The Sea Raiders Weary, Determined by H.G. Wells

About midnight excited hails were heard from a boat about a couple of miles out at sea to the southeast of Sidmouth, and a lantern was seen waving in a strange manner to and fro and up and down. The nearer boats at once hurried towards the alarm. The adventuresome occupants of the boat, a seaman, a curate, and two schoolboys, had actually seen the monsters passing under their boat. The creatures, it seems, like most deep-sea organisms, were phosphorescent, and they had been floating, five fathoms deep or so, like creatures of moonshine through the blackness of the water, their tentacles retracted and as if asleep, rolling over and over, and moving slowly in a wedge-like formation towards the southeast.
— H. G Wells


"As soon as the magic trick has been done the whole business of the fantasy writer is to keep everything else human and real. Touches of prosaic detail are imperative and a rigorous adherence to the hypothesis. Any extra fantasy outside the cardinal assumption immediately gives a touch of irresponsible silliness to the invention."The Scientific Romances of HG Wells ( 1933 )
