"I have done the lawn and the bicycle shed," said, he. "I have also had
a rumble through the Ragged Shaw. Now, Watson, there is cocoa ready in
the next room. I must beg you to hurry, for we have a great day before
us."

His eyes shone, and his cheek was flushed with the exhilaration of the
master workman who sees his work lie ready before him. A very different
Holmes, this active, alert man, from the introspective and pallid
dreamer of Baker Street. I felt, as I looked upon that supple, figure,
alive with nervous energy, that it was indeed a strenuous day that
awaited us.

And yet it opened in the blackest disappointment. With high hopes we
struck across the peaty, russet moor, intersected with a thousand sheep
paths, until we came to the broad, light-green belt which marked the
morass between us and Holdernesse. Certainly, if the lad had gone
homeward, he must have passed this, and he could not pass it without
leaving his traces. But no sign of him or the German could be seen. With
a darkening face my friend strode along the margin, eagerly observant
of every muddy stain upon the mossy surface. Sheep-marks there were
in profusion, and at one place, some miles down, cows had left their
tracks. Nothing more.

"Check number one," said Holmes, looking gloomily over the rolling
expanse of the moor. "There is another morass down yonder, and a narrow
neck between. Halloa! halloa! halloa! what have we here?"

We had come on a small black ribbon of pathway. In the middle of it,
clearly marked on the sodden soil, was the track of a bicycle.

"Hurrah!" I cried. "We have it."

But Holmes was shaking his head, and his face was puzzled and expectant
rather than joyous.

"A bicycle, certainly, but not THE bicycle," said he. "I am familiar
with forty-two different impressions left by tires. This, as you
perceive, is a Dunlop, with a patch upon the outer cover. Heidegger's
tires were Palmer's, leaving longitudinal stripes. Aveling, the
mathematical master, was sure upon the point. Therefore, it is not
Heidegger's track."

"The boy's, then?"

"Possibly, if we could prove a bicycle to have been in his possession.
But this we have utterly failed to do. This track, as you perceive, was
made by a rider who was going from the direction of the school."

"Or towards it?"

"No, no, my dear Watson. The more deeply sunk impression is, of course,
the hind wheel, upon which the weight rests. You perceive several pla
