The house was gratefully cool and dark after the summer heat out of doors. The little doctor sat in the darkest room and dissertated cannily on the strange variety of subjects which a Scotchman can always bring up on the most ordinary occasions.

The doctor was not only a learned man, as was evidenced by his position in the School of Mines and his wonderful collections, but was a scout of long standing, a physician of merit, and an Indian authority of acknowledged weight. Withal he was so modest that these things became known only by implication or hearsay, never by direct evidence. Mrs. McPherson was not Scotch at all, but plain comfortable American, redolent of wholesome cleanliness and good temper, and beaming with kindliness and round spectacles. Never was such a doctor; never was such a Mrs. McPherson; never was such a dinner! And they brought in after-dinner coffee in small cups.

"Ah, ha! Mr. de Laney," laughed the doctor, who had been watching him with quizzical eye. "We're pretty bad, but we aren't got quite to savagery yet."

Bennington hastened to disavow.

"That's all right," the doctor reassured him; "that's all right. I didn't wonder at ye in this country, but Mrs. McPherson and mysel' jest take a wee trip occasionally to keep our wits bright. Isn't it so, Mrs. Mac?"

"It is that," said she with a doubtful inner thought as to the propriety of offering cream.

"And as for you," went on the doctor dissertatively, "I suppose ye're getting to be somewhat of a miner yourself. I mind me we did a bit of assay work for your people the other day—the Crazy Horse, wasn't it? A good claim I should judge, from the sample, and so I wrote Davidson."

"When was this?" asked the Easterner, puzzled.

"The last week."

"I didn't know he had had any assaying done."
