far shown an increase of nearly half upon the amount gathered in the preceding one. Thus the receipts at Philadelphia, for the first three months, were 4,370,714 dols., while they were 6,920,496 dols. for the second, and again 9,250,000 dols. for the third. This rate of augmentation coincides with the influx of population, and, as the emigration to the country is certain to be continued until the remuneration it affords for labour is brought to a level with the advantages offered elsewhere, there is no reason, so long as we are without accounts of an apparent limit to the field of operations, to anticipate anything else than a steady continuance of an improving ratio. So far from a limit having yet been found, each fresh exploration seems to develope new and more favourable localities, and an extended discovery of dry diggings lately alleged to have been made, together with the steps in progress elsewhere to crush the mountain ore by machinery, appears to hold out the prospect that, even with the approach of winter, there will scarcely be a suspension of the prevailing activity."--_Times, Nov. 19, 1850._ By the last accounts there was no less than a million sterling exported from California in _six days_. This amount of gold, great as it is, however, is by no means the whole of the supply which has been obtained. It is the regular measured amount only--what entered the custom-house books, and was exported in the entered traders. But who can estimate the amount which in those vast and desolate regions has been amassed by individuals, and made its way out of the country in their private possession, or secretly in shipments of which no account was kept? It is incalculable: like the plunder amassed during the sack of a capital or province, it may be guessed at, but cannot be ascertained with anything approaching to accuracy. Probably the amount thus acquired, but not entering any public records, may equal all that is ascertained from the custom-house books. But call it only a half, or fifty per cent, it will follow that last year the amount raised was upwards of £15,000,000, and this year (1851) may be expected to reach £17,000,000 or £18,000,000! If so, it will nearly double the annual supply of the precious metals for the use of the globe, which at present, from all sources, is between £16,000,000 and £17,000,000. It may with confidence be anticipated, that how secretly soever great part of this treasure may be smuggled or conveyed out of California, none, or at least very little of it, will be lost. It will all be carefully preserved, and sooner or later find its way into the circulation of the world, or be manufactured into the gold ornaments and vessels which minister to its luxury or magnificence. Nothing more is required to show the prodigious influence of this great change; beyond all question it will, in its ultimate effects, alter the face of the globe.
