understand and derive any benefit therefrom. The average farmer wants it in simple language, in primary lessons, so that he can grasp it and then put it to the test. They know nothing about the chemical nomenclature which they use in expounding things. It is all Latin to them. What the tillers of the soil want is information on these subjects, in plain Anglo-Saxon, and as plain as possible even then. It would be well for them to know what constitutes fertility, generally speaking. There are three constituent elements of fertility, namely: nitrogen, phosphate and potash. The first element, nitrogen, is what may be termed the motive power in the growing of the crops. There are inexhaustible supplies of this element in the atmosphere, and it only needs to be brought down. It costs you nothing. Help yourself. But it is a very costly element if you have to purchase it as a commercial commodity. Nitrogen, like the air we breathe, we can only use as we need it. It is a substance that cannot be cornered or there would have been trusts formed in the country, making every farmer in the land pay tribute to them. The second member is a mineral element, phosphate. The first condition necessary for the activity of a living organism is food. The food of plants and animals, in some respects, is different, but both are alike in requiring a supply of certain mineral substances for their nourishment. One of the most essential constituents of this mineral food is phosphoric acid. Without phosphates there can be neither growth nor life. This is why phosphates are so essential to worn-out land, especially where wheat has been grown continuously.
