The cylindrical lifeboat kept perfectly water-tight, and though thrown into the water in many different positions--sometimes tumbled in on its prow, at other times on its back (the deck being undermost), it invariably righted itself.
The screws fore and aft worked well, and were capable of being turned by human labour or by steam power.

Now that such large freights of passengers are carried by ocean-going ships, it would seem necessary that some such method should be adopted of preserving life at sea; for ordinary lifeboats, which are so subject to destructive damage, are often of little use in fires or shipwrecks, or other accidents on the ocean.
