 Through the news service, which is conducted in co-operation with the 

 Extension Service, much information is furnished to newspapers and farm 

 journals regarding research work at the Station. Special articles on investi- 

 gational activities have appeared on the farm page of the Manchester Union, 

 in the Granite Monthly, and many other state publications in addition to those 

 outside New Hampshire. 



There have been few changes in personnel during the year. Mr. W. L. 

 Doran resigned as assistant botanist on April 15, 1923; and since the close of 

 the fiscal year the position has been taken by Dr. L. J. Klotz. Mr. C. P. 

 Spaeth, assistant chemist, was granted leave of absence for three months during 

 the year to pursue graduate study at the University of Pennsylvania. He 

 received the degree of Master of Science at the University of New Hampshire 

 in June. Mr. O. H. Pearson was appointed graduate assistant in the Horti-

Among the additions to equipment during the year were a new Pickel 

 extraction apparatus for making fat determinations in the feed inspection 

 work, an applanatic condenser, an oil emersion lens, and a Freas drying oven. 



The report on the work for the past year will be considered by projects 

 under the headings of the main types of funds. Adams Fund projects are

 tural phenomena, and hence are more technical in their nature. Projects 

 carried on under the Miscellaneous Fund are ones which through fees are either 

 in whole or in large part self-supporting.

Plant Metabolism Studies. 



The relation of plant metabolism to fruit production recently has received 

 a great deal of attention on the part of physiologists, biochemists, horticul- 

 turists and others interested in the study of plants. It has been shown that
