272 THE FUR SEALS OF THE PRIIULOF ISLANDS. 



August Vi. — Seals are out in force on Tolstoi rookery. Fewer seals are on the 

 bauliiig grounds, as tlie bachelors are now distributed over the rookery. 



August K). — A pup taken from Speel, upon dissection, showed the foramen ovale 

 and the (Juctiin (tricriosns to be open. Tiiese ducts near the heart are usually closed 

 np alter birth in the animal world. The bulls have left the rookeries within a few- 

 days, making not lar from three months' shore duty without food or entering the 

 water. 



August 18. — It is reported that seals have not hauled on Otter Island for two 

 weeks. 



August 20. — Three seals were examined by Dr. White. In all cases the foramen 

 ovale and the ductm arteriosus were closed. They were found open only in the two 

 mouths' old pup from Si)eel. Microscopic examination revealed a probable ])arasite 

 to the Hat parasitic worm that iufests the intestines of the seal. The long, Hat worm 

 is found in the upper part of the bowels. The cylindrical worm, with pointed conical 

 ends, is only in the stomach, so far as observed.' 



August 'S2. — Tlie plateau of the Keef was quite uniformly covered with cows, pups, 

 and bachelors. The females are more silvery gray- in appearance than formerly. All 

 appear fat and healthy. 



August 2:>. — The seals were found hauled out in large numbers over and well 

 back from the rookeries. In a pup which was found dead on the rookery ground at 

 Lukanin tho J oraw en ovale was found open and the dnctus arteriosns was short, large, 

 and oi)en. This puj) was evidently newly born at the time of death, which must have 

 taken place ten days at least before this date. No bladder was found, but a large 

 duct passing from the umbilicus to the urinal vent. 



August 2(5. — Found a dead female seal 3 years old cast ujiou the rocks along 

 Speel. She was given to Dr. White for dissection. 



August 28. — A drive from Zoltoi for food yielded 20;5 seals.' Only 3 skins were 

 accepted; of these 2 were females accidently killed. 



August 29. — (Jows and i)ups are distributed quite numeronsly over Lukanin 

 rookery. Many line 5 year old males are to be seen in dillerent parts of the rookery. 



September .5.— The rookeries at Tolstoi, English Bay, and Southwest Bay seemed 

 to be in good condition for this season of the year. 



September 12. — The old bulls are all gone from Lukanin aiul Kitovi. A lew half 

 bulls still remain. Cows, pups, and bachelors are numerous, but not so many are on 

 shore as at my previous visit. Two female seals were found insensible under the blulf 

 at East Landing, where they had evidently fallen from the to]). 



September 23. — A favorite hauling ground for the pups is the shore line south of 

 the village, though unoccupied by any of the other classes of seals during tlie season. 

 The north side shore is also frequented by pui)S as far as the new warehouse.

-Due to tlie presenet^ of 2-year-olils and yearlings, the yoiiuijer seals coming in later and hvin'^ 

 lighter in color as a rule. 



'A disinssioii is noted between the Aleuts and the agent as to the age of the seals to bo killed 

 for food, the people ])rcfeiriug the smaller seals. The cnsti>ni had been to kill the larger ones. The 

 agent at this time, lio\vev<'r, apparently granted the reipiest to kill the smaller seals. Coinjilaiut was 

 urged against the distiirhance of the rookerii's in getting the specimens tor Dr. White. Thi- skins of 

 the smaller seals were naturally rejected and so wasted, while nothing is said of the disturbance 

 created by driving Reef Rookery throe times for food.
