I used a Verascope, a small stereoscopic French machine whose "click" is almost noiseless.

The elephants advanced and we huddled together with rifles ready in the patch of bushes.

It seemed a certainty that they would charge, and that if our bullets could not turn them we would be completely annihilated.

But as yet there was no sign that they saw us, or, if they did, they could not distinguish our motionless forms from the foliage of the scrub.
At last, the foremost elephant, barely thirty feet from us, came to the trail in the grass by which we had retreated when we first saw them.

The trunk, sweeping ahead of it as if feeling for the scent of danger, paused an instant as it reached the trail and then the animal drew back sharply as though stung.
