crops. Ac^OiSdSi^^ty^OpJ thtf'ldtii of July I reached Syracuse, in 

 Hamilton county, and visited agricultural regions where grasshoppers 

 were at work. Upon the 20th and 21st I investigated affected fields 

 on the north, east and west of Garden City. I returned to my camp 

 upon the 22d. Being convinced that the damage by the grasshop- 

 pers was due to the prevalence of one species, I concluded to devote 

 my attention to the life-history and habits of this one. Accordingly, 

 observations were largely confined to this one species. The camp 

 was maintained in Edwards county until this form had reached the 

 adult stage, when, having already received reports of flights of grass- 

 hoppers on the western line of the state, and also of the prevalence 

 of grasshoppers in certain localities, I determined to make a survey 

 of all this region, to ascertain the numbers present and causes govern- 

 ing their presence, and also to visit the beekeepers of this region and 

 make such observations upon the actions of their bees toward alfalfa 

 as might seem practicable. 



Accordingly I left camp for Syracuse, and from Syracuse by team 

 drove north through Hamilton, Greeley and Wallace counties to Sharon 

 Springs; from Sharon Springs by rail to Oakley, where conditions 

 were noted, and from Oakley by slow train to Colby. Conditions 

 were again noted from Colby to Goodland. Reports had reached me 

 from this point of the prevalence of grasshoppers on the tracks. 

 Here, I made special examinations of the cow-catchers of engines 

 entering the roundhouse to ascertain the species of grasshoppers 

 caught along the track. Upon leaving Goodland I was given the op- 

 portunity to occupy a favorable position where flights of grasshop- 

 pers rising in front of the engine could be easily noted. This 

 observation was continued as far as Norton. At Norton, the agri- 

 cultural regions were visited, and the existing state of affairs noted. 

 This survey covered eleven of the twenty-four counties west of the 

 100th meridian, and two east of this meridian. 



The pages which follow contain the practical results of the obser- 

 vations made, extending over a period from July 5 to September 4, 

 as well as a fully illustrated summary of the experiments conducted 

 with the cooperation of the farmers during the past year. The hearty 

 manner with which all interested have entered into this work, and the 

 many opinions expressed concerning the favorable results, cause me 

 to believe that the work has not been in vain. Since my return 

 numerous inquiries have been received, examples of which are here- 

 with given : 



VERA, KAN., August 27, 1898. 



MY DEAR SIR: I read with much interest the article in the Kansas City Star 

 of August 19, 1898, about your experimenting with alfalfa by disk harrowing, 

 etc. I have quite an acreage of alfalfa that has not done very well this year ow- 

 ing to the wet weather, with perhaps other causes, and the crab-grass and sand-
