lifted. Half a dozen wild birds were thrust into the opening. The cover closed again. Lockley listened closely. It was latched from the outside. There would naturally be a fastening on the cover of a compost pit to keep bears from getting at the garbage it was built to contain. The heat grew savage. Thirst was a problem. Once and only once they heard a noise from the world beyond their prison. It was a droning hum which, even through a metal wall, could be nothing but the sound of a helicopter. It droned and droned, very gradually becoming louder. Then, abruptly, it cut off. That was all. And that was all that the four in the metal tank knew about events outside of their own experience. But much was happening outside. Troop-carrying trucks had reached the edge of Boulder Lake National Park, a very few hours after the workmen from the camp had gotten out of it. They had a story to tell, and if it lacked detail it did not lack imagination. The three missing men had their fate described in various versions, all of which were dramatic and terrifying. The two men who had been paralyzed by some unknown agency described their sensations after their release. Their stories were immediately relayed to all the news media. It now appeared that dozens of men had seen the thing descend from the sky. They had not compared notes, however, and their descriptions varied from a black pear-shaped globe which had hovered for minutes before descending behind the mountains into the lake, to detailed word pictures of a silvery, torpedo[46]-shaped vessel of space with portholes and flaming rockets and an unknown flag displayed from a flagstaff. [46] Of course, none of those accounts could be right. The velocity of the falling object, as reported from two radar installations, checked against a seismograph record of the time of the impact in the lake and allowed no leeway of time for it to hover in mid-air to be admired. But there were enough detailed and first-hand accounts of alarming events to make a second statement by the Defense Department necessary. It was an over-correction of the first soothing one. It was intended to be more soothing still. It said blandly that a bolide—a slow-moving, large meteoric object—had been observed by radar to be descending to earth. It had been tracked throughout its descent. It had landed in Boulder Lake. Air photos taken since its landing showed that an enormous disturbance of the water of the lake had taken place. It had seemed wise to remove workmen
