c enterprise. Accordingly, we find that shortly
after the battle of Marathon, the yearly profits of the mines were
immense. We learn from the researches of one of those eminent Germans
[36] who have applied so laborious a learning with so subtle an
acuteness to the elucidation of ancient history, that these mines were
always considered the property of the state; shares in them were sold
to individuals as tenants in fee farms, and these proprietors paid,
besides, an annual sum into the public treasury, amounting to the
twenty-fourth part of the produce. The state, therefore, received a
regular revenue from the mines, derived from the purchase--moneys and
the reserved rents. This revenue had been hitherto divided among all
the free citizens, and the sum allotted to each was by no means
inconsiderable, when Themistocles, at an early period of his career
(before even the ostracism of Aristides), had the courage to propose
that a fund thus lucrative to every individual should be appropriated
to the national purpose of enlarging the navy. The feud still carried
on with the Aeginetans was his pretext and excuse. But we cannot
refuse our admiration to the fervent and generous order of public
spirit existent at that time, when we find that it was a popular
leader who proposed to, and carried through, a popular assembly the
motion, that went to empoverish the men who supported his party and
adjudged his proposition. Privileged and sectarian bodies never
willingly consent to a surrender of pecuniary benefits for a mere
public end. But among the vices of a popular assembly, it possesses
the redeeming virtue to be generous. Upon a grand and unconscious
principle of selfishness, a democracy rarely grudges a sacrifice
endured for the service of the state.

The money thus obtained was devoted to the augmentation of the
maritime force to two hundred triremes--an achievement that probably
exhausted the mine revenue for some years; and the custom once broken,
the produce of Laurion does not seem again to have been wasted upon
individuals. To maintain and increase the new navy, a decree was
passed, either at that time [37], or somewhat later, which ordained
twenty triremes to be built yearly.

VII. The construction of these vessels, the very sacrifice of the
citizens, the general interest that must have attached to an
undertaking that was at once novel in itself, and yet congenial not
more to the passions of a people, who dail
