REMEDIAL AND PREVENTIVE MEASURES. (><) 
be found equally practicable here, as also will the post holes for col 
lecting the chinch bugs. This method is merely cited in order to call 
attention to its possible use where the others are found impracticable. 
The plowing of furrow- has .been in vogue since the first writings oi 
Le Baron and the second report of Doctor Fitch, and may be utilized 
in other ways than those previously mentioned. A heavy log 
dragged hack and forth in this furrow will pulverize the soil in dry 
weather, and Forbes has recorded the fact that where this has a 
temperature of 1 lo to L16 F. it is fatal to the young bugs thai fall 
into the furrow, even if they an 4 not killed by the log. As L20 is 
not uncommon in an exposed furrow on a hot summer day, it will he 
observed that there may he eases where this method will he found 
very serviceable, and especially is this likely to prove true in a sandy 
-oil with a southern exposure. In sections of the country where 
irrigation is practiced these furrows may be flooded and in this way 
rendered -till more effective without the expenditure of either time 
of money to keep them in constant repair. Doctor Riley long- ago 
laid considerable stress on this measure, believing it of much value, 
especially in the arid regions of the far AYest. The same writer ad- 
vised the Hooding of infested fields, w T herever it could be done, for a 
day or so occasionally during the month of May. It is hardly prob- 
able, however, that this will often be found feasible except in rice 
Held-, where it is sometimes practiced. 
NECESSITY FOR PREVENTING CHINCH BUGS FROM BECOMING ESTABLISHED 
IN FIELDS OF WHEAT AND GRASS. 
In the foregoing it will be observed that prevention of migration 
has been the chief vnd in view either by destroying the chinch bugs 
in their hibernating quarters, and thus preventing the spring migra- 
tion to the breeding places, or by various traps and obstructions to 
prevent them from migrating from such places to others not already 
in tested. The great problem remaining to be solved is to prevent their 
bleeding in wheat fields at all. As has been shown, it is absolutely 
impossible, with our present inability to forecast the weather months 
in advance, to be able to foretell whether or not an outbreak of chinch 
bug- is likely to take place. There may be an abundance of bugs in 
the fall -enough to cause an outbreak over a wide section of coun- 
try -and these may winter oxer in sufficient numbers to cause some 
injury in spring, yet a few timely, drenching rains will outbalance all 
of the-«' factors, and our wisest prognostications fail of proving true. 
It i< this very factor of uncertainty that renders unlikely the success- 
ful carrying out. over any large area of country, of any protective 
measures where, as in this case, the benefit to be derived will only be 
realized nearly a year afterwards, if at all. The average farmer,
