Polish Coalfields Annexed.—According to the Kreuz
Zeitung, the Prussian annexations in Poland will include
about one-quarter of the Polish coalfields. The regions in
which the frontier will be “ rectified ” are the northern
section of the province of Suvalki, the sector between
Thorn and Alexandrovo, and especially the mining district
of Dombrovo. The Prussian territory will include St.
Barbara Hill, which commands the Upper Silesian basin.

Wigan and Districts Miners’ Permanent Relief Society.
—The annual report of the Wigan and Districts Miners’
Permanent Relief Society records another large increase
of members. The membership on December 31, 1917, was
8,987, an increase of 645 members on the year. The total
income was £11,209, an increase of £1,511, the increase of
members and the increase of interest on loans accounting
for the difference. The total expenditure was £7,952, an
increase of £583. An increase of accident pay and death
claims accounts for over £478 of the difference. The
balance on the year’s working, the report states, is excel-
lent, being £3,256, compared with £2,328,- an increase
of £928 over the 1916 balance. The accumulated funds
on December 31, 1917, were £15,736, showing an increase
of £8,623, compared with December 31, 1912. There were
21 fatal accidents, compared with 13 in the previous year,
nine of the fatal cases being single and 12 married,
leaving 12 widows and 17 children on the funds. The
payments to widows were £816, an increase of £21, and
to children, £747, a decrease of £21. The number of cases
chargeable to the society during the year was 2,418, an
increase of 268 compared with 1916. The cost of accident
cases was £4,784, an increase of £385 over the previous
year. The increase in the funds of the society has, the
report adds, been remarkable during the last five years,
there being an adverse balance on the working of the
society in 1912, while in 1913 the balance in favour of the
society was £689; in 1914, £1,278; in 1915, £1,074; in
1916, £2,328, and in 1917, £3,256, a total increase of
£8,635 in the period.
