This is the story of an Orleans boat in distinction from a Kentucky boat which was smaller and not so well finished.[54] The heavy up-river loads of the Orleans boats--sugar and molasses--were very important cargoes and illustrate the place the barge took in pioneer history; they were the freighters which carried on the larger rivers the heavy cargoes of a country fast filling with a new population. They plied, like the keel-boat, up and down stream but could not ascend the smaller rivers or reach portages of the larger streams because of their draught and size. There were, of course, small barges that could go wherever a keel-boat went; it was these that were common on certain portage path trades.[55] The small barge was practically a keel-boat (without running boards) save only in shape. The flat-boat was the important craft of the era of immigration, the friend of the pioneer. It was the boat that never came back, a downstream craft solely. The flat-boat of average size was a roofed craft about forty feet long, twelve feet wide and eight feet deep. It was square and flat-bottomed and was managed by six oars; two of these, about thirty feet long, on each side, were known as "sweeps" and were manned by two men each; one at the stern, forty or fifty feet long including its big blade, was called the "steering oar;" a small oar was located at the prow, known as the "gouger," which aided in steering the boat in swift water. One man only was needed at the steering oar and at the gouger. "Kentucky" and "New Orleans" were the significant names for the old-time flat-boats, for Kentucky and New Orleans were the destinations of the large majority. The nominal difference between a Kentucky and New Orleans boat was that the former was commonly roofed only half over while the latter was stronger and was entirely covered with a roof. How to buy or build a "flat" was the first query of the pioneer father as he finally arrived at one of the ports on the upper Ohio. Often several families joined together and came down the river on one flat-boat, a motley congregation of men, women, children and domestic animals surrounded by the few crude, housekeeping utensils which had been brought over the mountains or purchased at the port of embarkation. Perhaps all of the details which engrossed a prospective pioneer's attention are suggested in the previous quotations from _The Navigator_. These Kentucky "broadhorns," or "broadhorn flatboats" as they were also called, almost invariably carried a tin horn by means of which some one on board would announce their arrival or make known their whereabouts in a fog. This weird music, reverberating from hill to hill, was heard far and wide and was welcomed by the country people.
