The affair was simple enough. Long booms arranged in the form of an open V guided the drive to the sluice gate, through which a smooth apron of water rushed to turmoil in an eddying pool below. Two men tramped steadily backwards and forwards on the booms, urging the logs forward by means of long pike poles to where the suction could seize them. Below the dam, the push of the sluice water forced them several miles down stream, where the rest of Bryan Moloney's crew took them in charge.
Thus through the wide gate nearly three-quarters of a million feet an hour could be run—a quantity more than sufficient to keep pace with the exertions of the rear. The matter was, of course, more or less delayed by the necessity of breaking out such rollways as they encountered from time to time on the banks. At length, however, the last of the logs drifted into the wide dam pool. The rear had arrived at Dam Two, and Thorpe congratulated himself that one stage of his journey had been completed. Billy Camp began to worry about shooting the wanigan through the sluice-way.
Chapter XLVIII
The rear had been tenting at the dam for two days, and was about ready to break camp, when Jimmy Powers swung across the trail to tell them of the big jam.
Ten miles along the river bed, the stream dropped over a little half-falls into a narrow, rocky gorge. It was always an anxious spot for the river drivers. In fact, the plunging of the logs head-on over the fall had so gouged out the soft rock below, that an eddy of great power had formed in the basin. Shearer and Thorpe had often discussed the advisability of constructing an artificial apron of logs to receive the impact. Here, in spite of all efforts, the jam had formed, first a little center of a few logs in the middle of the stream, dividing the current, and shunting the logs to right and left; then “wings” growing out from either bank, built up from logs shunted too violently; finally a complete stoppage of the channel, and the consequent rapid piling up as the pressure of the drive increased. Now the bed was completely filled, far above the level of the falls, by a tangle that defied the jam crew's best efforts.
The rear at once took the trail down the river. Thorpe and Shearer and Scotty Parsons looked over the ground.
“She may 'pull,' if she gets a good start,” decided Tim.
Without delay the entire crew was set to work. Nearly a hundred men can pick a great many logs in the course of a day. Several times the jam started, but always “plugged” before the motion had become irresistible. This was mainly because the rocky walls narrowed at a slight bend to the west, so that the drive was throttled, as it were. It was hoped that perhaps the middle of the jam might burst through here, leaving the wings stranded. The hope was groundless.
“We'll have to shoot,” Shearer reluctantly decided.
