It was not until then that most of Joe's fellow performers heard about his feat, and it made a great sensation.

"Why didn't you save that act for the circus?" asked Jim Tracy. "It would have made a big hit and brought a crowd."

"I didn't have time to stage it properly," Joe said. "I was thinking of saving myself a fine for being late at the show."

But an unusually big crowd came to the show anyhow, brought by having read of Joe's thrilling ride. He was a sort of center of attraction as he went through his trapeze and tank acts.

Unexpected and impulsive as Joe's ride was, it formed the forerunner of what was afterward a big feature in his life, as will appear in due time.

For a week or more the circus moved along its mapped-out route, and nothing of moment occurred. The usual crowds came and went, the performers went through their acts successfully, and Joe and his trained seal did their turns to the great amus.e.m.e.nt and entertainment of the audiences, as well as satisfaction to the circus management. The swimming of Joe and the seal, the showy goldfish and the general setting of the act made it a most novel one.

"Is there any more word from Benny?" asked Helen one day.

"Nothing definite," Joe said. "He is still in the same condition. I have written to the doctor to make inquiries and find out if there is, in this country or abroad, any new means of treatment that could be given. Often foreign doctors know things those over here haven't heard of yet."

"Oh, I do hope they discover something," sighed Helen. "Poor Benny! I feel so sorry for him!"

The circus grounds in the town of Westford were located near a great reservoir which supplied water to several neighboring munic.i.p.alities.

And Westford was reached by the Sampson Brothers' Show about two weeks after Joe's sensational ride on the trestle.

After breakfast Joe and Helen strolled about the grounds, and having seen that the performing horse and the gla.s.s tank had reached the grounds safely, Joe proposed that he and Helen go for a little motor-cycle ride.

"But you'll have to promise not to take me over any railroad trestles,"

Helen warned him.

"I'll promise," agreed Joe.

They did not go far, and on their way back, as they pa.s.sed the reservoir, they saw a big crowd gathered on the bank near a gate-house.

"Looks as if something was going on," said Joe, stopping the machine.

"Maybe some one is rivaling you in a high diving stunt," said Helen, half playfully.

They alighted and made their way into the throng.

"What's up?" asked Joe of a man.

"A diver is caught down in the outlet pipe," was the unexpected answer.

"A diver!" repeated Joe.

"Yes. A man in a diving suit went down to fix something that went wrong with one of the valves, and they can't get him up. He's been down several hours now and they're afraid he's dead!"

CHAPTER XXII

A DEEP DIVE

"What is it?" asked Helen, who had not understood what Joe's informant had said.

"It's a diver caught down at the mouth of the outlet pipe of the reservoir," the man explained. "They're trying to get him up but they don't seem to get him."

"Why not?" Joe wanted to know.

"Because they can't pull any harder on the life line than they have been pulling for fear either of breaking the line or of injuring the diver. And they have to be careful, too, of fouling his air hose. If that breaks it would be death for him."

"How terrible!" exclaimed Helen. "Can nothing be done to save him?"

"They're trying everything they can think of, Miss," was the man's answer. "The water company has sent for another diver to go down and see what the trouble is, but it will be half a day before he can get here, and by that time----"

He did not finish, but Joe and Helen knew what was meant.

The big crowd about the reservoir was excited, and yet it was a tense, quiet sort of excitement. It was a grim waiting for what might, at any moment, happen. Either the diver would be hauled up, or he would perish deep down there under the calm water.

"How did it happen?" asked Joe. The man seemed to know considerable about the accident.

"It was this way," he replied. "The reservoir is a new one, and it hasn't worked just right since the water was let in. That is, the main supply pipe, by which the water goes out to other and smaller pipes to be distributed to the different munic.i.p.alities, gets clogged up every now and then.

"At first they thought it was because some refuse matter, left on the ground when the reservoir was built, had gotten into the valves. But a diver went down and found there was something the matter with the valves themselves. They open and close the valves from the gate house over there," and he indicated it, standing on the main dam wall of the big reservoir.

"After the diver found what was wrong," the man went on, "the water concern planned to have it fixed, and for some days now the work has been going on. The diver would go down, his tools would be lowered to him, and he has been working under water. You see they don't want to let the water out of the reservoir because it would leave some towns without a supply, which would be dangerous, if even for a day.

"So the diver has been working down there, and it's pretty deep, too, about forty feet. There's a good deal of pressure at that depth, though of course divers have gone deeper."

"Yes," a.s.sented Joe. "And how did the accident happen?"

"n.o.body knows, exactly. Tom Rand, the diver, went down as usual this morning, and his tools were let down to him. But he hadn't been down long, as I understand it, before he signaled to be hauled up. He signaled in a hurry, too, so something must have happened.

"The men at the air pump and the helpers tried to get him up, but they couldn't. He was stuck down there, and, as I said, they don't dare pull too hard for fear of cutting him in two, making a hole in the diving suit, or breaking the rope. They don't know what to do."

"Why, this is terrible!" exclaimed Helen.

"Yes, Miss, it certainly is. To think of that poor man, caught down under the water in some way and not able to be got up. Of course he can breathe, for the air hose is still working, and the men are at the pump constantly. But it's impossible to stand that pressure very long at a time, and he'll soon give out from exhaustion, if nothing else happens.

They've sent for another diver, but, as I said, he'll be some time getting here, and then it may be too late."

"Isn't there another diving suit to be had?" asked Joe.

"No," the man answered.

Helen looked at Joe. She read the thought that was in his mind.

"Did you ever go down in a diving suit?" she asked him in a low voice.

"No, but I'd take a chance if they had one. However, as there isn't I can't. But perhaps----"

Joe was interrupted by a shout from the crowd. He and Helen, with the man who had been giving them the information, stood a little to one side.
