Crosby, in 1842, may be said to embrace the whole manufacturing business of the city in that year. Future statistics will show how it has increased, and will demonstrate the value of this addition to the trade; and to these we will now turn. The Louisville Directory for 1844-1845, compiled by N. Peabody Poor, and the best directory ever published here, gives a very complete and interesting view of the city for that year. As no events in any degree connected with the public interests, or of any especial political value, are referable to the period between this year and 1840, it will be as well to pass on at once to a notice of the results of these five years of steady progress. Beginning then with the population, which, it will be remembered, amounted in 1840 to 21,210, we find that in September, 1845, an actual census shows it to have reached 37,218 souls. Of these 32,602 were whites, 560 free blacks, and 4,056 slaves. The increase of five years is thus shown to amount to 16,008. Nor was it alone in the matter of population that such rapid progress had been made. The number of houses engaged in the wholesale and retail trade had increased from 270 to upwards of 500, and in addition to these purely commercial houses, there were then "12 large foundries for the construction of steam machinery; 1 large rolling and slitting mill; 2 extensive steam bagging factories, capable of producing about 2,000,000 of yards annually; 6 cordage and rope factories, some of which produced 900,000 pounds of bale rope annually, beside which there were several smaller rope walks for the making of sash cord, twine, &c.; 1 cotton factory; 1 woolen factory; 4 flouring mills, producing about 400 barrels daily; 4 lard oil factories; 1 white lead factory; 3 potteries; 6 extensive tobacco stemmeries, employing a large capital, where the leaf is stripped from the stem and re-packed for the English market; several tobacco manufactories; 2 glass cutting establishments; a large oil cloth factory; 2 surgical instrument makers; 2 lithographic presses; 1 paper mill; 1 star candle factory; 4 pork houses, which will slaughter and pack about 70,000 hogs annually; 3 piano forte manufactories; 3 breweries; 8 brick yards; 1 ivory black maker; 6 tanneries; 2 tallow rendering houses, rendering about 1,000,000 pounds annually; 8 soap and candle factories; 3 planing machines; 2 scale factories; 2 glue factories; 3 large ship yards, at which have been built some of the fastest running boats on the river; besides several factories of less note."[16] The simple statement of these facts furnishes a more convincing demonstration of the rapid and healthy progress of the city, than whole volumes of argument could afford.
