MINING AND OTHER NOTES.

The annual report of the Metropolitan Water Board for
the year ended March 31 last, mentions that 192,034 tons of
coal was burnt, an increase of 1,607 tons over the previous
year. There was also a total consumption of oil of
40,243 gals. The amount consumed in the previous year—
for the first time—was only 702 gals. The number of
engines is 281, of a 43,305 total horse power, with 496
boilers.

Messrs. Yeadon, Son and Company, Leeds, have received
an order from a leading coal shipping firm on the Continent
for one of their latest improved briquette plants to produce
Ovoid briquettes, suitable for boiler and domestic use,
at the rate of 50 tons per day to commence with.

The arrangements for the meeting of the British
Association at Manchester in September were reported at a
meeting presided over by the Lord Mayor at the Manchester
Town Hall on the 22nd inst. Prof. Hickson said that the
meeting would be curtailed. The first session would open
on the Tuesday and close on the Saturday. The guarantee
fund has reached a total of 1-3,544. So far the section for
economics is the only one that has its three days’ programme
definitely arranged.

Mr. C. E. Ellis, whose resignation from the boards of
Messrs. John Brown and Company, Messrs. Thomas Firth
and Sons, and the Coventry Ordnance Works, has been
announced on his appointment to the committee being
formed by the Minister of Munitions, has been elected to a
seat on the directorate of the Great Eastern Railway
Company, vacant through the death of Sir Arthur Trcdgold
Lawson, Bart.

Mr. A. S. E. Ackermann, B.Sc. (Engineering),
A.M.I.C.E., the secretary of the Society of Engineers, has
been awarded a silver medal by the Royal Society of Arts
for his paper on “ The Utilisation of Solar Energy.”

The City Corporation and the London Chamber of
Commerce have combined in the formation of a London
Court of Arbitration. Mr. Stanley Machin is the first
chairman. The court is managed by a committee consisting
of equal numbers of representatives of the Corporation and
the Chamber, ten being elected and two appointed by each
body. The object of the court is to provide for the speedy
determination of commercial disputes by arbitration, the
following being the form of arbitration clause recommended
for insertion in contracts :—“ All disputes which may arise
under, out of, or in connection with, or in relation to this
contract shall be submitted to the arbitration of the London
Court of Arbitration, under its rules for the time being.’’
The court is now a reorganised institution in the commercial
organisation of the metropolis, and is the successor of the
“ London Chamber of Arbitration ” formed jointly by the
Corporation and the Chamber of Commerce in 1892 at the
Guildhall. In 1905 it was located at the London Chamber
of Commerce, and has since performed useful work in supple-
menting, but not superseding, the machinery of the Law
Courts, and the arbitration procedure in the grain, coal,
metal, timber and produce markets under clauses in
contracts.
