Go on board--what and how? Had we come upon a river, a lake, had we discovered some inland sea? Was a vessel lying at anchor in some part of the interior of the earth? My curiosity was worked up to the very highest pitch. My uncle made vain attempts to restrain me. When at last, however, he discovered that my feverish impatience would do more harm than good--and that the satisfaction of my wishes could alone restore me to a calm state of mind--he gave way. I dressed myself rapidly--and then taking the precaution to please my uncle, of wrapping myself in one of the coverlets, I rushed out of the grotto. CHAPTER 27 THE CENTRAL SEA At first I saw absolutely nothing. My eyes, wholly unused to the effulgence of light, could not bear the sudden brightness; and I was compelled to close them. When I was able to reopen them, I stood still, far more stupefied than astonished. Not all the wildest effects of imagination could have conjured up such a scene! "The sea--the sea," I cried. "Yes," replied my uncle, in a tone of pardonable pride; "the Central Sea. No future navigator will deny the fact of my having discovered it; and hence of acquiring a right of giving it a name." It was quite true. A vast, limitless expanse of water, the end of a lake if not of an ocean, spread before us, until it was lost in the distance. The shore, which was very much indented, consisted of a beautiful soft golden sand, mixed with small shells, the long-deserted home of some of the creatures of a past age. The waves broke incessantly--and with a peculiarly sonorous murmur, to be found in underground localities. A slight frothy flake arose as the wind blew along the pellucid waters; and many a dash of spray was blown into my face. The mighty superstructure of rock which rose above to an inconceivable height left only a narrow opening--but where we stood, there was a large margin of strand. On all sides were capes and promontories and enormous cliffs, partially worn by the eternal breaking of the waves, through countless ages! And as I gazed from side to side, the mighty rocks faded away like a fleecy film of cloud. It was in reality an ocean, with all the usual characteristics of an inland sea, only horribly wild--so rigid, cold and savage. One thing startled and puzzled me greatly. How was it that I was able to look upon that vast sheet of water instead of being plunged in utter darkness? The vast landscape before me was lit up like day. But there was wanting the dazzling brilliancy, the splendid irradiation of the sun; the pale cold illumination of the moon; the brightness of the stars. The illuminating power in this subterranean region, from its trembling and Rickering character, its clear dry whiteness, the very slight elevation of its temperature, its great superiority to that of the moon, was evidently electric; something in the nature of the aurora borealis, only that its phenomena were constant, and able to light up the whole of the ocean cavern.
