Individual permits were sometimes given by President Lincoln, authorizing the bearers to go within the Confederacy, without restriction, and get cotton and other southern produce. Sometimes, after bringing it out, these people lost their cotton to United States Treasury agents, because the permission given by the President was not in accordance with the Treasury regulations. In north Alabama several agents got into trouble in this way. Lincoln, it seems, understood that the laws gave him authority to issue permits to trade within the Confederate lines.[511] In 1864, when cotton was selling at forty to fifty cents a pound in coin, numbers of Federal officers resigned in order to speculate in cotton. A former beef contractor who had grown rich in the cotton trade was said to have controlled almost the whole of Huntsville. Both hotels, the waterworks, and the gas works belonged to him, and there was complaint of his extortions.[512] Small packages, especially of quinine, were sent South through the Adams Express Company, which would guarantee to deliver them within the Confederacy.[513] This caused speculation, and it was finally stopped. Women passed through the lines and brought back quinine and other medicines concealed in their clothing. A druggist in middle Alabama determined to carry on a contraband trade in cotton and drugs. The South had prohibited private trade in cotton; the North forbade the sale of medical supplies to the Confederates. But following the example of many others, he went into north Mississippi, loaded a wagon with cotton, and carried it to Memphis, then held by the Federals, and sold it for a high price in United States money. He then exchanged his wagon for an ambulance with a white canvas cover, on which was painted the word "SMALLPOX" in large letters, and over which fluttered a yellow flag. He loaded the ambulance with quinine, ether, morphine, and other valuable drugs, and other articles of merchandise scarce in Alabama. The yellow flag and the magic word "SMALLPOX" kept people away, and, after many adventures, he finally reached home.[514] Only by such methods could the beleaguered people obtain the precious medicines. One of the last contracts on record in respect to trade through the lines was a deal made on January 6, 1865, by Samuel Noble and George W. Quintard, his agent, both of Alabama, to deliver several thousand bales of cotton to an agent of the United States Treasury.[515] There is evidence that some of the cotton was delivered.
