Every successful demonstration farm was thus a center of influence, and the work was continued after Dr.Knapp's death under the charge of his son, Bradford Knapp.
The idea of the boys' corn club was vitalized in 1908 by Dr.Knapp, who planned to establish a corn club in every neighborhood, with county and state organizations.

Each boy was to cultivate a measured acre of land in corn, according to directions and keep a strict account of the cost.
The work of his father, or of a hired man, in ploughing the land must be charged against the plot at the market rate.

Manure, or fertilizer, and seed were likewise to be charged, but the main work of cultivation was to be done by the boy himself.

The crop was to be measured by two disinterested witnesses who should certify to the result.

Local pride was depended upon to furnish prizes for the county organization, but the most successful boys in every State were to be taken on a trip to Washington, there to shake hands with the Secretary of Agriculture and the President.
This appeal to the imagination of youth was a master touch.
Thousands of boys were interested and achieved results which were truly startling.
