Grasshopper Control oc 
Af W *w U ?° n Hl i S f f rm tHat the firSt demonstra -tions were conducted. 
t that time the hoppers were so numerous that a complete devas¬ 
tation of his crop was threatened. On checking over the results, 
three weeks later, one had to go, on an average, from 30 to 60 
steps before seeing a live grasshopper. 
In a great many places in the valley, numerous pigs are raised 
and pastured on alfalfa, and in most cases these fields were badly 
infested with grasshoppers. The owners of such fields were skep- 
tical about treating these fields for fear of poisoning their stock. 
lie some were not afraid of the Paris green directly, they were 
afraid that the hogs would eat the dead hoppers and thus be pois¬ 
oned. However, this point was cleared by Tiner, Drake, Arthur 
and Davis. Mr. Tiner had 28 spring pigs (Figs. 2 and 3) feed¬ 
ing at all times on the poisoned area, and the other men had 135 
,-43, and 175 pigs, respectively, of all ages, feeding upon grass¬ 
hopper-infested pastures that had been sown with Paris green 
bran mash, and one pig died. The owner thought this pig was 
poisoned, but it is possible that one pig out of 553 could* have 
died from some other cause than poisoning from the bran mash. 
In the counties of Rio Grande and Saguache, San Luis Val- 
ley, practically all the infested land, where control work was con¬ 
ducted, was organized into pest districts and the farmers used 
the Paris green bran mash according to the Kansas formula. All 
materials used were purchased in large quantities and distributed 
from a central point, ready mixed. 
In Rio Grande County, Mr. Fuller, a druggist of Monte Vista, 
furnished most of the poison used. This he mixed, upon appli¬ 
cation, and furnished to the farmers at a less rate than they could 
buy the materials at retail and do the mixing themselves. During 
the campaign he mixed and distributed : 
6,550 pounds of Paris green 
38 tons of bran 
41 cases of lemons 
1,380 gallons of syrup 
However, this does not represent all the materials used in 
the two pest districts in his county, as a large quantity of Paris 
green was obtained from the sugar factory and some from Center. 
In Saguache County, Mr. Sumpter, a druggist, furnished and 
mixed the materials used. An exact account of the amounts used 
was not kept, but it is safe to estimate that the quantity used was 
at least half that of Rio Grande Countty. A machine mixer, (Fig. 
8) was used by Mr. Sumpter which greatly lessened the work of
