the rust disease originate as a rule near the gulf and work north at about the same rate as the season, and there is no possible way of protecting the wheat from these spore attacks. These spores travel in the atmosphere four or five miles an hour against prevailing air currents, and the only way to offset their effects is to breed a plant that will sufficiently resist them. As there are all sorts of germ diseases against which the human body is immune only through the development of resistance, so in plant life we have to breed a type that will resist these attacks.
