Figure 9,--Same specimen as in Fig, 8 with tag no. 10013 on left ear. The 
tag is of monel metal, weighs 1 gram, and is a standard poultry- 
wing band. 
The biologist and three native boys tagged 66 pups in an hour. One boy 
passed out the tags while the other two searched for pups among the boulders. 
One boy sat astride the pup's back and held its head down while the biologist 
kneeled and applied a tag to the right ear. The pup usually uttered a bleat 
when the tag penetrated its ear but showed no other sign of distress, We saw 
a tagged pup sleeping about 15 minutes after it had endured the operation. 
We pushed the sharp point of the tag downward through the ear about 
halfway between its base and tip. We had trouble in getting the tags to 
clinch, until the boy who passed them out learned to partly close each one 
with his fingers before he placed it in the pliers. The first few tags were 
oriented at right angles to the axis of the ear, Later, the tags were oriented 
lengthwise of the eer (fig. 9). 
Tags nos. 10,001 to 10,077 inclusive were applied, of which eleven 
failed to clinch and were discarded, 
Follow-up observations of the sea-lion rookery were made on two occasions.
