occur as a dominant social species in the upper part of the 

 sublittoral region? 



4. Please take particular note of the relation of the vege- 

 tation to the Inland-ice and Glaciers. Collect all 

 information bearing on the possibility of the existence of plant- 

 life in Greenland during the Glacial-Period. This includes not 

 only observations regarding the marks of the height and extent 

 of the ice-sheet in general, but also the occurrence of plants 

 at the present time — in the vicinity of the ice and even 

 upon the ice (ice covered with earth) ; and on the highest 

 mountain tops —, and also the climatic conditions луЫсЬ 

 predominate here. 



5. Do peat formations occur? Which are the peat-forming 

 plants in particular? The depth and quality of the peat should 

 be examined, and the circumstances (soil or climate) which 

 have caused the formation of peat. 



C. Biological questions. 



1. Is the vegetation snow-covered in лvinter? If vegetation occurs 

 in places bare of snow, what appearance has it? Please 

 collect specimens of portions which have survived the 

 winter, either fresh green or otherwise, if possible in spirit 

 or at any rate in a dried condition. What appearance has 

 the snow-covered vegetation which has lately been laid bare 

 or that Avhich is still lying under the snow? Specimens 

 should be collected in spirit, so as to ascertain amongst other 

 things whether the plants contain stored-up nourishment, and 

 whether there are any slight traces of flowers going to be 

 developed in the following year. 



2. As spring approaches, please note on the spot the first time 

 each species is observed in flower. It will be of great interest, 

 if it can be ascertained when spring generally and on an 

 average comes in the regions visited by the Expedition. Spring 

 phenomena in the animal kingdom should also be noted as 

 far as possible. 



3. In order to be able to examine the flowering and polli- 

 nation phenomena it is desirable to have the flowers put 

 in spirit while fresh. Observations regarding the visits of 

 insects are desirable; if possible the visiting insects should be 

 collected together whh the flowers. Fresh flowers should be
