There was no time to inquire to what this exclamation, which was delivered in a very rapturous tone, referred; for he had already thrown open the door of the room; into which Nicholas, followed by Smike with the bundle on his shoulder (he carried it about with him as vigilantly as if it had been a sack of gold), straightway repaired.
Affairs now appearing to assume a more serious complexion, the watch was renewed with increased vigilance; an officer was procured, who took up his abode in the same tavern with Squeers: and by him and Frank Cheeryble the footsteps of the unconscious schoolmaster were dogged, until he was safely housed in the lodging at Lambeth.
There are no more uses of "vigilant" in the book.
