THE MELBOURNE RECORD
i MELBOURNE, Apiil 23. The seismograph at the Observatory shows that the first indication of a termo) ■\va a at half-past 11 at night on the 18th. i It gradually increased until the period of
greatest intensity, which was at U.hl on the morning of the ISth". Thereafter it gradually lessened, until at 2.30 the same morning the line resumed its normal position. Comparing the times, Mr Baracchi, the Government astronomer, computes that it took "80 minutes to travel ' from San Francisco to Melbourne, at the, rate of two miles a second, which is not an unusual pace. Cases are' on record where the speed was seven miles. The seismograph showed altogether ten impulses," the ninth being the most strongly marked. The most striking of the discoveries made is the record of another earthquake, indicating that it originated at a considerable distance fiom Melbourne. Professor Baracchi is greatly surprised that no reports of this disturbance have yet reached Melbourne. He does not regard seriously the statements of various persons who believe they felt the San Francisco shock in Melbourne. The tremor in Melbourne was so slight as to be unappreciable.
