them and Haven Point, where the railroad station was located. Here they found the town people in great excitement, and learned that steps were already being taken to care for any of the workmen who might be injured by the explosions.

“Of course we have no idea yet how many people have been killed or wounded,” declared a policeman who gave the cadets this information. “We are all upset because we don’t know how bad the explosions may get. If they don’t get any worse than they have been, we’ll be thankful.”

The cadets and their girl friends did not remain long in Haven Point. All were anxious to get to Clearwater Hall, to learn if that place was much damaged. The girls’ school was directly opposite the shell-loading plant, and consequently more liable to suffer than the town or Colby Hall.

“Look at them getting away from that place, will you?” cried Fred, who had come as far as Haven Point on another automobile and then had rejoined his cousins. He pointed to the lake, where a number of rowboats and other craft were leaving the vicinity of the explosions.

“You can’t blame them for wanting to get away,” returned Jack. “It may mean life or death to them.”

“Oh, I hope nobody has been killed!” murmured Ruth.

“I’m afraid, Ruth, that’s too much to expect,” answered Jack soberly.

“Oh, I just think war is too horrible for anything!” cried out Alice Strobell, who was along.

“I just wish they could sink all those Germans in their old submarines!” declared Annie Larkins who was also in the crowd.

“I guess we’d all be willing to subscribe to that!” cried Randy.

“You just wait until Uncle Sam gets into this scrap,” declared Jack. “We’ll show ’em what’s what!”

“How I wish I could go to the front,” said Andy wistfully. “It would beat going to school all hollow.”

“Now that we’ve gone into the war, we’ll have an army over there before long,” said Spouter. “I suppose they’ll send some of the regulars over first, and then some of the national guard—of course taken into the regular army—and after that we’ll have the volunteers. I suppose if Uncle Sam really wanted to do it, he could get together several million men without half trying. And with an army like that, properly trained and equipped, and transported to the battlefields of Europe, we shall be sure to make a showing which will throw terror into the hearts of——”

“Hurrah! Spouter is off again,” broke in Randy.

“Say, Spout! they ought to send you to the front to help talk the Huns to death,” put in Andy. “Talk about gas and gas masks——”

“Aw say! you’re always butting in when I’ve got something to say,” growled the lad who loved to talk.

There might have been a little friction right then and there, but another explosion came from across Clearwater Lake, and all stopped to gaze at the thick volume of yellowish-black smoke which rolled directly toward them.

“The wind must be shifting,” declared Jack, for all of the smoke heretofore had rolled up the lake shore.

“It’s too bad it is coming this way,” said Ruth. “Miss Garwood declares that a good deal of smoke from such shells is poisonous.” Miss Garwood was the head of the school for girls, and likewise an authority in chemistry.

The road was filled with automobiles going and coming, and Randy had all he could do to send the machine along without getting into some sort of collision. The heavy smoke continued to roll across the lake, and soon they were in the midst of this. It had a curious pungent odor to it, which set them to sneezing and coughing.

“No fun in this, I must say,” declared Jack. The girls all had their handkerchiefs to their faces, and May Powell looked as if she was getting sick.

In a minute more they came within sight of Clearwater Hall, a large structure setting back in well-kept grounds. There were numerous bushes and flowers and quite a number of fair-sized trees.

Several automobiles had reached the school ahead of them so the scene was one of animation. Town people, as well as scholars from the Hixley High School, mingled with the cadets and the girls from Clearwater Hall.

“Go on in and find Mary,” said Jack to his sister. “Tell her we are here to help her in case anything happens.”

Martha rushed off, followed by Ruth, and the two soon located Fred’s sister. She was in a rear room of the school, along with a number of the other pupils and one of the assistant teachers.

“Oh, I’m so glad you’ve come!” declared Mary Rover. “What a dreadful thing this is getting to be!”

“I suppose it has made your head ache worse than ever,” said Martha sympathetically.

“No, strange to say, it’s just the other way around,” declared Fred’s sister, with a faint smile. “Those explosions seemed to have shocked the headache all away.”

Mary was glad to join the others, and the Rovers and their friends proceeded to one of the reception rooms of the school. In the meantime the explosions across the lake continued, but seemed to be gradually dying down.

“It looks to me as if the worst was over,” remarked Fred, after there had been comparative silence for fully a quarter of an hour.

“Say, I’m going down to the lake front to see what’s doing,” declared Randy, a little later. “Perhaps we can be of some assistance.”

“That’s the talk! We can’t do anything more here,” returned his twin.

“Let’s all go down!” cried Jack. “We ought to be able to do something for those poor workmen who have been hurt.” And then, turning to Ruth, he continued: “If there are any more big explosions and this place seems to be in danger, we’ll be back.”

“Oh, Jack! I don’t want you to run into any danger down at the lake shore,” said the girl, looking at him pleadingly with her big brown eyes.

“I guess we’ll be able to take care of ourselves,” he answered lightly. But it pleased him a great deal to have Ruth so full of consideration for him.

Leaving their automobiles in the school grounds, the Rovers and their chums left the place, crossed the highway, and followed the footpath leading down to the Clearwater Hall boathouse. Here they found only a few people congregated, the heavy-rolling clouds of smoke keeping a good many away.

“Not very pleasant here,” was Gif Garrison’s comment, after the smoke had made him cough. “I don’t think I’m going to stay.”

“Neither am I,” said Spouter. And presently he and quite a few others left, leaving the four Rovers to themselves.

“You know what I’ve got an idea of doing?” declared Jack. “Why not get out one of the Clearwater Hall boats and row over a little closer to that place? We may be able to be of some assistance to some of the workmen.”

The others were willing, and soon a large rowboat was brought out, with two pairs of oars, and the four Rovers manned it and sent it well out into the lake.

“We’ve got to keep our eyes open in this smoke,” declared Jack. “It’s worse than a fog.”

“You’re right there,” returned Randy. “If some of those poor chaps——”

Boom!

Another terrific explosion cut short what he was saying. The very water under the rowboat seemed to shake, and the air presently was filled with flying missiles dropping all around them. Then, as Andy stood up in an endeavor to get a better view of the situation, something came flying through the air, hit him on the shoulder, and hurled him overboard!
