More than this, I have proved, on more than one occasion, that a fungus disease which has proved destructive to a crop has originated in the first instance from spores produced on weeds growing on the borders of the field. A celebrated professor of agriculture, hailing from one of our universities, has pronounced the above statement to be a mycological myth, adding as a rider, that it was impractic- able to keep headlands, etc., clear of weeds. As to whether it is practicable to keep headlands clear, or even as to. 1-"k;. I.—Leaf mould infested with mycelium, turned out of a plant pot, in which a liegonia was planted. The mycelium attacked the root of the Begonia and killed it. Reduced. whether it is necessary to have uncultivated headlands at all, I leave for the practical farmer to decide. Some years ago, a batch of begonias that had been potted in leaf-mould went 'off in a mysterious manner. On investigation it was discovered that the leaf-mould in which the begonias were planted was overrun by a dense mass of white mycelium. As a rule leaf-mould contains mycelium, and in this particular instance the mycelium or spawn of some fungus proved predominant. This is only an isolated instance of the destructive work done by fungus mycelium present in leaf-mould. It can be prevented by intimately mixing a small amount of kainit with the leaf-mould some time before it is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Massee, George, 1850-1917.
