NAUTICAL FACTS AND OCCURENCES. We some time ago noticed some proofs of the success of Smart's Patent Convex Propeller. A recent investigation into the merits of the invention elucidates the following sa- tisfactory and rather curious result :— " The two first steamers (says our correspondent) fitted with Mr Smart's paddle floats, about one year and a half since, have traversed a distance of nearly three times the circumference of our globe, and yet the floats, without a repair, have cabability of repeating the arduous undertaking. Voyages are also shortened at least one-tenth by their use."
