Geo. T. Fairchild Rural Wealth and Welfare: Economic Principles Illustrated and Applied in Farm Life

Law of diminishing returns.—In considering the value [pg 080] of farm products, it is necessary to notice a natural tendency in all products of the earth toward greater cost of effort in production. This is called the law of diminishing returns, and is illustrated in every industry where the accumulations of nature are depended upon for making labor effective. Hunting, fishing and mining afford familiar illustrations of more work of the same kind for equal product.

The law of diminishing returns is universal and applies to everything that possesses value." Professor Seager in his "Introduction to Economics" says, "After a certain point has been reached in the cultivation of an acre of land or exploitation of a mine increased applications of labor and capital yield less than proportionate returns in product, it being understood, of course, that no important change is made in the method of cultivation or exploitation."
