CHAPTER XXVIII.
THE MISDIRECTED ENERGIES OF MR. BRADLEY.
Mr. Bradley, our inventor, has had some experiences in addition to those already recorded which may perhaps be entertaining to the reader. One of the peculiarities of Bradley's contrivances is that when they are designed to do a specified work, that is conspicuously the work they cannot possibly be induced to do. There, for instance, was Bradley's famous steam-pump.
Some years ago Bradley invented a steam-pump for use on shipboard. He claimed for it that it would pump about three times as many gallons in a minute as any other pump, and he got some of his political friends in Congress to use their influence with the Navy Department to have it tried on one of the navy vessels. Finally he succeeded in having it introduced upon a small steamer, which we will call the Water Witch; and when everything was ready, the ship started upon a trial trip. Soon after she got to sea, Bradley, who was aboard, said he would like to try the pump upon the bilge-water to see how she worked.
The captain ordered the engineer to turn it on, and the machine operated apparently in the most beautiful manner. In about an hour one of the officers reported that the water was gaining rapidly in the hold, and the captain sent some men down to discover where the leak was. They came back and reported that they couldn't find the hole, but that the water was pouring in somewhere in frightful quantities.
Then some of the officers went down and spent half an hour in water up to their waists feeling around after that awful hole, but they couldn't ascertain where it was. The only thing that they were certain of was that the water was steadily gaining on them, and the ship was certain to sink unless something was done. All this time Mr. Bradley's pump was working away, and the captain continually enjoined the engineer to give it greater speed.
Then the captain himself went down and made an examination; and although he failed to find the leak, he was alarmed to discover a quantity of codfish and porpoises swimming about in the hold, because he knew that the hole in the hull must be very large indeed to admit the fish. And still the water rose steadily all the time, although Bradley's pump was jerking away at it in a terrific manner and all the other pumps were running at full speed.
At last the captain made up his mind that he should have to desert the ship, as she was certain to sink; and so the boats were made ready and packed with provisions and water and a few little comforts, and by this time the water in the bilge was nearly up to the furnace fires.
Just then Bradley's pump suddenly stopped; and then the captain turned pale as death and demanded to know who stopped that pump, while Bradley buckled a life-preserver around him, corked up a note to his wife in a bottle, and said that now that the pump had ceased he would give that steamer just four minutes to reach bottom.
While he was speaking the engineer came up and said,
"Mr. Bradley, what did you say was the capacity of your pump?"
"Six hundred gallons a minute."
"Six hundred. Well, Mr. Bradley, how many gallons do you estimate that there are in the Atlantic Ocean?"
"Blessed if I know. How in the mischief can I tell that?"
"Oh, it don't make any particular difference, only I thought you might have some kind of an indistinct idea how long it would take you to run the ocean through your pump."
"I dunno, I'm sure," said Bradley.
"Well, I merely wanted to say that, whatever your calculations respecting the number of gallons in the Atlantic, it is perfectly useless for you to try to load up that ocean in this vessel. She won't hold more'n half of it."
"What do you mean, sir?" demanded Bradley.
"Why, I mean that that diabolical pump of yours, instead of taking out the bilge, has been spurting water into this vessel for the past four hours, and that if you have a theory that you can strike dry land by that process it is ingenious, but it won't work, for it's going to sink this ship."
Then the captain swore till the air was blue. Then he put Bradley in irons, and ripped out his pump, and unpacked the boats, and pumped out the water, and picked up the codfish and porpoises, and set sail for home for the purpose of making a report on the subject of the new invention. The Bradley Improved Marine Steam-pump went right out of use at the end of the voyage.
Another invention of Bradley's was a scientific system of foretelling the weather. He had a lot of barometers, hygrometers and such things in his house, and he claimed that by reading these intelligently and watching the clouds, in accordance with his theory, a man could prophesy what kind of weather there would be three days ahead. They were getting up a Sunday-school picnic in town in May; and as Bradley ascertained that there would be no rain on a certain Thursday, they selected that day for the purpose. The sky looked gloomy when they started; but as Bradley declared that it absolutely couldn't rain on Thursday, everybody felt that it was safe to go. About two hours after the party reached the grounds, however, a shower came up, and it rained so hard that it ruined all the provisions, wet everybody to the skin and washed the cake into dough. On the following Monday the agricultural exhibition was to be held; but as Mr. Bradley foresaw that there would be a terrible north-east storm on that day, he suggested to the president of the society that it had better be postponed. So they put it off; and that was the only clear Monday we had during May. About the first of June, Mr. Bradley announced that there would not be any rain until the 15th; and consequently we had showers everyday right along up to that time, with the exception of the 10th when there was a slight spit of snow. So on the 15th, Bradley foresaw that the rest of the month would be wet; and by an odd coincidence a drought set in and it only rained once during the two weeks, and that was the day on which Bradley informed the base-ball club that it could play a match, because it would be clear.
On toward the first of July he began to have some doubts if his improved weather-system was correct; he was convinced that it must work by contraries. So when Professor Jones asked him if it would be safe to attempt to have a display of fireworks on the night of the 5th, Bradley brought the improved system into play, and discovered that it promised rainy weather on that night. So then he was certain it would be clear; and he told Professor Jones to go ahead.
On the night of the 5th, just as the professor got his Catherine-wheels and sky-rockets all in position, it began to rain; and that was the most awful storm we had that year: it raised the river nearly three feet. As soon as it began Bradley got the axe and went up stairs and smashed his hydrometers, hygrometers, barometers and thermometers. Then he cut down the pole that upheld the weathercock and burned the manuscript of the book which he was writing in explanation of his system. He leans on "Old Probs" now when he wants to ascertain the probable state of the weather.

When his first baby was born, Bradley invented a self-rocking cradle for it. He constructed the motive-power of the machine from some old clockwork which was operated by a huge steel ribbon spring strong enough to move a horse-car and long enough to run for a week without rewinding. When the cradle was completed, he put the baby in it upon a pillow and started the machinery. It worked beautifully, and after watching it for a while Bradley went to bed in a peaceful and happy frame of mind. Toward midnight he heard something go r-r-r-rip! Buzz-z-z-z! Crash! Bang! Then a pin or something of the kind in the clockwork gave way, and before Bradley could get out of bed the cradle containing the baby was making ninety revolutions a minute, and hopping around the room and slamming up against the furniture in a manner that was simply awful to look at.
[Illustration: BRADLEY'S CRADLE]
How to get the child out was now the only consideration which presented itself to the mind of the inventor. A happy thought struck him. He took a slat out of the bedstead and held it under the cradle. On the next down-stroke it stopped with a jerk, and the baby was thrown, like a stone out of a catapult, against the washstand, fortunately with the pillow to break its fall. But the machine kept whizzing round and round the room as soon as the slat was withdrawn, and Bradley, in an ecstasy of rage, flung it out the back window into the yard. It continued to make such a clatter there that he had to go down and pile up barrels and slop-buckets and bricks and clothes-props and part of the grape-arbor on it, so that all it could do was to lie there all night buzzing with a kind of smothered hum and keeping the next-door neighbors awake, so that they pelted it with bootjacks, under the impression that it was cats.
Mrs. Bradley expressed such decided views respecting cradles of that pattern that Mr. Bradley turned his attention to other matters than those of a domestic character. He resolved to revolutionize navigation. It occurred to him that some kind of an apparatus might be devised by which a man could walk upon the surface of the water, and he went to work at it. The result was that in a few weeks he produced and patented Bradley's Water Perambulator. It consisted of a couple of shallow scows, each about four feet long. These were to be fastened to the feet; and Bradley informed his friends that with a little practice a man could glide over the bosom of a river with the ease and velocity with which a good skater skims over the ice.
It looked like a splendid thing. Bradley said that it would certainly produce a revolution in navigation, and make men wholly independent of steamers and other vessels when they desired to travel upon water with rapidity. Bradley intimated that the day would come when a man would mount a water perambulator and go drifting off to India, sliding over the bounding billows of the dark blue sea as serenely as if he were walking along a turnpike.
And one day Bradley asked a select party to come down to the river to see him make a trial-trip. At the appointed time he appeared with something that looked like a small frigate under each arm; and when he had fastened them securely upon his feet, he prepared to lower himself over the edge of the wharf. He asked the spectators to designate a point upon the thither shore at which they wished him to land. It was immaterial to him, he said, whether he went one mile or ten, up stream or down, because he should glide around upon the surface of the stream with the ease and grace of a swallow. Then they fixed a point for him; and when he had dropped into the water, he steadied himself for a moment by holding to the pier while he fastened his eye upon his destination and prepared to start.
At last he said the experiment would begin; and he struck out with his left foot. As he did so the front end of that particular scow scuttled under water, and as he tried to save himself by bringing forward his right foot, that section of Bradley's Water Perambulator also dipped under, and Bradley fell.
[Illustration: THE NEW MOTOR]
A moment later he was hanging head downward in the river, with nothing visible to the anxious spectators but the bottoms of two four-foot frigates. The perambulator simply kept the body of Bradley under the water. Then a man went out in a skiff and pulled the inventor in with a boat-hook. When he came ashore, they unbuckled his scows, took off his clothing and rolled him upon an oil-barrel. In half an hour he revived, and with a deep groan he said,
"Where am I?"
His friends explained his situation to him, and then he asked,
"What drowned me?"
They told him sadly that he was injured during an attempt to revolutionize navigation and to prepare the way for a walk to India.
"How did I try to do it?" he inquired.
They wept as they reminded him that he had started to skim over the river like a swallow, with a scow upon each foot, and then he faintly said,
"Where in thunder are those machines?"
His friends produced, the new motor with which Bradley intended to break up the steamship lines; and when he had looked at them for a moment, he fell back and whispered,
"It's no use. I can't do 'em justice. Eight men couldn't cuss 'em to satisfy me. But split 'em up! Have 'em mashed into kin'lin-wood before I get well, or the sight of 'em'll set me crazy."
Then he was carried home, and after being in bed about a fortnight he came out with a pallid cheek, a sorrowful heart and ideas for six or seven new machines.
