Walt Whitman

Leaves of Grass. 34. Sands at Seventy. 36. The United States to Old World Critics

Here first the duties of to-day, the lessons of the concrete,
Wealth, order, travel, shelter, products, plenty;
As of the building of some varied, vast, perpetual edifice,
Whence to arise inevitable in time, the towering roofs, the lamps,
The solid-planted spires tall shooting to the stars.
