"h.e.l.lo!" exclaimed Joe, "I wonder what happened then?"
"Come with me and we"ll find out," proposed the man. "I can take you over to the gate house where the diver"s helpers are at work. I"m a member of the town water committee," he went on. "You folks are with the circus, aren"t you?"
"Yes," Joe answered. "But we won"t have much of a crowd at the afternoon show if they all stay here at the reservoir to see the diver rescued."
"That"s right," conceded Mr. Blair, as he said his name was. "But we"ll go and see what happened. I can take you in all right."
They made their way through the crowd, which was thronged as near to the scene of the accident as the men and boys, women and girls, could get. Several constables stood on guard, but at a nod from Mr. Blair they let him pa.s.s, with Joe and Helen.
"Oh, Joe!" she murmured, as she held his arm. "I"m so afraid something dreadful will happen."
"Perhaps not," he answered rea.s.suringly.
They found the men at the pump and the other helpers very much excited, and it was this excitement which had communicated itself to the crowd.
"What happened?" asked Mr. Blair. "Are you getting him up?"
"I only wish we were," wearily said a man who was at the signal line.
"We"ve not been able to move him an inch, and just now he signaled for more air. I"m afraid something has gone wrong down there--I mean something new. Maybe his suit is punctured and he"s being drowned."
"Oh, if we could only do something!" exclaimed Mr. Blair. He stood with Joe, just outside the gate house. On the broad top of the dam, a few feet above the surface of the water, the pumping apparatus was set up.
Near it were the tools used by the diver in the repair work.
Going down into the water was the air hose, through which oxygen was supplied. A few bubbles rising to the surface told that the hose was still connected with the diver"s helmet. In addition to the hose a light but strong line led into the water. A man held this in his hand, and it was by a series of jerks on this that the diver below communicated with his helpers above. Then there was a heavy rope made fast to a ring in the wall. The other end was attached to the diver"s belt.
And these three things--a rope, a line and a hose descending into the mysterious water--were the only links that connected the diver with life. That he was still alive was evident, for now and then there came a feeble pull on the life-line.
Two men had hold of the heavy rope, the end of which was in the diver"s belt, and, from time to time, they pulled on it, hoping that the unfortunate man had been able to free himself, so he could be pulled up.
But the rope remained taut--it did not give. The diver was still caught in the outlet pipe--just how no one could say.
"Can"t they drain the reservoir?" asked Joe. "Surely, to save a life, the towns could do without water for a while."
"Oh, we"d drain it in a minute if we could," said Mr. Blair. "But you see now we can"t get the main outlet pipe open. It"s in that one that the diver is stuck. Only a little water is now flowing through it. We have opened all the small outlets we can, but it will take three or four days to empty the reservoir through them."
"Three or four days," murmured Joe. "And in the meanwhile----"
He did not care to finish the sentence.
Again came a quick signal on the life-line.
"He wants more air!" cried the man who interpreted the jerks. "Give him more air, boys!"
The men at the wheel of the air pump worked it faster. Though why an increased pressure was wanted no one knew.
"Helen," said Joe in a low voice, "I"m going to try to save that man. I can"t bear to stand here and think he may be slowly dying down there,"
and he pointed to the calm water, unruffled save by the few escaping bubbles of air.
"But how can you?" asked the girl. "There isn"t another diving suit to be had here, Joe, even if you were used to one."
"I"ll go down without one!" declared Joe. "In fact, I think I can work better without one than in one. I"m going down and try to save him!"
"Oh, if you only can!" she answered. "It would be great! But you will be careful--won"t you?"
Joe nodded. Helen did not ask him not to go. She knew Joe too well for that. The young circus performer stepped up to Mr. Blair.
"If they"ll let me," said Joe, "I"d like to go down and try to free that diver from whatever is holding him."
"You go down? Are you a diver?"
"Not the kind that uses a suit, no. But I do a diving and tank act in the circus."
Joe"s offer and his talk had aroused instant attention from the crowd about him and from the men at the air pumps and life-line.
"I guess you"ll find, young man, brave and generous as your offer is,"
said one of the air-pumpers, "that diving in a circus tank is some different from going down forty feet."
"I realize that," said Joe quietly.
"And what about holding your breath?" asked Mr. Blair. "Can you do it?"
"He can hold it for nearly four and a half minutes," said Helen quickly.
"Whew!" whistled one of the diver"s helpers. He knew what that record meant.
"If you"ll let me, I"ll go down without a suit," offered Joe. "I"m not saying I can save your man, but I simply can"t stand here and let him die without making an effort."
"Good for you!" cried one of the pump-men. "Some of us tried to go down, but we couldn"t fetch that far, not being able to hold our breath. If you"ll try, it will be the only chance poor Tom has, for he can"t last much longer, and by the time the other diver gets here--well, it"ll be too late, that"s all. Go ahead, young man, and try."
Murmurs of appreciation greeted Joe"s announcement. There was a hurried consultation among the members of the town water committee, of which Mr. Blair was one.
"Shall I go down?" asked Joe.
"Yes!" cried Mr. Blair. "Go, and we"ll all pray that you may be successful," he added solemnly. "It is a terrible thing to stand by and know a fellow being is dying, as Rand may be," and he motioned to the water, still gently agitated by the air bubbles.
Joe Strong lost no time. He was told there were some old clothes in the gate house which he could use, and soon, attired in a pair of trousers cut off short and in an old shirt, he took his place on the reservoir wall just above the spot where the lifeline disappeared in the water.
It was going to be a deep dive, and Joe knew it. And now, if ever, was the time for him to break the record in holding his breath. For he might be able to free the diver in a few seconds, or it might take minutes.
Joe inflated and deflated his lungs several times. The crowd watched him as if fascinated. Helen caught Joe"s glance and nodded encouragingly to him, but there was a look of anxiety on her face.
"If Joe should be caught as the diver is," she thought for a flash. And then she dismissed the dreadful idea, for she dared not dwell on it.
"Well, I"m ready," said Joe, after a pause.
"May you succeed!" whispered Mr. Blair.
Joe took in a long breath--the longest, he felt, he had ever taken.
