Today I scraped some thin pieces from the bark and extracted some of the water from the surface with my pipette. I could see some of the cell structure of the wood, photograph the lichens in some detail and examine the living tissue taken from the bark including a rotifer, ciliates and smaller forms.
Wonderful what one can learn in the school of hard knocks !
