=62. Mineral Labellers and Arrangers.= A lady could not easily make collections of minerals, but she might find it an absorbing occupation to arrange and label them. Few ladies in our country have given any study to mineralogy, and very few would be competent to form cabinets. Yet, for those that are, we doubt not employment of that kind could be found. The individual wealth of our country has not been sufficient to enable many to make extensive collections. The most that exist are connected with universities and other institutions of learning. They have been collected at different times--in fact, mostly formed by single specimens, added now and then. Individual collections have been formed in the same way. Individuals add to the cabinets of their friends, as they have it in their power. The most extensive collections in the United States are at the Patent Office, Washington, and in the National Academy of Science, Philadelphia. Mr. H., a mineralogist from Berlin, says: "In Berne, Switzerland, a man and his wife are mineralogists. On the husband's death the wife will continue the business." It must require many years' study and an extensive knowledge of chemistry to become a superior mineralogist. I would think considerable time and capital were requisite for a mineralogist to establish himself. Mr. H. makes exchanges of minerals for others, receiving, I suppose, a commission for doing so. A geologist writes me: "No women are employed in my business. It requires one half of a lifetime to become fitted for the duties of a geologist. A knowledge of engineering, and most of the natural sciences, is needed. Draughting in the office is the only part suitable for women."
