inch in diameter, and
peeling the bark from the ends an inch or so, proceeded to rub the bark
rapidly with a dry stick peeled perfectly smooth. In a short time the
sap in the twig commenced to exude from both ends. Then placing the
large end between his teeth he pulled suddenly, and the bark slipped off
with a crack in it. Then cutting a small hole in the form of a
parallelogram, near the upper end, he adjusted a stopper with flattened
surface so as to fit exactly the opening. Cutting off the end of the
stopple even with the bark and filling the lower opening nearly full of
clay, he declared the work was done. As a proof of this, he blew into
the hollow tube, and a low, musical sound was emitted, very flute-like
and silvery. When blown harshly, it could be heard at a great distance,
and filled the air with melodious echoes.

Thus equipped, we set out upon our search. The first two days were spent
unsuccessfully. On the third we found ourselves near what is now called
Agate Beach. At this place a small cove indents the land, which sweeps
round in the form of a semi-circle. The shore is literally packed with
agates and crystals. We dug some more than two feet deep in several
places, but still could find no bottom to the glittering floor. They are
of all colors, but the prevailing hues are red and yellow. Here Juan
paused, and lifting his whistle to his lips, he performed a multitude of
soft, gentle airs, which floated across the calm waves like a lover's
serenade breathes o'er the breast of sleeping beauty. It all seemed in
vain. We had now entirely circumnavigated the lake, and were on the eve
of despairing utterly, when suddenly we beheld the surface of the lake,
nearly a quarter of a mile from the shore, disturbed violently, as if
some giant whale were floundering with a harpoon in its side. In a
moment more the head and neck of one of those tremendous serpents that
of late years have infested the lake, were uplifted some ten or fifteen
feet above the surface. Almost at the same instant we beheld the head,
face and hair, as of a human being, emerge quickly from the water, and
look back toward the pursuing foe. The truth flashed upon us
instantaneously. Here was a mermaid pursued by a serpent. On they came,
seemingly regardless of our presence, and had approached to within
twenty yards of the spot where we stood, when suddenly both came to a
dead halt. Juan had never ceased for a moment to blow his tuneful flute,
and it
