Chapter 1

An Explosion

"Are you all ready, Tom?"

"All ready, Mr. Sharp," replied a young man, who was stationed near some complicated apparatus, while the questioner, a dark man, with a nervous manner, leaned over a large tank.

"I'm going to turn on the gas now," went on the man. "Look out for yourself. I'm not sure what may happen."

"Neither am I, but I'm ready for it. If it does explode it can't do much damage."

"Oh, I hope it doesn't explode. We've had so much trouble with the airship, I trust nothing goes wrong now."

"Well, turn, on the gas, Mr. Sharp," advised Tom Swift. "I'll watch the pressure gauge, and, if it goes too high, I'll warn you, and you can shut it off."

The man nodded, and, with a small wrench in his hand, went to one end of the tank. The youth, looking anxiously at him, turned his gaze now and then toward a gauge, somewhat like those on steam boilers, which gauge was attached to an aluminum, cigar-shaped affair, about five feet long.

Presently there was a hissing sound in the small frame building where the two were conducting an experiment which meant much to them. The hissing grew louder.

"Be ready to jump," advised Mr. Sharp.

"I will," answered the lad. "But the pressure is going up very slowly.

Maybe you'd better turn on more gas."

"I will. Here she goes! Look out now. You can't tell what is going to happen."

With a sudden hiss, as the powerful gas, under pressure, pa.s.sed from the tank, through the pipes, and into the aluminum container, the hand on the gauge swept past figure after figure on the dial.

"Shut it off!" cried Tom quickly. "It's coming too fast! Shut her off!"

The man sprang to obey the command, and, with nervous fingers, sought to fit the wrench over the nipple of the controlling valve. Then his face seemed to turn white with fear.

"I can't move it!" Mr. Sharp yelled. "It's jammed! I can't shut off the gas! Run! Look out! She'll explode!"

Tom Swift, the young inventor, whose acquaintance some of you have previously made, gave one look at the gauge, and seeing that the pressure was steadily mounting, endeavored to reach, and open, a stop-c.o.c.k, that he might relieve the strain. One trial showed him that the valve there had jammed too, and catching up a roll of blue prints the lad made a dash for the door of the shop. He was not a second behind his companion, and hardly had they pa.s.sed out of the structure before there was a loud explosion which shook the building, and shattered all the windows in it.

Pieces of wood, bits of metal, and a cloud of sawdust and shavings flew out of the door after the man and the youth, and this was followed by a cloud of yellowish smoke.

"Are you hurt, Tom?" cried Mr. Sharp, as he swung around to look back at the place where the hazardous experiment had been conducted.

"Not a bit! How about you?"

"I'm all right. But it was touch and go! Good thing you had the gauge on or we'd never have known when to run. Well, we've made another failure of it," and the man spoke somewhat bitterly.

"Never mind, Mr. Sharp," went on Tom Swift. "I think it will be the last mistake. I see what the trouble is now; and know how to remedy it.

Come on back, and we'll try it again; that is if the tank hasn't blown up."

"No, I guess that's all right. It was the aluminum container that went up, and that's so light it didn't do much damage. But we'd better wait until some of those fumes escape. They're not healthy to breathe."

The cloud of yellowish smoke was slowly rolling away, and the man and lad were approaching the shop, which, in spite of the explosion that had taken place in it, was still intact, when an aged man, coming from a handsome house not far off, called out, "Tom, is anyone hurt?"

"No, dad. We're all right."

"What happened?"

"Well, we had another explosion. We can't seem to get the right mixture of the gas, but I think we've had the last of our bad luck. We're going to try it again. Up to now the gas has been too strong, the tank too weak, or else our valve control is bad."

"Oh dear, Mr. Swift! Do tell them to be careful!" a woman's voice chimed in. "I'm sure something dreadful will happen! This is about the tenth time something has blown up around here, and--"

"It's only the ninth, Mrs. Baggert," interrupted Tom, somewhat indignantly.

"Well, goodness me! Isn't nine almost as bad as ten? There I was, just putting my bread in the oven," went on Mrs. Baggert, the housekeeper, "and I was so startled that I dropped it, and now the dough is all over the kitchen floor. I never saw such a mess."

"I'm sorry," answered the youth, trying not to laugh. "We'll see that it doesn't happen again."

"Yes; that's what you always say," rejoined the motherly-looking woman, who looked after the interests of Mr. Swift's home.

"Well, we mean it this time," retorted the lad. "We see where our mistake was; don't we. Mr. Sharp?"

"I think so," replied the other seriously.

"Come on back, and we'll see what damage was done," proposed Tom.

"Maybe we can rig up another container, mix some fresh gas, and make the final experiment this afternoon."

"Now do be careful," cautioned Mr. Swift, the aged inventor, once more.

"I'm afraid you two have set too hard a task for yourselves this time."

"No we haven't, dad," answered his son. "You'll see us yet skimming along above the clouds."

"Humph! If you go above the clouds I shan't be very likely to see you.

But go slowly, now. Don't blow the place up again."

Mr. Swift went into the house, followed by Mrs. Baggert, who was loudly bewailing the fate of her bread. Tom and Mr. Sharp started toward the shop where they had been working. It was one of several buildings, built for experimental purposes and patent work by Mr. Swift, near his home.

"It didn't do so very much damage," observed Tom, as he peered in through a window, void of all the panes of gla.s.s. "We can start right in."

"Hold on! Wait! Don't try it now!" exclaimed Mr. Sharp, who talked in short, snappy sentences, which, however, said all he meant. "The fumes of that gas aren't good to breathe. Wait, until they have blown away.

It won't be long. It's safer."

He began to cough, choking from the pungent odor, and Tom felt an unpleasant tickling sensation in his throat.

"Take a walk around," advised Mr. Sharp. "I'll be looking over the blue prints. Let's have 'em."
