devoted mainly to grain growing. About 40 acres have now been 

 cleared and subdivided into about 200 plats, most of which are de- 

 voted to cereals and grasses. As in previous years, although most 

 of the cereals were killed by frost about the middle of August, a few 

 varieties matured their crops, from which it is hoped to breed earlier 

 and more hardy sorts. Fall plowing has been found essential for 

 crop production in this district, as it reduces very materially the 

 spring work and enables the crops to be sown earlier in the season. 



At Eampart grain groAving has also been the chief line of work. 

 Although this station is 3|° farther north than that at Copper Cen- 

 ter, winter wheat, winter rye, barley, and oats matured and all hardy 

 vegetables were successfully grown. 



Animal husbandry and dairying have been the main lines of work 

 at the Kenai Station. About 25 acres are under cultivation, most of 

 which are in grass or have been sown wdth oats for grain and hay. 

 Besides the Galloway cattle recently added, there is a small native 

 herd, making a total of IT head of cattle, all in good ■ condition. 

 Butter and cheese are being regularly produced and find a ready 

 market. 



The income of the stations during the past fiscal year was as 

 follows : 



United States annual appropriation 1 $1,500.00 



United States appropriation for live stock 3,000.00 



Farm products 350.70 



Total 18,350.70 



The Alaska stations are doing invaluable pioneer work, but their 

 usefulness could be much extended if additional funds were available. 

 The equipping and development of the experimental tract in the 

 Tanana Valle}'^ are urgently needed, since the results from the exist- 

 ing stations shoW' clearly that remarkable variations of climate 

 exist in different parts of the Territory and that the possibilities of 

 the great valleys can only be ascertained by a separate investigation 

 of each. The live-stock investigations should also be broadened to 

 include other breeds of cattle and some hardy breeds of sheep.

The Arizona Station is continuing its chemical studies on the ef-
