The sun soared over the gulf, where the water, covered with ships at anchor, and with sail- and row-boats in motion, played merrily in its warm and luminous rays. A light breeze, which scarcely shook the leaves of the stunted oak bushes that grew beside the signal station, filled the sails of the boats, and made the waves ripple softly. On the other side of the gulf Sebastopol was visible, unchanged, with its unfinished church, its column, its quay, the boulevard which cut the hill with a green band, the elegant library building, its little lakes of azure blue, with their forests of masts, its picturesque aqueducts, and, above all that, clouds of a bluish tint, formed by powder smoke, lighted up from time to time by the red flame of the firing. It was the same proud and beautiful Sebastopol, with its festal air, surrounded on one side by the yellow smoke-crowned hills, on the other by the sea, deep blue in color and sparkling brilliantly in the sun. At the horizon, where the smoke of a steamer traced a black line, white, narrow clouds were rising, precursors of a wind. Along the whole line of the fortifications, along the heights, especially on the left side, spurted out suddenly, torn by a visible flash, although it was broad daylight, plumes of thick white smoke, which, assuming various forms, extended, rose, and colored the sky with sombre tints. These jets of smoke came out on all sides--from the hills, from the hostile batteries, from the city--and flew toward the sky. The noise of the explosions shook the air with a continuous roar. Toward noon these smoke puffs became rarer and rarer, and the vibrations of the air strata became less frequent. "'Do you know that the second bastion is no longer replying?' said the hussar officer on horseback, 'it is entirely demolished. It is terrible!' "'Yes, and the Malakoff replies twice out of three times,' answered the one who was looking through the field-glass. 'This silence is driving me mad! They are firing straight on the Korniloff battery and that is not replying.' "'There is a movement in the trenches; they are marching in close columns.' "'Yes, I see it well,' said one of the sailors; 'they are advancing by columns. We must set the signal.' "'But see, there--see! They are coming out of the trenches!'
