SOME KESULTS OF STATION WORK. 63 



In its studies of citrus diseases the Florida station ascertained that 

 the fungus causing stem-end rot is present in the orchard during 

 practical!}^ the entire year., being found on dead and partially de- 

 cayed branches and twigs when the fruit is immature or not in the 

 groves. 



Eesults secured at the Idaho station showed a marked increase in 

 protein content of several varieties of wheat grown on land cropped 

 the previous year with potatoes, as compared with land in wheat the 

 year before. Irrigation investigations at that station showed that 

 wheat receiving from 18 to 20 inches of water during the season gave 

 a yield of over 50 per cent above wheat receiving no water. 



The soil investigations of the Illinois Station have turned the tide 

 of sentiment within the State from one of soil depletion to one of 

 soil upbuilding, as evidenced by the interest farmers and business 

 men are showing in the work, and in the application of the principles 

 advocated by the station by leading farmers everywhere throughout 

 the State. Among other results secured by the station during the 

 past year was the fact that within reasonable limits gain in weight 

 in growing animals is not in proportion to the feed consumed, and 

 that contagious abortion as known in this country is practically 

 identical with the disease as known in western Europe. 



The results of daily investigations at the Indiana station showed 

 that an excess of soft fats and large average fat globules in cream 

 materially increase the moisture absorbing and retaining property of 

 butter, while the acidity of cream, the size of butter granules, the 

 temperature of the wash water, the use of the dry or wet salting 

 method do not appreciably affect the moisture content of this product. 



The work in agronomy at the Kansas station brought out quite 

 clearly that the time and the method of seed-bed preparation for 

 wheat very materially influenced the yield, especially in a drj' season. 

 Land disked but not plowed produced 44- bushels of wheat per acre, 

 while land plowed at the right time, July 15, and at the right depth, 

 7 inches, gave a yield of 38^ bushels per acre. 



The Kentucky station established a practically accurate and reason- 

 ably rapid method for detecting Bacillus typhosus in water, having 

 used the same with success, and in one case obtaining a positive result 

 as early as the fourth day. 



In a study with a view to adapting the carbonation process of 

 clarifying cane juices, the Louisiana station discovered features in 

 regard to temperature and alkalinity which enabled it to remove ex- 

 perimentally a much greater percentage of impurities than has hereto- 

 fore been possible in sugarhouse practice. This station also dem- 

 onstrated that the fuel efficiency of bagasse can be materially in- 

 creased by utilizing the flue gases in drying this product, and showed
