              one yields an abundance of metals, it not only gives back to the owner the
                <lb/>
              money he has spent, but also gives a profit besides; certainly there will
                <lb/>
              be for him rich and profitable mining, if of the whole number, three, or four,
                <lb/>
              or more veins should yield metal. </s>
              <s>Very similar to this is the advice which
                <lb/>
              Xenophon gave to the Athenians when they wished to prospect for new
                <lb/>
              veins of silver without suffering loss. </s>
              <s>“There are,” he said, “ten tribes
                <lb/>
              of Athenians; if, therefore, the State assigned an equal number of
                <lb/>
              slaves to each tribe, and the tribes participated equally in all the new veins,
                <lb/>
              undoubtedly by this method, if a rich vein of silver were found by one tribe,
                <lb/>
              whatever profit were made from it would assuredly be shared by the whole
                <lb/>
              number. </s>
              <s>And if two, three, or four tribes, or even half the whole number
                <lb/>
              find veins, their works would then become more profitable; and it is not
                <lb/>
              “probable that the work of all the tribes will be disappointing”
                <emph type="sup"/>
              7
                <emph.end type="sup"/>
              Although
                <lb/>
              this advice of Xenophon is full of prudence, there is no opportunity for it
                <lb/>
              except in free and wealthy States; for those people who are under the
                <lb/>
              authority of kings and princes, or are kept in subjection by tyranny, do not
                <lb/>
              dare, without permission, to incur such expenditure; those who are endowed
                <lb/>
              with little wealth and resources cannot do so on account of insufficient funds.
                <lb/>
              </s>
              <s>Moreover, amongst our race it is not customary for Republics to have slaves
                <lb/>
              whom they can hire out for the benefit of the people

                <lb/>
              adays those who are in authority administer the funds for mining in the name
                <lb/>
              of the State, not unlike private individuals.</s>
