on the broad earth which is held in such universal
abhorrence as a snake, the sight of which sends a shiver of disgust and
dread over nearly every one that looks upon it.

When Sam sat down on the fallen tree, he was probably almost near enough
for the coiled _crotalus_ to bury its fangs in him. It reared its head,
and, without uttering its customary warning, most likely measured the
intervening space with the purpose of striking.

The instinct of Bowser at this juncture told him of the peril of his
master, and he began his demonstrations, intended to draw him away from
the spot. At the same time, his barking, and trotting back and forth,
diverted the attention of the rattlesnake to the hound, and thereby
prevented him striking the unsuspicious boy.

It must have been, also, that during these few minutes the serpent
vibrated his tail more than once, for the nature of the reptile leads
him to do so; but the sound could not have been very loud, as it failed
to attract the attention of Sam until he rose from the log and turned
partly about.

The boy moved around the head of the fallen tree, so as to place
himself on the same side with the rattlesnake, and then he spent a
minute or two in contemplating him at that safe distance.

He was a large one, with sixteen rattles and a button. He lay coiled in
several perfect rings, with his tail softly vibrating and his head
thrown back, as if he expected his enemy to come nigh enough for him to
bury his curved needle-like fangs in some portion of his body, injecting
his poison, so deadly that nothing could have saved the boy from dying
within a few minutes.

The first natural feeling which comes over one when he sees a crawling
snake is to kill it, and Sam Harper did not wait long before yielding to
his inclination.

Standing less than a rod distant, he brought his gun to his shoulder,
and sighted at the head of the venomous reptile, which was held almost
stationary, while the crimson tongue darted in and out as if it were a
tiny spray of blood.

The aim was true, and the head was shattered as though the cartridge
had exploded within it. The body made a few furious writhings and
struggles, and then became still.

Sam viewed the ruin he had wrought for a minute or so, and then,
appreciating the service his dog had wrought him, he turned and patted
the animal.

"You're a fine dog, Bowser, and I forgive you for being good for
nothing."
