"The hull3 of the steamer—that is, the woodwork—will not float itself, but it will sustain considerable additional weight," said he.
"Yes, I understand all that," replied Lawry. "If there had been no iron in the Woodville she would not have gone down."
"The iron in her engines is seven or eight times as heavy as the same bulk of water. Its weight carried the hull down with it."
"Then we must put down empty casks enough to float the engine," added Lawry.
"No; the woodwork of the hull will hold up a portion of the weight of the engine, and we must furnish buoyancy enough to sustain the rest of it."
"It will not take a great many casks, then—will it?"
"Not a great many; but the difficulty is to get them down to the bottom, and fasten them to the hull."
"I can do that," replied Lawry confidently.
Ethan approved the method, and promised to ascertain4 what weight each of the casks would sustain in the water, when he had obtained their dimensions. The ferry-boat reached the other side of the lake, and the young men went to see Mr. Nelson, the owner of the casks. He did not wish to use the hogsheads till October, and was willing they should be employed for the purpose indicated, if Lawry would give him security for their safe return.
"Mr. Sherwood will do that for you, Lawry," said Ethan.
"That's a good name," added the oil speculator. "If he will guarantee the safe return of the casks, that is all I ask. I wonder if Mr. Sherwood don't want some shares in the Meteor Oil Company."
"I don't know; I'll ask him," replied Ethan.
"If you will, I won't charge you anything for the use of the casks," added Mr. Nelson.
Mr. Sherwood was consulted in the evening. He was very willing to furnish the required security for the use of the oil-casks, but he did not seem to have the same confidence in the "Meteor" which Mr. Nelson exhibited, though he promised to consider the matter.
It required three days to complete the preparations for raising the Woodville. All the ropes and rigging in the neighborhood, including many hay-ropes and clothes-lines, had been collected; the oil-casks had been conveyed over the lake in the ferry-boat, and secured within a "boom" composed of four long timbers, lashed5 together at the ends, forming a square, which was moored6 close to the Goblins; and a raft had been built, upon which the operations were to be conducted.
Mr. Sherwood had offered to furnish as many men as could be employed to assist in the work; but the young engineers had so arranged their plans that no help was needed. At sunrise in the morning the boys ran down to the Goblins in the ferry-boat, which was necessary for the transportation of sundry7 heavy articles. The raft was already there, moored in the proper place for commencing the labors9 of the day. The engineers were deeply interested in the operations before them, for there was a difficult problem to be solved, which required all their skill and ingenuity10; and Lawry felt that his future prosperity and happiness depended upon the success of the undertaking11.
Their plans and their machinery12 were yet to be tried, and there was a degree of excitement attending the execution of the project which was as agreeable as it was stimulating13 to their enthusiastic natures. People had laughed at the idea of two boys raising a steamer burdened with heavy machinery, and both of them felt that their reputations were at stake.
"Now, Lawry, we shall soon find out what we can do," said Ethan, as they made fast the ferry-boat to the raft.
"I know what we can do," replied the young pilot confidently. "If the casks will float her, she shall come to the top of the water before to-morrow night. Now, Ethan, the first thing is to get a rope under her."
"That's easy enough."
"It's all easy enough, if you only believe in yourself."
A rope of six fathoms14 in length was selected from the mass of rigging on the raft, and a stone just heavy enough to sink the line attached to the middle of it. Lawry took it in the wherry, sculled to the stern of the sunken steamer, and dropped it into the water. He then carried one end to Ethan, on the raft, while he returned with the other in his boat, which he moored to the opposite side of the Woodville. The middle of the rope was kept on the bottom of the lake by the stone, while the two ends were carried forward by the boys until the bight was drawn15 under the keel of the steamer, as far as her position on the rocks would permit it to go. Lawry's end was made fast around the smokestack, and Ethan's to the raft.
One of the hogsheads was next floated out of the boom enclosure, and hauled upon the raft, Lawry adjusted the hogshead slings16 to the cask. In the middle of the raft an aperture17 had been left, large enough for a hogshead to pass through, over which a small derrick had been built. A stone post, about the length of the casks, and just heavy enough to sink one of them, had been brought down on the bateau. This "sinker," as the young engineers called it, had been weighed, and it exactly conformed to the requirement of Ethan's figures; it was just sufficient to overcome the flotage power of the cask.
"Now, keep cool, Ethan, and we shall find out whether your figures are correct, or not," said Lawry.
"Figures won't lie," replied Ethan; "I know they are correct, and that hogshead will go to the bottom as quick as though it were made of lead."
"We shall soon see," added Lawry, as he placed a couple of skids18 across the "well." "Now we must place the sinker on those skids."
By the aid of the derrick, which was provided with a rude windlass, constructed by Ethan, the stone post was hoisted19 up, and then dropped down on the skids. The sinker had been rigged with slings, and the hogshead was attached to it by a contrivance of Lawry, upon which the success of the operation wholly depended, and which it will be very difficult to describe with words. The sinker would carry the cask to the bottom of the lake, where its buoyancy was to assist in bringing the steamer to the surface of the water; but it was necessary, after the cask had been sunk and fastened to the hull, to detach it from the sinker; and this had been a problem of no little difficulty to Lawry, who managed the nautical21 part of the enterprise.
Fastened to the slings on the sinker was a rope ten fathoms in length. A loop was formed in this line, close to the sinker, and the bight passed through the slings on the hogshead. The loop was then laid over the two ropes, one of which was fast to the sinker, and the other was the unattached end of the line, and "toggled" on with a marline-spike. If the young reader does not quite understand the process, let him take a string, with one end fastened to a flatiron; double it, and pass the loop—which sailors call a bight—upward between the thumb and forefinger22; bring the loop down to meet the two parts of the string on the palm of the hand; then take the two lines into the loop, and put a pencil under the two parts drawn through the loop. The flatiron will correspond to the stone sinker, and the thumb to the slings on the hogshead. Lift up the flatiron, so that the weight will bear on the thumb; then pull out the pencil, and the iron will drop.
The marlinespike was thoroughly23 greased, and a small line attached to the head of it, so that it could be easily drawn out of the loop, when the cask had been secured to the hull of the steamer.
"There, we are all right now," said Lawry, after he had tried the marlinespike several times to satisfy himself that it could be easily drawn from its place. "Now we will make fast the rope which runs under the keel to the hogshead."
"Here it is," added Ethan.
"We want to have the cask under the guard of the steamer when we get it down."
"That will be easy enough."
"If it does, we must take the raft round to the other side of the Woodville, and pass it round the windlass; we can haul it up in that way."
"That will take too much time. I think you and I both will be strong enough to haul the cask into place."
"Now, give us a turn at the windlass, Ethan," said Lawry, when he was ready.
"Aye, aye," replied Ethan, as he turned the crank, and raised the sinker and the cask, so that the skids which supported them could be removed.
"Lower away!" added Lawry, highly excited; and the sinker began to descend25 into the water, carrying with it the hogshead. "That works first-rate. Now hold on till I get hold of the other end of the guide-rope."
Lawry jumped into the wherry, and sculled round to the other side of the sunken steamer, where he detached the end of the line passing under the keel from the smoke-stack, where it had been secured. He hauled on the rope till he got it clear of the stone with which it had been sunk.
"Lower away!" shouted Lawry.
"Lower, it is," answered Ethan.
"Slowly," added the pilot, as he hauled in the rope.
"It is going to the right place. I can see it in the water."
"Hold on!" cried Lawry; and the wherry was so unsteady beneath him that it was with great difficulty he "kept what he had got" on the rope.
In order to overcome this disadvantage he passed the rope around the smokestack.
"I have it now!" shouted he. "This gives me a splendid purchase;" and he hauled in the rope, bringing the hogshead chock up to the hull of the sunken craft.
"We are growing wiser every moment," laughed Ethan.
"So we are. Lower away, slowly. That's it," said Lawry. "Lower away."
"The sinker is on the bottom," replied Ethan.
"All right; can you see the hogshead?"
"Yes; you have hauled it completely under the guard. The water is as clear as crystal," answered Ethan.
"Hold on a moment till I make fast this line!"
Thus far the experiment had been entirely26 successful, and Lawry's bosom27 bounded with emotion. The plan for raising the Woodville was his own, though he had been greatly assisted by Ethan, who had designed and constructed the derrick and windlass, thus diminishing the labor8 of the enterprise. The young pilot felt like a conqueror28 when he had placed the first cask in position.
Sculling the wherry back to the raft, he pulled the string attached to the toggle, and drew it out of the noose29.
"Hoist, it is," replied Ethan, as he took hold with him.
"All right!" shouted the young nautical engineer. "I feel like giving three cheers," he added.
"So do I; and we'll do it, when we get the sinker on the raft."
The stone post came up "in good order and condition," and the skids were placed under it, to keep it in position for the sinking of the second hogshead. The three cheers were given with a will, and they came from the hearts of the boys. They had labored30 patiently for three days in gathering31 the material and constructing the machinery for the raising of the steamer, and their first success was a real joy.
"Breakfast-time," said Lawry, as the horn sounded from the ferry-house.
"I don't want any breakfast," answered Ethan. "I don't feel as though we could spare the time for eating."
"Haste and waste," added Lawry, laughing. "We have got a great deal of hard work to do, and we must keep our strength. For my part, I'm hungry."
"I'm not; and I'm so interested in this job that I don't like to leave. We ought to have brought our breakfast down with us."
"I don't think we shall make anything by driving the work too hard. We must keep cool, and do it well. Besides, I'm liable to be called off a dozen times a day."
"What for?"
"To take people over the ferry."
"Oh, bother!" exclaimed Ethan impatiently. "Have we got to leave the work to paddle everybody that comes along over the lake?"
"We have," said Lawry. "I must look out for the family now."
There was a good wind, and the boys returned to the ferry-house in the bateau. Before they had finished their breakfast, the ferry-horn sounded, and Lawry was obliged to take a team over to Pointville before the work could be resumed. Ethan was rather impatient under this delay; but he was too kind-hearted to make any unpleasant remark which would remind his friend of his father's crime.
