It is not an easy thing for an expert housewife, using the same formula, always to achieve the same happy results in the white loaf.

He who plants a strawberry seed will find that the tiny seed will construct a plant, lay in the red tints according to rule and mix the flavor of the berry to a nicety that is the despair of the chef.

In the tropic forests there is a flower with a deep cup and the pollen at the bottom.

This pollen lies upon a little platter, and underneath the platter is that form of trap known as a figure four, much loved by boys.

When the bee, creeping down into the flower, touches that platter, it springs the trap that throws the fertilizing pollen upon the legs of the bee, to be conveyed to the next flower.
