INTRODUCTION 



guidance, and this remark applies equally to the 

 penguins we found on the northern limits of the 

 pack-ice, some five hundred miles from the rookeries 

 to which they would repair the following year. 



The exact whereabouts of the Adelie penguins 

 during the winter months has been much discussed 

 by different writers. It is agreed that they repair 

 to the pack-ice, but our knowledge of the move- 

 ments of this pack is very vague at the present 

 time, and so unfortunately I can give but a rough 

 idea of the subject. 



I have collected and noted down the latest 

 evidence for the benefit of the zoologists of future 

 expeditions who may wish to investigate the matter 

 further, and 1 am indebted for nearly the whole of 

 it to Commander Harry L. Pennell, R.N., com- 

 mander of the Terra Nova from 1910 to 1913, 

 who kindly drew up for me Tables A and B (see 

 pp. 13 and 14). 



Probably the information which more nearly con- 

 cerns the penguins of Cape Adare rookery will be 

 found in Table A. The birds from Cape Crozier 

 and Cape Royds rookeries must have some four 

 hundred miles further to travel when they go North 

 in the autumn than those at Cape Adare.
