We reached the pass safely, and on the way down the other side we passed Mr. Oliver, the moving-picture man, with his outfit on a horse. He touched his hat politely and moved out on a ledge to let us by.

"Mind if I take you as you go down the mountain?" he called. "It's a bully place for a picture." He stared at Aggie, who was muffled in a cape and had the dish towel round her head. "I'd particularly like to get your Arab," he said. "The Far East and the Far West, you know."

Aggie gave him a furious glance. "Arab nothing!" she snapped. "If you can't tell a Christian lady from a heathen, on account of her having lost her hat, then you belong in the dirty work you're doing."

"Aggie, be quiet!" Tish said in an awful voice.

But wrath had made Aggie reckless. "'Dirty work' was what I said," she repeated, staring at the young man.

"I beg your pardon. I'm sure I—"

"Don't think," Aggie went on, to Tish's fury, "that we don't know a few things. We do."

"I see," he said slowly. "All right. Although I'd like to know—"

"Good-morning," said Aggie, and kicked her horse to go on.

I shall never forget Tish's face. Round the next bend she got off her horse and confronted Aggie.
