The campaign was taken up by County Agent Stanley V. 
Smith, thru the county commissioners, who furnished a given 
amount of Paris green to those who would apply it. This Paris 
green was distributed from various centers, consequently it had 
a wide distribution and was applied in many localities, but not 
in all cases where it should have been. 
One field on Orchard Mesa was very badly infested, there be¬ 
ing 7 acres of alfalfa which was almost entirely defoliated. The 
owner was distributing Paris green for the county and did not 
deem it necessary to apply it to his own land. Adjacent to this 
infested field were 15 acres of beans. The idea of the owner was 
to let the hoppers eat his alfalfa in order to save the beans. Had 
he applied the Paris green bran mash, he could have saved the 
entire crop. The yield would have been at least five tons, and hay 
was then selling at $13.00 per ton. This individual was paying a 
toll of at least $65.00 to the hoppers and not killing one, where he 
could have made an entire clean-up for $5.00, had he applied the 
bran mash. 
At the time of visiting the above place, the hoppers were leav¬ 
ing the defoliated alfalfa field and entering the bean patch around 
the edges. In all probability the entire bean crop was destroyed 
by the grasshoppers. 
In accordance with the pest law, several pest districts were 
formed thruout the State, three in the San Luis Valley, two in Rio 
Grande, one in Saguache County, one in the Fountain and Mesa 
district in El Paso County, and three were arranged for in Logan 
County, giving in the latter an almost continuous district thru the 
Platte Valley from Messex to Red Lion. This covers the princi¬ 
pal irrigated section of said county. 
On July 1, a second trip was made to the San Luis Valley at 
the request of the commissioners of Rio Grande County, to fur¬ 
ther the work commenced in the grasshopper investigations and 
assist Mr. W. E. Kistler, who was to be the pest inspector for the 
above mentioned districts. 
The first duty of the inspector was to check over various prev¬ 
iously poisoned places to determine the efifectiveness of the Paris 
green bran mash. The first forenoon, four farms were visited 
where there had been from 70 to 105 acres each, poisoned three 
weeks previous. The results were surprisingly good. In three 
out of the four farms visited, a complete eradication, instead of a 
control, had been effected. This was especially true on Mr. 
Tiner’s premises. Mr. Tiner was the first man in that section to 
take hold of the poison bait method for grasshopper control, and
