It would be hard to get, and it could not be rehearsed before the camera was turned on it.

Luck decided that it should be shot from three angles, at least, and if he could manage it he would have a "panoram" of the whole thing from a height.
The porter came apologetically with his big whisk broom and told Luck that they would all presently be gazing at Dry Lake, or words which carried that meaning.

So Luck permitted himself to be whisked from a half dollar while his thoughts were "in the field" with his camera men and company, shooting a real stampede from various angles and trying to manage so that the dust should not obscure the scene.

After a rain--of course! Just after a soaking rain, he thought, while he gathered up his time-table and a magazine that held his precious figures, and followed the porter out to the vestibule while the train slowed.
It was in this mood that Luck descended to the Dry Lake depot platform and looked about him.

He had no high expectation of finding here what he sought.
