Some indication of the scope of the investigations may be obtained by summarizing these investigations by divisions. The number of investigations, however, does not necessarily indicate the investigational activities of a division, since the work devoted to different projects necessarily varies greatly: RESEARCH AND POPULARITY NOT ASSOCIATED The public has been very responsive to the Department's instructional work, made possible by the researches of my distinguished predecessors and their able associates. The man who has the ability to present to an audience in a clear and convincing manner the results of investigational work always obtains a satisfactory hearing. The man who understands the details of ordinary practice so as to relate the results of research to actual conditions is especially appreciated. Both types of men are very useful and very necessary to a successful Department of Agriculture. What all of us fail, however, sometimes to understand is that the men who actually extend the realm of knowledge and who, therefore, are in the last analysis the most useful servants of mankind perhaps rarely have any of these qualities. The men who made possible the building of the Panama Canal through their cloister-like researches on the life history of the yellow fever parasite may have been, from the standpoint of business, the most impracticable of men. The man who has done more than any other man in America to improve the dairy industry had this opportunity because the director of the station with which he was connected realized that research and popularity were not necessarily associated. The obvious difference in function between the men of research and the teacher or the men of direct public service creates a difficult administrative problem. The investigator who accomplishes most as an investigator must necessarily be much removed from the public mind. He may spend a lifetime on a problem of the greatest moment and finally leave its proper solution to others. The quicker rewards of other types of service often lure the ambitious man away from his task. Fortunately, however, as recently stated by Dr. Brooks, "no person attains to the highest joys who shirks difficulties." The Director of the station appreciates that if he fails to realize the fundamental requirements of men of research or fails to protect them in the quiet and orderly transaction of their tasks, he will fail in his full duty to the cause of agricultural progress in California.
