Having reached this point in his deductions, Billy smote his hands together. He was trembling with excitement so that he filled his pipe with difficulty. By the time it was drawing well he was back examining his mental picture of the country.
West of Rickett about the same distance as Morgan Hills, ran the Wago Mountains, low, rolling ranges which would hardly form an impediment for a horseman. Across these Barry might cut at a good speed on his western course, but some fifteen or twenty miles from Rickett he was bound to reach a most difficult barrier. It was the Asper river, at this season of the year swollen high and swift with snow-water—a rare feat indeed if a man could swim his horse across such a stream. There were only two places in which it could be forded.
About fifty miles north and a little east of the line from Rickett the Asper spread out into a broad, shallow bed, its streams dispersed for several miles into a number of channels which united again, farther down the course, and made the same strong river. Towards this ford, therefore, it was possible that Dan Barry would head, in the region of Caswell City.
There was, however, another way of crossing the stream. Almost due west of Rickett, a distance of fifteen miles, Tucker Creek joined the Asper. Above the point of junction both the creek and the river were readily fordable, and Barry could cross them and head straight for his goal.
It was true that to make Tucker Creek he would have to double out of the Morgan Hills and brush back perilously close to Rickett, but Billy was convinced that this was the outlaw's plan; for though the Caswell City fords would be his safest route it would take him a day's ride, on an ordinary horse, out of his way. Besides, the sheriff had always said: “Barry will play the chance!”
Billy would have ventured his life that the fugitive would strike straight for the Creek as soon as he doubled out of Morgan Hills.
Doors began to bang; a hundred pairs of boots thudded and jingled towards Billy; the noise of voices rolled through the outer hall, poured through the door, burst upon his ears. He looked up in mild surprise; the first wave of Rickett's men had swept out of the courthouse to take the trail of the fugitive or to watch the pursuit; in this second wave came the remnants, the old men, the women; great-eyed children. In spite of their noise of foot and voice they appeared to be trying to walk stealthily, talk so softly. They leaned about his desk and questioned him with gesticulations, but he only stared. They were all dim as dream people to Billy the clerk, whose mind was far away struggling with his problem.
“Pore old Billy is kind of dazed,” suggested a woman. “Don't bother him, Bud. Look here!”
The tide of noise and faces broke on either side of the desk and swayed off towards the inner office and vaguely Billy felt that they should not be there—the sheriff's privacy—the thought almost drew him back to complete consciousness, but he was borne off from them, again, on a wave of study, pictures. Off there to the east went the fifteen best men of the mountain-desert on the trail of the slender fellow with the black hair and the soft brown eyes. How he had seemed to shrink with aloofness, timidity, when he stood there at the door, giving his name. It was not modesty. Billy knew now; it was something akin to the beasts of prey, who shrink from the eyes of men until they are mad with hunger, and in the slender man Billy remembered the same shrinking, the same hunger. When he struck, no wonder that even the sheriff went down; no wonder if even the fifteen men were baffled on that trail; and therefore, it was sufficiently insane for him, Billy the clerk, to sit in his office and dream with his ineffectual hands of stopping that resistless flight. Yet he pulled himself back to his problem.
Considering his problem in general, the thing was perfectly simple: Barry was sure to head west, and to the west there were only two gates—fording the creek and the river above the junction in the first place, or in the second place cutting across the Asper far north at Caswell City.
