Horace grinned at him from his perch.

"I invented it," he said. "I got the idea from the fourth proposition of Euclid."

"What circus he with?"

"He's dead."

"Well, he must of broke his neck doin' that stunt. I set here last night thinkin' sure you was goin' to break yours."

"Like this!" said Horace, and swinging onto the trapeze he did his stunt.

"Don't it kill your neck an' shoulder muscles?"

"It did at first, but inside of a week I wrote the QUOD ERAT DEMONSTRANDUM on it."

"Hm!"

Horace swung idly on the trapeze.

"Ever think of takin' it up professionally?" asked the fat man.

"Not I."

"Good money in it if you're willin' to do stunts like 'at an' can get away with it."

"Here's another," chirped Horace eagerly, and the fat man's mouth dropped suddenly agape as he watched this pink-jerseyed Prometheus again defy the G.o.ds and Isaac Newton.

The night following this encounter Horace got home from work to find a rather pale Marcia stretched out on the sofa waiting for him.

"I fainted twice to-day," she began without preliminaries.

"What?"

"Yep. You see baby's due in four months now. Doctor says I ought to have quit dancing two weeks ago."

Horace sat down and thought it over.

"I'm glad of course," he said pensively--"I mean glad that we're going to have a baby. But this means a lot of expense."

"I've got two hundred and fifty in the bank," said Marcia hopefully, "and two weeks' pay coming."

Horace computed quickly.

"Inducing my salary, that'll give us nearly fourteen hundred for the next six months."

Marcia looked blue.

"That all? Course I can get a job singing somewhere this month.

And I can go to work again in March."

"Of course nothing!" said Horace gruffly. "You'll stay right here. Let's see now--there'll be doctor's bills and a nurse, besides the maid: We've got to have some more money."

"Well," said Marcia wearily, "I don't know where it's coming from. It's up to the old head now. Shoulders is out of business."

Horace rose and pulled on his coat.

"Where are you going?"

"I've got an idea," he answered. "I'll be right back."

Ten minutes later as he headed down the street toward Skipper's Gymnasium he felt a placid wonder, quite unmixed with humor, at what he was going to do. How he would have gaped at himself a year before! How every one would have gaped! But when you opened your door at the rap of life you let in many things.

The gymnasium was brightly lit, and when his eyes became accustomed to the glare he found the meditative fat man seated on a pile of canvas mats smoking a big cigar.

"Say," began Horace directly, "were you in earnest last night when you said I could make money on my trapeze stunts?"

"Why, yes," said the fat man in surprise.

"Well, I've been thinking it over, and I believe I'd like to try it. I could work at night and on Sat.u.r.day afternoons--and regularly if the pay is high enough."

The fat men looked at his watch.

"Well," he said, "Charlie Paulson's the man to see. He'll book you inside of four days, once he sees you work out. He won't be in now, but I'll get hold of him for to-morrow night."

The fat man was as good as his word. Charlie Paulson arrived next night and put in a wondrous hour watching the prodigy swap through the air in amazing parabolas, and on the night following he brought two age men with him who looked as though they had been born smoking black cigars and talking about money in low, pa.s.sionate voices. Then on the succeeding Sat.u.r.day Horace Tarbox's torso made its first professional appearance in a gymnastic exhibition at the Coleman Street Gardens. But though the audience numbered nearly five thousand people, Horace felt no nervousness. From his childhood he had read papers to audiences--learned that trick of detaching himself.

"Marcia," he said cheerfully later that same night, "I think we're out of the woods. Paulson thinks he can get me an opening at the Hippodrome, and that means an all-winter engagement. The Hippodrome you know, is a big---"

"Yes, I believe I've heard of it," interrupted Marcia, "but I want to know about this stunt you're doing. It isn't any spectacular suicide, is it?"

"It's nothing," said Horace quietly. "But if you can think of an nicer way of a man killing himself than taking a risk for you, why that's the way I want to die."

Marcia reached up and wound both arms tightly round his neck.

"Kiss me," she whispered, "and call me 'dear heart.' I love to hear you say 'dear heart.' And bring me a book to read to-morrow.

No more Sam Pepys, but something trick and trashy. I've been wild for something to do all day. I felt like writing letters, but I didn't have anybody to write to."

"Write to me," said Horace. "I'll read them."

"I wish I could," breathed Marcia. "If I knew words enough I could write you the longest love-letter in the world--and never get tired."

But after two more months Marcia grew very tired indeed, and for a row of nights it was a very anxious, weary-looking young athlete who walked out before the Hippodrome crowd. Then there were two days when his place was taken by a young man who wore pale blue instead of white, and got very little applause. But after the two days Horace appeared again, and those who sat close to the stage remarked an expression of beatific happiness on that young acrobat's face even when he was twisting breathlessly in the air an the middle of his amazing and original shoulder swing. After that performance he laughed at the elevator man and dashed up the stairs to the flat five steps at a time--and then tiptoed very carefully into a quiet room.

"Marcia," he whispered.

"h.e.l.lo!" She smiled up at him wanly. "Horace, there's something I want you to do. Look in my top bureau drawer and you'll find a big stack of paper. It's a book--sort of--Horace. I wrote it down in these last three months while I've been laid up. I wish you'd take it to that Peter Boyce Wendell who put my letter in his paper. He could tell you whether it'd be a good book. I wrote it just the way I talk, just the way I wrote that letter to him.

It's just a story about a lot of things that happened to me. Will you take it to him, Horace?"

"Yes, darling."
