Wtisconn Dairymen's Association A LESSON IN FERTILITY: THE IMPORTANCE OF FEEDING MILLING BY-PRODUCTS IN WISCONSIN. Prof. W. A. Henry, Madison. The subject which I desire to bring to your attention at this time is one of deepest interest to every farmer in Wisconsin no matter what branch of the vocation he follows. Further than that, it is of state and national interest. The individual fanner should be anxious to at least maintain and, if possible, to increase the fertility of the soil on his farm. He should re- gard himself as a steward who has entrusted to him for a cer- tain period the care of a piece of mother earth.

Every crop grown on the land takes to itself from the soil cer- tain ingredients which come under the term "fertility." The farmers should know what these are and their value.

A large portion of the air surrounding the earth is made up of nitrogen, but unfortunately this nitrogen of the air is of no use directly to plants, for though bathing their leaves and passing into the soil to their roots, nevertheless it usually is useless because it is in an uncombined form. A plant may suffer or die from want of nitrogen although nitrogen be all about it, much as a fish may die for want of air when taken from the water. The little air which water normally contains Si
