World Without Stars, VI.
Day is "days" long, therefore the (very dark) night will be equally long so the men work hard to make camp.
Colours are difficult to identify in the dim light.
As usual on terrestroid planets in Poul Anderson's works, there is an equivalent of grass:
"...those tussocky growths which seemed to correspond to grass..." (p. 36)
There are no seasons because there is little axial tilt. Also:
"Photosynthesis under a red dwarf star can't use chlorophyll." (ibid.)
Scientific knowledge is crucial in sf.
Local wild life lacks certain amino acids, vitamins etc but the men eat packaged supplies, then get their food plant working. This is described in detail and we will return to it this evening when I have returned from a day trip to Blackpool. Chapter V has presented a plausible explanation of why the food plant at least had survived the wreck of the ship and its two ferries. Poul Anderson sets his characters up for several years on this planet.
