A good deal of ballast was discharged almost immediately over the inclosure, after which the huge machine rose rapidly, but not so suddenly as to break the even current of its course,' and was soon lost in the clouds. The subjoined engraving represents the ascent of the balloon, with the parachute attached: [Illustration] The account given by Mr. GREEN, of the voyage, is one of intense interest; and we regret that our space compels us to abridge it of many exciting particulars. Mr. Cocking had desired to reach an elevation of one mile and a quarter, before detaching himself from the balloon, and commencing his descent. At first, the upward progress was slow, and it became necessary to discharge several pounds of ballast through a tube, constructed for the purpose, leading from the balloon over the outer edge of the parachute. The lower end of this tube subsequently became detached, by the swinging to and fro of the parachute, and the ballast was thrown over in small bags, not without danger to the people on terra firma. The balloon soon entered a tier of clouds, and the aëronauts were lost to the earth, though still some three thousand feet lower than the desired elevation of Mr. Cocking, who now manifested much anxiety, frequently requesting of the 'upper house' to know when every addition of five hundred feet had been attained. When at the height of about five thousand feet, and in a range with Greenwich, the intrepid occupant of the parachute, fearing that he would be unable to reach the earth until after dark, said to his companions in the balloon above him, 'I shall soon leave you,' adding, that the practical trial, thus far, had borne out the sanguine calculations he had made, and that he never felt more comfortable or delighted in his life, at the same time bidding Mr. Green and his companion 'good night,' who returned the courtesy, with hearty good wishes for his safe descent. A sudden jerk ensued, the parachute was liberated, and the balloon instantly shot upward with the velocity of a sky-rocket, while the gas, rushing in torrents from the lower valve by reason of the pressure of the dense atmosphere upon the top of the balloon, nearly suffocated the aëronauts, and rendered them totally blind for four or five minutes. But for a bag, containing fifty gallons of atmospheric air, into which were inserted tubes from which they breathed it, both Mr. Green and his companion must inevitably have perished. So soon as the thermometer could be examined, it was ascertained that they were above four miles and a quarter from the earth! Yet even this was nothing like their greatest altitude, since they were now effecting a rapid descent. A wise precaution in enlarging the lower valve, alone prevented the bursting of the balloon, from the great pressure of the atmosphere. The aëronauts suffered severely from the cold, the thermometer indicating twenty-four degrees below the freezing point. 'We were at this period,' says Mr.
