"it warn't no slouch of an idea; and it warn't no slouch of a grindstone nuther; but we allowed we'd tackle it. it warn't quite midnight yet, so we cleared out for the mill, leaving jim at work. we smouched the grindstone, and set out to roll her home, but it was a most nation tough job. (from adventures of huckleberry finn by mark twain).what is a likely purpose of the author's use of dialect to narrate the story?
