"That's the way the Admiral gives his orders to the other ships," volunteered Dick. "You'll notice they run up every set of flags first on the flagship, then the ships behind follow suit, finally when the order is understood by them all and it comes time to do that which the Admiral wants done, down they all go together."
"Jinks! I'd think it a pretty tedious way of sending messages," remarked Donald Barry, watching the gay flags go fluttering upwards in the breeze; "just imagine spelling out all those words. I'd think that sometimes they'd all go ashore or run into each other or something before they half finished what they wanted to say."
Dick, having spent considerable of his spare moments in reading up about naval matters, smiled at Donald and continued his explanation.
"It isn't necessary to spell out the words. Each group of flags means some special command, and all you have to do is to look it up in the signal book as you would a word in the dictionary. Most of the commoner signals become so well known after a little experience that it is only a matter of seconds to catch the meaning."
"I wish we could go on board one of the ships, don't you, fellows?" mused Robert rather irrelevantly. He was generally the silent one of the party, but the lads agreed with him that his wish was a good one. Yet such luck was hardly to be expected.
The flagship was passing but a few yards away, and the watchers could readily see the sailors on her decks all dressed in white working clothes, while on the broad quarter-deck a line of men, uniformed in khaki and armed with rifles, were drawn up in two straight military rows. Near these men glistened the instruments of the ship's band as they stood playing a lively march.
Suddenly the boys heard a sharp command wafted to them over the water. "Haul down!" were the words, and simultaneously from every ship in the column the lines of flags were hauled down to the signal bridges. Then came the splash of anchors, the churning of reversed propellers, the smoke and dust of anchor chains paying out through hawse pipes, and the fleet had come to anchor. Hardly had the great anchors touched the water when long booms swung out from the ships' sides, gangways were lowered, and from their cradles swift launches with steam already up were dropped into the water by huge electric cranes.
"What is the blue flag with all the stars they hoisted at their bows when they stopped?" questioned Donald, turning to Dick as being the best informed member of the party.
"That is the Union Jack," Dick replied, "and they fly that from the jack staff only when a ship is in dock, tied up to a wharf or at anchor; and also, if you noticed, they pulled down the National Ensign from the gaff on the mainmast and hauled another up on the flagstaff astern at the same time. When the flag flies from the gaff it means the ship is under way."
"It certainly is a shame, Dick, you cannot go to Annapolis in my place," remarked Gordon, regretfully; "you already know more than all of us combined about the Navy. But do you know, seeing these ships to-day and the businesslike way they do things has stirred my blood. It is just wonderful! But for the life of me I cannot see how a chap can learn all there is to know about them in only four years. I rather think I shall have to do some pretty hard digging if I ever expect to be a naval officer."
