The chain of rather unusual indirect effects referred to above, that this Rendition had upon certain phases of apri' practi-e, may be summed up briefly as follows: In the first pl&ce, horses, in general, are preferred to mules for use on the extensive lemon plantations in that section. Further, tte corrmon method of producing hay there for farm animals is by growing grains and rutting and curing same just before naturity. Oats thus handled makes good hay and is satisfactory for horses. But, as stated above, the growing of oats for this purpose had to be discontinued because of the unusually se- vere attacks of stem rust, and barley was substituted. It was found that the awns on the barley used for hay irritated the mouths of the horses to tlie extent of making them so sore that the horses did not do well. On the other hand, it was found that mules were not bothered in this way by tie barley hay. On account of this general situation the horses formerly owned on the large lemon ranch visited had been disposed of and mules substituted. The stem rust of oats was reported as serious locally in northeastern Pennsylvania. Here the severe attacks were associated va th aerial infe'^tions on the nomnion barberry. Local outbreaks were also reported from Vermont Both in North and South Dakota the more severe attacks were in the eastern sections of those Pig. 17.
