QUESTIONS.--Can you name different things made from iron? Is a horse shoe as valuable as a watch spring? What makes the difference in their value? How are iron and steel refined, or made more valuable? Are unrefined and untaught boys and girls all quite alike? What makes them become different? Do some boys and girls become more useful and valuable in the world than others? What causes the difference? Would the iron cry out against being refined? Do boys and girls object to being taught and disciplined? How does the Bible say that God refines us? Can the refiner see his image in the melted metal? Does God want to see His own image reflected in us? [Illustration: "Joseph in the Pit."] A POCKET RULE. HOW GOD MEASURES MEN. SUGGESTION:--Objects: A yard-stick, pocket-rule, tape-measure and any measure or scales convenient. Use the measures and scales for measuring the height and weight of the different children, and explain to them that if they continue to grow, they will eventually become full grown men and women. So God measures them to-day in moral things, and if they will learn what God requires and be obedient to their parents, they will increase in moral stature as well. MY DEAR YOUNG FRIENDS: I am sure you will be able to tell me what these are which I hold in my hand. This you would call a yard-stick; the other, because it folds, you would call a pocket-rule, and here is another, which you would call a tape-measure. [Illustration: Yard-Stick, Pocket-Rule and Tape-Measure.] Now, if I were going to measure any of you, to tell how tall you are, I would use one or the other of these rules; as each is divided into even inches, I could use any of these three I should prefer. I would say one boy is four feet two inches, another four feet nine inches and another five feet four inches, and so on according to the height of each person. We speak of this kind of measure as feet and inches. When it is used in measuring cloth, or other goods in a store, we speak of it as yards and parts of a yard. Then there are also other forms of measures, dry measure--quarts, pecks, bushels; and liquid measure--quarts, gallons and barrels. There is also a standard of weight--ounces, pounds and tons.
