A hero is one who shows great courage and all miners could be considered as heroes. They wrote songs comparing their work to others but still stayed at the mines. This song tells their story.
SING HO! FOR ANTHRACITE

We dig by day and we dig by night,
For the iron ore and the anthracite-
For the ore so gray, and the coal so bright;
Sing ho, for the ore and the anthracite!

The sailor's life has its round of charms,
The storm and chase with their wild alarms;
And he sings as the boatswain pipes to arms,
"Ho! Ho! for the sea with its mystic charms."

The soldier fights for a scanty hire,
Yet pants for the strife and the battle's fire;
As he to the ramparts' heights aspires
Sings-"Ho! for the strife and the battle's fire!"

The farmer treads o'er his furrowed land,
And scatters seed with his careful hand,
And sings as he twists his shining hands,
"Ho! Ho! for hearty harvest hands."

The miner pants for no gory goal;
In vain to him may the battle roll;
Yet his manly heart and his fearless soul
Sing-"Ho! success to the gleaming coal."

We dig by day and we dig by night
For the iron ore and the anthracite-
For the ore so gray, and the coal so bright;
Sing ho! for the ore and the anthracite.
