Although they realized that the man they sent for the wrench had nearly half a mile to go and come by the roundabout way, they asked one another if he was making the wrench! Men began poking their heads into the course and calling, "Need any help down there," and Grant cried, "Yes, go to the pump in the main balcony with your buckets and get water." The man sent for the wrench appeared down the long passage. Grant yelled, "Hurry--hurry, man!" But though he came running, the fire seemed to be going faster than he was. They could hear men calling and felt that there was confusion at the end of the air course where it turned into the main passage ahead of the flames. A second torch exploded, scattering the fire far down the course. The man, breathless and exhausted, ran up with the wrench. Then they felt the air in the air course stop moving. They looked at one another. "Yes," said the man with the wrench, "I told 'em to reverse the fans and when we got the water turned on we'd hold the fire from going to the other end of the passage." He said this between gasps as he tugged at the water plug with the wrench. He hit it a vicious blow and the cap broke. The fan had reversed. The air was rushing back, bringing the flames to the barn. They beat the fire madly with their coats, but in two minutes the roaring air had brought the flames upon them. The loose timber and shavings in the barn were beginning to blaze and the men ran for their lives down the air course. As they ran for the south passage, the smoke followed them and they felt it in their eyes and lungs. The lights behind them were dimmed, and those in front grew dim. They reached the passage in a cloud of smoke, but it was going up the air shaft and did not fill the passage. "Mugs," yelled Grant to a boy driving an ore car, "run down this passage and tell the men there's a fire--where's your father?" "He's up yon way," called the boy, pointing in the opposite direction as he ran. "You tell him." The fire was roaring down the air course behind them, and Grant and the three men knew that in a few minutes the reverse air would be sucking the flames up the air shaft, cutting off the emergency escape for the men on the first and second levels. Grant knew that the emergency escape was not completed for the third level, but he knew that they were using the air chute for a temporary hoist for the men from the third level and that the main shaft was not running to the third level.
