MINES SAFETY RESEARCH.
The safety in mines research station at Harpur Hill, Buxton, was officially opened last month by Lord Chelmsford, chairman of the Miners' Welfare Committee,

THE MEAT “WAR" TO END.
RIVAL COMPANIES COME TO AGREEMENT.
HOUSEWIVES TO PAY MORE.
The end of the "meat war,"
which has lasted more than two years, between British and Ameri-' con importers of chilled Argentine beof, and is stated to have lost nearly $16,000,000, in at last with- in sight, the Westminster Gazette understande.
Negotiations have resulted in Isubstantial agreement and an announcement can be expected Shortly.
Among the problems relating to safety in coal-mining, that of "the behaviour of coal dust in mine ex- plosions has proved the most diff cult of solution, for the roason, no doubt, that the phenomena of con!- dust explosions can satisfactorily bo studied experimentally only An expert points out that peace. when they are of a magnitude com will mean that the public will have parable with that of an actual to pay higher' prices, but it may inine explosion."

might result if the blank at the closed end of the gallery were blown off during an experiment, a strong ramp, composed of lime stone rock and concrete faced with timber, has been erected a few feet behind the gallery. Instru- ment cabins are fixed along the side of the gallery at intervals of 100ft "A study of the develop ment of a coal-dust explosion de mands the determination, at as many points as possible in the path of the explosion, of the speed of propagation of flame. the rate of development of pressure, and the maximum pressure attained."
Two Immediate Problems, "Two problems have been select- ed for immediate study. It was established years ago that dry coal dust can propagate an explosion without the presence of inflam- mable gas, and that the admixture of incombustible dust with the conl dust renders it much more dimeult to ignite. The forthcom- ing experiments are intended to. show the effect of the presence of small percentages of fire damp in the air on the liability to ignition of mixtures of coul dust and in- combustible dust. "The results nbtained by previous workers are
This year the fight was so bitter that it was prophesied that the comparatively small Smithfield & Argentine Company would be crushed by its tremendous rivals. Nevertheless, the firm scored a signal success by obtaining a con- tract to supply the Co-operative Wholesale Society, with 15,000,000 members, with all the Argentine meat it required.
One consequence of the agree- ment la bound to be a considerable increase in the price of chilled beef, an authority on the subject said yesterday. Housewives will have to pay 1d. and 2. more per pound. The increase may be even greater.
