He and two of the new mountain men had been for two days cutting up some dead and down trees that encumbered the enclosure at headquarters. They cross-cut the trunks into handy lengths; bored holes in them with a two-inch augur; loaded the holes with blasting powder and a fuse, and touched them off. The powder split the logs into rough posts small enough to handle. These fragments they carried laboriously to the middle of the meadow, where they stacked them rack-fashion and on end. The idea was to combine business with pleasure by having a grand bonfire the night of the Fourth of July. For this day other preparations were forward. Amy promised a spread for everybody, if she could get a little help at the last moment. As many of the outlying rangers as could manage it would come in for the occasion. A shooting match, roping and chopping contests, and other sports were in contemplation. As the time drew near, various mysteries were plainly afoot. Men claimed their turns in riding down the mountain for the mail. They took with them pack horses. These they unpacked secretly and apart. Amy gave Bob to understand that this holiday, when the ranks were fullest and conditions ripe, went far as a substitute for Christmas among these men. Then at noon of July second Charley Morton dashed down the trail from the Upper Meadow, rode rapidly to Headquarters, flung himself from his horse, and dove into the office. After a moment he reappeared, followed by Thorne. "Saddle up, boys," said the latter. "Fire over beyond Baldy. Ride and gather in the men who are about here," he told Bob. Bob sprang on Charley Morton's horse and rode about instructing the workers to gather. When he returned, Thorne gave his instructions. "We're short-handed," he stated, "and it'll be hard to get help just at this time. Charley, you take Ware, Elliott and Carroll and see what it looks like. Start a fire line, and do the best you can. Orde, you and Pollock can get up some pack horses and follow later with grub, blankets, and so forth. I'll ride down the mountain to see what I can do about help. It may be I can catch somebody by phone at the Power House who can let the boys know at the north end. You say it's a big fire?" "I see quite a lot of smoke," said Charley. "Then the boys over Jackass way and by the Crossing ought to see it for themselves." The four men designated caught up their horses, saddled them, and mounted. Thorne handed them each a broad hoe, a rake and an axe. They rode off up the trail. Thorne mounted on his own horse. "Pack up and follow as fast as you can," he told the two who still remained. "What you want we should take?" asked Jack. "Amy will tell you. Get started early as you can. You'll have to follow their tracks."
