concentric tube having perforations opening into the
casing, the inner end of the said tube being closed.
The liquid peat is fed to a preheating jacket around the
cooling and regenerating tube, and passes from this by
an outside pipe to about the outer end of the carbonising
tube, from whence it is led to the annular space between
the inside of the said tube and the outside of the casing
therein. The peat passes along this annular space, through
the bracket and against a spring-controlled valve, capable
of regulation, and adapted to be pushed back by the
pressure of the peat, and then escapes through a suitable
outlet. (Seven claims.)

Coal Merchant Fined £220.—At Old-street Police Court
on Monday, Arthur F. Sarfam, trading as Chandler and
Son, coal merchants, Stepney Green, was fined £220 and
ordered to pay 16 guineas costs for selling coal at a
price in excess of that laid down by the Controller. The
magistrate said that as the defendant had, on his own
admission, 20,000 customers, there must have been con-
siderable profiteering.

Scottish Mineral Oil.—According to Press reports, a
provisional agreement has been effected for the establish-
ment of a central selling agency to dispose of the products
of the Broxburn Oil Company Limited, Oakbank Oil
Company Limited, Pumpherston Oil Company Limited,
James Ross and Company, Philpstoun Oil Works, and
Young’s Paraffin Light and Mineral Oil Company Limited.
A private company may be formed to act as the agent.

Miners' Wages.—There is a further movement on the
part of the coal miners of Great Britain for another appli-
cation for a general advance in wages. The executive of
the Miners’ Federation of Great Britain met at the Grafton
Hotel yesterday (Thursday), and after the meeting Mr.
Smillie informed out Labour correspondent that the
executive had had under consideration resolutions from a
number of districts in favour of a claim for a further
advance in* wages. The executive decide to convene a
special conference of delegates to be held in London on
June 5. The executive passed a resolution of sympathy
with Mr. John Wadsworth, M.P., secretary of the York-
shire Miners’ Association, upon the death of his son, who
has been killed in action.

The coal shortage is becoming acute in Lancashire, and
efforts are being made to obtain supplies from Northum-
berland and Durham.

A meeting of coal exporters wTas held at the Piccadilly
Hotel, London, on Wednesday, to consider the brokerage
question. The result of the meeting has not yet been
announced.

In view of the coal restrictions, the Board of Education
is asking the education authorities to schedule their
requirements, se that the real needs of schools can be met
by arrangement with the Coal Mines Department of the
Board of Trade.
