“Figure 4 represents a bill of six days’ value (called six days),” said Mr. Midith as he outlined a Marsian labor bill. “Besides the ornamental stamp which the bill contains, it bears the date of its issue, the number of the community which issued it, the country, or grand division, in which the community is located, its number, and its representative value of six days’ labor. We have bills of three sizes: One size representing _days’_ labor, one representing _hours_, and one representing minutes and seconds. “Now let us see whether we can understand the circulation of our labor-money. We have seen that every person, at the close of each month, sends his own labor-record to the ‘Com,’ the only place in the community where money is issued, and money is _never_ issued on anything else than these individuals’ monthly labor-records. So that all the money that is ever issued goes directly to the individual man, woman, or child, who labored for it, who produced the negotiable wealth which the money represents. “Now let us follow a bill in its circulation. We have seen that the individual can buy where he wishes, in his own family store, in his own community or out of it; he can also buy of another individual, or of a family, or of any community. We will say, for illustration, that Mary pays out one of her bills in any of the family stores of her own community. The family storekeeper, at the close of his day’s business, remits the bill to the ‘Com’ of his own community. Here it was issued and paid to Mary for labor performed; and here it is also canceled when it returns by stamping it on both sides, which is a mark of redemption, after which it is filed away. This bill is canceled because Mary drew the negotiable wealth which the bill represents out of the community’s storehouse. That is, she took her actual wealth she produced by her labor. When she received the money at the end of the month she took only the _representative_ of her wealth. Bear in mind that bills are canceled only at the ‘Com,’ not at the ‘big-houses.’ “Now let us go on further. Perhaps Mary paid out her bill in some other community than her own. Then the bill is sent to the ‘Com’ of that community where the purchase was made by the family which sold Mary the goods, but the ‘Com’ of that community does not cancel _our_ bills. The ‘Com’ of each community cancels only its _own_ bills. The community which gave Mary the commodities for her bill uses that bill the same as it uses its _own_ bills to buy of other communities; and these communities to buy of still others; so the bill keeps on circulating from one community to the other until it again reaches _our_ community, where it will be canceled, for we can not get the bill unless we redeem it with wealth, and all bills redeemed, as we have seen, are canceled at the ‘Com.’ Hence we may receive the money of any other community, and all other communities will accept our money.
