"No," replied Harry. "For one thing, it's quite a long way to the nearest mill and we'd have to build a skidway for a mile or two down to the water. Besides, in a general way, it's only the redwood and red cedar that the mills have much use for." Then he gave Frank a handspike that lay close by, and between them they prized up one end of a log so that he could slip a chain sling under it. The other end of the chain was attached to the yoke of the oxen, and when he called them the big white and red beasts hauled the log away until he stopped them and went back for another. Frank did not find much difficulty in this, but it was different when they had drawn six or seven of the logs together and laid them side by side. Harry said that the next lot must go on top of the others, and Frank was wondering how they were to get them there, when his companion laid two or three stout skids some distance apart against the first of the row. These, it was evident, would serve as short, slanting bridges, but Frank was still not clear as to how the next log could be propelled up them. When Harry brought it up he slipped the chain along toward its middle, though it cost the boys an effort to prize the mass up with their handspikes, after which he made one end of the chain fast on the opposite side of the row, around which he led the oxen. The other end he hooked to their yoke, so that it now led doubled across the row and around the trunk they wished to raise. He said that when the chain was pulled the log would roll up it. He next shouted to the oxen, who plodded forward straining at the yoke, while he and Frank slipped their handspikes under opposite ends of the log. "Heave!" he cried. "Send her up!" Frank did his utmost, with the perspiration dripping from him and the veins on his forehead swelling, but the ponderous mass rolled very slowly up the skids, and several times he fancied it would drag the oxen backward and slide down on him. Indeed, for about half a minute it hung stationary, though Harry, who dared not draw out his handspike, shouted frantic encouragement to the straining beasts. Then it moved another inch or two, and one released skid shot up as though fired out of a gun when the log rolled upon the first of the preceding ones. They worked it well across them, and then freeing the chain went back for another, though Frank's arms felt as if they had been almost pulled out of their sockets. "You want somebody to keep the oxen up to it as well as two to heave, when the logs are as big as these," said his companion. "Still, some of the small ranchers do the whole thing alone."
