choicest green food. In two days the poison had done its work. In- 

 vestigations and reports from all over the county showed that from 

 60 to 70 per cent of the grasshoppers had been killed by the first appli- 

 cation. Counts made in alfalfa fields of average infestation, showed 

 from one hundred and fifty to two hundred and fifty dead grasshop- 

 pers per square foot. In many places under a single tree there was a 

 peck of dead hoppers, and along hedges the ground directly under the 

 hedge was completely covered, and in some places they were actually 

 piled up two and three deep. In other words, the results were far 

 better than anyone could have expected. 



The grasshopper control work did not stop with Ford County. It 

 was now an easy matter to organize, and eleven other western counties 

 followed the example of Ford Count}'^ in quick succession. In each of 

 these counties the ingredients were furnished by the county and the 

 same method of organization was used. Ihe results were equally as 

 good, and in some cases better. For instance, in Pawnee County 

 where one hundred and twelve tons of the poisoned bran mash were 

 distributed, fully 80 per cent of the grasshoppers were killed, and in 

 Ellis County where one hundred and sixty-eight tons were distributed, 

 one hundred and twenty tons of which were distributed in a single day, 

 almost 90 per cent of the grasshoppers were destroyed. 



The following report of the amount of poisoned bran mash used in 

 the grasshopper control work is taken from the reports of the county 

 officials:
