feet (4.3 m.).

Manset, on the south side of South West Harbor, has several fish cannery wharves, varying in depth from 8 to 15 feet (2.4 to 4.6 m.).

Greening Island, on the north side at the entrance of South West Harbor, is low and wooded, but has several houses visible. A large house at the eastern end is prominent. It has several float landings. Shoals border it on all sides.

The passage between Greening Island and the point westward has a least found depth of 15 feet (4.6 m.) and is extensively used. It is buoyed, and a ledge in the middle is marked by a light on a spindle. The best water from southward leads 100 to 150 yards westward of the red buoy at the south end, 100 yards eastward of the light, and eastward of the black buoy a little northward of the light.

Somes Sound (chart 306 or 307) is a narrow body of water, about 412 miles long and 14 to 34 mile wide, making into the south shore of Mount Desert Island. It lies between steep, rocky shores and has a narrow entrance with few dangers. With the aid of the chart good anchorage can be selected in the sound in 9 to 12 fathoms (16.5 to 21.9 m.), but it is out of the way and little used. Sailing vessels should enter under easy canvas on account of the heavy squalls of wind which occasionally strike down from the mountains. Greening Island lies in the middle of the approach, with a channel on either side of it.

Hall Quarry is an unused quarry and small settlement on the west side of Somes Sound 31/2 miles above the entrance.

Somes Harbor is a small cove at the head of Somes Sound. The entrance is narrow and marked by buoys.

Somesville (Mount Desert post office) is a village on Somes Harbor. The principal wharf has a depth of 8 feet (2.4 m.).

North East Harbor has its entrance northwestward of Bear Island. The head of the harbor is shoal, but there is anchorage 200 yards wide for very small vessels for a distance of 38 mile inside its entrance, favoring the western side, in 3 to 4 fathoms (5.5 to 7.3 m.). Vessels generally anchor just outside the entrance, between it and buoys Nos. 2 and 4, in 4 to 6 fathoms (7.3 to 11 m.). There are several large summer hotels on the shores of the harbor, and it is

an important yachting center. There are several landings for small craft. The harbor is little used except by yachts. The steamer landing for North East Harbor is 34 mile westward of the entrance and just westward of Gilpatrick Cove.

A rock, bare at low water, lies in the middle of the entrance to North East Harbor, and is marked by a buoy on either side. The best passage into North East Harbor lies westward of the rock.

Bear Island, on the eastern side of the entrance to North East Harbor, is high and marked on its western end by a lighthouse. The passage north of the island is blocked by reefs. There is a buoy depot of the Lighthouse Service on the northwest side of the island.

Sutton Island, about 1 mile long and wooded, lies in the middle of the passage between the south shore of Mount Desert Island and Cranberry Islands. Sutton, a post office and summer resort, is on its western part. There is a small wharf and several float landings. The channel north of Sutton Island has a depth of about 8 fathoms (14.6 m.) and is generally used—the ledges are marked by buoys. The channel south of it has a depth of about 17 feet (5.2 m.) and is contracted by rocks; the principal dangers are marked by buoys, and its navigation is not difficult in the daytime with the aid of the chart.

Bracy Cove, 5/8 mile eastward of Bear Island, is exposed to southeast winds, has a rocky and uneven bottom, and is unfit for anchorage.

Seal Harbor makes into the south shore of Mount Desert Island about 138 miles east of Bear Island; it is an anchorage for small vessels, but is exposed to southeasterly winds. There is a steamboat landing, depth îl feet (3.4 m.), and the village of Seal Harbor, a summer resort, on the eastern shore, and a coal wharf on the western side. A black buoy marks the end of the ledge which extends from the western shore Halfway across the entrance of the harbor. The anchorage is about 400 yards in diameter, in the middle of the cove, in 16 to 18 feet (4.9 to 5.5 m.); the head of the cove must be given a berth of over 300 yards. The approach is between Seal Harbor gas buoy on the east and Bowden Ledge buoy on the west. Seal Harbor has steamer service with Bar Harbor and Rockland.

East Bunker Ledge, 1 mile eastward of Sutton Island, is 1/4 mile long and has two sections bare at high water. There is a stone beacon near its southwestern end and a black buoy marking a 6-foot (1.8 m.) rock 200 yards northward of its northern end.

DIRECTIONS, SOUTH WEST HARBOR

The channel northward of Sutton Island is deep and well marked and has been examined by means of a wire drag; it is used by all vessels entering from northward and by most of those entering from eastward and southeastward. The channel southward of Sutton Island has unmarked rocks with a least found depth of 16 and 17 feet (4.9 and 5.2 m.). It has been examined by means of a wire drag. Its navigation is easy in the daytime with the aid of the chart. Vessels of 14 feet (4.3 m.) or less draft, approaching from southward or westward, usually enter through Western Way, but this passage is not recommended for strangers with a greater draft than 10 feet (3 m.),

From eastward, northward of Sutton Island.-Pass 200 yards southward of Seal Harbor gas buoy and steer 259o true (W. 5/8 N. mag.) for the southeast end of Greening Island, until midway between Bear Island and the western end of Sutton Island. Then steer 249o true (W. 14 S. mag.) and pass 100 to 200 yards southward of the red buoy lying nearly 200 yards southward of the southeast end of Greening Island. Then steer 269o true (WNW. 12 W. mag.) and select anchorage according to draft.

From westward through Western Way.-Crossing Bass Harbor Bar close to the fairway buoy lying about 350 yards southward of Bass Harbor Head Lighthouse, steer 89o true (ESE. 12 E. mag.) and pass about 100 yards southward of Long Ledge black bell buoy. Round the buoy at this distance and steer 25o true (NE. 18 N. mag.) for a little over 1 mile to the fairway buoy.

From the fairway buoy steer northeastward about 300 yards and pass between Cranberry Island Ledge red buoy and Flynn Ledge black buoy. From the latter buoy steer 356o true (N. by E. 14 E. mag.) for the fairway buoy at the northern end of Western Way. Then steer 323° true (N. by W.58 W. mag.) and follow the western shore at a distance of about 400 yards into South West Harbor.

Approaching southward of Long Island, pass about 1 mile southward and eastward of Long Island Head and steer 6° true (NNE. 14 E. mag.) for nearly 8 miles, passing 3/8 mile eastward of The Drums buoy, 14 mile westward of South Bunker Ledge spindle, and to the fairway buoy nearly 34 mile northward of the spindle. Then proceed as directed in the preceding paragraph.

ISLANDS OFF BLUE HILL BAY

(Chart 308.) Under this heading are described all of the islands southward of Bass Harbor Bar and Casco Passage from the Duck Islands westward to Swan Island.

This area includes numerous islands, generally wooded and having few prominent marks. The only ones having settlements are Swan Island, Long Island, and Great Gott Island. The area is very broken and rocky and has numerous bare and submerged ledges, many of them unmarked. The through route by way of Casco Passage and Bass Harbor Bar is used by many vessels, but the passages through the islands southward are seldom used except by local fishermen. With the exception of the broad channel leading between Black and Placentia Islands on the east and Long and Swan Islands on the west, which has been examined by means of a wire drag, the area has not been closely examined and strangers should use it with extreme caution and should avoid crossing broken areas.

Great Duck Island, the most southeasterly of the islands off Blue Hill Bay, is partly wooded and appears as two islands from eastward or westward. The lighthouse at the south end and the buildings around it are prominent.

Great Duck Island Lighthouse is a white cylindrical tower. The light is flashing red (flash 1 second, eclipse 9 seconds), 67 feet (20.4 m.) above the water, and visible 14 miles. The fog signal is an air diaphone sounding a 21/2-second blast every 20 seconds.

Little Duck Island, 34 mile north-northeastward of Duck Island, is partly wooded and has no distinguishing marks.
