MY DEAR BOYS AND GIRLS: I want to show you to-day that there is a great difference in the value of things, even though they are made of the same material. In the second chapter of Genesis we are told, "And the Lord God formed man of the dust of the ground." So, you see that all men and women are made of the same material, yet men differ greatly, both in character and works.

Iron Products.

I have here some iron ore, some old iron, some nails; here are some clock springs, and here are some springs of watches. This iron ore is as it is dug from the earth. It is called the native iron, but mixed with it there is much earth and stone and dross, which must be separated from it in order to make it pure. This is done by casting the ore, together with limestone and other materials, into a huge furnace, where the fire is so intensely hot that all are melted and thus the iron is separated from the dross, or stone and earth, which is now mixed with the ore. When the iron is thus separated and molded into large bars, it is worth from a fraction of a cent to two cents per pound, according to quality and market price. After it has been cast into great iron bars, and is known as pig iron, it is afterward bought and melted over again and molded into the form of stoves and wheels, such as are used in factories, and a variety of other forms for manufacturing and other uses.
