Curlytops had taught their pet.

Again the audience clapped and laughed. But there was more to come. Tip
and Top did the tricks for which they were famous, separately and
together, one dog walking on his hind legs, and the other turning
somersaults. Then one dog got on the other's back, the two going around
the stage together. And as a climax they did the trick by which Ted and
Janet had recognized their pets in Professor Montelli's tent, one dog
leaping over the other's back, while moving along.

"Now, Jan, you do your trick with the white mice and the alligator while
Harry Kent and I fix up the tower for Jack to jump from," said Ted. "And
Jack can do his clown tricks, too."

It had been decided that while Teddy and his helper were putting in
place the tower for the monkey to leap from something must be done to
amuse the audience.

So Janet had said she would do some little tricks with the mice, rats,
and alligator, while Harry, the fat little boy clown, would turn
somersaults and handsprings on the stage.

This went off very well. Janet fixed the slanting board for Slider to
coast "down hill," and when the alligator had done this the audience
laughed its hardest. Then some of the rats and mice did simple tricks,
two of the larger rats pulling a little toy wagon in which rode two mice.

However, these pets did not do as well as the others, for the two in the
wagon kept jumping out and Janet had to keep putting them back.

Jack, the fat little clown, made a big "hit." He was really very funny,
and when, toward the end of his act, he got too near the edge of the
stage and fell into the lap of big Oscar North, the audience thought it
was all part of the show, and not an accident, and clapped most loudly.
However, Jack was not hurt, and only laughed at the mishap.

By this time the tower was ready. It reached nearly to the top of the
tent, and as the boxes had been covered with green branches they made a
nice appearance.

"Up, Jack! Up!" called Ted, climbing up the stepladder and placing the
banana on top of the tower. Then Ted had to hurry the ladder away, after
Jack had climbed up to the top, for fear the monkey would climb down that
same way instead of jumping as he was wanted to do.

Ted and Harry Kent held the net at the foot of the tower. This time the
net was not a lace curtain, but some old bags sewed together. Janet held
up the bit of banana, and, after he had eaten the piece on top of his
perch, the m
