er, side by
side, to make up the length of one inch. Like all other plants they
require food, and they find this in the dough they are placed in. You
know that all things are made up of atoms of chemical substances so
wonderfully blended together that only the chemist can separate them,
and when he has separated them they appear very different. Well, in
flour there are certain things so blended, and the yeast-plant takes
one kind of substance as food, and in doing so sets free another
substance called carbonic acid gas. This gas bubbles up and makes the
heavy dough spongy and light. If it were not for these tiny bubbles of
gas your bread would be as heavy and close as suet pudding. This is
the reason why yeast is put into dough for making bread or cake. One
of the most remarkable things about this yeast is, that when it gets
into any substance that contains its food, it at once begins to give
off buds, which, in a few moments, become full-sized and break away.
So rapid is this increase, that if a single yeast-plant were to be put
into a great mass of dough it would very quickly leaven the whole
mass.

And so it is with the love of God. When once it gets into our hearts
it will keep on growing until all our life is filled with it, and we
try in all things to please Him.

SEEKING FOR HIDDEN TREASURE.

The people of Canaan, both in ancient and modern days, have made a
practice of hiding their treasures. This they have done to secure them
in times of danger. When invaders flocked into the land, the people
buried their gold and jewels, and fled. And often they died, or were
overtaken by their enemies and killed, so that they were unable to
return and regain their buried riches. Earthquakes also have taken
place, destroying towns and villages, and burying all the riches in
them beneath their ruins. Thus there is much hidden treasure in
Canaan, and numbers of the inhabitants spend their time seeking
diligently and anxiously for it.

Our artist shows us a man who is thus seeking. He has heard that in
old times a great treasure was hidden in a particular field. So he
digs away patiently in various places until, at last, he finds out
that what he heard is quite true. He is sure the treasure is _there_;
and his desire is to become possessed of the field, so that he may
obtain the buried riches. He is willing to sell all that he has if by
so doing he may buy that field. So
