An Appeal For Aid

Tom Swift stepped from the door of the machine shop, where he was at work making some adjustments to the motor of his airship, and glanced down the road. He saw a cloud of dust, which effectually concealed whatever was causing it.

"Some one must be in a hurry this morning," the lad remarked, "Looks like a motor speeding along. My! but we certainly do need rain," he added, as he looked up toward the sky. "It's very dusty. Well, I may as well get back to work. I'll take the airship out for a flight this afternoon, if the wind dies down a bit."

The young inventor, for Tom Swift himself had built the airship, as well as several other crafts for swift locomotion, turned to reenter the shop.

Something about the approaching cloud of dust, however, held his attention. He glanced more intently at it.

"If it's an automobile coming along," he murmured, "it's moving very slowly, to make so much fuss. And I never saw a motor-cycle that would kick up as much sand, and not speed along more. It ought to be here by now. I wonder what it can be?"

The cloud of highway dirt rolled along, making some progress toward Tom's house and the group of shops and other buildings surrounding it. But, as the lad had said, the dust did not move at all quickly in comparison to any of the speedy machines that might be causing it. And the cloud seemed momentarily to grow thicker and thicker.

"I wonder if it could be a miniature tornado, or a cyclone or whirlwind?" and Tom spoke aloud, a habit of his when he was thinking, and had no one to talk to. "Yet it can hardly be that." he went on. "Guess I'll watch and see what it is."

Nearer and nearer came the dust cloud. Tom peered anxiously ahead, a puzzled look on his face. A few seconds later there came from the midst of the obscuring cloud a voice, exclaiming:

"G'lang there now, Boomerang! Keep to' feet a-movin' an' we sho' will make a record. 'Tain't laik we was a autermobiler, er a electricity car, but we sho' hab been goin' sence we started. Yo' sho' done yo'se'f proud t'day, Boomerang, an' I'se gwine t' keep mah promise an' gib yo' de bestest oats I kin find. Ah reckon Massa Tom Swift will done say we brought dis yeah message t' him as quick as anybody could."

Then there followed the sound of hoofbeats on the dusty road, and the rattle of some many-jointed vehicle, with loose springs and looser wheels.

"Eradicate Sampson!" exclaimed Tom. "But who would ever think that the colored man's mule could get up such speed as that cloud of dust indicates. His mule's feet must be working overtime, but he goes backward about as often as he moves forward. That accounts for it. There's lots of dust, but not much motion."

Once more, from the midst of the ball-like cloud of dirt came the voice of the colored man:

"Now behave yo'se'f, Boomerang. We'm almost dere an' den yo' kin sit down an' rest if yo' laik. Jest keep it up a little longer, an' we'll gib Massa Tom his telephone. G'lang now, Boomerang."

The tattoo of hoofbeats was slowing up now, and the cloud of dust was not so heavy. It was gradually blowing away. Tom Swift walked down to the fence that separated the house, grounds and shops from the road. As he got there the sounds of the mule's progress, and the rattle of the wagon, suddenly ceased.

"G'lang! G'lang! Don't yo' dare t' stop now, when we am most dere!" cried Eradicate Sampson. "Keep a-movin', Boomerang!"

"It's all right, Eradicate. I'm here," called Tom, and when the last of the dust had blown away, the lad waved his hand to an aged colored man, who sat upon the seat of perhaps the most dilapidated wagon that was ever dignified by such a name. It was held together with bits of wire, rope and strings, and each of the four wheels leaned out at a different angle. It was drawn by a big mule, whose bones seemed protruding through his skin, but that fact evidently worried him but little, for now the animal was placidly sleeping, while standing up, his long ears moving slowly to and fro.

"Am dat yo', Massa Tom?" asked Eradicate, ceasing his task of jerking on the lines, to which operation the mule paid not the least attention.

"Yes, I'm here, Rad," replied Tom, smiling. "I came out of my shop to see what all the excitement was about. How did you ever get your mule to make so much dust?"

"I done promise him an extra helpin' ob oats ef he make good time," said the colored man. "An' he done it, too. Did yo' see de dust we made?"

"I sure did, but you didn't do much else. And you didn't make very good time. I watched you, and you came along like an ice wagon after a day's work on the Fourth of July. You were going fast, but moving slow."

"I 'spects we was, Massa Tom," was the colored man's answer. "But Boomerang done better dan I 'spected he would. I done tole him yo'd be in a hurry t' git yo' telephone, an' he sho' did trot along."

"My telephone?" repeated Tom, wonderingly. "What have you and your mule Boomerang to do with my telephone? That's up in the house."

"No, it ain't! it's right yeah in mah pocket," chuckled Eradicate, opening a ragged coat, and reaching for something. "I got yo' telephone right yeah." he went on. "De agent at de station see me dribin' ober dis way, an' he done ast he t' deliber it. He said as how he ain't got no messenger boy now, 'cause de one he done hab went on a strike fo' five cents mo' a day. So I done took de telephone," and with that the colored man pulled out a crumpled yellow envelope.

"Oh, you mean a telegram," said Tom, with a laugh, as he took the message from the odd colored man.

"Well, maybe it's telegraf, but I done understood de agent t' say telephone. Anyhow, dere it is. An' I s'pects we'd better git along, Boomerang."

The mule never moved, though Eradicate yanked on the reins, and used a splintered whip with energy.

"I said as how we'd better git along, Boomerang," went on the darkey, raising his voice, "Dinnah am mos' ready, an' I'm goin' t' giv yo' an extra helpin' ob oats."

The effect of these words seemed magical. The mule suddenly came to life, and was about to start off.

"I done thought dat would cotch yo', Boomerang," chuckled Eradicate.

"Wait a minute, Rad," called Tom, who was tearing open the envelope of the telegram. "I might want to send an answer back by you. I wonder who is wiring me now?"

He read the message slowly, and Eradicate remarked:

"'Taint no kind ob use, Massa Tom, fo' t' send a message back wif me."

"Why not?" asked the young inventor, looking up from the sheet of yellow paper.

"'Case as how I done promised Boomerang his airman, an' he won't do nothin' till he has it. Ef I started him back t' town now he would jest lay down in de road. I'll take de answer back fo' you dis arternoon."

"All right, perhaps that will do," assented Tom. "I haven't quite got the hang of this yet. Drop around this afternoon, Rad," and as the colored man, who, with his mule Boomerang, did odd jobs around the village, started off down the highway, in another cloud of dust, Tom Swift resumed the reading of the message.

"Hum, this is rather queer," he mused, when having read it once, he began at it again. "It must have cost him something to send all this over the wire. He could just as well have written it. So he wants my help, eh? Well, I never heard of him, and he may be all right, but I had other plans, and I don't know whether I can spare the time to go to Philadelphia or not. I'll have to think it over. An electric airship, eh? He's sort of following along the lines of my inventions. Wants my aid—hum—well, I don't know—"

Tom's musings were suddenly cut short by the approach of an elderly gentleman, who was walking slowly down the path that led from the house to the country highway which ran in front of it.

"A telegram, Tom?" asked the newcomer.

"Yes, dad," was the reply. "I was just coming in to ask your advice about it. Eradicate brought it to me."

"What, with his mule, Boomerang?" and the gentleman seemed much amused. "How did he ever get up speed enough to deliver a telegram?"

"Oh, Eradicate has some special means he uses on his mule when he's in a hurry. But listen to this message, dad. It's from a Mr. Hosmer Fenwick, of Philadelphia. He says:"

"'Tom Swift—Can you come on to Philadelphia at once and aid me in perfecting my new electric airship? I want to get it ready for a flight before some government experts who have promised to purchase several if it works well. I am in trouble, and I can't get it to rise off the ground. I need help. I have heard about your airship, and the other inventions you and your father have perfected, and I am sure you can aid me. I am stuck. Can you hurry to the Quaker City? I will pay you well. Answer at once!'"

"Well?" remarked Mr. Swift, questioningly, as his son finished reading the telegram. "What are you going to do about it, Tom?"

"I don't exactly know, dad. I was going to ask your advice. What would you do? Who is this Mr. Fenwick?"

"Well, he is an inventor of some note, but he has had many failures. I have not heard of him in some years until now. He is a gentleman of wealth, and can be relied upon to do just as he says. We are slightly acquainted. Perhaps it would be well to aid him, if you can spare the time. Not that you need the money, but inventors should be mutually helpful. If you feel like going to Philadelphia, and aiding him in getting his electric airship in shape, you have my permission."

"I don't know," answered Tom, doubtfully. "I was just getting my monoplane in shape for a little flight. It was nothing particular, though. Dad, I think I will take a run to Philadelphia, and see if I can help Mr. Fenwick. I'll wire him that I am coming, to-morrow or next day."

"Very well," assented Mr. Swift, and then he and his son went into one of the shops, talking of a new invention which they were about to patent.

Tom little knew what a strange series of adventures were to follow his decision to go to the Quaker City, nor the danger involved in aiding Mr. Fenwick to operate his electric airship.

Chapter II Miss Nestor's News

"When do you think you will go to Philadelphia, Tom?" asked Mr. Swift, a little later, as the aged inventor and his son were looking over some blueprints which Garret Jackson, an engineer employed by them, had spread out on a table.

"I don't exactly know," was the answer. "It's quite a little run from Shopton, because I can't get a through train. But I think I'll start to-morrow."

"Why do you go by train?" asked Mr. Jackson.

"Why—er—because—" was Tom's rather hesitating reply. "How else would I go?"

"Your monoplane would be a good deal quicker, and you wouldn't have to change cars," said the engineer. "That is if you don't want to take out the big airship. Why don't you go in the monoplane?"

"By Jove! I believe I will!" exclaimed Tom. "I never thought of that, though it's a wonder I didn't. I'll not take the Red Cloud, as she's too hard to handle alone. But the Butterfly will be just the thing," and Tom looked over to where a new monoplane rested on the three bicycle wheels which formed part of its landing frame. "I haven't had it out since I mended the left wing tip," he went on, "and it will also be a good chance to test my new rudder. I believe I will go to Philadelphia by the Butterfly."

"Well, as long as that's settled, suppose you give us your views on this new form of storage battery," suggested Mr. Swift, with a fond glance at his son, for Tom's opinion was considered valuable in matters electrical, as those of you, who have read the previous books in this series, well know.

The little group in the machine shop was soon deep in the discussion of ohms, amperes, volts and currents, and, for a time, Tom almost forgot the message calling him to Philadelphia.

Taking advantage of the momentary lull in the activities of the young inventor, I will tell my readers something about him, so that those who have no previous introduction to him may feel that he is a friend.

Tom Swift lived with his father, Barton Swift, a widower, in the village of Shopton, New York. There was also in the household Mrs. Baggert, the aged housekeeper, who looked after Tom almost like a mother. Garret Jackson, an engineer and general helper, also lived with the Swifts.

Eradicate Sampson might also be called a retainer of the family, for though the aged colored man and his mule Boomerang did odd work about the village, they were more often employed by Tom and his father than by any one else. Eradicate was so called because, as he said, he "eradicated" the dirt. He did whitewashing, made gardens, and did anything else that was needed. Boomerang was thus named by his owner, because, as Eradicate said, "yo' nebber know jest what dat mule am goin' t' do next. He may go forward or he may go backward, jest laik them Australian boomerangs."

There was another valued friend of the family, Wakefield Damon by name, to whom the reader will be introduced in due course. And then there was Mary Nestor, about whom I prefer to let Tom tell you himself, for he might be jealous if I talked too much about her.

In the first book of this series, called "Tom Swift and His Motor-Cycle," there was told how he became possessed of the machine, after it had nearly killed Mr. Damon, who was learning to ride it. Mr. Damon, who had a habit of "blessing" everything from his collar button to his shoe laces, did not "bless" the motor-cycle after it tried to climb a tree with him; and he sold it to Tom very cheaply. Tom repaired it, invented some new attachments for it, and had a number of adventures on it. Not the least of these was trailing after a gang of scoundrels who tried to get possession of a valuable patent model belonging to Mr. Swift.

Our second book, called "Tom Swift and His Motor-Boat," related some exciting times following the acquisition by the young inventor of a speedy craft which the thieves of the patent model had stolen. In the boat Tom raced with Andy Foger, a town bully, and beat him. Tom also took out on pleasure trips his chum, Ned Newton, who worked in a Shopton bank, and the two had fine times together. Need I also say that Mary Nestor also had trips in the motor-boat? Besides some other stirring adventures in his speedy craft Tom rescued, from a burning balloon that fell into the lake, the aeronaut, John Sharp. Later Mr. Sharp and Tom built an airship, called the Red Cloud, in which they had some strenuous times.

Their adventures in this craft of the air form the basis for the third book of the series, entitled "Tom Swift and His Airship." In the Red Cloud, Tom and his friends, including Mr. Damon, started to make a record flight. They left Shopton the night when the bank vault was blown open, and seventy-five thousand dollars stolen.

Because of evidence given by Andy Foger, and his father, suspicion pointed to Tom and his friends as the robbers, and they were pursued. But they turned the tables by capturing the real burglars, and defeating the mean plans of the Fogers.

Not satisfied with having mastered the air Tom and his father turned their attention to the water. Mr. Swift perfected a new type of craft, and in the fourth book of the series, called "Tom Swift and His Submarine," you may read how he went after a sunken treasure. The party had many adventures, and were in no little danger from their enemies before they reached the wreck with its store of gold.

The fifth book of the series, named "Tom Swift and His Electrical Runabout," told how Tom built the speediest car on the road, and won a prize with it, and also saved a bank from ruin.

Tom had to struggle against odds, not only in his inventive work, but because of the meanness of jealous enemies, including Andy Foger, who seemed to bear our hero a grudge of long standing. Even though Tom had, more than once, thrashed Andy well, the bully was always seeking a chance to play some mean trick on the young inventor. Sometimes he succeeded, but more often the tables were effectually turned.

It was now some time since Tom had won the prize in his electric car and, in the meanwhile he had built himself a smaller airship, or, rather, monoplane, named the Butterfly. In it he made several successful trips about the country, and gave exhibitions at numerous aviation meets; once winning a valuable prize for an altitude flight. In one trip he had met with a slight accident, and the monoplane had only just been repaired after this when he received the message summoning him to Philadelphia.

"Well, Tom," remarked his father that afternoon, "if you are going to the Quaker City, to see Mr. Fenwick to-morrow, you'd better be getting ready. Have you wired him that you will come?"

"No, I haven't, dad," was the reply. "I'll get a message ready at once, and when Eradicate comes back I'll have him take it to the telegraph office."

"I wouldn't do that, Tom."

"Do what?"

"Trust it to Eradicate. He means all right, but there's no telling when that mule of his may lie down in the road, and go to sleep. Then your message won't get off, and Mr. Fenwick may be anxiously waiting for it. I wouldn't like to offend him, for, though he and I have not met in some years, yet I would be glad if you could do him a favor. Why not take the message yourself?"

"Guess I will, dad. I'll run over to Mansburg in my electric car, and send the message from there. It will go quicker, and, besides, I want to get some piano wire to strengthen the wings of my monoplane."

"All right, Tom, and when you telegraph to Mr. Fenwick, give him my regards, and say that I hope his airship will be a success. So it's an electric one, eh? I wonder how it works? But you can tell me when you come back."

"I will, dad. Mr. Jackson, will you help me charge the batteries of my car? I think they need replenishing. Then I'll get right along to Mansburg."

Mansburg was a good-sized city some miles from the village of Shopton, and Tom and his father had frequent business there.

The young inventor and the engineer soon had the electric car in readiness for a swift run, for the charging of the batteries could be done in much less than the time usual for such an operation, owing to a new system perfected by Tom. The latter was soon speeding along the road, wondering what sort of an airship Mr. Fenwick would prove to have, and whether or not it could be made to fly.

"It's easy enough to build an airship," mused Tom, "but the difficulty is to get them off the ground, and keep them there." He knew, for there had been several failures with his monoplane before it rose like a bird and sailed over the tree-tops.

The lad was just entering the town, and had turned around a corner, twisting about to pass a milk wagon, when he suddenly saw, darting out directly in the path of his car, a young lady.

"Look out!" yelled Tom, ringing his electric gong, at the same time shutting off the current, and jamming on the powerful brakes.

There was a momentary scream of terror from the girl, and then, as she looked at Tom, she exclaimed:

"Why, Tom Swift! What are you trying to do? Run me down?"

"Mary—Miss Nestor!" ejaculated our hero, in some confusion.

He had brought his car to a stop, and had thrown open the door, alighting on the crossing, while a little knot of curious people gathered about.

"I didn't see you," went on the lad. "I came from behind the milk wagon, and—"

"It was my fault," Miss Nestor hastened to add. "I, too, was waiting for the milk wagon to pass, and when it got out of my way, I darted around the end of it, without looking to see if anything else was coming. I should have been more careful, but I'm so excited that I hardly know what I'm doing."

"Excited? What's the matter?" asked Tom, for he saw that his friend was not her usual calm self. "Has anything happened, Mary?"

"Oh, I've such news to tell you!" she exclaimed.

"Then get in here, and we'll go on." advised Tom. "We are collecting a crowd. Come and take a ride; that is if you have time."

"Of course I have," the girl said, with a little blush, which Tom thought made her look all the prettier. "Then we can talk. But where are you going?"
