Scout got word of the equipment that he himself must bring.

"And mind, now, no extras," said Durland, warningly. "If the weather is at all hot, it's going to be hard work carrying all we must carry, and we don't want any Scouts to have to drop out on the march because their knapsacks are too heavy. We will camp by ourselves, and we will keep to ourselves, except when we're on duty. Remember that I, as commander of the Troop, take rank only as a National Guard captain, and that I am subject to the orders of every major and other field officer who may be present.

"Some of the militiamen and their officers may be inclined to play tricks, and to tease us, but the best way to stop them is to pay no attention to them at all. Now, I want every boy to go home and spend the time he can spare before the start studying all the Scout rules, and brushing up his memory on scoutcraft and campcraft. Polish up your drill manual, too. That may be useful. We want to present a good appearance when we get out there with the soldiers."

The start for the camp of the State militia, who were to gather under the command of Brigadier-General Harkness at a small village near the State line, called Guernsey, was to be made on Sunday. The Scouts would be in camp Sunday night, ready at the first notes of the general reveille on Monday morning to turn out and do their part in the work of defending their State against the invasion of the Blue Army, under General Bliss, of the rival State.

"You see," said Jack, explaining matters to Pete Stubbs and Tom Binns as they went home together after the meeting, "we are classed as the Red Army, and we are supposed to be on the defensive. The Blue Army will try to capture the State capital, and it is our business to defeat them if possible."

"How can they tell whether we beat them or not, if we don't do any fighting?" asked Tom Binns.

"In this sort of fighting it's all worked out by theory, just as if it were a game of chess, Tom, and there are umpires to decide every point that comes up."

"How do they decide things, Jack?"

"Why, they ride over the whole scene of operations, either on horseback, or, if the field is very extensive, in automobiles. If troops are surrounded, they are supposed to be captured, and they are sent to the rear, and required to keep out of all the operations that follow. Then the umpires, who are high officers in the regular army, decide according to the positions that are taken which side has the best chance of success. That is, if two brigades, of different sides, line up for action, and get into the best tactical positions possible, the umpires decide which of them would win if they were really engaged in a true war, and the side that gets their decision is supposed to win. The other brigade is beaten, or destroyed, as the case may be."

"Then how about the whole affair?"

"Well, each commanding general works out his strategy, and does his best to bring about a winning position, just as they would at chess, as I said. There is a time limit, you see, and when the time is up the umpires get together, inspect the whole theatre of war, and make their decision."

"It's a regular game, isn't it, Jack?"

"Yes. The Germans call it Krug-spiel—which means war-game, and that term has been adopted all over the world. It's played with maps and pins, too, in the war colleges, both for sea and land, and that's how officers get training for war in time of peace. It isn't an easy game to learn, either."

"Where do we come in, Jack? What is it we're supposed to do?"

"Obey orders, in the first place, absolutely. And I don't know what the orders will be, and neither does anyone else, so I can't tell you just what we'll do. But, generally speaking, we'll just have to do regular scout duty. It will be up to us to detect the movements of the enemy, and report, through Scout-Master Durland, who'll be Captain Durland, during the maneuvers, to the staff."

"General Harkness's staff, you mean, Jack? Just what is a staff, anyhow?"

"The headquarters staff during a campaign is a sort of extra supply of arms and legs and eyes for the commanding general. The staff officers carry his orders, and represent him in different parts of the field. They carry orders, and receive reports, and they take just as much routine work as possible off the hands of the general, so that he'll be free to make his plans. You see the general never does any actual fighting. He's too valuable to risk his life that way. He's supposed to stay behind, and be ready to take advantage of any chance he sees."

"Times have changed, haven't they, Jack? In the old histories we used to read about generals who led charges and did all sorts of things like that."

"Well, it would be pretty wasteful to put a general in danger that way now, Pete. He's had plenty of chance to prove his bravery, as a rule, and, when he's a general, and has years of experience behind him, the idea is to use his brain. If he is in the rear, and by his eyes and the reports he gets in all sorts of ways, can get a general view of what is going on, he can tell just what is best to be done. Sometimes the only way to win a battle is to sacrifice a whole brigade or a division—to let it be cut to pieces, without a chance to save itself, in order that the rest of the army may have time to change its position, so that the battle can be won. That's the sort of thing the general has got to decide, and if he's in the thick of the fighting in the old-fashioned way, he can't possibly do that."

"I think it's going to be great sport, don't you, Jack?" asked Tom Binns. "Will there be any real firing?"

"Yes—with smokeless powder, because they want to test some new kinds. But they'll use blank cartridges, of course. There'll be just as much noise as ever, but there won't be any danger, of course."

"I don't like the sound of firing much," said Tom Binns, a little shamefacedly. "Even when I know it's perfectly safe and that there aren't any bullets, it makes me awfully nervous."

"This will be good practice for you, then, Tom, because it will help you to get used to it. I hope we'll never have another war, but we want to be ready if we ever do. 'Be prepared'—that's our Scout motto, you know, and it means for the things that we might have to do in war, as well as the regular peaceful things that come up every day."

"Will there be any aeroplanes?" asked Pete Stubbs. "I'm crazy to see one of those things flying sometime, Jack. I never saw one yet, except that time when the fellow landed here and hurt himself. And I didn't see him in the air, but only after he made his landing. The machine was all busted up then, too."

"I think there'll be some aeroplane scouting by the signal corps. Several of the men in that are pretty well off, you know, and they have their own flying machines. I guess that's one of the things they'll try to determine in these maneuvers, the actual, practical usefulness of aeroplanes, and whether biplanes or monoplanes are the best."

"Say, Jack, why couldn't we Boy Scouts build an aeroplane sometime? If we learned something about them this next week, I should think we might be able to do something like that. I know a lot of fellows that have made experiments with toy ones, that wind up with a spring that's made out of rubber bands. They see how far they will fly."

"I think that would be great sport, Pete. But we won't have any time for that until after we've been through the maneuvers. But I'll tell you what some of us may get a chance to do next week, though it's a good deal of a secret yet."

"What's that, Jack! We'll promise not to say a word about it, won't we, Tom?"

"You bet we won't, Jack! Tell us—do!" pleaded Tom Binns.

"I guess it's all right for me to tell you if you won't let it go any further. Well, it's just this. They're going to do a lot of experimenting with a new sort of automobile for scout duty, and I think some of us will get a chance with them."

"Gee, I wish I knew how to
