To the present generation of mining engineers there
are few books better known than Kerr’s Practical Coal
Mining, and its popularity is not a mere matter of
sedulous advertisement; it may be more justly attri-
buted to the sound basis of practical utility that domi-
nates it, and to the dogged resistance which the author
has opposed to the temptation to wander from his course.

The ramifications of coal mining to-day are so great
that the author who sets out to write about it can, if he
chooses, cover an almost boundless range of subjects, to
his own destruction be it said; for the limits of space
will bring him to a close with many things excluded
that should have been included. In writing a manual
for managers, under-managers, and colliery engineers,
such as this, it is difficult to draw the dividing line. To
take one phase of the profession only : Machinery and
appliances are in daily use in or about a mine in which
the manager is only interested in the capacity of user.
To enter into a technical discussion of their construc-
tion is a sheer waste of time in a work that deals with
the practical side of mining. Otherwise we might just
as logically introduce chapters on the breeding of pit
ponies, or the manufacture of soap.

For the reasons given above, we are prepared not to
blame, but rather to commend, Mr. Kerr for dealing but
sparingly with some latter-day developments, such as
electric haulage; for, although it may be useful for the
manager to know what electricity can do in this direc-
tion, descriptions and illustrations of different plants
will not help him greatly in his work.

' On the other hand, the Coal Mines Act of 1911 alone
justifies the issue of this new edition, for it profoundly
affects the practice of mining in innumerable directions.
The author has succeeded in covering this new ground
admirably.

In the earlier chapters the subjects of boring and sink-
ing are well treated, although some particulars might
have been added in regard to the Continental systems of
boring, and the cementation process of sinking, since
these are now being employed very generally in this
country where operations have to be carried out in
water-bearing strata. The chapter on explosives has
not been brought so rigorously up to date as it might
have been, as the author still speaks of the Woolwich
test; and, on the whole, the chapter is not as useful to
the student as some others in the book.

The chapter on coal cutting is excellent, as are those
on the transmission of power and modes of working.
Much of the latter is obviously based upon the author’s
first-hand experience in Scotland. There is also a
splendid chapter on timbering. That on winding, again,
is thoroughly up-to-date, and we do not blame the
author for omitting specific reference to all the multi-
tudinous types of overwinding controllers, or the latest
superfluities of the electric winder.

Under the heading of haulage some representative
types of conveyors are dealt with, although some refer-
ence might have been made to the swinging and jigging
types that are popular on the Continent. There is a
lengthy chapter on pumping; and in the chapter on
ventilation the author has brought his matter well up
to date; and to that on safety lamps the same observa-
tion may be applied, many of the best known types of
electric lamps being illustrated. Sections on rescue
apparatus, surface arrangements, and surveying com-
plete the book.

It may be repeated that this manual is one that any
instructor in mining can place in the hands of his
pupils with perfect confidence. Mr. Kerr is a scrupu-
lous and careful writer, in addition to being a mining
engineer of high capacity and experience. His book
refers more particularly to British mining methods, and
is confined mainly to those which have survived the
proof of experience. We do not think it is any the worse
for not divagating into channels that probably will never
be traversed by its readers. The book is produced in
Messrs. Griffin’s best style, the illustrations are clear,
the type and paper good, and there is a thoroughly
serviceable index.

Duke Bar Motor Works, off Briercliffe-road, Burnley, in the

THE FREIGHT MARKET.

Outward chartering has been considerably more active this
week. The termination of the Spanish strike is liberating a
good deal of tonnage, and thereby easing the scarcity which
has existed during the dispute. On the North-East Coast
rates are relatively high. Coasting business is being done
at about 3s. 3d. to London from the Tyne, and from 3s. 9d.
to 3s. 10Jd. to Hamburg. The Baltic has Cronstadt at from
4s. 7^d. to 4s. 9d., and St. Petersburg at 5s. 3d. The Bay
is worth 6s. to Bayonne, with Bordeaux at 6s. 3d. The
Mediterranean ranges from 8s. to 8s. 3d. to Genoa. At
South Wales business has been fairly brick. Bates for the
Mediterranean are very irregular, and handy-sized boats are
in better request than are the larger vessels. The Biver
Plate is steady. The Bay and coasting ports are unaltered.
At the Clyde business is quiet, at late rates. The Humber
market is firm. Homewards, the American market is quiet,
with a limited demand. Grain tonnage meets with a fair
enquiry at steady rates from Canadian ports. Cotton ton-
nage is neglected. Timber orders are few, and figures favour
shippers. Time charter business is inactive. At the Black
Sea chartering has been busy, but is now quieter for June.
Grain, however, is coming forward freely, and, as prices in
consuming markets are strong, prospects are encouraging.
The Eastern and Australian demand is slow, and rates are
upheld with difficulty. The Mediterranean and ore trades
are steady. The Baltic is quiet, but firm. The Bi ver Plate
is very dull.
