This had at once given Bart his cue for playing a joke, and it might be mentioned that the fun-loving youth never let go by a chance to play a trick. A little later, that same afternoon, after Fenn had been sufficiently “rigged” over his new fad, Bart Keene might have been seen whispering cautiously to Ned and Frank.
His proposal was that the three of them should pay a surreptitious visit to the school that Friday night, and, from the room of Professor Long, the science teacher, take a number of turtles, snakes and small alligators which the instructor kept for the use of his class in biology. The three conspirators planned to remove the reptiles, take them to Fenn’s house, slyly put them in with his collection of turtles, and then see what their chum would say when he found his number of reptiles so unexpectedly increased.
The plan found favor on the part of Ned and Frank. They had met at Bart’s home after supper, and started off, leaving word with Alice, that if Fenn accidentally came, he was to be detained, entertained, or something done to him, to prevent him from becoming suspicious over the absence of the three lads.
But Fenn, or Stumpy, which he was more frequently called, had no suspicions, and did not leave his house that night. Meanwhile, as told in the first chapter, Bart and the others had gone to the school, had suffered a momentary alarm at the sight of the mysterious man, and had finally gained an entrance through the front door, unexpectedly found open.
“Well, we’re in here, what’s next on the program?” asked Ned, of Bart.
“Go ahead up stairs, and don’t make any more noise than you have to.”
Long familiarity with the interior arrangements of the High School enabled the three lads to ascend the stairs without the aid of a light. Bart, as a precaution, however, had brought along a pocket electric flash lamp, to use when they reached the case of live reptiles.
They got to the room where Professor Long gave instruction, and when Bart sent out little flashes of light, all gazed quickly around.
“No traces of any burglar here,” observed Frank.
