Partnerships Dissolved.—The London Gazette announces
dissolution of the partnership of J. Harrison, R. Firth, and
S. Rush,forth, trading as the Sunny Bank Colliery Company,
Birkenshaw, Yorkshire; also of G. Buxton (who continues
the business) and F. Wainwright, trading as Wainwright
and Buxton, engineers, 17, Steelhouse-lane, Birmingham.

Hull Coal Trade. — The coal imported into Hull from
British collieries during January totalled 263,557 tons, which
is below the quantity (274,022 tons) in the corresponding
month last year. Of the quantity specified, 19,158 tons wer
brought by river. Export shipments (coastwise) aggregated
21,897 tons.

Coal Difficulty in Germany.—A great scarcity of coal for
all civil purposes is reported in the German Press. As
regards Munich, it was announced that there is no prospect
of obtaining any fresh snnnlies of coal while the cold weather
lasts, and the military authorities issued a series, of cur:
instructions to the municipal authorities—the instructions to
remain in force until further orders. Not only all schools,
but all museums, theatres, cinema theatres, concert rooms,
and public halls are to be closed. This involves the entire
suspension of all public meetings. Ail restaurants, cafes,
and clubs are limited to the use of a single room each, and
are to close at 10 p.m. All fuel belonging to theatres and
other public establishments is confiscated by the. municipality,
and restaurants and hotels require a licence for all fresh
purchases of fuel. Reports in the Frankfurter Zeitung show
that the situation is very serious at Frankfurt and in other
parts of South. Germany.
