At the time of the collapse of the Confederacy trade within the state of Alabama was subject to the following regulations: gold and silver was in no case to be paid for southern produce; all trade was to be done through officers appointed by the United States Treasury Department;[732] the state was divided into districts and sub-districts called agencies, under the superintendence of these Treasury agents, whose business it was to regulate trade, and collect captured, abandoned, and confiscable property; in making purchases of cotton, and other produce the agents were to pay only three-fourths of the value, or to purchase the produce at three-fourths its value, and then at once resell it to the former owner at full value, with permission to export or ship to the North; in order to get permission to sell, the owner must take the Lincoln amnesty oath of December 8, 1863; there was, besides, an internal revenue tax of two cents a pound, and a shipping fee of four cents a pound.[733] So for a month after the surrender the person who owned cotton near any port or place of sale had to sell to United States Treasury agents, or pretended agents, and have twenty-five per cent to fifty per cent of the value of his cotton deducted before it could be sent North. On May 9, 1865, a regulation provided that "all cotton not produced by persons _with their own labor_ or with the labor of _freedmen_ or others employed and _paid_ by them, must, before shipment to any port or place in a loyal state, be sold to and resold by an officer of the government ... and before allowing any cotton or other product to be shipped ... the proper officer must require a certificate from the purchasing agent or the internal revenue officer that the cotton proposed to be shipped had been resold by him or that 25 per cent of the value thereof has been paid to such purchasing agent in money."[734] This was in accord with the general policy of Johnson, at first, viz. to punish the slaveholding class and to favor the non-slaveholders. Cotton was then worth $250 or more a bale, and cotton raised by slave labor had to pay the 25 per cent tax--$60 to $75. However, the regulations ordered that no other fees were to be exacted after the fourth was taken. Nearly all the cotton not yet destroyed was in the Black Belt, and was raised by slave labor. The few people who had cotton raised by their own labor might sell it after paying the tax of three cents a pound, or $12 to $15 a bale.
