of base, leading the vear-guard in the movement from Turkey creek to Harrison's landing. He was promoted major-general of volunteers, 4 July, 1862, and till September was in Yorktown, where he put the works in conditidn for defence. On 22 Sept., 1862, he was assigned to the command of all the National troops in Virginia south of James river, where he rendered important service by his brilliant defence of Suffolk against a superior force under Longstreet, whose position on Hill's point he stormed and captured on 4 May, 1863, thus virtually ending the siege. After an absence of several months, which was necessitated by injuries that he had received at Suffolk, he held command in North Carolina till April. 1864, and, after an- other leave of absence, on the Canada frontier till the close of the war. He was mustered out of service, 24 Aug., 1865, and in 1866 organized at Syracuse the New York state life insurance com- pany, of which he was president till his death.
PECK, John Mason, clergvman, b. in Litchfield, Conn.. 31 Oct., 1789 ; d. in Rock Spring, St.
Clair CO., 111., 15 March, 1858. He was the son of
a farmer in humble circumstances, and, after being
educated at the common schools, removed in 1811
to Greene county, N. Y.. where he united with the
Baptist church. The same year he was licensed to
preach, and began his pastoral work at Catskill,
while prosecuting his studies and supporting him-
self by teaching. He was ordained in Catskill, 9
June, 1813, and the following year became pastor
of the church at Amenia, N. Y. He was then sent
to the west by the Baptist general convention as a
missionary, and reached St. Louis at the end of
1817. During the next nine years he was engaged
as an itinerant preacher and a teacher, travelling
in the former capacity through Missouri and Illi-
nois, and finally fixing his residence at Rock Spring,
in the latter state. In 1836 he raised money and
aided in organizing the Rock Spring seminary for
educating common-school teachers and ministers.
In April, 1829, he began the publication of " The
Pioneer," the first organ of the Baptist church in
the western states. In 1831 he spent three months
in planning with Rev. Jonathan Going the Ameri-
can Baptist home missionary society, and the same
year he issued "A Guide for Emigrants" (Bos-
ton), a small but useful publication. He soon
afterward began a monthly periodical entitled " The
Illinois Sunday-School Banner." In 1834 appeared
his "Gazetteer of Illinois" (Jacksonville, 1834;
Philadelphia. 1837). In 1835 Shurtleff college was
founded at Upper Alton, 111., to take the place of
his Rock Spring seminary. To endow this institu-
tion Dr. Peck travelled nearly 6,000 miles, and col-
lected $20,000. In watching over and helping the
new enterprise, and in aiding in the establishment
of a theological institution at Covington, Ky., he
was occupied until 1843. which year, with the two
following, he spent in Philadelphia as correspond-
ing secretary and financial agent of the American
Baptist publication society. Returning to the west,
he was pastor of several important churches in
Missouri, Illinois, and Kentucky. In 1852 he re-
ceived the degree of D. D. from Harvard. Dr.
Peck was a master spirit among the pioneers.
" Perhaps no man of the class." says an intimate
friend, " did more than he to guide the thoughts,
mould the manners, and form the institutions of
the west. He was an embodiment of western char-
acter, plain, frank, self-reliant, fearless, indomi-
table." He was an important contributor to nearly
all the historical societies of the northwestern
states and territories, and piiblished, besides the
works already mentioned, '• New Guide for Emi-
grants to the West " (Boston. 1836) and •' Father
Clark, or the Pioneer Preacher " (New York, 1855).
He is also the author of a Life of Daniel Boone "
in Sparks's " American Biography," and edited the
2d edition of " Annals of the West " (Cincinnati).
His large and valuable collection of newspapers
and pamphlets was destroyed by fire a few years
before his death, but he left his large collection of
manuscripts to the Rev. Rufus Babcock. who pub-
lished " Forty Years of Pioneer Life : Memoir of
John Mason Peck, edited from his Journals and
Correspondence " (Philadelphia, 1864).
