"Have you got to dismantle that condenser to move it?" asked Dick. "Pretty thoroughly, I'm afraid. But if the Indians are any good at all--" "If Rabbit Tail brings his pet gang," said Dick "there'll be four first class machinists in it, trained at Carlisle. Fellows who work only when they please, but Lord, they are wonders. I saw them put up an oil engine once that had been badly smashed en route. It was a poem, I tell you." "Heaven send them then!" exclaimed Roger. "If they put this thing over for us, I'll pay for it in cold cash as soon as I get it." "Rabbit Tail won't take money for this deal," said Charley. "The others will, but they won't ask for it." Dick filled his pipe, and pushed his coffee cup away with a little smile for Elsa. "My debts are getting so large now," mused Roger, "that I can begin to take a sort of pride in them. Gustav, as Dick's home now, will you come down to the Plant in the morning?" And at Gustav's nod Roger made his adieux and went home to bed. Monday dawned with the usual promise of merciless heat. It seemed as if the torrid days of late summer were harder to bear than July had been. Though there was an occasional dust storm, the air was quiet except for the little gusts of burning wind. These gusts were too transitory to carry a sand storm. But all day long, tall spirals of sand, like water spouts, whirled across the desert. One struck Dick's corral, during his absence, ripped off the roof of the tool house and overturned the watering trough. Several days later, one brought up against the condenser and after knocking off the thatch, collapsed, deluging the apparatus with sand. There was something uncanny about these gigantic figures, whirling suddenly across the desert, now viciously ripping up a cholla or a Joshua tree, now collapsing ridiculously against a rock. It was now too, that thunderstorms were occasionally heard in the distant western ranges, though rain seemed forever denied to the desert valleys. But on the Sunday noon before Rabbit Tail's gang was to arrive, the impossible happened. Roger and Gustav were eating their monotonous lunch of corned beef and canned brown bread when a curious roar broke the desert silence. As the two men looked at each other questioningly, there was a deafening crash and a huge deluge of water smashed down on the cook tent. The sun-baked canvas was like a sieve and in a moment both men were saturated. "A cloud burst!" exclaimed Roger, grinning fatuously at the delicious sensation of wet clothing and skin. "Gott, vat a country!" cried Gustav. Roger's grin disappeared. "The living tent, by Jove!" Heedless of the blinding torrent, he dashed to the tent where all the morning he had been sorting and checking drawings and notes. He stopped in the doorway appalled. Everything in the tent was dripping. Drawings, instruments, camera, open trunks and bedding were flooded. The patient work of months must be done over.
