(As the references to Jabal, Jubal, and Tubal-cain are the first passages that have been given in the pupil’s book without being first presented in the class, it will be interesting to see how well the children have succeeded in getting at the facts.) What was our picture for this last week? How many people were there in it? What were they doing? What was the name of the man who is called “the father of all who play upon the harp and the organ”? So we found from our Book which tells us of the beginnings of things, that way back in the ages of long ago people learned how to make instruments of music and to play upon them. To-day we have wonderful instruments, great pipe organs, violins, pianos, cornets and other instruments of brass, and whenever we see these or hear their music we will remember that the Bible tells us that the one who first thought of making music in that way was named Jubal. When a man is taking care of large herds of cattle, what does he need to find for them? It is not easy to find pasture for a great many cattle, and it would be very tiresome and even impossible to go back every night to the home. It would not be comfortable to sleep on the ground with no protection from the rain or cold. Who was it that first thought of having a tent to live in, and carrying it with him wherever he went? So Jabal was the father of all such as take care of cattle and live in tents. Are there any people to-day who live in tents all their lives? (With a class of boys the reference to Tubal-cain could be introduced by asking for a penknife and getting the pupils to tell of the man who first thought of making tools and weapons out of metal. Ask if anything is being invented to-day. Lead the children to see that the possibilities of discovery and invention are by no means exhausted, and help them to realize the wisdom and love of God in giving to man power to think out such things.)
