Retracing our steps to the rotunda, we turn westward through the main hall of the Congressional Library to the lofty colonnade outside, from whose balcony we look down upon the view which Humbolt declared to be the most beautiful of its type in the whole world. Directly below us, past the western terrace of the Capitol, with its open basin full of gold fishes flashing in the sun, stretch the Capitol grounds. Many varieties of trees already grown to forest hight spread their interlacing roof of cool, green shadow over the malachite sward below. Beds of flowers set in the grass, from the early March crocuses to the November blooming roses, make the grounds fragrant and precious with their presence. Here the dandelion spreads its cloth of gold in early May. Here the chrysanthemums fringe the snow with pallid gold in white December. Now the fountains are lapsing in dreamy tune through the long June hours, and the seats under the trees are filled with visitors. Nurses with children in their arms, old men and women leaning on their staffs, lovers “billing and cooing” through the long twilight and starlight seasons. Beyond spreads the city, every ugly outline hidden and lost in a waving sea of greenery rippling and tossing above it. The great avenues run and radiate in all directions. Pennsylvania Avenue stretches straight on between its border of shade trees to its acropolis one mile distant, the great Treasury gleaming in the sun, and the white chimneys of the Executive Mansion peering above the trees; and still on, till it joins the primitive streets of Georgetown. Massachusetts Avenue, broad, straight, magnificent, spans the city from end to end unbroken. Virginia Avenue to the left, goes on to meet Long Bridge, leading far into the Old Dominion. Directly in front stretches the public reservation yet to be made splendid as the Nation’s Boulevards, but already holding the Congressional gardens and conservatories, the unique towers, and picturesque grounds of the Smithsonian Institution, the broad flower-banded terraces of the Agricultural Department, and the incomplete Washington Monument. Beyond we see the wide Potomac, flecked all over with snowy sails, far down old Alexandria, dingy on its farther shore; opposite the Heights of Arlington, and amid its immemorial oaks; Arlington House with the stars and stripes floating free from its crowning summit.
