having charge of such lane! and residing in the county. If the owner 

 he a non-resident of the state, or his residence be unknown, and he 

 have no known agent in the county, two weeks' pubhshed notice of 

 such order shall be given. 



"Sec. 7. Same — Failure to obey. If the order be not complied 

 with, the board shall cause the infested land to be plowed at the ex- 

 pense of the county. In case such plowing shall be of value in the 

 raising of a crop during the season immediately following, the per- 

 son so benefited shall be liable to the county for such value. When 

 the board is of the opinion that such liability exists, it shall deter- 

 mine the amount thereof, and its determination shall be prima facie 

 evidence of such value. It shall direct the auditor to demand payment 

 of the amount, and, if it be not paid upon demand, the county attorney 

 shall bring a civil action therefor in the name of the county." 



In concluding these remarks upon grasshoppers, it may be said : 

 There is no question but that plowing, particularly fall plowing, is the 

 best, cheapest and mose effective means in the hands of the farmer

for combating grasshoppers, yet farmers who are not planning to 

 plow for crop purposes are not always ready to go to this trouble 

 and expense until they see some actual damage done by these pests ; 

 a statement from an entomologist that certain stubble fields are riddled 

 with grasshopper eggs does not always influence the owner to take 

 prompt action, and the eggs are allowed to lie unmolested. It is not 

 until these hatch, and the young hoppers becoming quarter or half 

 grown seek to appease a ravenous appetite by inroads upon the grow- 

 ing grain, that the hitherto indififerent farmer realizes the fact that 

 something must be done immediately to prevent the loss of from fifty 

 to a hundred per cent of his crops. 



Even then it is not too late, if the farmer takes immediate action, 

 to overcome this small but powerful enemy to agriculture. He may, 

 if the hoppers are not too large to get out of the way of the plow, 

 say a half an inch or less, plow the infested land, working from its 

 edge towarfl the center. This turns most of the pests under, causing 

 their death.
