is to locate the eggs. Inspection should be made everywhere in the 
surface of the soil for the pods of eggs. When the infested areas 
have been located, they should be plowed deeply to bury the eggs, 
or disced or harrowed very thoroughly to break up the pods so that 
they will be exposed to the ravages of birds and other animals or 
dried out before they have time to develop. The earlier in the fall 
that this remedy can be applied the more satisfactory will be the 
results. It is better not to trust to one treatment, but to work over 
these places several times at short intervals. When young, or even 
when full grown, grasshoppers may be caught successfully in a hop¬ 
per pan. If this is set on wheels a few inches above the surface of 
the ground and driven over the alfalfa when that is a few inches 
high, great numbers may be caught. The best time to do this is in 
the early morning when the hoppers are on the tops of the stems 
and somewhat numbed with the cold. A third lemedy is that of 
arsenic-bran mash. This substance is made by mixing white arsenic 
with bran at the rate of one pound of arsenic to twenty of bran. 
After the substances are thoroughly mixed, add sufficient water to 
make a sticky, but not too sloppy material. Some add a little anise 
or syrup. The mixture should be scattered late in the afternoon or 
early in the morning so that the hoppers will get it before the hot 
sun has dried it up. 
In the Greeley experiments of 1910 the potatoes were sprayed 
with Bordeaux mixture to test the value of this substance as a re- 
pellant to grasshoppers. The results appeared to be favorable as to 
keeping off grasshoppers, but indecisive as to the prevention of flea 
beetle injuries to potato tubers. See Greeley Notes. 
TO SELL OR TO STORE POTATOES? 
A SYSTEM 
Selling from the Field. —To sell always from the field is as 
well as always to store. The wise grower will sell out of the field 
when the year’s production is greater than the aveiage yeaily con¬ 
sumption of three and one-half bushels per capita; and in such a 
year he will keep selling whenever any one will buy,' no matter What 
the market, because in such a season the price will show no geneial 
rise. It is folly to hold for a price for which the grower thinks 
he can afford to sell. . 
When to Hold. —The wise grower will hold, particularly fol¬ 
lowing a low price season, whenever the yield of the country is short 
of the average need, especially if quality be good and consumption 
likely to be large. 0
