His hair was iron gray, almost silvery.
"An American Girl Abroad" by Adeline Trafton
Here was a great silvery iron-wood tree a-growing and spreading pleasant shade; and here we sat us down.
"The Little Red Foot" by Robert W. Chambers
What of the silence of the keys
And silvery hands? The iron sings…
Though bows lie broken on the strings,
The fly-wheels turn eternally…
"Fuel" by Lola Ridge
