The friends have gone home far up the valley 
of that river into whose estuary 
the man from England sailed in his own age 
in time to catch sight of the late forests 
furring in black the remotest edges 
of the majestic water always it 
appeared to me that he arrived just as 
an evening was beginning and toward the end 
of summer when the converging surface 
lay as a single vast mirror gazing 
upward into the pearl light that was 
already stained with the first saffron 
of sunset on which the high wavering trails 
of migrant birds flowed southward as though there were 
no end to them the wind had dropped and the tide 
and the current for a moment seemed to hang 
still in balance and the creaking and knocking 
of wood stopped all at once and the known voices 
died away and the smells and rocking 
and starvation of the voyage had become 
a sleep behind them as they lay becalmed 
on the reflection of their Half Moon 
while the sky blazed and then the tide lifted them 
up the dark passage they had no name for
