III. The climate and its influence upon the vegetation. 
Growth-forms. 
It is much to be regretted that I have had no other observations at my dis- 
posal than those published by the German Expedition. They are certainly very 
complete, but only extend over the one year 1882—83. Our observations from 
1902 only cover 13/, months and are of little importance. For several years there 
has been a small meteorological observatory at Pot Harbour, in connexion with 
the whaling station. Of course the observations carried out on that place, my own 
principal working-field, would have been of the greatest value and I am sorry that 
my efforts to get them have proved futile. 
Thus the observations are truly too few to permit of more detailed conclusions, 
but certainly sufficient to give an idea of the climate. I do not think that the year 
1882—83 was exceptional.
