He then made numerous expeditions from various places in
Pennsylvania and New Jersey. In 1855 he made several ascents from
Wilmington, Delaware, and on 16 June 1856, ascended from
Wilkes-Barre, Pennsylvania, but in descending was dashed to the earth and rendered insensible. During 1856-57 he made ascents from
Providence, Rhode Island, and other places in
New England, and, on 15 August, he went up from
New Haven, Connecticut, in his balloon “Queen of the Air,” which subsequently became famous from his ascents made from
Boston. At an ascent on 1 September 1858, he experimented with the use of a drag rope as a guide. In starting, he allowed 75 pounds of rope to trail along the ground. As the balloon gradually became heated by the sun, its buoyant power was increased without discharging ballast, and by the time five miles had been traversed the rope was lifted from the ground, and it continued to be lifted until a height of two miles had been reached. After a passage of nearly thirty miles, the drag rope was detached, and he continued a similar distance farther. In June 1859, he made an ascent from
Charlestown, Massachusetts, landing in
Belmont, and on 4 July following he made an ascent from Boston. On another occasion he ascended from
Boston Common with a party, and alighted in
Melrose, where a long rope was procured, and he treated some of the passengers to a bird's-eye view of the village by moonlight. While the balloon, with five young women, was in the air, it escaped, but after a few miles the descent was safely made. On 4 July 1868, he made an ascent from
Buffalo, New York, with five persons. The start was excellent, but the balloon was carried out over
Lake Erie, where, in efforts to navigate it, by means of an undercurrent, to reach the land, the car twice struck the surface of the water. King reached the land, and then began a voyage that finally ended on the top of the
Alleghany Mountains late at night. As the balloon struck, the
anchor was thrown out, but it rebounded, passing over a tall
pine tree, the top branches of which caught the anchor. The rope being comparatively short, the party were not able to reach the ground. The night was dark, and the nature of the surface beneath them was unknown, so they concluded to remain all night in the tree. When daylight came, the anchor rope was cut loose and the balloon landed with perfect safety. On 19 October 1869, King ascended from
Rochester, New York, with his monster balloon the “Hyperion,” in the presence of nearly 50,000 persons, carrying a party of seven. The weather was unfavorable, the wind boisterous, threatening clouds flew across the sky, flurries of snow were frequent, and the cold was searching. In four and a half minutes, although gas had been discharged from the valve, they entered a snow-cloud. The balloon moved at the rate of forty miles an hour, the cold was intense, night came on, and the party were in the midst of a driving
snow storm. The weight of snow that collected on the top of the balloon drove it to the ground, and a forced landing in an open field was made in the
squall; but the anchor did not hold, and the balloon bounded over a piece of woods, alighting on the other side. Here the anchor held for a while, the gas escaping from the valve, but, unfortunately, two of the party got out of the basket, and the balloon, thus lightened, broke loose and bounded upon a side hill and at last ran against a tree, a huge rent being made in the machine, so that the gas escaped almost instantly. The party had landed near
Cazenovia. During a subsequent series of ascents in the southern states, King had many strange experiences; the people, unfamiliar with such sights, were at a loss to account for his strange descent from the clouds. In February 1870, he ascended from
Augusta, Georgia, and after a journey of 130 miles descended, although not until his balloon had become damaged and he had been precipitated to the ground from a height of nearly 60 feet. In July 1872, he ascended from Boston Common, and was carried out to sea, but, after descending until the drag rope trailed through the water, a
yacht was met with and the rope tied to its mast. The balloon soon towed the vessel in to the shore and landed. ==Scientific interest==
