The adjacent strata are in most places considerably altered, and in some spots coaled with flakes of the green carbonate of copper. Recurring to what we have adduced respecting the copper ores of the State, it will be seen that they do not occur under circumstances to make the adventurous miner sanguine in pursuing to a costly issue, the indications of this metal which so frequently meet us throughout the red sandstone region. Numerous cases exist in other countries, it is true, where rich mines have been wrought in masses of ore that were not genuine veins, nevertheless, when the deposites arc like those common in the copper region of New Jersey, mining becomes peculiarly precarious. I have been thus explicit upon this subject, from a persuasion, that one main advantage to be anticipated from a rightly conducted geological survey, is the aid which it is capable of affording to enterprise, by stimulating every branch of wholesome industry, and checking rash and visionary undertakings. It should furnish a faithful statement of what every district possesses, and when necessary of what it does not possess. The one is as needful as the other, if our motive be to give the industry of the community a right direction. It may depress, and it cannot strengthen the spirit of useful enterprise, to permit capital to be misapplied to purposes that, when pursued, lead to loss and disappointment. When we contemplate the singular degree of uniformity which attends the copper ores of the State, their strict resemblance in point of composition, and the identity of the geological relations under which they are found, we are strongly impressed with the persuasion, that they all owe their production to one epoch, and to...
