bers of agriculture, associations for the production of beet sugar, 

 and so on, became interested in economic entomology and have coop- 

 erated with the State in the organization and support of control work. 

 Thus quite recently stations have been established in Poznan, in 

 Torun, and in Sarny. In the same way a special station for the study 

 of measures of protection of hops has been established in Luck, and 

 for sugar beets in Warsaw. There are now, therefore, 12 stations 

 for plant protection in Poland. In addition, the different agricul- 

 tural experiment stations scattered through the country include more 

 or less work on entomology. There are 27 such stations, and many of 

 these have recently added young entomologists or phytopathologists 

 to their staffs, largely for educational work. 



It is noted that there is a strong tendency to specialize in eco- 

 nomic entomology among the younger generation of workers. An 

 Association of Economic Entomologists (including several phyto- 

 pathologists) has been founded, and at the time of my last informa- 

 tion (June, 1929) had a membership of 50. There has been formed 

 an organization known as " The Union of Agricultural Experimental 

 Institutes of the Polish Republic." This Union is of an administra- 

 tive character and has a Section of Plant Protection which acts in a 

 way to coordinate the work of the different stations and research 

 organizations. It has begun this work by the publication of a series of 

 bulletins, of which one, entitled " Plant Diseases," has been issued. 



I was greatly interested in a visit I made to Poland in August, 

 1927. I was received with great courtesy by the officials of the Min- 

 istry of Agriculture, and took several automobile trips to different 

 parts of the country. I visited the important stations at Skierniewice 

 and Pulawy and met a number of the excellent workers. The chief 

 entomologist at Skierniewice at that time (and he still holds the post 

 January, 1930) was my old and distinguished friend Zygmunt 

 Mokrzecki whom I had met in 1907 in the Crimea. After the revolu- 

 tion in Russia Professor Mokrzecki escaped to Constantinople and 

 soon after became connected with imjwrtant work in Belgrade, later 

 going to Poland where he was given the post at Skierniewice. He 

 has established there a very competent service with several good 

 assistants, among them K. Strawinski who has published some very 

 good papers. At the time of my visit S. Nowicki was working with 

 him, but has since been transferred to another station. 



At Pulawy, S. Minkiewicz is in charge. Doctor Minkiewicz came 

 to the United States as a Rockefeller student in the early part of 

 1927, and remained in this country for many months. He was in 

 America when I visited Poland. He traveled extensively in the
