per monton of twenty quintals. An increase either in the quality, or the quantity, was required in order to cover the expences, which, in so extensive an undertaking, were of course considerable. It was calculated, however, that four hundred cargas more,[1] (making 1000 in all,) even of the same poor ores, would not only cover the "Memorias," but leave 1,000 dollars profit weekly. The Miners of Zacatecas entertained little doubt with regard to the issue of the enterprise of the Company at San Acasio, for no mine in the district bears so high a character: but the time requisite in order to reap the full advantage of the investments made is uncertain, from the vast extent of the works, which occupy a space of 800 varas upon the course of the vein. Mr. Alaman seemed to be of opinion in 1826, that nearly the whole of 1827 would be required to bring his operations to a conclusion, and some allowance must always be made for additional delays. In the course of the present year, however, the result must be known.
The Company is in possession of two Haciendas de beneficio; that of San José in the town of Zacatecas, with fourteen Arrastres, and Cinco Señores,
- ↑ It must be recollected that profits depend upon two distinct causes, the great abundance of poor ores, yielding a given profit upon an immense mass of "Montones," or a less copious extraction of rich ores, raised by fewer hands, and "reduced" with less labour. It is in the first that the great riches of Zacatecas and Guanajuato have principally consisted.
