Nickel and Its Alloys

THE relative importance of things is a fascinating subject for thought. As we look about us we realize the Creator of all things has provided the metals for our use, each in the quantity needed-iron in vast quantities gold in small quantities. Had gold been given us in the quantities of iron, the mechanical age mould Eave been very different. You may find some pleasure in running over in your mind this question of the quantity available of an element and man's need of it in the scheme of things. Nickel in this sense is a middle group element. It was not essential to man's early development. Its usefulness dates back only about one hundred years. The quantity available to man has increased as his needs in- creased. On two occasions more nickel became available than was needed and on both of these occasions the ex- cess was soon absorbed by new and useful developments.
