SHEFFIELD, AUG. 14.

MR. BROWN'S BALLOON.
HIS ASCENT ON TUESDAY.

The circumstances connected with the late beautiful ascent of Mr. Brown, have been detailed to us by that enterprising aeronaut in the following terms :--

"Having formed a determination of ascending from the town of Sheffield, on the 10th of August, every preparation for inflation was made, which went forward comparatively we1l.   The balloon was fully inflated at twelve o'clock, but having been respectfully requested not to ascend till about three or four o'clock, I, of course, complied with their wishes. The weather continuing favourable, at three o'clock I commenced attaching the car.  The requisites being supplied, and the balloon being liberated, I s1owly ascended, carrying with me only three of four bags of ballast.  Perceiving that the balloon was de­scending over the lower part of the town, I was under the necessity of throw­ing out two of the bags, which effected a rapid ascent, and in ten minutes I lost sight of all terrestrial objects. The highest altitude I attained was about 2,166 yards, the barometer standing at 23. 10, and the thermometer at 48.  At this time, I was completely drenched in a snow shower, which continued a few minutes.  I now drank the good health of a11 absent friends, especially those who had rendered me such prompt assistance.  Here I was presented with a beautiful view of a flowing mass of clouds, resembling mountains of snow.  Shortly after, I distinctly heard the report of musketry, at the eleva­tion of 4000 feet from the earth.  The balloon took a E. S. E. direction.  On arriving in the neighbourhood of Tickhill, I was much gratified to behold people running from their houses in all directions after the balloon; I spoke through my trumpet, but was too far off to be heard.  I now began to descend very rapidly, owing to the density or the atmosphere; and having only one bag of ballast left, and being determined not to part with it, I pulled off my boots to throw out; but, luckily, the balloon rose in a very surprising manner, which rendered it unnecessary, at that time, to part with any thing.  I then passed through several layers of dense clouds, when it began to rain.  A favourable place for my descent not presenting itself, I was obliged to continue my voyage, till at length I arrived in the neighbourhood of Axholme, near Westwood Side, where I alighted in safety, in a rye field, the property of Mr. Pearson.  The first person who came to my assistance appeared rather frightened, but his fears having subsided, he used every exertion in his power to assist me.  When I had got the balloon packed up, and was about starting, several gentlemen, who had followed me from Tickhill, on horseback, came up, and kindly offered me their assistance.  They had been obliged to leave their horses behind, in consequence of their being unable to travel any further.  Having got all ready, and having proceeded a short distance with the luggage, I was joined by some peasants, who requested that they might carry the apparatus; whilst others, with different kinds of musical instruments, escorted me to the hamlet of Axholme, where I met with very kind treatment from John Belk, Esq. and many other gen­tlemen of respectability.  Having procured a proper conveyance, I proceeded on my way to Bawtry, where the bells were ringing a merry peal.  From there I proceeded to Sheffield, in a chaise and four.  On entering the town, which was about two o'clock in the morning, I was welcomed by my worthy townsmen with loud cheers, who took the horses from the carriage and drew me into the town, the band accompanying, playing many delightful tunes."
