For many months the survey party has tramped up and down the slopes of the Himalayas. Nothing has happened to interfere with the purposes of this undertaking. The chief is preparing for return to Calcutta.
Oswald and Karl Ludwig have taken a ride of several miles from camp. In the distance Karl sees a solitary horseman. Through his field-glasses he notes that the distant rider is beckoning toward some farther point. Four horsemen, with rifles across their saddles, are now in sight. Oswald has been hidden from view of these by a slope upon which Karl reined his horse. The four when within about a mile veer to the right. It soon becomes evident to Karl that these are trying to get between him and the camp. He tells Oswald his fears, who promptly joins Karl, facing these unknown horsemen. Making a turn near the trail, the four rapidly approach. Both drop their bridle-reins, grasping the repeating, long-range weapons.
[Illustration: "WHEN WITHIN ABOUT A HALF-MILE, THE FOUR RAISED THEIR WEAPONS."]
When within about a half-mile the four raise their guns at once. Karl and Oswald elevate their weapons, and the six discharges seem together. Karl's rifle drops, and he hurriedly loosens his feet from the stirrups, as the horse sinks, shot through the brain. Oswald again shoots, when his horse falls to the ground. The remaining two of the enemy press forward, firing repeatedly. Karl has been disabled by a wound in the right arm, and can render no further help. His gun has rolled down the slope, out of reach.
His horse dead and Karl wounded, Oswald again fires, while shots whiz by his head. Only one of the attacking party is now advancing. Oswald fires his remaining charge, but fails to stop his foe, who takes deliberate aim.
Seeing that his only chance to escape being killed is by feigning death, Oswald drops heavily to the ground. With yell the other spurs forward, followed in the distance by another, who, having lost his horse, now rushes to be in at the death.
Having signaled Karl to make no resistance, Oswald is lying in apparent stupor when the horseman rides up and dismounts. Bending over the prostrate form, his long black hair is grasped by Oswald's left hand, who, springing to his feet and giving that strong right arm a swing, strikes the surprised bandit such hard blow under the left ear that there is no need for another. Picking up the rifle dropped by his quivering foe, Oswald fires the remaining charge after the fleeing form of the other robber.
