of more thorough knowledge regarding the food habits of our 

 birds has prompted the Entomologist to include Press Bulletin 

 No. 19. We have also included an article on the common Amer- 

 ican toad, which is, without doubt, one of the most useful factors 

 available for the farmer and gardener in keeping down injurious 

 insect pests upon his place. The useful habits of this little 

 animal are far too little known and appreciated, and instead of 

 its being an object of aversion or persecution, its presence in our 

 garden should be encouraged in every possible way. Since the 

 publication of the special report upon the Mediterranean Flour 

 Moth, further work has been done by the Entomologist with this 

 destructive pest, and the report as revised is included herewith. 



Carrying out the plan outlined in last year's report, we have 

 inaugurated a campaign against the destructive leaf hopper, and 

 results of the work are given in this volume. We have also found 

 the Plum Curculio attacking apples, in some orchards causing a 

 loss as high as ninety per cent of the crop, and, therefore, this 

 insect, which is commonly associated with the plum, has been 

 discussed in connection with its work on apples. 



The Cottony Maple Scale has been extremely abundant and 

 destructive this year, attacking our shade trees in the Twin Cities 

 and the suburbs, and in various towns throughout the state, and 

 in neighboring states. Directions are given herein for control- 

 ling this pest. 



So many letters are received, asking for suggestions for com- 

 bating certain common pests of the vegetable garden, such as 

 cabbage maggots, cut worms, cabbage butterflies and the like, 

 that the writer has thought it expedient to include herewith the 

 latest remedies for these various peSts which are so abundant 

 everywhere. The Entomologist's own experience in his flower 

 garden has suggested to him also the advisability of placing in the 

 report a short chapter of suggestions to those raising flowers, as 

 to the best way to control certain insect pests, which are apt to 

 be unwelcome visitors in the flower garden. 



Additions have been made to the museum collection of insects 

 during the year, and as this letter is dictated we have just received 

 two boxes of insects from Japan, sent by a friend there, who has 

 had our wants in view even in the midst of other ensrrossine: in-
