The sun disappeared behind a mountainous mass of leaden-colored clouds which rose rapidly in the southern and western quarters. To the eastward, also, the signs were threatening. Night came on suddenly as it does in the tropics. Soon the darkness enveloped us, a palpable veil. A noise like the march of a mighty host was heard, which proved to be the approach of a tropical flood, heralded by drops as large as marbles. It churned the still waters into a phosphorescent foam which rendered the darkness only more oppressive. The rain came down as it can come only in the Bight of Benin. The avalanche cooled us, reducing the temperature ten or fifteen degrees, giving us new life, and relieving our fevered blood. I told Mr. Block to throw back the tarpaulin over the main hatch and let our dusky friends get some benefit of it. In half an hour the rain ceased, but it was as calm and ominous as ever. I knew this was but the forerunner of something worse to follow, and we had not long to wait, for suddenly a blinding flash of lightning darted through the gloom from east to west, followed by one in the opposite direction. Without intermission, one blaze after another and thunder crashing until our eyes were blinded and our ears deafened, a thousand times ten thousand pieces of artillery thundered away. We seemed utterly helpless and insignificant. "How wonderful are Thy works," came to my mind. Still no wind; the brig lay helpless. Suddenly, as a slap in the face, the wind struck us,--on the starboard quarter, fortunately. "Hard-a-starboard." "Hanl aft port fore staysail sheet," I called. But before she could gather way she was thrown down by the wind like a reed. She was "coming to" instead of "going off," and I tried to get the main storm staysail down but could not make myself heard. She was lying on her broadside. Luckily the water was smooth as yet. The main staysail shot out of the boltropes with a report like a twelve-pounder, and this eased her so that if the fore staysail would only hold she would go off. For a few minutes all we could do was to hold on, our lee rail in the water; but the plucky little brig rallied a little, her head went off inch by inch, and as she gathered way she righted, and catching the wind on our quarter we were off like a shot out of a gun. I knew we were too near the vortex of the disturbance for the wind to hang long in one quarter, so watched anxiously for a change. The sea rose rapidly while we were running to the northward on her course, and after a lull of a few minutes the wind opened from the eastward, butt end foremost, a change of eight points. Nothing was to be done but heave to, and this in a cross sea where pitch, weather roll, lee lurch, followed one another in such earnest that it was a wonder her masts were not switched out of her.
