In School and Out by Oliver Optic

It would have damaged the self-esteem of the Regulators if they could have seen how little notice was taken of their absence at the Institute on the day following the development of the mutiny. Every thing went on as usual, and the instructors did not even allude to the rebels or the rebellion. It seemed to be the policy of the principal to maintain a "masterly inactivity" in regard to them.

Perhaps Colonel Brockridge was not so indifferent as he appeared to be. He had stationed men on both sides of the lake to prevent any communication between the mutineers and persons on the shore. At noon it was reported that a boy by the name of Leslie, who lived in Tunbrook, and who had been expelled from the Institute, had attempted to visit the island. Richard was curious to know who Leslie was, for he had heard the name mentioned by the Regulators.
