Part 13 (1/2)
He reasoned that as the well rose and overflowed when its outlet was stopped, it might rise yet farther if it were still confined; for its source was probably in the heart of one of the surrounding hills, and water when confined will always rise as high as its source. Therefore, after much meditation as to how it could be accomplished in the simplest and least expensive manner, he set about it as follows.
First of all he cleared away the floor about the well, and built up the circular wall of it a foot or two higher, with stones picked from those lying about, and with mortar which he made himself. By means of a spirit-level, he laid the top layer of stones quite horizontal; and he introduced into it several blocks of wood instead of stones.
Next he made a small wooden frame, which, by driving spikes between the stones, he fastened to the opening of the underground pa.s.sage, so that a well-fitting piece of board could move up and down in it, by means of a projecting handle, and be a more manageable sluice than he had hitherto had.
Then he made a strong wooden lid to the mouth of the well, and screwed it down to the wooden blocks he had built in. Through a hole in it, just large enough, came the handle of the sluice.
Next, in the middle of the cover, he made a hole with a brace and centre-bit, and into it drove the end of a strong iron pipe, fitting tight, and long enough to reach almost to the top of the vault. As soon as this was fixed he shut down the sluice, and in a few seconds the water was falling in sheets upon him, and flooding the floor, dashed back from the vault, against which it rushed from the top of the pipe.
This was enough for the present; he raised the sluice and let the water escape again below. It was plain, from the force with which the water struck the vault, that it would yet rise much higher.
He scrambled now on the top of the vault, and, examining the ruins, soon saw how a pipe brought up through the breach in the vault could be led to the hole in the wall of his room which he had shown his father as a ventilator. But he would not have a close pipe running through his room.
There would be little good in that. He could have made a hole in it, with a stopper, to let the water out when he wanted to use it, but that would be awkward, while all the pleasure lay in seeing the water as it ran. Therefore he got Mr Spelman to find him a long small pine tree, which he first sawed in two, lengthways, and hollowed into two troughs; then, by laying the small end of one into the wide end of the other, he had a spout long enough to reach across the room, and go through the wall on both sides.
The chief difficulty was to pierce the other wall, for the mortar was very hard. The stones, however, just there were not very large, and, with Sandy's help, he managed it.
The large end of one trough was put through the ventilator-hole, and the small end of the other through the hole opposite; their second ends met in the middle, the one lying into the other, and were supported at the juncture by a prop.
They filled up the two openings round the ends with lime and small stones, making them as tidy as they could, and fitting small slides by which Willie could close up the pa.s.sages for the water when he pleased.
Nothing remained but to solder a lead pipe into the top of the iron one, guide this flexible tube across the ups and downs of the ruins, and lay the end of it into the trough.
At length Willie took his stand at the sluice, and told Sandy to scramble up to the end of the lead pipe, and shout when the water began to pour into the trough. His object was to find how far the sluice required to be shut down in order to send up just as much water as the pipe could deliver. More than that would cause a pressure which might strain, and perhaps burst, their apparatus.
He pushed the sluice down a little, and waited a moment.
”Is it coming yet, Sandy?” he cried.
”Not a drop,” shouted Sandy.
Willie pushed it a little further, and then knew by the change in the gurgle below that the water was rising in the well; and it soon began to spout from the hole in the cover through which the sluice-handle came up.
”It's coming,” cried Sandy, after a pause; ”not much, though.”
Down went the sluice a little further still.
”It's pouring,” echoed the voice of Sandy amongst the ruins; ”as much as ever the pipe can give. Its mouth is quite full.”
Willie raised the sluice a little.
”How is it now?” he bawled.
”Less,” cried Sandy.
So Willie pushed it back to where it had been last, and made a notch in the handle to know the right place again.
So the water from the Prior's Well went careering through Willie's bed-chamber, a story high. When he wanted to fill his bath, he had only to stop the run with his hand, and it poured over the sides into it; so that Tibbie was to be henceforth relieved of a great labour, while Willie's eyes were to be delighted with the vision, and his ears with the sounds of the water scampering through his room.
