Years may add to the bulk, and, therefore, the richness of its value; but until man, by his labor of muscle and brain, has brought it forth, it has no value whatever.
To have value, it must become an object of barter, of circulation, in short, of exchange.

As its value depends upon its utility, so when it can no longer be used it again becomes a useless mass of perishable wealth.

It is the product of labor, pure and simple.

Speaking on "Management of the Banks" (footnote p.

223), in his work on _Labor and Capital_, Edward Kellogg says:-- All who become rich by speculations in bank, state and other stocks, gain their wealth at the expense of the producing classes; for no increased production is made by the changing market value of these stocks.
