A few years ago the terms short-staple and Upland were practically interchangeable, but the great demand for long staple, chiefly from the manufacturers of thread and of pneumatic tire fabrics has led to a successful attempt to grow the longer fibers in the Upland districts, so that now more than a million bales annually are being produced in the Upland districts of cotton with a staple length of 1-1/8 inches and more. The world's total production of long staple is in the neighborhood of 2,250,000 bales. Egypt is the chief producer outside the United States, her product being approximately 1,000,000 bales of 500 pounds every year. Although the product is small, the best Sea Island produced in the United States grows upon the small islands off the coast of South Carolina. The long-staple Upland is grown chiefly in the Mississippi delta, where the product is called "Peeler," "benders," etc., though the percentage of long-staple produced elsewhere is steadily increasing. The success of certain Arizona growers in producing long-staple from Egyptian seed is being watched with great interest. More than 3,000 bales came from this source in 1916, the fiber averaging 1-1/2 inches in length. There has recently been developed there, the new and important Pima variety, which is superior to the native Egyptian cotton, being both longer and whiter, and the growers are now planting Pima almost exclusively. The following table, taken from the Encyclopedia Brittanica, gives the comparative length of staple of the more important varieties of cotton. The order in which they are given represents, roughly, their relative commercial value: _Length of Staple Sea Island Cotton in Inches_ Carolina Sea Island 1.8 Florida Sea Island 1.8 Georgia Sea Island 1.7 Barbados Sea Island 2.
