A story is recorded involving James Pillars and his step-son, James Hughs. The story took place about the Fall of 1798 or the Spring of 1799 in Randolph County, Illinois. James Hughs, being a man of energy and business capacity, engaged in making salt, at the mouth of Saline creek, in Missouri, opposite Kaskaskia, a place where the early settlers were in the habit of boiling salt. This salt he conveyed to the falls of the Ohio in what were then called Pirogues, small flat-bottomed boats, which were polled and hauled along the river. Trading the salt he brought back such articles as were needed for use and to barter. On one of these trips he met his future wife, a lady named Rachel Hall, and engaged to marry her at the conclusion of his next trip. His step-father, James Pillars, having by some means gotten information of the matter, unknown to Mr. Hughs, made his arrangements to surprise him, so when James Hughs started down the river with his cargo of salt, Mr. Pillars, taking two horses, besides the one he rode, cut across the country and met young Hughs at the falls, who being thus surprised, inquired the reason of his unlooked-for presence, and was told by Mr. Pillars that, expecting a marriage, he had brought the horses so that James Hughs might ride with his wife to her new home. The party rode back together, camping out at night, their only bed being the blankets carried on horseback, and their food such as could be prepared by the way with the camp kettle.
