lusion was that they would make good citizens." About eighteen
months after they arrived in Canada the Doukhobors sent the Society of
Friends a collective letter in which they sincerely thanked the English
and American Friends for all the generous help of every kind they had
received at their hands, but begged the Quakers to cease sending them
any more pecuniary support, as they were now able to stand on their own
feet, and therefore felt it right that any further help should be
directed to others who were more in need of it. At Yorktown in the
summer of 1907 the Doukhobors established one of the largest and best
brick-making plants in Canada, a significant testimony to the way in
which the leaders of the community were working in the interests of the
whole. Now and again small bodies broke off from the main community and
adopted a semi-nomadic life, but these formed a very small percentage of
the total number, which in 1908 was over 8000.

DOULLENS, a town of northern France, capital of an arrondissement in the
department of Somme, on the Authie, 27 m. N. of Amiens by rail. Pop.
(1906) 4495. It has a citadel of the 15th and 16th centuries which has
often served as a state prison and is now used as a reformatory for
girls. There are also a belfry of the 17th century and two old churches.
The town is the seat of a sub-prefect and has a tribunal of first
instance; it has trade in phosphates, of which there are workings in the
vicinity, and carries on cotton-spinning and the manufacture of leather,
paper and sugar. Doullens, the ancient _Dulincum_, was seat of a
viscountship and an important stronghold in the middle ages. In 1475 it
was burnt by Louis XI. for openly siding with the house of Burgundy. In
1595 it was besieged and occupied by the Spaniards, but was restored to
France by the treaty of Vervins (1598).

DOULTON, SIR HENRY (1820-1897), English inventor and manufacturer of
pottery, born in Vauxhall on the 25th of July 1820, was from the age of
fifteen actively employed in the pottery works of his father, John
Doulton, at Lambeth. One of the first results of his many experiments
was the production of good enamel glazes. In 1846 he initiated in
Lambeth the pipe works, in which he superintended the manufacture of the
