The archipelago

The archipelago of Norway’s rocks,
now undisturbed, consists of blocks
which either show above the sea
or hide below, thus not to see.

For sailors those are surely stranger
and present the real danger.
For rocks are hard and don’t give in,
a fight with them you do not win.

That is why sea charts are at hand
to always see where you just stand.
You can’t neglect a single dot
when you plan the trip and plot.
