SUBMARINE LAMPS AS PILOTS: HARBOUR CHANNELS OUTLINED IN UNDER-WATER LIGHTS.
We illustrate here a system of submerged lamps for guiding vessels into port, invented by M. Léon Dion. It consists of a chain of electric lamps laid under water to mark the navigable channel, connected by an electric cable controlled from the shore. In time of war, of course, the light would be switched on only when a friendly vessel was signalled.—[By Courtesy of the "Scientific American."]
COMPRESSED AIR FOR "PLUGGING" HOLED SHIPS: AN INTERESTING NAVAL EXPERIMENT.
This method of stopping the inrush of water was tested on the U.S. battle-ship "North Carolina." An American naval officer wrote: "Its use will permit us to repair from inside all holes made beneath the water-line. Strong pressure is exerted in the holed compartment; slighter pressure, graduated, in those adjacent (shaded darker)."—[By Courtesy of "Popular Mechanics" Magazine, Chicago.]

CHRISTMAS DAY ON BOARD SHIP IN THE NORTH SEA: THE CAPTAIN GOING ROUND THE MESSES "TASTING THE MEN'S DINNER."
By time-honoured naval usage, on Christmas Day, after Divine Service, on board every ship, the officers, headed by the Captain, visit the men at dinner in their messes, which are always gay with seasonable decorations. At the end of each table stands the cook of the mess, to offer the Captain samples of the dinner he has prepared. These are tasted by the officers, and, with a hearty exchange of good wishes, the procession passes from table to table. It is stated that the officers of the Grand Fleet collectively subscribed to provide Christmas dinners at home for the children of their men. It is certain that friends at home provided Christmas fare for the crews in the North Sea. Never was there a year when seasonable goodwill and seasonable good cheer were more desirable.—[From a Drawing by S. Begg.]
