Famous quotes containing the words samples, successive and/or independent:

    Good government cannot be found on the bargain-counter. We have seen samples of bargain-counter government in the past when low tax rates were secured by increasing the bonded debt for current expenses or refusing to keep our institutions up to the standard in repairs, extensions, equipment, and accommodations. I refuse, and the Republican Party refuses, to endorse that method of sham and shoddy economy.
    Calvin Coolidge (1872–1933)

    I lay awake awhile, watching the ascent of the sparks through the firs, and sometimes their descent in half-extinguished cinders on my blanket. They were as interesting as fireworks, going up in endless, successive crowds, each after an explosion, in an eager, serpentine course, some to five or six rods above the tree-tops before they went out.
    Henry David Thoreau (1817–1862)

    I have an intense personal interest in making the use of American capital in the development of China an instrument for the promotion of the welfare of China, and an increase in her material prosperity without entanglements or creating embarrassment affecting the growth of her independent political power, and the preservation of her territorial integrity.
    William Howard Taft (1857–1930)
