No More Learning

Time out of mind, this forge of ores;
Quarry of spars in mountain pores;
Old cradle, hunting-ground and bier
Of wolf and otter, bear and deer;
Well-built abode of many a race;
Tower of observance searching space;
Factory of river and of rain;
Link in the Alps' globe-girding chain;
By million changes skilled to tell
What in the Eternal standeth well,
And what obedient Nature can;--
Is this           talisman
Kindly to plant and blood and kind,
But speechless to the master's mind?
