Life is also busy transporting and overturning the soils of earth, the stones, and the minerals. The miles-long drifts of sea kelp that float along our coasts may carry hundreds of tons of volcanic boulders held in their roots. I have followed these streams of life over 300 km, and seen them strand on granite beaches, throwing their boulders up on a 9,000 year old pile of basalt, all the hundreds of tons of which were carried there by kelp.
There are men who could neither be distressed nor won into a sacrifice of their duty; but this stern virtue is the growth of few soils; and in the main it will be found that a power over a man's support is a power over his will. If it were necessary to confirm so plain a truth by facts, examples would not be wanting, even in this country, of the intimidation or seduction of the Executive by the terrors or allurements of the pecuniary arrangements of the legislative body.Alexander Hamilton

...agronomy is this classification is divided into farm crops, crop pests, soils and fertilizers.
