He passed in the track of Joseph toward the rear of the patio. Presently the big man halted, removed his hat, and faced a door beneath the arcade. It was only a momentary interruption. He went on again at once, replacing his hat, but the thrill of apprehension was still tingling in the blood of the gambler. Now they went under the arcade, through an open door, and issued in the rear of the house, Connor's imaginary "monster" dissolved. For they stood in front of a blacksmith shop, the side toward them being entirely open so that Connor could see the whole of the interior. Two sooty lanterns hung from the rafters, the light tangling among wreaths of smoke above and showing below a man whose back was turned toward them as he worked a great snoring bellows with one hand. That bellows was the source of the mysterious breathing. Connor chuckled; all mysteries dissolved as this had done the moment one confronted them. He left off chuckling to admire the ease with which the blacksmith handled the bellows. A massive angle of iron was buried in the forge, the white flames spurting around it as the bellows blew, casting the smith into high relief at every pulse of the fire. Sometimes it ran on the great muscles of the arm that kept the bellows in play; sometimes it ran a dazzling outline around his entire body, showing the leather apron and the black hair which flooded down about his shoulders. "Who--" began Connor. "Hush," cautioned Joseph in a whisper. "David speaks when he chooses--not sooner." Here the smith laid hold on the iron with long pincers, and, raising it from the coals, at once the shop burst with white light as David placed the iron on the anvil and caught up a short-handled sledge. He whirled it and brought it down with a clangor. The sparks spurted into the night, dropping to the ground and turning red at the very feet of Connor. Slowly David turned the iron, the steady shower of blows bending it, changing it, molding it under the eye of the gambler. This was that clangor which had floated through the clear mountain air to him when he first gazed down on the valley; this was the bell-like murmur which had washed down to him through the gates of the valley. At least it was easy to understand why the servants feared him. A full fourteen pounds was in the head of that sledge, Connor guessed, yet David whirled it with a light and deft precision. Only the shuddering of the anvil told the weight of those blows. Meantime, with every leap of the spark-showers the gambler studied the face of the master. They were features of strength rather than beauty from the frowning forehead to the craggy jaw. A sort of fierce happiness lived in that face now, the thought of the craftsman and the joy of the laborer in his strength.
