Henry M. Collins, of the City of Pittsburg, stands among the men of note; and we could not complete this list of usefulness, without the name of Mr. Collins. Raised a poor boy, thrown upon the uncertainties of chance, without example of precept, save such as the public at large presents; Mr. Collins quit his former vocation of a riverman, and without means, except one hundred and fifty dollars, and no assistance from any quarter, commenced speculating in real estate. And though only rising forty, has done more to improve the Sixth Ward of Pittsburg, than any other individual, save one, Captain W., who built on Company capital. Mr. Collins was the first person who commenced erecting an improved style of buildings; indeed, there was little else than old trees in that quarter of the city when Mr. Collins began. He continued to build, and dispose of handsome dwellings, until a different class of citizens entirely, was attracted to that quarter of the town, among them, one of the oldest and most respectable and wealthy citizens, an ex-Alderman. After this, the wealthy citizens turned their attention to the District; and now, it is one of the most fashionable quarters of the City, and bids fair to become, the preferred part for family residences. Mr. Collins' advice and counsel was solicited by some of the first lawyers, and land speculators, in matters of real estate. He has left or contemplates leaving Pittsburg, in April, for California, where he intends entering extensively into land speculation, and doubtless, with the superior advantages of this place, if his success is but half what it was in the former, but a few years will find him counted among the wealthy. Mr. Collins is a highly valuable man in any community in which he may live, and he leaves Pittsburg much to the regret of the leading citizens. Without capital, he had established such a reputation, that his name and paper were good in some of the first Banking houses. Owen A. Barrett of Pittsburg, Pa., is the original proprietor of "B.A. Fahnestock's Celebrated Vermifuge." Mr. Fahnestock raised Mr. Barrett from childhood, instructing him in all the science of practical pharmacy, continuing him in his employment after manhood, when Mr. Barrett discovered the "sovereign remedy" for _lumbricalii_, and as an act of gratitude to his benefactor, he communicated it to him, but not until he had fully tested its efficacy. The proprietor of the house, finding the remedy good, secured his patent, or copy right, or whatever is secured, and never in the history of remedies in the United States, has any equaled, at least in sale, this of "B.A. Fahnestock's Vermifuge." Mr. Fahnestock, like a gentleman and Christian, has kept Mr. Barrett in his extensive House, compounding this and other medicines, for sixteen or eighteen years.
