PROPOSED PNEUMATIC BALANCE LOCK FOR THE NEW NIAGARA OR WELLAND CANAL. CONTINUED FROM PAGE 6. from one chamber to the other, and the whole moves as swiftly as is consistent with safety. The whole principle is exactly the same as that of the balance scale, the motion being due to a small difference in the total weights of the water in the two locks. The latter, of course, move up and down, oppositely and synchronously. In place, therefore, of the slow, clumsy, and enormously costly lock system now in use, whereby a vessel is let into the empty lock, the gates closed, and the vessel raised by slowly fill- ing the well, or vice versa, lowering by emptying the well, the new proceeding will be this: A vessel will be let into both the raised and depressed locks, or, in the absence of two vessels, enough water let into the empty tank of the empty lock to about equalize the weight of the other; then enough water let into the upper lock to displace the balance; the compressed-air conduit is opened, the brakes set free, the upper lock sinks, the lower rises, the position of the two is reversed, the gates are opened, the vessel cleared, all in a few minutes.” It requires a more vivid imagination than most people possess to believe that this scheme is mechanically prac- ticable, or that if practicable the millions that it would cost can be provided, or that if built it would ever earn a fraction of the operating expenses. —_—— ee SO NOTICE TO MARINERS.

Notice is hereby given that, on the opening of naviga tion, 1897, a gas buoy, painted red showing a fixed white light, will be moored in the position heretofore ocecupie? ‘by inner end of straight Cut Lighted Buoy, No. 30, on the northwesterly side of the extreme inner end of the Straight Channel, Maumee Bay. Manhattan Range (front) Light, SW. 7-8 W., about 2,500 feet. All mariners, and especially those having vessels or rafts in tow, are cautioned to avoid fouling this buoy. FORTY-MILE POINT LIGHT STATION. Notice is herby given that, on or about April 30, 1807, a light of the fourth order, showing a white flash every 10 seconds, will be established in the structure recently erected on Forty-Mile Point, northwesterly part of Lake Huron. The light will illuminate 315 degrees of the horizon, ard will be visible from all points of approach from the lake. The focal plane of the light will be 66 feet above the mean lake level, and the light may be seen 15 3-4 miles in clear weather, the observer’s eye 15 feet above the lake. The light will be shown from a black lantern surmount- ing a square, red, brick tower, rising in the center of the front of a double, red, brick dwelling, with red roof. The approximate geographical position of the light, as taken from Chart No. 22 (Lake Huron) of the United States Survey of the northern and northwestern lakes, will be: Latitude, north, 45 degrees, 29 minutes, (04 seconds); longitude, west, 83 degrees, 53 minutes, (55 seconds). Bearings of prominent objects from the station are: Presque Isle Lighthouse, S. 66 degrees E. (SE. by E. 7-8 E.), 22 1-6 miles; Spectacle Reef Lighthouse, N. 29 degrees W. (NNW. 5-8 W.), 22 3-8 miles. During thick or foggy weather a 10-inch steam whistle will sound blasts of 3 seconds’ duration separated by si- lent intervals of 17 seconds, thus: Silent _ Silent Blast interval Blast interval emus — mason! a 3 sec. 17 sec, 3 sec. 17 sec.

PLUM ISLAND RANGE LIGHT STATION. Front Light.—Notice is hereby given that, on or about May 1, 1897, a fixed red light of the sixth order will be established in the structure recently erected on the south- erly side of Plum Island, Porte des Morts Passage from Lake Michigan into Green Bay. The light will be shown from a single window in the front of a small, white, two- story tower, square at the base and octagonal at the top, clap-boarded and shingled, and having a black roof. The focal plane of the light will be 32 feet above mean lake level; the light will be visible about 8 1-2 miles in clear weather, and through a small are on either side of the range line. Bearings and distances of prominent objects from the . tower are: Portes des Morts (Pilot Island) Lighthouse, S. 51 degrees E. (SE. 9-16 E.), 2 1-16 miles; tangent to Table Bluff, S. 84 degrees, 30 minutes W. (W. 1-2 S.), 3 1-16 miles; tangent to Death Door Bluff, S. 86 degrees, 30 minutes W.-(W. 5-16 S.), 5. 3-16. miles. Rear Light.—On the same date a fixed red light of the - fourth order will be established in the structure recently erected on the westerly side of Plum Island, 1,650 feet (5-16 mile) N. 29 degrees, 30 minutes W. (NNW. 5-8 W.) in rear of the front light. Be tevt The focal plane of the light will be 68 2-3 feet above mean lake level, and the light should be seen about 13 miles in clear weather. The light will illuminate about 231 degrees of the horizon lying to the westward of N. 31 degrees, 30 minutes W. (NNW. 13-16 W.) and S. 19 degrees 30 minutes W. (S. by W. 3-4 W.) (bearing from a vessel). The structure consists of white, square, pyramidal, iron, skeleton tower surmounted by a cylindrical watch room anda black octagonal lantern. A two-story, buff, brick, double dwelling, with red roof, stands about 100 feet SSE. from the tower. The approximate geographical position of the tower, as taken from Chart No. 35 (South end of Green Bay) of the United States Survey of the Northern and Northwestern lakes, is: Latitude, N. 45 degrees, 18 minutes (29 seconds); longi- tude, W. 86 degrees, 57 minutes (15 seconds).
