one which offers every hope for successful work, if the residents of the 
affected localities can but be induced to make a Little effort at the 
proper time. 
The means which appear tome from inspection of the ground to prom- 
ise most successful results would be as follows: 
(1) To thoroughly break up the surface of the ground in and along 
the ditches before winter by harrowing thoroughly, cultivating or shal- 
low plowing, thus exposing the eggs to winter weather and natural 
enemies. 
(2) Wherever practicable, to flood the ground for a day or two at the 
time young locusts are hatching. I was told that the young hoppers 
were entirely unaffected by water, as they would crawl up the alfalfa 
stems and escape, and it is probable that sufficient flooding to accom- 
plish much good in this region is out of the question. My only hope in 
this line would be in watching carefully for the time of hatching, and 
using the water before the hoppers had obtained any growth, and if 
abundant along the ditches, putting a little kerosene on the water. 
(3) A use of the hopperdozer as early in the season as possible, when 
I believe the treatment of a strip 8 or 10 feet wide on each side of the 
ditches would destroy so large a part of their numbers as to prevent 
any serious damage. As I learned from a number of parties the hop- 
pers are scarcely half grown when the first crop is cut, it would seem 
that immediately after cutting the first crop would be the best time to 
use the hopperdozer. The hoppers would be large enough to jump 
readily and the dozers could be run very easily. It would be difficult 
to use them at any other time than directly after a crop was cut, as the 
dense growth of alfalfa would obstruct their movement. 
My strongest recommendation would be the urging of effort in break- 
ing up egg masses before winter, and then in case locusts still appear 
in any number in spring to resort to the dozers at first opportunity. I 
believe active use of these measures will be effectual, with a cost but 
trifling compared with the value of the crop to be saved. 
The information as to the species and the measures needed are cov- 
ered very fully in your Bulletin on Destructive Locusts,* and with some 
specific instruction regarding the treatment of ditches in this special 
locality would, I think, give the people of the district affected all the 
information necessary to protect themselves, and it would seem advisa- 
ble to send a number of copies of that bulletin to the postmasters at 
Garden City, Lakin, and Syracuse, to distribute to farmers, who would 
make use of them, as well as to those whose names I will furnish for 
this purpose.
