Khaki
ka'ke, a kind of light brown cotton cloth brought into public notice by its use for the uniforms of the British army in India. It is a dust colored sort of duck of great strength and durability, well adapted to the use of soldiers, especially in hot countries. It was worn by the British soldiers in the late South African War with the Boers. It was adopted by the United States army for use in the Spanish-American War and is now worn by the American soldier. Our government buys 5,000,000 yards of eight-ounce khaki a year for this purpose.
