were no longer there.

Despite all my watchfulness, that day I saw no more of them as I
passed along the streets. From that time on, indeed, neither my old
servant nor I saw them again before the house, nor did I encounter
them elsewhere. Their appearance, however, was stamped upon my
memory, I would not forget them.

Perhaps after all, admitting that I had been the object of their
espionage, they had been mistaken in my identity. Having obtained a
good look at me, they now followed me no more. So in the end, I came
to regard this matter as of no more importance than the letter with
the initials, M. o. W.

Then, on the twenty-fourth of June, there came a new event, to
further stimulate both my interest and that of the general public in
the previous mysteries of the automobile and the boat. The Washington
Evening Star published the following account, which was next morning
copied by every paper in the country.

"Lake Kirdall in Kansas, forty miles west of Topeka, is little known.
It deserves wider knowledge, and doubtless will have it hereafter,
for attention is now drawn to it in a very remarkable way.

"This lake, deep among the mountains, appears to have no outlet. What

"Lake Kirdall is in many places fifty feet deep close to shore.
Sharp, pointed rocks form the edges of this huge basin. Its surges,
roused by high winds, beat upon its banks with fury, and the houses
near at hand are often deluged with spray as if with the downpour of
a hurricane. The lake, already deep at the edge, becomes yet deeper
toward the center, where in some places soundings show over three
hundred feet of water.

"The fishing industry supports a population of several thousands, and
there are several hundred fishing boats in addition to the dozen or
so of little steamers which serve the traffic of the lake. Beyond the
circle of the mountains lie the railroads which transport the
