Treasure in the first usage means precious gems like gold or silver . In its second use, it means to value something.
Hope this helps. We could help more if I had the poem for sure posted here but this is the meaning from the poem I think you are talking about.
Have a great day!
The answer is Louis and Clark! 2 very brave men! O beautiful for spacious skies
For amber waves of grain
For purple mountain majesties
Above thy fruited plain
America, America
God shed his grace on thee
And crown thy good with brotherhood
From sea to shining sea
O beautiful for pilgrim feet
Whose stern, impassioned stress
A thoroughfare for freedom beat
Across the wilderness
America, America
God mend thine every flaw
Confirm thy soul in self control
Thy liberty in law
O beautiful for heroes proved
In liberating strife
Who more than self their country loved
And mercy more than life
America, America
May God thy gold refine
Till all success be nobleness
And every gain divine
O beautiful for patriot dream
That sees beyond the years
Thine alabaster cities gleam
Undimmed by human tears
America, America
God shed his grace on thee
And crown thy good with brotherhood
From sea to shining sea
O beautiful for spacious skies
For amber waves of grain
For purple mountain majesties
Above thy fruited plain
America, America
God shed his grace on thee
And crown thy good with brotherhood
From sea to shining sea
