subject, "and we'll do stunts on the trapeze."

Isabel and Doctor Jack sat side by side on a battered old trunk in stony
silence while the twins were donning their gymnasium costumes.
Fortunately, it did not take long and the sight of Juliet hanging by her
feet furnished the needed topic of conversation. The lithe little body
seemed to be made of steel fibres. She swayed back and forth, catching
Romeo as he made a flying leap from the other trapeze, as easily as
another girl would have wielded a tennis racquet.

At length Doctor Jack interposed a friendly word of warning. "Look here,
kid," he said, "you're made of flesh and blood, you know, just like the
rest of us. Better cut out that trapeze business."

"I don't know why," returned Juliet, resentfully, as she slipped
gracefully to the floor, right side up. "I'm as strong as Romie is, or
almost as strong."

"Girls do it in the circus," Romeo observed, wiping his flushed face.

"Ever heard of any of 'em living to celebrate their hundredth birthday?"
queried Doctor Jack, significantly.

The twins admitted that they had not. "I don't care," cried Juliet, "I'd
rather live ten years and keep going, than live to be a hundred and have
to sit still all the time."

"No danger of your sitting still too long," returned Doctor Jack, good-
humouredly. "It's hot up here, isn't it?"
