Some of the investigations of the Experiment Station which 

 are necessary for the sohition of the problems which the Sta-

 possible these are printed in other places, such as scientific 

 magazines published in this country and in Europe, and the 

 bulletins of the United States Department of Agriculture. 

 Something more than 200 printed pages were thus published in

 tentious papers that were printed in scientific periodicals, both
