1912 University Of Illinois Urbana Circular 157 Soil Fertility Cyril G. Hopkins TF9
UNIVERSITY OF ILLINOIS
Agricultural Experiment Station
URBANA, MARCH, 1912
CIRCULAR NO. 157
SOIL FERTILITY*
ILLINOIS CONDITIONS, NEEDS, AND FUTURE PROSPECTS BY CYRIL G. HOPKINS
In the first chapter of the book of books it is written:
"And God said unto them, be fruitful, and multiply, and replenish the earth, and subdue it."
Of these four commandments we have obeyed the first two, but we have disobeyed in America, since 1607, the last two of these commandments.
When our own fathers were born (and many of them are still living), there were 17 million people in the United States, -in
1840; but the census of 1910 reveals a population of 92 millions in contiguous continental United States.
