This huge leviathan, like all the others of the herd, was long since dead.

Like a huge leviathan trapped in a net, the gas-bag writhed, twisted, bulged, shrank, gathered into a ball and sprang fiercely out.

To-day huge leviathans glide over the waves with a swiftness and safety deemed absolutely impossible fifty years ago.

The mist has gathered into long, whitish billows, that hang on the mountain sides, and like huge leviathans are slowly rolling down.
