and in grave danger of extermination adds to the urgency of 

 securing this collection without delay in order that the exact 

 status of our native species may be determined. We need a 

 complete collection of the young and adult of all the predatory 

 species of animals on which bounties are being paid, for refer- 

 ence in connection with the bounty system, chiefly with a view 

 to prevent payment of fraudulent claims. 



Thorough collections of game birds, mammals and fish 

 should also be made for reference in connection with the Fish 

 and Game Commission and its work of enforcing the laws. 



The object of the biological survey is not merely to accumu- 

 late a mass of mere remains of birds and animals, but to de- 

 termine the actual value of each species. The stomachs, as well 

 as the skins, of all birds and some of the mammals will be ex- 

 amined to determine the amount of good or harm they do. 



The results of a biological survey may be published in sev- 

 eral parts. One of these should treat of the mammals of the 

 state, with notes on their distribution, habits, and relation to 

 agriculture and man's uses in general. A second should deal 

 in the same manner with the birds known to occur in the state. 

 These should be followed by a full report on the life and crop 

 zones, with colored map showing the zones and their subdi- 

 visions, with as much detail as possible. Then profitable papers 

 could be written on, "The Breeding Grounds and Proper Protec- 

 tion of Game Birds in Oregon, " "Migration of Game and Other 

 Birds," "The Adequate Protection of Game Animals," "Food 

 Habits of Birds in Relation to Agriculture," "Methods of Ex- 

 terminating Injurious Animals," and many others of practical 

 value. 



These reports will be based chiefly upon the data gathered 

 by the field naturalists, and the specimens collected will serve 

 as vouchers for the accurate determination of species. Photo- 

 graphs should be made for illustrating the reports, and data 

 gathered for a large number of distribution . maps showing the 

 range of the more important species.
