“That leaves us one theory,” decided Rhodes, a little later, as they talked it over in the boys’ room. “Either the man got back before supper or one of the cooks or the janitor went in there. The question is: who, besides the colonel, has a key to Clanhammer Hall?”

6. Rapid Developments

For the next few days nothing worthy of note happened. It was early one morning the following week that things began to move. The boys had studied until bedtime and had turned in when the lights were put out. Life at the school flowed on as it did when the colonel had been there. Mr. Vench seemed busier than usual and made several trips to town. Clanhammer Hall revealed nothing new.

How long the boys had been asleep on that particular night they did not know, but they were aroused by a sound that was entirely new to them. A furious clanging of gongs sounded throughout the school on every hall and stairs, and the cadets started up in bed with rapidly beating hearts. They had often seen the huge gongs out in the halls but had never heard them in action. Now they were being rung violently.

Terry was the first to bounce out of his bed. “Come on, you guys,” he called. “The school is on fire!”

Don and Jim lost no time in springing from their beds and reaching for their clothes. “Too bad they don’t turn on the lights,” he grumbled.

As though in answer to his complaint the overhead lights were turned on and the boys could see what they were doing. The sound of the gongs then died down abruptly, but a rushing, scattering sound told them that the cadets were all up and hurrying into their clothes.

“Wonder where it is?” speculated Jim, as he pulled on his shirt. “I don’t see any blaze or smell any smoke.”

“It may only be a very small one,” said Terry, who was now fully dressed. “I suppose we report in assembly, don’t we? Or maybe we march out on the campus. One thing they have neglected to do around here is to give us any fire regulations.”

Terry was right in his statement and the Mercers wondered if the oversight was due to the fact that the colonel was missing. They opened their door and hurried out into the hall. Almost every door was open and cadets were talking and walking toward the stairs.
