 the (liseoverv and disseniinatirtn of just tliis sort of infonna- 

 lioii. If we are not "getting" our moneys wortli," it is our 

 own fault. ( )ue trutli witli reii^ai'd to an insect wliieli causes 

 disease or levies a tax of often hundreds of millions of dolhirs 

 on some staple crop may he worth the entiri' annual cost of 

 the seientilie tlepartments of the government, as soon as the 

 knowledge is put to use. 



With hundreds of ex[)erts working at these problems, knowl- 

 edge is growing so fast that statements are likely to he super- 

 seded before thi' ink of a 1)ook is dry. In order to keep up to 

 date, every biological laboratory should have available for all 

 students two important publieations, the MontJily Lid of Pnl>- 

 Jirations and the Ejyeriment Station Record^ both issued bv 

 the I'nited States Department of Agrieulture. These ^^ ill 

 keep the student informed of every advanee in our knowledge 

 of insects, as well as of a great many other matters of interest. 



]\Iake a list of the most important insects of the neighbor- 

 hood, or those about which vou wish to learn, and follow them 

 through the indexes of the U.qyerime^it Station Reconl. Send 

 to your State Experiment Stati(^n or to Washington for the 

 bulletins you need, and, after studyino- them and collectinu" 

 and observing your specimens in the Held, mounting them so 

 that they will tell as com[)lete a story as possible, be ready to 

 report your results to the class. 



Working independently and without consultation, let each 

 member of the class prepare ;i list of the insects which Ik^ tlu'n]^s 

 every member of the conumuiity ought to know in order to 

 prevent annoyance, s})read of disease, damage to household 

 goods, stock or cro[)s. 'I'his should be done after woi'king 

 through the la])oratory types given in Chapters X-XIII, read- 

 ing bulletins and books assigned, and studying the lists given 

 below. After comparing and discussing individual lists, pre- 

 pare a class list which shall include the most important local
