both a crop of millet and of bugs, but will be forced to sacrifice 
the former to kill the latter. Just before the millet becomes 
too hard for the insect, it should be cut and left upon the soil. 
The bugs remain uponit for some time before realizing the 
necessity of migrating, and this delay should be utilized to 
burn millet and bugs. 
Another point in the life-history of these bugs is their love 
for warmth and dryness, and consequently their selection of 
fields offering bo‘h. Chinch-bugs prefer sandy soil or poorly 
cultivated soil simply because in such fields the plants are sinall 
and of irregular growth, thus permitting the sun to strike the 
soil directly, it not being shaded by the foliage. Fields well 
covered with plants, and consequently soils well shaded, are 
not attractive to these insects. A good farmer will not utilize 
such soils, but will enrich the sandy soil to such an extent as 
to produce a strong and uniform stand of plants; nor will he 
cultivate poorly a good soil; neither will he bea robber of the 
soil by continuing to remove crops year after year without re- 
turning something to the soil in form of manure to keep up its 
fertility. A good farmer will escape many losses by insects 
and other pests where a poor farmer would suffer. Good farm- 
ing, and clean farming, should be the motto over every farmer’s 
door. Poor farming means also a rank growth of weeds, and 
mainly of the different species of pigeon grasses, which in 
themselves are a great attraction to chinch-bugs. 
Another point in favor of the good farmer, or of one who 
feeds the soil generously, is a return of the thankful soil in 
form of strong and vigorous plants; plants which can withstand 
the attacks of injurious insects much better than the weak 
plants growing on a starved soil. 
As long as it.is the aim of the farmer to grow upon the big- 
gest scale possible only one kind of crop, just that long noxious 
insects will be numerous, or even increase still more in numbers. 
The reason for this is so self-evident that it is not necessary to 
explain. If more diversified farming was the rule and not the 
exception, as itis at present, fields containing the same kinds of 
plants would be more or less widely separated by fields contain- 
ing other kinds of plants, and insects would not find it so con- 
venient to multiply without let or hindrance. Such fields of 
cereals, separated by other fields containing other crops, would
