give warning of any existing or impending insect pests. 



Also, the investigations with sugar beets were extended to the 

 upper Gila under the personal care of Mr. Arney, of the Station. 

 The promise held out by the more favorable climatic records of 

 this district has, to an encouraging degree, been made good and a 

 continuance of operations is planned for next year. 



THE STATION STAFF. 



The changes in the staff during the year, while serious, have, 

 fortunately, not interfered with the usefulness of the Station. 

 Prof. J. W. Tourney, for nine years botanist of the Station, went 

 to the Division of Forestry, U. S. D. A., and from there to the 

 Yale Forest School. His thorough familiarity with the South- 

 west and his eminent ability to grasp and work out southwestern 

 problems, makes his loss a serious one. Dr. A. A. Tyler, for 

 one year associate botanist, has also accepted a connection with 

 Bellevue College, Nebraska. Dr. David Griffiths, for several 

 years special agent of the Division of Agrostology, U. S. D. A., 

 and having wide experience with western conditions, has assumed 

 the duties of botanist. 



Mark Walker Jr., for many years the efficient assistant 

 chemist of the Station, has been succeeded by W. W. Skinner, 

 M. S. , formerly first assistant chemist in the Maryland Station. 



The new department of animal husbandry was placed in 

 charge of Prof. Gordon H. True who came to the Station from the 

 dairy school of the Michigan Agricultural College. 



A new and useful feature of service established during the 

 year is the ' 'consulting' ' staff. This is composed of specialists in 

 subjects for which the Station cannot afford to employ the whole 

 time of expert investigators. For a moderate sum, however, it is 

 possible, as occasion may arise, to secure the services of a special- 

 ist for stated work. Technical correspondence also is turned over 

 to these gentlemen and they are expected to contribute to the pub- 

 lications of the Station as circumstances shall permit. 



Under this arrangement Prof. T. D. A. Cockerell of L,as 

 Vegas, New Mexico, has been appointed consulting entomologist 

 and Prof. S. M. Woodward, of Tucson, consulting meteorolo-
