THK STEALING OF COWS. 531 



There are 103 cows ou Lukauin rookery to-day. There were 74 yesterday and 52 

 the preceding day. This increase of cows is so slight as not to be recognizable except 

 by actual count. There is no bustle or confugion. The cows land siugly, quietly, and 

 are distributed over the entire length of the rookery. 



Under the cliffs at Lukanin there was yesterday a harem with a single cow in it, 

 to which a second cow was added. To-day one of these cows is held by a bull in the 

 rear. She has a long gash in her hip, showing that she has probably been taken by 

 force. Her pup is with her. 



Yesterday a neighboring harem, in which was a single cow, the earliest to arrive 

 on the rookery, received a second cow at 11.45. She has just had her pup. At 2 

 o'clock it seems not over 2 hours old. The cow which landed first is distinguished by 

 a scar behind her left front flipper. She does not look gravid. She may be a 2-year- 

 old, or she may have failed of impregnation last year for some cause. Unless other 

 accessions are made to the harem it will be possible to trace her further. She has 

 been out since the 12th of June. 



An instance of copulation was witnessed on Lukanin at 3.30 to-day. The harem 

 contained 5 cows. It was formed during the night of the 19th, 3 cows being 

 present in it at 8.30 o'clock on the morning of the 20th. It was not possible to 

 distinguish either the exact time of the arrival of the cow or the hour of the birth of 

 her pup, but it is reasonable to suppose that she was one of the original 3, and an 

 approximate estimate of the time between delivery and service can be reached. 



JUNE 24. 



I visited Kitovi and Lukanin rookeries in the morning. The Amphitheater has 

 its 46 bulls and now has 45 cows. One cow is in charge of a bull far in the rear of the 

 rookery. It is not likely that she was stolen, as bulls intervene between her position 

 and any harem. She must have wandered through thus far before any bull noticed her. 



Lukanin rookery had this morning 131 cows, all told. There may be a few more 

 cows lying among the rocks, but this enumeration as well as those preceding with 

 which it is compared are relatively correct. 



Directly under the cliff's are a number of harems which have grown to a 

 considerable size. One has 12, another 10, another 8, and still another 6 cows. With 

 the exception of one formed on the 12th instant these harems date no further back 

 than the 17th. They have grown by additions of 1, 2, and 3 cows a day since. At the 

 same time bulls with no cows alternate with these and there are single harems that 

 have received no accessions. The cows in landing seem to be attracted to the 

 crowded harems. Doubtless when the bulls in charge of them get all they can manage 

 the other harems will fill up. 



S'l'EALiwa OP cows. 



A young bull which ventured down one of the slides in Lukanin cliffs was 

 attacked, and endeavoring to make his way to the sea, all the bulls in the vicinity 

 were set in an uproar. He passed close to a harem of 6 cows. The bull in charge 

 was unusually valiant and followed him into the water. Perceiving this, one of the 

 bulls in tlie rear rushed into his harem and seized a cow, carrying her back about 20 

 feet. The bull set out in a rage to rescue her, but thought better of it and turned 

 back to make sure of his remaining cows. For an hour afterwards, however, he kept
