The generally used inside route, used by most vessels of 12 feet (3.7 m.) or less draft, across Bass Harbor Bar and through Casco Passage, leads across the south end of Blue Hill Bay. Directions for it are given on page 42.

The vessels bound to points in Blue Hill Bay do not often exceed 12 feet (3.7 m.) draft, and these vessels usually follow the inside passage, generally entering from eastward across Bass Harbor Bar and from westward by the passage between Pond Island and Blue Hill Bay Lighthouse. Vessels of too deep draft, or when there is too much easterly or southeasterly swell on Bass Harbor Bar, can enter the bay southward of Little Gott and Placentia Islands and northward of Black Island, but this passage has not been closely examined and is not recommended for a greater draft than 15 feet (4.6 m.). Vessels of the deepest draft can enter by the main channel between Black and Placentia Islands on the east and Long and Swan Islands on the west. This passage has been covered sufficiently by means of a wire drag to insure a clear channel as indicated on the chart.

Above the entrance, Blue Hill Bay is deep and generally free from dangers, and several channels are available.

From Bass Harbor Bar.-Directions to Bass Harbor Bar from eastward and from Bass Harbor Bar westward through Casco Passage are given on page 41. Vessels bound from Bass Harbor Bar to Union River usually use the channel between Tinker and Hardwood Islands, and between Long and Bartlett Islands. This channel is deep and unobstructed and the chart and buoys are the guides. Small craft sometimes use the more protected passage between Moose and Hardwood Islands and through Bartlett Narrows (described on p. 109). Bound to Blue Hill Bay from Bass Harbor Bar, the most direct route leads eastward of the chain of islands and reefs extending from Ship and Barges Ledge to Tinker Island, and southward and westward of Long Island. It is deep and clear and the chart is the guide.

Entering between Black and Placentia Islands. This passage has a rock with a least found depth of 18 feet (5.5 m.), not closely examined, 250 yards off the southwest end of Little Gott Island. Vessels of 15 feet (4.6 m.) or less draft may use it by favoring the north shore of Black Island, 250 yards off, after passing Inner Dawes Ledge (a rock islet), and round the north end of Black Island at a distance of 200 yards. Then steer west-southwestward and round the southwestern end of Placentia Island at a distance of 400 to 500 yards. The course can then be shaped northward into Blue Hill Bay, or if bound to Casco Passage, northeastward to pass northeastward of Staple Ledge buoy and North Point of Swan Island. Directions through Casco Passage are given on page 42.

Entering from southward.-Pass 34 mile eastward of Long Island Head, and steer 334° true (N. 34 W. mag.) for the western end of Green Islands. Or, passing 3% mile or more southward of Great Duck Island Lighthouse, bring it astern on a 282° true (NW. by W. % W. mag.) course, heading for the western end of Green Islands, and pass about 3 mile northeastward of The Drums buoy. Pass 400 to 500 yards westward of Green Islands and steer 315° true

(NNW. % W. mag.) for 24 miles to a position 1/4 mile westward of Placentia Island. The course can then be shaped as desired.

Entering from westward.-Vessels entering Blue Hill Bay from westward generally come through Eggemoggin Reach or Deer Island Thorofare, and enter Blue Hill Bay by the passage between Pond Island and Blue Hill Bay Lighthouse. The regular steamer, drawing about 10 feet (3 m.) and entering from Eggemoggin Reach, passes between Hay Island Ledge horizontally striped buoy and the red buoy northward, then between Smuttynose and Mahoney Islands, then close eastward of the black buoy 3% mile southward of Blue Hill Bay Lighthouse, and then between Blue Hill Bay Lighthouse and Sand Islet. This route should not be used by strangers except in small craft. The deeper channel (about 19 feet (5.8 m.)) leads through the buoyed channel 1/2 mile northward of Pond Island. Vessels entering Blue Hill Bay from Eggemoggin Reach can use the directions on page 51. Entering from Deer Island Thorofare, they can use the directions on page 50 to Egg Rock beacon in Jericho Bay. From a position 1/4 mile west of Egg Rock beacon steer 19° true (NE. 34 N. mag.) for 34 miles, passing 3% mile east-southeastward of Mahoney Island, to a position 50 yards westward of buoy No. 3, and then 69° true (E. 14 N. mag.) passing 50 yards southward of a red buoy and 100 yards northward of a black buoy, into Blue Hill Bay. The course can then be shaped as desired.

JERICHO BAY

(Chart 308) is the body of water between Swan and Marshall Islands on the east and Isle au Haut and Deer Isle and adjoining islands on the west. The inside routes leading from Casco Passage and York Narrows to Deer Island Thorofare and Merchant Row and from the passage north of Pond Island to Eggemoggin Reach lead across its head, and this section is used by many vessels. The part of the bay southward of these thorofares has deep water but there are many ledges, rocks, and small islands, and this part is little used except by local fishermen.

The islands on the eastern side are described under "Islands off Blue Hill Bay" on page 104. Casco Passage and York Narrows, the passage north of Pond Island, and Herrick Bay are described under "Blue Hill Bay." Some of the dangers on the western side are described with Merchant Row and Deer Island Thorofare following.

Spirit Ledge, 34 to 14 miles southwestward of Marshall Island, is in two sections; the northeastern is bare at high water and the southwestern is bare at about half tide.

Boxam Ledge, off the southwest side of Marshall Island, is bare at low water.

Drunkard Ledge, 2 miles southwestward of Marshall Island, is bare at low water.

Marshall Ledge, off the west side of Marshall Island, is bare at low water.

Directions, Jericho Bay, from southward.-The channel leading into Jericho Bay between Spirit Ledge and Three Bush Island on the east, and Drunkard Ledge, Blue Hill Rock, and North Popplestone Ledge on the west, the main part of the bay northward, and

also the channel leading into the bay between Marshall and Swan Islands, have been partially examined by means of a wire drag. Approaching from southward, it is advisable to pass between Marshall and Swan Islands, where the dangers are well marked. The entrance between Marshall Island and Isle au Haut is obstructed by a number of unmarked submerged ledges, and is little used.

Vessels may pass 1/4 mile southward of Southwest Point of Long Island, steer 267° true (WNW. 5% W. mag.) for 134 miles to a position 1/4 mile south-southwestward of a red buoy, then steer 301° true (NW. 3% N. mag.) for 53% miles, passing midway between Green and Brimstone Islands, 350 yards northeastward of Ringtown Island, 200 yards northeastward of the black buoy northward of Marshall Island, and to a position 200 yards southwestward of the red buoy westward of Hat Island; or from the whistling buoy 134 miles southeastward of Heron Island, a 337° true (N. 12 W. mag.) course for 2 miles will lead to a position midway between Green and Brimstone Islands, and the 301° true (NW. 3 N. mag.) course can then be followed to a position 200 yards southwestward of the red buoy westward of Hat Island.

Bound to Merchant Row.-From this position, vessels steer 261° true (W. % N. mag.) passing northward of a black bell buoy and 14 mile northward of West Halibut Rock horizontally striped buoy, to a position 1/2 mile westward of West Halibut Rock, then follow directions on page 43.

Bound to Deer Island Thorofare.-From a position 200 yards southwestward of the red buoy westward of Hat Island, vessels can steer 310° true (NNW. % W. mag.) for 21⁄2 miles, passing 1/4 mile northeastward of Whaleback Ledge red buoy, and to a position 200 yards southwestward of Shabby Island (marked by a few trees). Then bring Shabby Island astern on a 293° true (NW. % W. mag.) course, with Sheep Island a little on the port bow, and pass 250 yards northeastward of black buoy No. 1 and 100 yards northeastward of black buoy No. 3; then haul westward and follow the directions for Deer Island Thorofare on page 42.

Bound to Eggemoggin Reach.-Pass 200 yards westward of the red buoy westward of Hat Island and steer 0° true (N. by E. 5% E. mag.) for 25% miles to 3% mile west of Egg Rock beacon. Then steer 330 true (N. by W. mag.), heading for Devils Head, until midway between Hay Island Ledge buoy and Channel Rock buoy, and then haul northwestward and follow the directions given on page 43.

EGGEMOGGIN REACH

(Chart 309) lies between the Deer Isles and the mainland and connects Blue Hill Bay and the head of Jericho Bay with Penobscot Bay near its head. It is 11 miles long and has a least width of 3⁄4 mile at Byard Point. The reach has several villages along its shores. Regular steamers between Rockland and Blue Hill make landings at all of the villages. The eastern entrance is well marked by Devils Head, a prominent, high rocky bluff on the south end of Hog Island, and the western entrance by Pumpkin Island Lighthouse (white tower connected with dwelling) and Cape Rosier (high and thickly wooded), The main channel through Eggemoggin Reach has been examined by means of a wire drag. The depth is sufficient for deep-draft ves

sels, but the channel is narrow and the bottom irregular in places and the passage is not recommended for a greater draft than 18 feet (5.5 m.) except with local knowledge. The principal dangers for this draft are buoyed, and can be easily avoided in the day time and clear weather.

Mahoney Island, just eastward of the entrance to Eggemoggin Reach, has scattered trees. Smuttynose Island, 1/2 mile northwestward of Mahoney Island, is grass covered. Mahoney Ledge, westward of Mahoney Island, is partly bare at low water.

Greenlaw Cove, on the southwest side of the eastern entrance to Eggemoggin Reach, has a narrow unmarked channel with shoals on both sides, and is suitable only for small craft with local knowledge. Mountainville is a post village near the head. The landing is said to be nearly bare at low water. There is little business by water.

Devil Head Ledge, extending 1/4 mile southeastward from Devils Head, is partly bare at high water and marked off its end by a red buoy. Channel Rock is bare at extreme low water and marked by a black buoy. The Bowlders, 400 yards northwestward of Channel Rock, are bare at low water.

Naskeag Harbor, north of Harbor and Hog Islands, has a fish cannery and the post village of Naskeag on the north side. The harbor can be entered from eastward or westward, but there are many unmarked dangers and strangers should not attempt to enter except in small craft.

Centre Harbor, a small cove on the eastern side of the Reach northeastward of Torry Islands, is an anchorage for small craft only. The town of Brooklin is at the head of the harbor. A rock marked by a black spindle with cage lies in the middle of the entrance northward of Chatto Island; the channel is close southward of the rock. Between the spindle and the fish factory on the north side the cove has depths of 8 to 10 feet (2.4 to 3 m.), and above this is mostly dry at low water. The steamer landing is on the north side at the entrance and has a depth of about 14 feet (4.3 m.). There is good anchorage off the entrance in 4 fathoms (7.3 m.) bottom soft in places. The main approach to Centre Harbor is from westward, but local vessels enter by the channel eastward of Torry Islands, passing in mid-channel on either side of the bare rock 350 yards eastward of the easterly Torry Island. This passage should be used by strangers only in small craft.

Benjamin River, the approach to the town of Sedgwick, makes into the eastern shore 2 miles northward of Center Harbor. The channel at the entrance, northward of Cape Carter, has a least depth of 19 feet (5.8 m.), but is much obstructed by ledges on both sides, leaving a passage only 100 yards wide at its narrowest part. The town of Sedgwick can only be reached at high water, as the river runs dry some distance below.

North Deer Isle is a post village at the north end of Deer Isle. The steamer wharf, known as Scotts Landing, % mile westward of Tinker Ledges, has a depth of about 14 feet (4.3 m.). Gasoline and some supplies are available.

Billings Cove, on the northern shore of the Reach, lies east of Byard Point, marked by a large white house on the summit. It affords anchorage in the middle just inside the entrance in about 5

fathoms (9.1 m.). Sargentville, a post village on the eastern shore of the cove, is one of the landings for steamers passing through the Reach in summer. There is an automobile ferry between Sargentville and Scotts Landing.

Eggemoggin is a summer resort at the north end of Little Deer Isle southeastward of Pumpkin Island Lighthouse. The steamer wharf has a depth of about 12 feet (3.7 m.).

Buck Harbor is on the north side of the Reach, north-northeastward of Pumpkin Island Lighthouse; it affords excellent anchorage, and is often used by small vessels. Harbor Island, in the middle of the harbor, has a good channel around it, which forms the anchorage. Shoals extend 250 yards off the northeast side of Harbor Island, and the channel is narrow between them and the shore northeastward. Harbor Ledge, at the north end of the shoals, is marked by a black buoy. The channel between the rock and the north end of Harbor Island has a depth of 12 feet (3.7 m.). Small craft can anchor in the bight on the northeast side of Harbor Island. The best anchorage for vessels is westward and northwestward of Harbor Island, in 5 to 6 fathoms (9.1 to 11 m.). The post village and landing of South Brooksville is at the head of the harbor. The steamer wharf has a depth of 12 feet (3.7 m.). There are several hotels with float landings.

Orcutt Harbor lies just westward of Buck Harbor and northward of Pumpkin Island Lighthouse. It is about 114 miles long and 14 mile wide. It has good anchorage in 312 to 81/2 fathoms (6.4 to 15.5 m.) in the middle of the harbor just above a small wooded islet. A reef, bare at low water, extends 300 yards southward from Condon Point, on the east side at the entrance. When inside this reef, favor, if anything, the eastern side of the entrance to avoid a sunken rock lying nearly 200 yards from the western shore and the same distance southward of the wooded islet. In the slight expansion 1⁄2 mile above the islet care must be taken to avoid two sunken rocks, one lying 200 yards from the western shore and the other 150 yards from the southeast side of the expansion.

Horseshoe Cove is a long, narrow cove, the entrance to which lies northwestward of Pumpkin Island Lighthouse; it is navigable only for small craft with local knowledge. There are no wharves.

Thrumcap Island, 1 mile northward of Pumpkin Island Lighthouse, is low and grassy. Thrumcap Ledge, southwestward of Thrumcap Island, is partly bare at high water. Merriman Ledge is bare at low water only and marked by a black buoy on its north side.

Of the islands near the western entrance to Eggemoggin Reach, Spectacle Islands are grassy, Twobush Islet is bare, Hog Island has scattered trees and a house and barn in the center, and Pond Island is grassy, with a small clump of trees on the northeast side and a shanty at the south end. Western Island is grassy on its . eastern end and has a thick clump of trees on its western end." Green Ledge is grassy.

Anchorage.-Vessels can anchor anywhere in the Reach where the depth is suitable and the bottom soft, making a lee of either shore, according to the wind. Small craft anchor in the coves.

Tides.—The mean rise and fall of tides is about 10 feet (3 m.).
