There were many speculations concerning what had started the explosions. It was proved that the first had occurred in one of the cars which was standing loaded on the railroad track, while the second explosion had come less than a minute later from what was known as Storehouse No. 3. Then had followed an explosion at Storehouse No. 2, and after that the explosions had come so rapidly and there had been so much excitement that no one could tell exactly what had happened next. But fortunately the explosions had been confined to the storehouses and the loaded cars on the track. The main building of the shell-loading plant had suffered considerably, but a portion was still standing, and some underground vaults, filled with high explosives, had not been reached. Had these explosives gone up, it is more than likely Haven Point, as well as Clearwater Hall and possibly Colby Hall, would have been shaken to their foundations and with great loss of life.
A rigid investigation had been started by three different parties--the owners of the plant, the local authorities, and the Secret Service of the national government. The Secret Service men, of course, made no public report, but the others in authority came to the conclusion that the explosions had been started either by some spies working for the shell-loading plant or by two suspicious-looking men who had been seen several times around the place--the same fellows described by Jed Kessler.
"Maybe those two fellows on the outside had confederates on the inside," remarked Jack, in talking the affair over with his cousins.
"More than likely that's the truth of it," said Randy. "Those fellows often work in gangs."
During the days following the victory over Hixley High, a number of the cadets had gone down to Haven Point at various times, and several brought back the report that they had met Slugger Brown and Nappy Martell driving through the town in their runabout. Slugger and Nappy had put on a lordly air, bowing very condescendingly to those they knew, but refusing to stop for any conversation.
"Those fellows make me weary in the bones," was the way Dan Soppinger expressed himself. "What ever brought 'em to Haven Point? If I had been fired out of the school the way they were, I wouldn't want to show my face around here again."
