During the insurrection of 1837-'38 he accompanied his regiment
to the Province of Canada, and on the conclusion of the treaty of
Washington in 1842, he was appointed, on the part of the English
Government, Commissioner for establishing and marking the
north-eastern boundary line between the United States and the
British possessions on this continent, and was not relieved from
that duty until 1847, when the labors of the joint commission
were finally closed. The greater part of the intervening period
was of course spent in Canada and the United States, and General
Estcourt resided, during most of the years 1845 and 1846, at
Washington, where his intelligence and his agreeable social
qualities rendered him a highly acceptable guest in the best circle^
of the American capital. After his return to England he repre-
sented Devizes in Parliament, and was there distinguished for his
characteristic soundness of judgment and his usual conscientious
industry. He was soon promoted to the rank of Colonel, and
was subsequently employed in various important duties, among
which may be mentioned a commission to visit the schools of
mihtary practice on the Continent, and inquire into the expediency
of organizing similar institutions in England, for the instruction
of British soldiers in the use of improved fire-arms.
