The power this gave Wilkinson, the way he had obtained it, and the use he made of it, gave an impetus to the separatist party in Kentucky. He was by no means the only man, however, who was at this time engaged in the river trade to Louisiana; nor were his advantages over his commercial rivals as marked as he alleged. They, too, had discovered that the Spanish officials could be bribed to shut their eyes to smuggling, and that citizens of Natchez could be hired to receive property shipped thither as being theirs, so that it might be admitted on payment of twenty-five per cent. duty. Merchants gathered quantities of flour and bacon, but especially of tobacco, at Louisville, and thence shipped it in flat-boats to Natchez, where it was received by their correspondents; and keel boats sometimes made the return journey, though the horses, cattle, and negro slaves were generally taken to Kentucky overland. [Footnote: Draper MSS. John Williams to William Clark, New Orleans, Feb. II, 1789; Girault to Do., July 26, 1788, from Natchez; Do. to Do., Dec. 5, 1788; receipt of D. Brashear at Louisville, May 23, 1785.] All these traders naturally felt the Spanish control of the navigation, and the intermittent but always possible hostility of the Spanish officials, to be peculiarly irksome. They were, as a rule, too shortsighted to see that the only permanent remedy for their troubles was their own absorption into a solid and powerful Union. Therefore they were always ready either to join a movement against Spain, or else to join one which seemed to promise the acquisition of special privileges from Spain. Robertson Talks of Disunion.
