They were about, one afternoon, to take a ride, when a small party of mounted Indians—who, as they had several pack horses, were evidently coming to trade—were seen approaching the fort.

“We must wait to receive these fellows,” said Captain Mackintosh, “and I am afraid, my girls, there will be little chance for you afterwards to get your gallop.”

“Oh, papa, Norman can come with us, if you can spare him; it would be a pity to lose this lovely day,” said Effie.

Sybil said nothing, and Captain Mackintosh, perhaps against his better judgment, consented to let the girls go, supposing that the new comers would be too fully engaged in trading to notice them. They accordingly mounted, and accompanied by Norman and two of the men who usually acted as their body guard, set out a short time before the Indians arrived at the camp.

No one in the fort observed that one of the savages turned round his horse and galloped off in the direction from whence they had come.

As there were not more than a dozen men, and as they, according to custom, had deposited their arms outside the fort, they were admitted without hesitation.

Captain Mackintosh, well acquainted with the various Indian nations, was struck by the appearance of their features, which were those of the Blackfeet, although they wore none of the distinctive ornaments of that tribe, and introduced themselves as Peagons, whose territory lies to the southward. Their chief, a plausibly mannered man, stated that they had been induced to come to Fort Duncan by hearing that better value was given for peltries there than was to be obtained from the Long Knives. They seemed, however, in no hurry to begin business, and begged that food might be provided for the party, as they had gone several days without shooting a buffalo, hinting that some fire-water would be a welcome addition, though they did not appear surprised when Captain Mackintosh refused to supply the pernicious beverage.

The visitors did ample justice to the feast placed before them, and would apparently have continued eating as long as any meat remained, had not Captain Mackintosh suggested that darkness would come on before they had time to commence trading.

At length, therefore, one of the packs was undone, and business proceeded in the usual way.

They were thus engaged, when a little hump-backed Indian, whom nobody had observed, crept in at the gate of the fort, and making his way up to where Captain Mackintosh was superintending affairs, drew a piece of paper from a leathern pouch and put it into his hand.
