APRIL 16TH. To-day, looking upward as well as I could, through each of the side windows alternately, I beheld, to my great delight, a very small portion of the moon's disk protruding, as it were, on all sides beyond the huge bulk of the balloon. My agitation was extreme, for I had now little doubt of soon reaching the end of my perilous voyage. Indeed, the labor required by the condenser had increased to such a degree that I had scarcely any respite from exertion. Sleep was a matter nearly out of question. I became quite ill, and my frame trembled with exhaustion. It was impossible that human nature could endure this state of intense suffering much longer. APRIL 17TH. This morning proved an epoch in my voyage. It will be remembered that on the thirteenth the earth had diminished; on the fourteenth, it had still further dwindled; on the fifteenth, a still more rapid decrease was observable; and on retiring for the night of the sixteenth, the earth had shrunk to small size. What, therefore, must have been my amazement, on awakening from a brief and disturbed slumber on the morning of this day, the seventeenth, at finding the surface beneath me so suddenly and wonderfully increased in volume as to seem but a comparatively short distance beneath me! I was thunderstruck! No words can give any adequate idea of the extreme, the absolute horror and astonishment, with which I was seized, possessed and altogether overwhelmed. My knees tottered beneath me--my teeth chattered--my hair started up on end. The balloon then had actually burst! These were the first ideas which hurried through my mind. The balloon had burst! I was falling--falling with the most impetuous, the most wonderful velocity! To judge from the immense distance already so quickly passed over, it could not be more than ten minutes at the farthest before I should meet the surface of the earth and be hurled into annihilation! But at length reflection came to my relief. I paused, I considered, and I began to doubt. The matter was impossible. I could not, in any reason, have so rapidly come down. Besides, although I was evidently approaching the surface below me, it was with a speed by no means commensurate with the velocity I had at first conceived. This consideration served to calm my mind, and I finally succeeded in looking at the matter in its proper point of view. In fact, amazement must have fairly deprived me of my senses when I could not see the vast difference in appearance between the surface below me and the surface of my mother earth. The latter was indeed over my head and completely hidden by the balloon, while the moon--the moon itself in all its glory--lay beneath me and at my feet!
