number of harems, and apply it to those rookeries on which pups were not counted 

 but on which harems were counted. This completed census is as follows: 



Census, 1897. 



AUGUST 4. 



I made a count of the live pups on Ardigueii rookery this afternoon, finding 736 

 in all. These figures are very nearly correct, though it is difficult to get all the pups 

 because of their hiding under the rock piles. 



The count of this rookery last year made by Mr. Townsend and Mr. Crowley must 

 have fallen short of the actual conditions. The rookery has certainly thinned out, 

 and whereas 78 cows were above the mouth of the flat last year on the 14th of July, 

 this year not a cow or pup is visible on the flat and only 4 cows have been there at 

 any time during the season. The count of pups last year gave 650, which probably 

 represents not more than four-fifths of the pups present. Ten dead pups were found. 



Ten additional bulls were killed from Zoltoi sands for museum purposes. Mr. 

 Lucas killed a 2-year-old cow for dissection. He dissected a number of dead pups 

 from under the cliff at the northern end of Gorbatch and found Uncinaria present. A 

 little flat which last year's photograph shows to contain 17 dead pups has to-day only 

 6. It has not been occupied to any extent this season. A few pups pod there but no 

 cows were there in the season. 



A line of pups extends up to the very edge of the slope at some distance this side 

 of Old John's Eock. No cows are among them yet, but eventually the cows will 

 haul back. At this time last year the entire slope was filled with cows and pups.
