BRITISH COLUMBIA.

Queen Charlotte Islands. — Skidegate Inlet. — Shoals in Approach and Entrance.—Track recommended.

1. Shoals :—
   (a.) Position.—At a distance of 5 miles, $32^{\circ}(N. 5^{\circ} E. mag.)$, from the northern extremity of Spit Point. Lat. $53^{\circ} 20'$ N., long. $131^{\circ} 44' 15''$ W. Depth.—2 fathoms. Remarks.—This shoal is about one mile in extent.
   (b.) Position.—At a distance of 4 miles, $58^{\circ}(N. 31^{\circ} E. mag.)$, from the northern extreme of Spit Point. Lat. $53^{\circ} 17' 50''$ N., long. $31^{\circ} 43' 15''$ W. Depth.—2 fathoms. Remarks.—This shoal is almost joined to the main spit.
   (c.) Position.—Spit Point bar. Depth.—The depth on this bar, which extends nearly 10 miles, north-westward, from Spit Point, is generally less than is now shown on the charts, and the channel southward of Bar Rocks has silted up to a depth of only 12 ft. Remarks.—The leading-lines for the channels southward and northward of Bar Rocks have been erased from Chart No. 48.
   (d.) Position. — Abreast of Lawn Point. Depth. — The channel between Lawn Point and the northern end of the bank extending from Bar Rocks has silted up to form a bar with a depth of only 5 fathoms.
   (e.) Position.—Off edge of shore bank, south-eastward of Dead Tree point, at a distance of $2 \frac{3}{4}$ miles, $226^{\circ}(S. 19^{\circ} W. mag.)$, from the western Bar Rock. Lat. $53^{\circ} 20' 40''$ N., long. $131^{\circ} 54' 20''$ W. Depth.—$1 \frac{1}{2}$ fathoms.
   (f.) Position.—In entrance to Village Bay, at a distance of 4 cables, $13^{\circ}(N. 14^{\circ}W. mag.)$, from the north-western extreme of Bare Islet. Lat. $53^{\circ} 16'$ N., long. $131^{\circ} 58'$ W. Depth.—$2 \frac{1}{2}$ fathoms.
   Remarks.—The astronomical positions given above are those on Chart No. 1923a.

2. Track recommended :—
   Details.—When approaching Skidegate Inlet from the eastward, the white patch boulder near Lawn Point should be brought to bear $252^{\circ}(S. 45^{\circ}W. mag.)$. When the light-and-bell buoy bears $196^{\circ}(S. 11^{\circ}E. mag.)$, course should be altered to leave it close to on the port hand, when a course $180^{\circ}$ ($S. 27^{\circ}E. mag.$) will lead in the deepest water to the black can buoy south-eastward of Dead Tree Point. After leaving this buoy close to on the port hand, the west side of Leading Island should be brought open of the east side of Bare Islet bearing about $209^{\circ}(S. 2^{\circ}W. mag.)$, which will lead up until abreast of Image Point.
   Variation.—$27^{\circ}E$.

Burrard Inlet.—Vancouver Harbour.—Light-and-bell Buoy established.
