570 THE FUR SEALS OF THE PEIBILOF ISLANDS. 



MR. LUCAS'S NOTES. 



I secure and dissect a dead pup on Lukanin rookery, finding it to be a clear case 

 of death from Uncinaria. (The results of dissections of dead pups from day to day 

 will be given under Mr. Lucas's discussion of "Causes of mortality.") 



MB. GREELEY'S NOTE ON NORTH ROOKERY. 



Cow died July 22, from unknown cause. Contained a fetus four or five months 

 along. She has probably had one pup, as she was in milk. It was probably a case of 

 superfetation. 



JULY 25. 



Mr. Lucas and I went to Lukanin rookery to get dead pups. We were not very 

 successful. The bulls and even the cows stand their ground very determinedly. Two 

 pups were secured, one of which, however, was too much decomposed for dissection. 



One pup picked up supposed to be dead was simply a prisoner attached by an 

 unusually strong umbilical cord to the placenta. There are a large number of dead 

 pups under the cliffs, which have been watched so constantly. Notwithstanding the 

 close watch, no deaths have been seen to result from trampling. One of the dead pups 

 is lying under the shelter of an overhanging rock — a position in which it could not 

 possibly have been trampled. A pod of pups lay about this rocli for some time. They 

 have now moved back. 



Messrs. Farmer and Warron arrived this evening on the Bush, reporting that Dr. 

 Jordan and the rest of the party will reach St. Paul on the 28th. The others have 

 stopped for a few days at St. George. 



A count of the liv« pups on Little East rookery of St. George was made to-day by 

 Dr. Jordan and 1,190 found. For these pups only 239 cows were present. 



JULY 26. 



MR. ADAMS'S NOTES. 



There were 463 cows on the Amphitheater in 53 harems. At the water's edge 

 under the cliffs of Lukanin a cow with her right eye torn out was seen. The wound 

 was fresh. 



One case of copulation was witnessed on Lukanin. Among the typical harems 

 which liave been counted daily is a new one formed since yesterday by a young gray 

 bull. It has 2 cows, one of which has nut yet had her pup. 



Four dead pups are lying in a group under the cliff at the southern side of the 

 Amphitheater. A number of small seals, presumably yearlings, are playing with the 

 pups at the water's edge. 



A drive was made this morning from Za[)adni and 514 killed; 491 large and 8;'0 

 small seals were turned back from the drive. One hundred skins averaged 8.ii3 

 pounds each. 



NOTED BY DR. JORDAN ON NORTH ROOKERY, ST. GEORGE. 



A small 2-year-old cow was seen among a pod of pups receiving no attention from 

 any bull. Pups are playing in little pools of water. Four fresh placentae were seen, 

 and 1 pup dragging a placenta.
