330 AGRICULTURAL APPROPRIATION BILL, 1924. 



Doctor Nelson. Yos, sir; they have a serial number. It is prov- 

 ing most interesting. We are getting very extraordinarilj- interesting 

 results, which will increase, of course, year by year, because of the 

 accumulation of the birds banded. 



We get t|uite as une.xjK'cted information as we did in regard to the 

 ducks batided near .Salt Lake, in Utah. Afterwards one of those 

 ducks was taken in central California, another one was taken over iu 

 Kansas, another one in Arizonsi, and another one in Alberta — at every 

 point of the compass from that center. The ducks went east and 

 west across the mountain, which was (juite surprising. That was 

 something we hud not suspected, and is very significant, because it 

 moans that these great marsh centers, such as the Bear River marsh, 

 at Salt Lake, form reservoii"s" from which ducks start and supply the 

 surrounding States in every direction. Before that we had always 

 supposed ducks flew north and south; we did not suppose they were 

 Hying at right angles to that course. 



Among the scientific researches are investigations in response to 

 inquiries from different governmental departments and from the 

 States, and we have the cooperation of a large number of people in 

 connection with that work. 



INVEBTIGATION8 RELATING TO FORAGE OF LARGE GAME ON N.\TIONAL FOKESTH. 



We are also investigating the relations of large game to forage on 

 the national forests in order to work out a system whereby a certain 

 amount of large game can be maintained without seriously interfering 

 with the grazing industry. At its last meeting the National Live 

 Stock Growers' Association passed a resolution asking that the Bio- 

 logical Survey and-wState officials handling matters of that kind insti- 

 tute an investigation in order to determine what can be done in the 

 matter of maintaining game in connection with the grazing industry. 

 We are carrying out that work as rapidly as we can. 



We have recently investigated the situation on the Kaibab Plateau, 

 in northern Arizona, which is a Federal game preserve and national 

 forest, where the deer have increased tremendously. There are now 

 not less than 20,000 doer there, and our men have made the recom- 

 mendation that about 2,000 bucks bo killed next fall, if possible, in 

 order to relieve the pressure. The deer are increasing to a point 

 where before long they will oat themselves out of forage. Thoy will 

 not only oliminato the live stock, but will eliminate themselves, and 

 st)mo ])ractical outlet must bo found to take care of the sui'])lus. 



Mr. Andeusox. We will now take up the next item, on page 210.

Doctor Nei,.son. The migratory bird treaty act. to enforce the nro- 

 toction of mi<^ratory birds. We \u\\v 2S fully paid, full-time wardens 

 and several Inmdred wardens on a nominal salary who <-an be used 

 whenever called (Mi. They received no pay e.xcopt $\ a year unless 

 actually employed in the service, in which case they receive J^.fU) a 

 <lay and their expenses, 'i'hese men are inaiidy deput v State game 

 wardens. We have the cordial cooperation of practically all the 

 State game services in the country, and in that way are able to accoui- 

 plish much mon' than would he otherwise possible.
