Before proceeding with our trip to Pittsburg, I will bring together all the material points of information I have gathered relative to Cincinnati.

1. Its History and Progress.—The first year of the present century found here but 750 inhabitants. In 1810 there were 2, 540; in 1820, 9, 602; in 1830, 24, 381; in 1840, 46, 382. At present the population is estimated at 80, 000. The coloured population forms one twenty-fifth, or 4 per cent., of the whole. The native Europeans form one-fifth of the white population.

2. Its Trade and Commerce.—The principal trade is in pork. Hence the nickname of Porkapolis. The yearly value of pork packed and exported is about five millions of dollars, or one million of guineas! As a proof of the amazing activity which characterizes all the details of cutting, curing, packing, &c, I have been credibly informed that two men, in one of the pork-houses, cut up in less than thirteen hours 850 hogs, averaging 300 lbs. each, —two others placing them on the block for the purpose. All these hogs were weighed singly on scales in the course of eleven hours. Another hand trimmed the hams, 1, 700 pieces, in “Cincinnati style,” as fast as they were separated from the carcases. The hogs were thus cut up and disposed of at the rate of more than one per minute! And this, I was told, was not much beyond the ordinary day's work at the pork-houses. Steam-boat building is another important branch of trade in this place.
