In February the soil refuses the plow, the sun refuses heat, the sky refuses rain, the seed refuses growth.

In May comes an opportune time when all forces conspire toward harvests; then the sun lends warmth, the clouds lend rain, the air lends ardor, the soil lends juices.

Then must the sower go forth and sow, for nature whispers that if he neglects June he will starve in January.
The planets also lend interpretation to this principle.

Years ago our nation sent astronomers to Africa to witness the transit of Venus.
Preparations began months beforehand.
