Upcoming timber

It is said that it can be impossible to see the forest,
for just all the many trees blocking the view.
Vosges in november mood – evergreen, but most only at the top.
The fir trees grow up quickly, mostly use the most energy at the top.
But the green top have to lifted-up on perhaps of the two thirds from the down.
To reach the open air and the live-giving light from the sky.
