To sum up, the activity by which hoards are built up resolves itself into withdrawal of money from circulation by continually repeated sales, and simple hoarding or _accumulation_. In fact, it is only in the sphere of simple circulation and, especially, in the form of hoarding, that accumulation of wealth as such takes place, while, as we shall see later, in the case of other so-called forms of accumulation it is only a misnomer to call them by that name in mere recollection of the simple accumulation of money. All other commodities are hoarded either as use-values, in which case the manner of storing them up is determined by the peculiarities of their use-value: the storing of grain, e. g., requires special equipment; the accumulation of sheep makes one a shepherd; the accumulation of slaves and land creates relations of master and servant, etc.; the accumulation of particular kinds of wealth requires special processes different from the simple act of hoarding, and develops special individual traits. Or, wealth in the form of commodities is hoarded as exchange-value and in that case hoarding appears as a commercial or a specific economic operation. The one who carries on such operations becomes a dealer in corn, in cattle, etc. Gold and silver are money not through some activity of the individual who accumulates it, but as crystals of the process of circulation which goes on without any aid on his part. He has nothing to do but to put them aside, adding new weights of metal to his hoard, a perfectly senseless operation which, if applied to all other commodities, would deprive them of all value.[97]
