REPORTS AND DIVIDENDS.

Brunner, Mond and Company Limited.—The report for
the year ended March 31 shows a balance to the credit of
profit and loss account of £1,117,153, which, with the
amount of £121,547 brought forward, makes a total of
£1,238,700. The directors, after paying preference divi-
dends, propose to deal with the balance as follows: An
interim dividend on the ordinary at 25 per cent, per annum
(paid on December 15), and a further dividend on the ordi-
nary capital at 30 per cent, per annum, subject to deduc-
tion of income tax, to place to suspense account £100,000,
to write off patents accounts £2,500, and carry forward,
including provision for excess profits tax, £216,228.

Clydesdale (Transvaal) Collieries Limited.—A cable from
the head office states the directors have declared a dividend
of 5 per cent. (Is. per share), payable to all shareholders
registered 30th inst.

Evans (Richard) and Company Limited.—The ordinary
share dividend for the past year is now made up to 10 per
cent., tax free, with £7,708 forward. The preceding year’s
dividend was the same.

Head, Wrightson and Company Limited.—The directors
announce that the 27th annual meeting of shareholders will
be held at the registered offices, Thornaby-on-Tees,
to-morrow (Saturday), June 30, at 11 a.m. The directors,
in addition to the interim dividend of 5 per cent, paid
December 31, 1916, propose to pay 5 per cent., less income
tax, and a bonus of 2s. 6d. on each £5 ordinary share,
making the total payment the same as the previous year.

Kent Collieries Limited.—The report states that opera-
tions at the colliery have been suspended since December
1915, but the directors are advised that the plant and
machinery has been adequately protected. Some of the
boilers and rolling stock have recently been requisitioned
by and sold to H.M. Office of Works. Tests are still
being carried out by the Channel Collieries Trust Limited
for the purpose of ascertaining the most advantageous
method of using the Dover ore for steel making purposes.
The directors have conferred on several occasions with the
committee of shareholders appointed at the last annual
general meeting, and joint conferences have been held
with the directors of the Channel Collieries Trust Limited,
in the hope of formulating an acceptable scheme for the
fusion of the interests of the trust and of Kent Collieries
Limited in a new company to be formed to carry on the
amalgamated undertakings. On March 19, in accordance
with the terms of an agreement between the company and
the trust, the latter offered for sale to the debenture
holders and shareholders of the company the 7 per cent,
notes of this company for £315,000 at 90 per cent, of their
nominal amount. In connection with this offer, the share-
holders and debenture holders were supplied with an out-
line of the scheme of fusion then under consideration.
Since that date, subject to the approval of the shareholders
and debenture holders, the scheme has been finally agreed
on. The directors are advised by the chairman of the
Channel Collieries Trust Limited that the assets of the
trust, proposed to be acquired under the scheme, consist
of about 369 acres of freehold land and a two-thirds interest
in about 775 acres of freehold land (both wTithin the area
of the Kent coal field), the benefit of an agreement to work
about 12,000 acres of undersea minerals, options for leases
on mineral areas, and certain mineral rights, etc. These
assets do not include the interests of the Channel Collieries
Trust Limited in Kent Collieries Limited.

Richmond Gas Stove and Meter Company Limited.—
Dividend of 10 per cent, per annum (Is. per share), free of
tax, on ordinary shares for half-year (interim), payable
July 2.

Ruston, Proctor and Company Limited.—The report for
the year ended March 31 states that, the balance of profit,
after providing for estimated liabilities to the Government,
is £159,333. After deducting depreciation, directors’
remuneration, and interest on debentures, there is a balance
of £127,224. Add the balance brought forward from last
year, and deduct the dividend on preference shares and
interim dividend of 2^ per cent, on the ordinary shares,
there is left £110,350. The directors propose a final divi-
dend of 5$ per cent, on the ordinary shares, which, with
