"Ditto here," announced Dave.

All of the students had gone to their dormitories, and once more quiet settled over the Hall. The light that had been lit was extinguished, and one after another the boys hopped into bed and tucked the covers in around them.

"Great hambones! What's this!" came, an instant later, from Phil, and he began to wiggle from head to foot.

"Adam's tombstone, but this is fierce!" cried the senator's son and sat bolt upright.

"I should say it was!" declared Dave, as he also thrashed around. "I can't stand this. Who put something in my bed?"

"I didn't!" declared Buster.

"Nor I!" declared one after another of the occupants of the dormitory.

Once more the boys got up, and the light was again lit. It was soon discovered that a mass of burdock burs had been placed in the beds of Phil, Roger, and Dave. None of the other beds had been touched.

"This is an itchy joke and no mistake," said Dave, with a sickly grin.
