We were t)l)liged to chrt)nicle last year a serious injury 

 from native CJrassho])pers in the Hill River District near AIc- 

 Intosh in I'olk county. 1 am pleased to say that this has not 

 been the case this year. Farmers m tliat vicinity have been 

 induced to plow their stubble fields and are thus annually 

 reducing the evil. In this connection I will state that the leg- 

 islature last winter, ever ready to promote the agricultural 

 interests of Minnesota, passed a "(irasshopper Law," which 

 makes it obligatory upon the owner or lessee of land wdiich 

 is declared, by an exi)ert, to be infested with Grass- 

 hopper eggs, to plow said land. This law has, I am confident, 

 already ])roven of \alue in keeping this dread pest within 

 bounds. Another law passed at the last session of the legis- 

 lature in the interests of horticulturists and nurserymen, as 

 well as for the benefit of their patrons and the state at large, 

 is known as the "Horticultural Inspection I^aw." Both of 

 these laws, while not as stringent as those which 

 exist in some states, and not as strict as we should 

 like to see them, are certainly steps in the right direction, and 

 can be amended from time to time if pulilic sentiment and 

 the interests of the state demand. Each law is given in full 

 in its proper ])lace in this report. 



( )n June 2T,d the following card was mailed quite gener- 

 ally to those counties of the state infested with Hessian Fly: 



This department of the Experiment Staiion is desirous of obtaining 

 all data possible upon this insect. The number of broods in Minnesota 

 is not known with certainty. The undersigned is doing field work on 

 this subject and would be very grateful to farmers if they would advise 

 him of the first appearance of any injury to wheat and send him speci- 

 mens. Specimens of the first appearing "flax seeds" on this year's wheat 

 are much desired. 



As intimated in that card, special work has been done 

 this year to determine the number of broods of Hessian Fly 

 in Minnesota. Contrary to the belief of my predecessor, Dr. 

 Lugger, who thought there was but one brood of this fly in 

 the state, we have, 1 think, put the occurrence of at least two 

 broods beyond question. This is fully discussed in the article 

 upon Hessian Fly in this volume.
