The captain, from the bridge, lifts a small white flag as a signal to the wing-commander that all is ready. The latter nods to the pilot, who starts his engine at full speed, while two mechanicians, braced against cleats on the deck, hold back the tugging seaplane. If the "tone" of the engine is right, the wing-commander (standing in front of the plane, and a little to one side) brings down his red-and-yellow flag, with a sharp jerk, falls on his face to avoid a collision, and the machine, freed from the grip of the men holding it, jumps away. The next two seconds tell the tale, for if a seaplane "gets off the deck" properly, the rest of its flight is not likely to be "eventful."

At practice, a seaplane sails over and drops its detachable wheels near a waiting drifter, which picks them up and returns them to the ship. The machine swoops low, and "kicks" loose the "spares" at a hundred feet or less above the surface of the water, and a pilot who let his wheels go from a considerably greater altitude drew a growl from the bridge, as a long fall is likely to injure them. Its flight over, a seaplane returns to the ship by alighting on the water several hundred yards astern, and floundering up alongside as best it can. With a high wind and a choppy sea, it is rough work. The machine is so "balanced" that its tractor propeller should revolve in the air and clear the water by several inches, even in a rough sea. It will occasionally strike into "green water," however, which is always likely to shatter the ends of the blades, if nothing else. The sheathing of the blades with metal affords considerable protection, though a certain risk is always present. The operation of picking a seaplane up and hoisting it inboard is a nice piece of seamanship at best, but in bad weather is a practicable impossibility. With a wind much above thirty miles an hour, indeed, only a very real need is likely to induce a "mother ship" to loose her birds from the home nest. With a sea too rough to make it possible for a seaplane to live in it, it is sometimes possible to carry on imperative reconnaisance by sending up an ordinary aeroplane (some of which are always carried); though the latter must, of course, make its landing on terra firma when its work is over.

The wind had been freshening considerably all afternoon, but with no more than thirty miles an hour showing on the indicator, there was no reason for not letting me have my "balloon ride."

As the time approached for its ascent, the balloon was allowed to rise far enough from the deck to permit its car to be pushed underneath the centre of it, in order that the latter might not be dragged in the "getaway." I could now see that the monster had rather the form of the "bag" of an airship than the "silkworm-with-stomach-cramps" shape of the regulation modern observation balloon. Its nose was less blunt than that of the "sausage," and the ropes were attached so that it would be pulled with that nose boring straight into the wind, instead of tilted upwards like that of its army prototype. The three "stabilisers" at its stern were located, and appeared to function, similarly with those of the "sausage."

The basket was mid-waist deep, and just big enough to hold comfortably two men sitting on the strips of canvas which served as seats. Supplementing our jackets, two small life-preservers of the ordinary type were lashed to the inside of the basket. When I asked about parachutes, I was told that, while it was customary to carry them, on this occasion—as they were worse than useless to a man who had not practised with them—it was best not to bother myself with one. "Stick to the basket if anything happens," some one said; "it will float for a month, even if full of water." Some one else admonished not to blow up my jacket until we had stopped rising, lest it (from the expanding air, I suppose) should in turn blow me up. Then we were off. The last thing I noticed on the deck was the ship's cat, which I had observed a few moments previously rubbing his arched back ecstatically against a sagging "stabiliser," making a wild leap to catch one of the trailing guide-ropes.

"He always does that," I heard my companion saying behind me. "Some day perhaps he will catch it, and then—if it happens at a time when there isn't an opportunity to wind in and let him down easy—I'm afraid there won't be a one of his nine lives left in the little furry pancake it will make of him when he hits the water. It's surprising how the water will flatten out a—anything striking it at the end of a thousand feet fall. Only the week before last——"

To deflect the conversation to more cheering channels, I began to exclaim about the view. And what a view it was! The old Xerxes was lying well down towards one end of the mighty bay, so that without turning the head one could sweep the eyes over the single greatest unit of far-reaching might in the whole world war, the Grand Fleet of the British Navy. And in no other way than in ascending in a balloon or a flying machine could one attain a vantage from which the whole of the fleet could be seen. Looking from the loftiest fore-top, from the highest hill of the islands, there was always a point in the distance beyond which there was simply an amorphous slaty blur of ships melting into the loom of the encircling land. But now those mysterious blurs were crystallising into definite lines of cleavage, and soon—save where some especially fantastic trick of camouflage made one ship look like two in collision, or played some other equally scurvy trick on the vision—I could pick out not only battleships, but cruisers, destroyers, submarines, ranged class by class and row on row. Even the method in the apparent madness with which the swarms of supply ships, colliers, oilers, trawlers, and drifters were scattered about was discernible.

Save for the visibility, which was diamond-clear in the slanting light of the low-hanging winter sun, it was just an ordinary, average Grand Fleet day. A squadron of battleships was at target practice, and—even better than their own gunnery officers—we could tally the foam-jets of the "wides" and "shorts" and the narrowing "straddles." A squadron of visiting battle-cruisers had just come to anchor and were swinging lazily round to the tide. Two of them bore names which had echoed to the ends of the world; the names of two of the others—from their distinctive lines and great size, I recognised them as twin giants I had seen still in the slips on the Clyde scarcely a year previously—the world has never heard. A lean, swift scout-cruiser, with an absence of effort almost uncanny, was cleaving its way out toward the entrance just as a line of destroyers came scurrying in after the rolling smoke-pall the following wind was driving on ahead of them. Out over the open seas to the east, across the hill-tops of the islands, dim bituminous dabs on the horizon heralded the return of a battleship squadron, the unceremonious departure of which two days previously had deprived me of the last two courses of my luncheon. In the air was another "kite"—floating indolently above a battleship at anchor—and a half-dozen circling aeroplanes and seaplanes. Countless drifters and launches shuttled in and out through the evenly lined warships.

We were now towing with the cable forming an angle of about sixty degrees with the surface of the water, and running up to us straight over the port quarter. The ship had thinned down to an astonishingly slender sliver, not unsuggestive of a speeding arrow whose feathered shaft was represented by the foaming wake.

"She's three or four points off the wind," commented my companion, "and yet—once we've steadied down—you see it doesn't make much difference in the weather we make of it. A head wind is desirable in getting up to keep from fouling the upper works amidships, but we hardly need to figure it down to the last degree as in launching a seaplane. When we're really trying to find something, of course, we have to work in any slant of wind that happens to be blowing. The worst condition is a wind from anywhere abaft the beam, blowing at a faster rate than the towing ship is moving through the water. In that case, the balloon simply drifts ahead to the end of its tether, swings around, and gives the ship a tow. If the wind is strong enough—say, forty miles an hour, with the ship doing twenty—to make her give a good steady pull on the cable, it is not so bad; but when it is touch-and-go between ship and wind the poor old 'kite' is all over the shop, and about as difficult to work in as to ride in—which is saying a good deal."
