As both Middleton and Arenberg were firmly convinced that the plain would be thick with Comanche scouts, making their passage by daylight impossible, or at least extremely hazardous, they decided to remain in the woods until nightfall. They rode a couple of miles from the camp, tethered their horses in thick bushes, and, sitting near them, waited placidly. Phil Breakstone, and Arenberg talked in low tones, but Middleton sat silent. Phil noticed presently that "The Cap" was preoccupied. Little lines of thought ran down from his eyes to the corners of his nose. Phil began to wonder again about the nature of Middleton’s mission. Every one of the four was engaged upon some great quest, and none of them knew the secret of any of the others. Nor, in the rush of events, had they been left much time to think about such matters. Now Phil again studied Middleton more closely. There was something in the unaccustomed lines of his face and his thoughtful eye indicating a belief that for him, at least, the object of the quest might be drawing nigh. At least, it seemed so to the boy. He studied, too, Middleton’s clean cut face, and the sharp line of his strong chin. Phil had noticed before that this man was uncommonly neat in his personal appearance. It was a neatness altogether beyond what one usually saw on the plains. His clothing was always clean and in order, he carried a razor, and he shaved every day. Nor did he ever walk with a slovenly, lounging gait. Phil decided that something very uncommon must have sent him with the Santa Fé train, but he would not ask; he had far too much delicacy to pry into the secret of another, who did not pry into his own. Middleton and Arenberg had ample food in their saddlebags and Phil and Breakstone combined with it their stock of deer meat. Nothing disturbed them in the thicket, and at nightfall they mounted and rode out into the plain. "I know something about this country before us," said Breakstone. "It runs on in rolling swells for a march of many days, without any streams except shallow creeks, and without any timber except the fringes of cottonwoods along these creeks." "And I know which way to go in order to overtake the train," said Middleton. "Woodfall said that they would head straight west, and we are certainly good enough plainsmen to keep our noses pointed that way." "We are, we surely are," said Bill Breakstone, "but we must keep a good watch for those Comanche scouts. They hide behind the swells on their ponies, and they blend so well with the dusky earth that you’d never notice ’em until they had passed the signal on to others that you were coming and that it was a good time to form an ambush."
