line in search of food thrown up by the sea, and pay particular attention 

 to seal rookeries, on the lookout for dead pups, which seem to be rel- 

 ished, and are dragged off for the young. 



"While the animals eat a great deal of grass and other land and 

 marine vegetation, it is evident that they cannot long survive on a diet 

 that does not include animal food. 



"The year 1890 may be considered the turning point in 

 Condidons ^^^ ^^^ °^^ ^^^^ Pribilof islands, which, of course, include 

 St. George. At that time, or soon after, a scarcity of foxes 

 was everywhere apparent, and the government agents in charge, 

 wrongly attributing the diminution to over-trapping, forbade all trap- 

 ping for three different winters in the early nineties, with the result 

 that the total catch for the seven years ending with 1897 was only 

 2,198. The real trouble was a shortage of substantial food, such as the 

 foxes had always been accustomed to, but this was not then under- 

 stood, or at least no steps were taken to supply the deficiency. 



"The slaughter of seals upon the ocean by pelagic hunters had so 

 decimated the seal herd, that, in 1890, only 6,139 were secured on St. 

 George island, instead of the regular quota of 25,000. In 1891, 1892 

 and 1893, owing to the modus vivendi, the number of seals killed on 

 this island was further reduced to 2,500. The sea-lion herd of the island 

 had likewise been greatly depleted, so that but few of those animals 

 were killed, and, consequently, there was little or none of that meat for 

 the foxes. 



"With the departure of the birds in the fall, the foxes, as usual, 

 scoured the beach for food, and that source proving insufficient, recourse 

 to the seal fields, where formerly they were sure of something when 

 driven to extremities, proved unavailing. The limited amount of seal 

 meat was soon cleaned up. After that, there was nothing for them 

 but starvation, and those that succumbed were quickly devoured by the 

 survivors. 



"Coincident with the regular feeding of foxes, the experi- 

 Trappi^g ment of catching them in small box traps was made. This 



was successful from the beginning, as the foxes did not 

 hesitate to enter for the bait, and sometimes two would get in before 

 the trap was sprung, although it was intended only for one. The foxes 

 came in such numbers that at least 50 box traps would be needed to 

 accommodate them. This suggested the erection of a house trap, and 

 accordingly a rough corral or house trap 8 by 14 feet was cons- 

 structed beside the coal house. Three or four seal carcasses were placed 

 in the trap for bait. The foxes entered with little hesitation and soon
