planting, hill luiits, and tuber unit increase. Mr. J. W. Weston and Mr. 

 J. E. Kotila co-operating in tlii's work. 



Another series wa^s devoted to sugar beets and the possibilities of seed 

 production. The sugar beets did not come through the winter very well, 

 only 15 to 30% surviving. 



Co-operative work was carried on with Professor J. A. Jeffrey on sandy 

 and mucky soils at Wetmore and Sene}^ respectively. There were also 

 co-operatiVe plots in the varions counties. In most cases the grasshoppers 

 and dry weather destroyed all possibilities of obtaining results. The few 

 cases which did come through showed results as indicated previously as 

 to varieties. 



The following work will largely constitute the work for this year, 1022. 



Series of the commercial oat varieties has been continued and 

 also the pedigreed oats with a few varieties added to the latter from some 

 of the northern stations. 



The commercial field pea plots are still being carried with a few va- 

 rieties added to this. 



The barlejr variety series is continued with a rate of seeding of both 

 oats and barley ranging from one and one-half bushels to four bushels 

 per acre. A small series of sjiring wlieat plots are also being grown. 



Tlie potato work will be continued as last year. A few varieties are 

 planted in a lai'ge increase field for the beginning of better strains for 

 distribution. Mr. Weston and Mr. Kotila co-operating in this work. 



The annual hay crop and sunflowers will be continued as of last year. 

 A little work with corn and soy beans is being done. A few earlier types 

 of corn are being grown in ear to row work. 



A new project on the testing of I^ed Clover was begun. There being 

 twenty-seven strains, obtained from some of the states and a few from 

 Foreign countries. 



Sugar beets will be continued to see what can be done in the produc- 

 tion of seed. This Avill be largely cultural work to maintain the plants 

 over winter. 



There is also at present about twenty acres of increase into barley, eight 

 acres of peas and two acres of oats, for distribution. 



Co-operative tests are being conducted in the various counties with oats, 

 barley, alfalfa and sweet clover; also the work is being continued with 

 Professor J. A. Jeffrey at Wetmore on the Sandy area and at Seney on 

 the Muck swamp area.

 Dear Mr. McMillan : 



Report of the potato disease investigations carried on at this Station 

 in ico-operation with the Botanical Section of the College for the year 

 ending June 30, 1922, is hereto appended. 



Weather conditions during the 1921 season were not favorable to the 

 potato disease in general. Owing to the dry hot weather which prevailed 

 during the early pnvt of the summer, Blackleg was of \evy minor import- 

 ance and no cases of Late Blight, which is also associated with cold wet
