Capital assumes but two economical forms, namely, Circulating Capital and Fixed Capital. _Circulating Capital is all those capitalized products, whether commodities or credits, the returns for the sale or use of which are derived at once and once for all._ All circulating capital will be found in one or other of the following sub-forms: (1) raw materials; (2) wages paid out in view of an ultimate profit; (3) completed products on hand for sale; and (4) products bought and held for the sake of resale. The crucial test of circulating capital is the question, Are the returns to be secured by the single use or single transfer of that particular product? Tools, for example, in the hands of him who has manufactured them for sale is circulating capital. _Fixed Capital is all those capitalized products, which are purchased or held with a view of deriving an income from their delayed and repeated use._ All fixed capital will probably be found in one or other of the sub-forms following: (1) tools and machinery in use; (2) buildings used for productive purposes; (3) permanent improvements in land parcels; (4) investments in aid of locomotion and transportation; (5) products rented or retained for that purpose; and (6) the national money considered as a whole. 2. We will next look at the essential CONDITIONS of the production of Commodities. These are also three, as are the Requisites, namely, _Association_, _Invention_, _Freedom_. More or less will men make and sell to one another commodities in any state of society, in which there is permitted any considerable degree of association of men with men locally or commercially, in which is encouraged in any way the universal spirit of invention or the desire to get hard things done easier, and in which some degree of liberty of action and security of property and equality of privileges is guaranteed; but it is very plain, that the production of commodities will increase in all directions and become the greatest in that age and country when and where are allowed the closest ties of human association both in place and in commerce, the freest scope and largest rewards of inventive genius, and the highest possible degree of liberty and security and equality of rights. Let us illustrate from a state of things in the southern half of the United States during the first half of the nineteenth century. For the most part the land owners lived on isolated plantations widely separate from one another, these plantations were cultivated by gangs of slaves, a system that tends to bring all manual labor into contempt, the poor whites scattered in hamlets felt themselves above the slaves and beneath the masters, intercourse between the three classes was little, opportunity to better essentially their condition was denied to all three alike, there were but few cities sprinkled over the vast territory and these relatively small, the only commodity produced on a large scale was raw
