Metadata[+] Show full item record
The data presented in the following pages is an attempt to establish standards of farm labor from observations of actual practices. It was collected from personal observations by the writer and Mr. L. E. DeVinna of Versailles, Missouri, under the supervision of the U. S. Department of Agriculture, during April, May and June of 1911 on farms in Saline County, Missouri. The farms in this county are practically level and free from stumps and stones. The formulas and the explanations of the same which are hereafter used are practically those furnished by the office of Farm Management in the letter of instruction to field men.
