“All right, Harry?” asked Joe of one of the riggers who had charge of putting up the platforms and the big swing.

“Sure, it’s all right, Mr. Strong!” was the answer.  “I should say so!  I don’t make no mistakes when I’m putting up trapezes.  You’ll find everything shipshape and proper.  Going to have a big crowd to-day, I guess.”

Joe looked at Harry Loper closely.  The young man had never talked so much before, being, on the whole, rather close-mouthed.  As the man passed Joe, after giving a pull on the last rope, the young magician became aware that Harry had been drinking—­and something stronger than pink lemonade.

“I’m sorry about that!” mused Joe, as the rope rigger passed on.  “If there’s any place a man ought not to drink it’s in a circus, and especially when he has to rig up high flying apparatus for others.  It was drink that put Bill Carfax out of business.  I didn’t know Harry was that kind, I never noticed it before.  I’m sorry.  And I’ll take extra precautions that my ropes won’t slip.  You can’t trust a man who drinks.”

Joe shook his head a bit sadly.  He was thinking of Bill Carfax, and of the fact that he had had to discharge the man because, while under the influence of liquor, he had insulted Helen.  Then Bill had tried to get revenge on Joe.

“I hope it doesn’t turn out this way with Harry Loper,” mused Joe, as he began climbing up a rope ladder that led to one of the high platforms.  And as Harry had to do with the placing of this ladder, Joe tested it carefully before ascending.

“I don’t want to fall and be laid up in the middle of the circus season,” mused the young circus man, with a frown.

However, the ladder appeared to be perfectly secure, and as Joe went up, finally reaching the high platform, he felt a sense of exhilaration.  Heights always affected him this way.  He liked, more than anything else, to soar aloft on his Wings of Steel.  And he liked the sensation when he leaped from one platform toward the swinging trapeze bar, aiming to grasp it in his hands and swing in a great arc to the other little elevated place, close under the top of the tent.

There was a thrill about it—­a thrill not only to the performer but to the audience as well—­and Joe could hear the gasps that went up from thousands of throats as he made his big swing.

But, for the time being, he gave his whole attention to the platform and its fastenings.  The platforms were not very likely to slip, being caught on to the main tent poles, which themselves were well braced.

The real danger was in the long trapeze.  Not only must the thin wire ropes of this be strong enough to hold Joe’s weight, but an added pressure, caused by the momentum of his jump.  And not only must the cables be strong, but there must be no defect in the wooden bar and in the place where the upper ends of the ropes were fastened to the top of the tent.

“Well, this platform is all right,” remarked Joe, as he looked it over.  “Now for the other and the trapeze.”
