Boy Scouts in the Philippines Part 13

"Well," Pat observed, "whoever it is that is doing the business, there are traitors in the secret service department. The Americans who acted with the Filipinos who captured us are posted as to what is going on at Washington, all right."

"Let's go and get them," suggested Jimmie. "I guess the third degree would make them tell all about it!"

"Yes," suggested Pat, "you run out and get them while we find the _Manhattan_! That will be a nice little job for you!"

"I wouldn't let them tie me up, anyway," growled Jimmie, annoyed at the chaffing of his friends. "Say!" he added, "here's our little bay now, but where is that bloomin' motor boat? Some one's come and carried it away while we've been in the woods, an' took Jack and Frank away with it!"

CHAPTER VIII.

WIGWAGS FROM THE BEACH.

For a long time after the departure of Ned, Jack and Frank sat in the cabin of the _Manhattan_, looking out on the steady downpour. They were not quite satisfied with their share in the activities of the day.

Instead of being housed in the cabin, they preferred an exciting hunt even in the rain, over the hills of the little island in view.

"If we stand for it," grumbled Jack, "we'll have to spend most of our time keeping house! Jimmie will scatter himself all over the Asiatic division of the map, and Ned will spend most of his time looking him up!"

Frank laughed at this outbreak of ill humor, although he was as anxious as his chum to be on the firing line.

"I wish we'd not taken the _Manhattan_," Jack continued. "I'm the only one in the party that can operate it, and I'll be tied down like a galley slave!"

"Go it!" laughed Frank. "Growl your head off, if you want to, Mr. Black Bear! Instead of snarling, why don't you tell me what makes the boat go when you do something to the wheel and that switch?"

"I thought you owned a launch?" said Jack.

"Father bought me one," was the reply, "but I've never learned how to run it. I'm too fat to bother my head about such things!"

"Then what are you asking me about the mechanism of the thing for?"

asked Jack. "If you don't want to know, what's the use of my telling you how to run a motor boat? You make me weary!"

"If I had a nice little temper like yours," Frank grinned, "I'd go and b.u.mp my head against a tree! Come, old man, tell me about the boat. I may want to run it some time, after you get caught by a cat or filled full of poisoned arrows! Come! honest! What makes it go?"

"And you don't even know the action of a gasoline engine?" exclaimed Jack, in better humor. "Well, I'll tell you. A jet of gasoline, which is thinner than water, is sprayed, as one would spray any liquid from an atomizer, into the chamber of the engine cylinder-head, which it reaches in the form of vapor, having been mixed with air."

"That's all simple!"

"Here the vapor is compressed by the rising piston, and when it is squeezed up as close as it can be an electric spark is introduced into the chamber. That is what the electric battery and gear are for."

"I was wondering why one had to have electricity and gasoline both,"

said Frank, very much interested in the simple recital.

"The result of the introduction of the spark is the explosion of the compressed vapor, which sends the piston downward. The motion turns the shaft, and that turns the boat's propeller."

"Easy as pie."

"This operation is repeated from two to six hundred times a minute,"

Jack went on, "and that causes the continuous action of the machinery which sends the boat along."

"What is there about that so complicated?" demanded Frank. "Everybody you hear talking of an engine seems to speak as if it were one of the mysteries of the universe."

"It is usually the electric system which gets out of order," was the reply, "but sometimes the gasoline section balks. A man often has to try so many different things when his engine stops that he actually does not know which one remedies the evil and sets the thing in motion."

"All right!" Frank said. "Now show me how to start the thing."

"That's easy. First turn on your gasoline, as you would turn water from a faucet into a kitchen sink. The gasoline fills the carbureter, which is the thing which feeds the engine automatically. Then you turn on your electricity by shifting a switch. That is to supply the spark. Then turn the fly-wheel two or three times so as to get the vapor into the cylinder and secure the first explosion. That is all there is to it. I hope you do learn to run this boat, so I can get away now and then!"

"You may get away farther than you want to!" cautioned Frank.

The _Manhattan_ was a plain, usable boat, twenty-five feet long and ten feet wide, with bow and stern rather square in order to make more room inside. The cabin was ten feet long, with strong oak sides and bra.s.s-rimmed ports for light and ventilation. The c.o.c.kpit, or outdoor sitting room, was of the same length as the cabin.

The engine was a plain, solidly built machine, with two cylinders, and rated at ten horsepower, with a speed of fifteen miles an hour. It was installed under a short bridge-deck in front of the cabin, while the gasoline tanks, holding fifty gallons, were hidden under the c.o.c.kpit seats.

The cabin had two wide slatted berths, supplied with hair mattresses, a movable table, an ice chest, a small coal range--the boat was not designed especially for tropical use--an ice-chest and an alcohol stove for cooking. The storage lockers and water tanks had a capacity of a week's supply of stores for four persons. It was a government boat, and was in good repute as a racer in and about Manila, in spite of its blunt bow and wide beam.

Frank pottered away at the machinery until he announced that it was like taking candy away from the children to run it, and then the two retired to the cabin to get rid of their wet garments.

"Ned and Jimmie are having a good soaking," Jack said, his ill humor all gone, as he soused his wet underclothing in a tub of sea water. "I wish they'd come home."

A dull thump, as of a canoe striking the motor boat, and a quick step on the prow caused both boys to spring to their feet.

"There they come now!" Jack cried, glancing out into the slanting rain, "and it's good and wet they are."

The boy was about to step forward and open the cabin door when Frank caught him by the shoulder.

"Wait!" he said. "Look there!"

Jack followed the pointing finger with his eyes and saw half a dozen Filipinos clambering into the c.o.c.kpit, and also saw the muzzles of American-built rifles covering the cabin door.

"Get your gun!" Jack whispered.

"We've got to do something besides shoot," Frank said. "They have the drop on us. We should have been looking out for an attempt at surprise."

There was a moment's silence, and then a man enveloped from neck to heels in a heavy raincoat and sweating tremendously in consequence, advanced to the cabin door.

"Never mind the guns!" he said, through the gla.s.s. "My men have you covered, and it would be a pity to shoot two likely boys!"

"What do you want?" demanded Frank.

"We want this boat," was the reply.

"Well, you've got it!" Jack said, angrily.

"Of course we have," was the reply. "We seem to be getting about everything we want in this corner of the world! Where are the others?"

"Gone after a battleship!" declared Jack.
