the agricultural possibilities of the Yuma Mesa with special refer- 

 ence to citrus culture. In connection with these investigations con- 

 siderable time has been spent in studying the climatology, to- 

 pography, and general features of the soil and in making detailed 

 descriptions of the fruit now being grown in the district and com- 

 paring it with that produced in other citrus regions. The entire 

 matter will be treated in greater detail and published as a joint 

 report by the committee. 



MISCELLANEOUS 



A number of trips were made during the past year to different 

 parts of the State in the interest of extension work in Horticulture. 

 The activities in this field, however, were confined largely to demon- 

 strations in fruit and vegetable conservation by drying, in which 

 the sulphuring process was used. 



Considerable time was given to the general supervision of the 

 work at the Tempe Date Orchard and at the Yuma Date Orchard 

 and Horticultural Station. 



Very valuable service was rendered the department during the 

 past year by the foremen of the different branch stations in their 

 careful execution of the work as outlined for them. The horticul- 

 tural work has been given further impetus in the recent appoint- 

 ment of Mr. A. F. Kinnison as Assistant Horticulturist.
