The Kentucky Lock Factory is another establishment deserving especial notice. The work made at this factory is surpassed in quality by none in the West. Locks of every description from those of the prison, the Bank and the safe, to the smallest mortise latch, are manufactured with equal care and fidelity. The Fire-Proof Safe, which has a well established reputation everywhere, is also made here. Iron doors and frames for bank vaults and prisons us well as sliding door locks and trimmings also form a part of the daily work of the factory. This concern, under the charge of Mr. Aug. C. Harig has for a long time enjoyed the confidence and patronage of this community, and it will doubtless, under its present management, continue to increase in public favor. In addition to articles of their own manufacture, Messrs. H. & S. offer for sale an excellent assortment of Builders Hardware. A. TIENSCH, Manufacturer of Mathematical and Philosophical Instruments, NO. 97 THIRD STREET. In the same building with the factory noticed above, may be found the instrument shop of Mr. Tiensch. In this exceedingly complex and scientific manufacture, this gentleman is very eminent. The most delicate manipulations of his art are performed by him with singular accuracy and facility. Manufactories of this kind are rare in the American cities, nor is the demand for these articles very great. Mr. T. is therefore able to furnish the proceeds of his manufacture to buyers who are scattered ever a large surface of country. He keeps on hand a stock of the instruments in most common use and is thoroughly competent to the successful manufacture of any article in his line which may be desired by the scientific man. His factory will doubtless grow with the growing wants for articles of this description in this great city. The curious in such matters will find his shop well worthy of a visit. HULL & BROTHER, Book & Job Printers, Binders, AND PUBLISHERS, 83 & 85 Fourth Street, between Main and Market. This firm commenced business in this city in the year 1844. It has gradually grown, from a small beginning, until it stands second to no establishment in the West, either for facilities or workmanship. Although its principal business is that of Book, and the finer kinds of Job Printing, yet at this office are issued two weekly papers, and three monthly periodicals--making an average of over _ten thousand periodicals weekly_. The Proprietors being both practical men, (having been all their lives engaged in the business, and understanding thoroughly every department of it,) they have been enabled to carry the Art of Printing to a perfection that would surprise and astonish the spirits of Faust and Guttemberg, were they to arise from their graves, as much as it pleases and attracts the lovers of the beautiful of the present day.
