Undine nodded emphatically. "It's the thing I like to do best of
anything in the world. Do you like it? Oh, yes, of course you do. You
call yourself the Sunfish on that account."

Sahwah affirmed her love for the deep, and thrilled a little at
discovering an enthusiasm to match hers in this girl from Honolulu. The
rest of the Winnebagos, although good swimmers, did not possess in an
equal degree Sahwah's inborn passion for the water. Sahwah and Undine
both felt the call of the river as it flowed past the dock; to each of
them it beckoned with an irresistible invitation, until they could
hardly restrain themselves from leaping off the boards into the cool,
glassy depths below.

"Here comes Miss Armstrong!" shouted somebody at the other end of the
dock, as the big Australian came into view down the path, and there was
a scramble for the diving tower.

The swimming place at Camp Keewaydin was divided into three parts. A
shallow cove at the left of the dock, where the curve of the river
formed a tiny bay, was the sporting ground of the Minnows, the girls who
could not swim at all; the Perch, or those who could swim a little, but
were not yet sure of themselves, were assigned to the other side of the
dock, where the water was slightly deeper, but where they were protected

expert swimmers, were given the freedom of the river beyond the end of
the pier. The diving tower was on the end of the pier and belonged
exclusively to the Sharks; it was fifteen feet high, and had seven
different diving boards placed at various heights. Besides the diving
tower, there was a floating dock anchored out in midstream, having a
