(sstiniation of the uincuut of 'sulphuring' are unreliable. Methods for deter- 

 mining quantitatively the different forms in which sulphur is found in the 

 ' sulphured ' hop have been worked out." See also work previously noted

The administrative report notes, among other things, the inauguration during 

 1914 of a new special service for reporting the daily weather conditions over the 

 principal range region of the West as affecting the live stock interests; the 

 extension of snow surveys at high altitudes in some of the western States with 

 reference to water supply, and of the use of a new form of snow scale or stake 

 for this puri)0se; the extension of observations to secure better data for fore- 

 casting frosts in the citrus districts and in the orchards of the Northwest; and 

 the improvement of the flood warning service.
