Lights and Buoys.-In view of the difficulties attending navigation in the Gulf, and the impossibility of arranging with the Governments of the littoral for the provision of lights and buoys except on terms which would have greatly hampered shipping, the British Government, in view of the great preponderance of British shipping in the Gulf, has established since 1912 a very complete system of lights and buoys, the cost of which is shared in equal moieties by the Government of India and H.M.
The east breakwater scheme, which would have covered the Platter's rocks - still very troublesome - and the Skinner's, was abandoned for buoys which mark the spots.
This and other points on the route were marked by buoys laid after careful triangulation by Capt.
In the Shore Whaling, on soundings, among the Bays of New Zealand, when a Right Whale gives token of sinking, they fasten buoys to him, with plenty of rope; so that when the body has gone down, they know where to look for it when it shall have ascended again.
To oversee all the details yourself in person; to be at once pilot and captain, and owner and underwriter; to buy and sell and keep the accounts; to read every letter received, and write or read every letter sent; to superintend the discharge of imports night and day; to be upon many parts of the coast almost at the same time--often the richest freight will be discharged upon a Jersey shore;--to be your own telegraph, unweariedly sweeping the horizon, speaking all passing vessels bound coastwise; to keep up a steady despatch of commodities, for the supply of such a distant and exorbitant market; to keep yourself informed of the state of the markets, prospects of war and peace everywhere, and anticipate the tendencies of trade and civilization--taking advantage of the results of all exploring expeditions, using new passages and all improvements in navigation;--charts to be studied, the position of reefs and new lights and buoys to be ascertained, and ever, and ever, the logarithmic tables to be corrected, for by the error of some calculator the vessel often splits upon a rock that should have reached a friendly pier--there is the untold fate of La Prouse;--universal science to be kept pace with, studying the lives of all great discoverers and navigators, great adventurers and merchants, from Hanno and the Phoenicians down to our day; in fine, account of stock to be taken from time to time, to know how you stand.
Using these buoys to guide the direction of tow, a grapnel, a species of fivepronged anchor, attached to a strong compound rope formed of strands of steel and manila, is lowered to the bottom and dragged at a slow speed, as it were ploughing a furrow in the sea bottom, in a line at right angles to the cable route, until the behaviour of the dynamometer shows that the cable is hooked.
The harbour of Port Blair is well supplied with buoys and harbour lights, and is crossed by ferries at fixed intervals, while there are several launches for hauling local traffic. On Ross Island there is a lighthouse visible for 19 m.
The Venetians had taken up the buoys which marked the fairway, and had placed a light squadron on the lagoon.
The ocean of water buoys or floats the ship, and the ocean of air, or part of it in motion, swells the sails which propel the ship. The moving air, which strikes the sails directly, strikes.
Shore lights and unlighted buoys have also been provided where necessary.
