[Morell, Wm H.]:


[np: 1846] 7, [1 blank] pp. Caption title [as issued]. An untrimmed, uncut, folded folio leaf. Some dustsoil and wear. Ink signature on last page of Senator Wm. Upham [some bleedthrough]. Good to Good+. Morell, a prominent civil engineer, wants to tackle a major problem encountered on the Ohio River, that "great thoroughfare from East to West, and from North to South...The falls of the Ohio, making within two miles a descent of twenty-five feet, prevent the passage of steamboats for more than three fourth of the year, and steamboats of the larger class for a still greater period of time." A Canal built to solve this problem is ineffective: it is "so shallow, so narrow, and the locks so short." Captain Cram's plan to enlarge the Canal is insufficient. Morell suggests, and explains, his proposal: "a dam and locks at the foot of the falls-- the dam to be high enough to raise the water above, so as to back up over every part of the falls high enough for boats of five feet draft to pass at the lowest stages."
