"Which, right there," dryly remarked Ned as he disposed of the last of a generous slice of melon, "is rather indefinite."

When Buck, whose real name they had discovered to be William Bourke—easily corrupted into "Buck"—appeared, the boys had a delicate job before them. Inquiry had quickly shown them that Buck's twenty-five years on the old Santa Fe trail as guide and an active service in the army as scout easily made him the man to conduct Elmer to the north.

To all their long explanations and reasons Buck listened in silence. When there seemed nothing more to be said, Buck smothered the still glowing end of a cigarette between his dark weather-beaten fingers and said slowly:

"When do we start?"

It was arranged that on the second morning Buck should be ready for a journey of uncertain length; that the general direction should be north; that the final destination should be revealed by Elmer on the second morning out.

"Soldier-like," Buck had commented, "and that's the way I like it."

Buck and an assistant were to take an outfit of two wagons, each drawn by four horses. In the lighter wagon six barrels of water were to be carried for use in case the usual "water holes" were dry. In case of an accident, the lighter wagon and horses were to be sent south by the second man and Elmer and Buck were to make a quick dash forward with what water and supplies could be carried on the other wagon.

Old Buck made rather light of the matter.

"Injuns ain't nothin' nowadays," he had explained, shrugging his shoulders, "ye jest want to keep yer bearin's and git used to drinkin' atmosphere and ye'r all right."

The contract with Buck called for thirty dollars a day in money and food for himself and a helper. Both parties to the contract were satisfied and after Buck's fresh cigarette disappeared in the direction of the town the boys lost no time in turning in for a good night's rest.
