alfalfa and orchard had occurred I could learn of no loss. Caloptenus 
differentialis I found in some numbers, and there is little doubt that 
unless some effort is made this fall and next spring to destroy eggs and 
young they will multiply as in other localities, and probably by next 
season prove as destructive as in them. 
As this point carried me into the westernmost row of counties in the 
State, and there was no report of damage farther on, I determined to 
cross northward to the Missouri Pacific Road, in order to follow up some 
rumors regarding damage from grasshoppers at some points intervening, 
and which, from the descriptions given, seemed possibly to be due to 
Dissosteira longipennis. No point where serious loss occurred was found, 
however, and this species occurred but sparingly at points between 
Syracuse and Tribune, and occurred at Horace only in smail numbers, 
too few to cause any apprehension for the immediate future at least. 
Taking the Missouri Pacific, I passed through to Kansas City without 
finding any evidence of damage from grasshoppers, and as I could learn 
of no other localities in the State than in the three counties examined 
where such damage was reported, I returned to Ames, and will now pro- 
ceed to a detailed account of the territory examined, the species ob- 
served, and the special measures needed to meet the outbreak in this 
section. 
THE TERRITORY AFFECTED. 
The damaged territory is quite easily defined and might very prop- 
erly be said to coincide with the irrigated portion of the Arkansas 
Valley lying in Finney, Kearney, and Hamilton Counties in southwest 
Kansas. The entire irrigated district, however, is not equally injured 
and there are some fields much less damaged than others. The whole 
area covered extends with occasional breaks a distance of about fifty 
miles along the river and forms a strip from one to five miles wide but 
limited entirely to areas where irrigation has been practiced, and within 
this limit is dependent upon the kind of crops raised. 
The greater damage was observed at Garden City, though nearly as 
bad was seen at Lakin, and but little was found at Syracuse, corre- 
sponding as near as I could learn pretty closely with the length of 
time since alfalfa has been made a principal crop on the irrigated 
lands. 
THE CROPS AFFECTED. 
Alfalfa is the crop in which there is the most loss, but orchards are 
- suffering badly, and were they extensive throughout the district would 
very probably present the heavier loss. 
The alfaifa crop is a very profitable one and easily grown with irriga-_ 
tion and has been very extensively planted, the fields devoted to it 
covering many thousands of acres. 
The injury to this crop is of such a nature that I believe practical | 
remedies may be adopted, and, as will be stated later, active measures | 
| 
should be adopted this fall and next spring.
