majority of the farmers attributed the small number of chinch bugs to the 

 good effects produced by the infection in the preceding year. That the un- 

 injurious numbers of chinch bugs in the counties named was not due to 

 meteorological causes is indicated by the fact that substantially the same 

 conditions of temperature and rainfall prevailed over the whole of eastern 

 Kansas up to the time of the writer's visit to Labette county. 



That the chinch-bug area had moved to the northeast is indicated by the 

 fact that a much greater number of applications for infection was received 

 from the northeastern counties in 1894 than in any preceding year. From 

 the following counties, in 1894, 1,123 applications for infection were received, 

 as compared with 462 applications in the year 1893: Johnson, Douglas, 

 Wyandotte, Leavenworth, Jefferson, Atchison, Doniphan, Brown, Pottawat- 

 omie, Nemaha, Marshall, and Washington. There was thus, in the year 

 1894, a decrease of 85 per cent, in the amount of infection sent to the 

 southern counties, and an increase of 140 per cent, in the amount sent to 

 the northern counties. 



3. — The Establishment of Substations. 



A large portion of the 38 substations located in Kansas were established 

 by the county commissioners of the counties in which they were located. 

 Among this class were stations in Allen, Barton, Dickinson, Lyon, Miami, 

 Mitchell, Osborne, Ottawa, Reno, Rush and Saline counties. 



No substation was allowed to be established unless the individual who 

 was to take charge of the station should first have visited the laboratory of 

 the central station for the purpose of obtaining instruction as to the identi- 

 fication of the true parasitic fungus as compared with other fungi readily 

 mistaken for the genuine parasite by an uninstructed observer, and also as 

 to the proper method of propagating the infection at the substation. 



4-. — Results of Experiments. 



It is estimated that each of the 50 substations supplied an average of 300 

 farmers with infection. This gives a total of more than 15,000 farmers sup- 

 plied with infection from the substations. If to these be added the number 

 supplied from the central station, it appears that upwards of 20,000 farmers 

 in the chinch-bug area were supplied with infection during the year 1894. 

 Reports have been received at the central station from upwards of 3,000 

 experimenters. About 55 per cent, of these reports are favorable, and in- 

 dicate an immense saving of crops consequent upon the use of the infection 

 sent out from the central station. The reports from the substations are vari- 

 able in their character. Inasmuch as the majority of these substations were 

 not established until late in the season, the dry weather and hot winds of 

 July and August seriously interfered with the success of the infection sent 

 out from such stations. The substations which were established early in the 

 season reported much more favorable results. The substations should be
