COL. VAN DUZEE: Gentlemen, I am going to side step this argument for I do not think it worth while taking up the time. We are here for other purposes. Personal experiences are not the general rule because each one's experience differs from that of others. We might all tell our personal experiences and after we were all through we would not have accomplished anything. I want to take you back to the point from which we started this, in order to know what we are talking about. To illustrate what I want to say to you, we can take the root pasture of a tree and analyze it in every possible way so as to bring to bear upon it the best judgment we have from all sources. The tree grown upon a hillside has a root pasture which is entirely different in many ways from the root pasture in the river bottoms. If we have a tree growing on a hillside in a soil that easily transmits moisture and it gives that tree constantly a stream of pure water going through its root system, and there happens to be enough fertility in that vicinity, that moisture is impregnated with plant food, and the tree will get all it wants. You can't speak in the same breath of the tree growing in the river bottoms whose entire root pasture is entirely different. The root pasture may become contaminated by various things which may cause, so to speak, ptomaine poison. Therefore I say that every locality, every soil, every climatic condition, every variety of tree must be taken as individual. What would be good for an apple orchard in Virginia might be fatal to an apple orchard immediately south of Lake Brie in Ohio. The use of commercial fertilizer that would be good in one locality would be bad in another. Therefore I disapprove of this kind of a discussion, because we are not speaking to a definite point. I want to bring your minds to this point, that every individual tree and its locality, and the man that is responsible for its welfare, must be analyzed before you can speak intelligently about what must be done.
