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 18S2 — 83. Our observations from 

 1902 only cover 1 3 / 4 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.
