island and_ rather farther off Half Moon. island. The land bordering the northeastern corner of Georgian bay is very low : with no prominent. natural marks that can be picked up from a distance, and as the shoals extend about 5 miles out great vigilance will 'be necessary to pick up the buoy. The entrance buoy is moored well clear of all shoa!s and may be ap- proached with safety from all direc- tions between west and south-south- east. The best time to make the land is after ten o'clock in the forenoon, when the sun lights up the shore and the white beacons. In thick weather or at night, when approaching the shore, get the lead going in good time and on no account shoal to less than 10 fathoms until some known mark appears. After passing entrance gas buoy No. 2, keep Dead island beacons in line bearing N. 58 deg. E. trie (NE. by E. % E. mag.) for 2.6 miles, passing on the port hand black spar buoy No. 3, distant 400 ft., and black spar buoy No. 5, distant 850 ft., and on the starboard hand red spar buoy No. 4, distant 1,600 ift., off Francis Smith shoal, and red spar buoy No. 6, dis- tant 3UC ft, 'When the distance has been run red gas buoy No. 8 will be found close under the starboard bow and the helm must be immediately ported to swing closely round the buoy and bring the Keefer beacons in one, bear- ime S, 87 deg.

While on the Keefer range black spar buoys No. 9, distant 750 ft., No. 11, distant 180 ft., and No. 13, distant 210 t, wil be passed on 'the port hand, and red spar buoys No. 10, dis- tant sO0 ft. and No, 12, distant 225 ft., on the starboard hand.

No. 20 distant 75 ft., and red spar buoy No. 22, distant 500 ft. Upon this Wedge island range, be- tween red gas buoy No. 20 and black spar buoy No. '21, the channel will be found very narrow, and great care THE Marine REVIEW must be taken to tbe exactly on the range when passing the gas buoy and a little southeastward .of it when passing buoy No. 21 to avoid the middle ground, which is covered with 12 ft. of water and trends parallel to the range for 200 pards.. After passing red spar buoy No. 22 a vessel may port her helm slightly, heading N. 6/7 deg. E. true (ENE. 54 E.

E.. true (ESE. 34 & Bly mag.). . Keep this on for 3% mile to the wharf. Great care must be exercised on this range because it is astern, the beacons are rather close together, and the channel is very narrow. The black buoys passed on_ this ange on the port: hand are, No. 23, off Wedge island reef, distant 100 ft., No. 27, distant 100 ft., and No. 20, the same distance; on the starboard hand are red gas buoy No. 24, distant 100 it., red gas buoy No, 26, distant 50 it., and red spar buoy No. 30, distant 200 ao At the wharf ample water will be found, but the channel is so narrow that local knowledge is desirable for turning about the outer end. The water along the northern side of the wharf is good for a length of 150 ft. and a width of 125 ft. Along the southern side 27 ft. may be found for a distance of 500 ft. from the outer end, but this lane of water is only 200 ft. wide, the southern limit being marked by red spar buoy No. 32. Leaving the harbor--When fast to the southern side of the wharf heading out, Dokis beacons will be seen in one bearing N. 84 deg. 45 min. W. true (WNW. Cast off and keep them exactly on for 1,400 yards or until red gas buoy No. 24, off Mann island reef, is reached. Starboard slowly, to 'bring red gas buoy No. 20 ahead and the rear Wedge beacon slightly open south- eastward of the front one, so as not to get too close to the middle ground, marked at its southwestern end by black spar buoy No. 21. When red gas buoy No. 20 is reached, bring Wedge island beacons in one astern, heading S. 58 deg. 15 min.

The annual report of this company just issued says: During the past year the works have been principally employed in the completion of the turbine engines for H. M. battleship St. Vincent. The directors are pleased to report that the application of turbine machinery of Parsons' type in war vessels and in vessels of the mercantile marine continues to extend. The total horse- power of turbine engines delivered and under construction by the company and licensees, including the ental sub-companies and licensees of Parsons Pocergn. Patents. Co.,". Ltd, amounts to over 3,000,000 H. P. since the commencement. Since last report the United States 'Navy have entered into arrangements to' manufacture turbine engines for the battleship Florida in their navy yard at Brooklyn, and have also adopt- ed turbines of Parsons' type for the greater part of their new construc- tion. A combination of low-pressure turbines and _ reciprocating engines, fitted in the yacht Emerald, owned by Sir Christopher Furness, the Otaki, built by W. Denny & Brothers for the New Zealand Shipping Co., Ltd., and the Laurentic, built by Harland & Wolff, Ltd. for the White Star Line, have proved eminently satisfac- tory. The results obtained with 'the Otaki have led to the New Zealand Shipping Company placing an order with W. Denny & Brothers for a second vessel to be fitted with the combination system. In view of the very large field open in tramp steamers, which at present is untouched by the turbine, the direc- tors have instituted ascertain the most suitable arrange- ments for such vessels. They hope these may lead to a successful so!u- tion of the question. The steamer Vespasian has ibeen purchased and particulars' of steam and coal con- sumption under loaded conditions with the triple-expansion reciprocating en- gines of this vessel having been ob- tained, these engines are being taken out, and preparations made for in- stalling turbine machinery as soon as it is completed.
