ARIZONA. 97 



The work conducted with the Hatch and other funds was practi- 

 cally the same as in the previous year. A new feature Avas introduced 

 in the stud}^ of about 50 different varieties of beans native to Ari- 

 zona and Mexico and their use as a basis for breeding experiments. 

 The sheep-breeding work has brought the station flock up to more 

 than 200 animals and in general has shown good results from crossing 

 the Tunis sheep on native range stock. The department of animal 

 husbandry further studied oleander poisoning of stock, and deter- 

 mined the quantity of leaves of this plant required to kill stock. The 

 experiments were carried on with horses, mules, cows, and sheep. 



In connection with inspection work, the entomologist studied in- 

 sects and carried on cooperative spraying experiments. By means of 

 spraying, encouraged by the station in the apple-growing district of 

 eastern Arizona, the apple crop of the last season was saved. 



The agronomist made soil-moisture studies, determining the hygi'o- 

 scopic coefficients and the specific gravity of soils sampled to a depth 

 of 8 feet. Experiments with cotton were carried on at Phoenix and 

 Yuma. The tests at Yuma included Egyptian varieties. Native 

 beans were tested under dry- farming and irrigation methods. 



The botanist continued the range studies and the results obtained 

 are being prepared for publication. He also made studies of grasses 

 and forage plants with special reference to drought resistance, and 

 of forest trees, shrubs, and other plants adapted to different altitudes 

 within the Territory. 



Work in the date orchard was continued in cooperation with the 

 Bureau of Plant Industry. Great differences were found to exist 

 in the fruit of the different varieties. The tendency in some sorts 

 of drying up of the fruit in ripening was observed and the pos- 

 sible relation of methods of irrigation to this matter will be studied. 

 At Tempe there are now about 12 acres in date orchard, and dates 

 are also grown experimentally at Yuma. Olive culture and oil manu- 

 facture were studied by the horticultural department and a bulletin 

 was issued on the subject. It is concluded from this work that many 

 varieties of olives under Arizona conditions are well adapted to the 

 production of oil of very fine quality. 



Cooperative work, as in former years, was limited to range inves- 

 tigations and date culture in cooperation with the Bureau of Plant 

 Industry. Dry-farming investigations in southwestern Arizona were 

 prosecuted largely by means of funds donated by the El Paso & 

 Southwestern Railroad. Extension work was confined to farmers' 

 institutes supported by Territorial endowment and conducted 

 throughout the Territory. 



The appropriations by the Territorial legislature for the biennium 

 beginning July 1, 1909, were given in the report for the previous 

 year.
