he money next evening, and has not
sent it yet which is the reason that I mention this.

"Yours, &c.,

"GRANT."

This letter was directed on the outside to the "Hon. Gideon Barstow,
Salem," and put into the post-office on Sunday evening, May 16, 1830.

"_Lynn, May 12, 1830._

"Mr. White will send the $5,000, or a part of it, before to-morrow
night, or suffer the painful consequences.

"N. CLAXTON, 4TH."

This letter was addressed to the "Hon. Stephen White, Salem, Mass.," and
was also put into the post-office in Salem on Sunday evening.

When Knapp delivered these letters to his friend, he said his father had
received an anonymous letter, and "What I want you for is to put these
in the post-office in order to nip this silly affair in the bud."

The Hon. Stephen White, mentioned in these letters, was a nephew of

When the Committee of Vigilance read and considered the letter,

Conscious that the circumstances justified the belief that he had had a

innocence, that he could unfold the whole mystery. He then disclosed
that he had been an associate of R. Crowninshield, Jr. and George
Crowninshield; had spent part of the winter at Danvers and Salem, under
the name of Carr; part of the time he had been their inmate, concealed
in their father's house in Danvers; that on the 2d of April he saw from
the windows of the house Frank Knapp and a young man named Allen ride up
to the house; that George walked away with Frank, and Richard with
Allen; that on their ret
