Hemp [ME., hemp, hemp]. The hemp-fiber is the pro- 

 duct of the Cannabis sativa, which is grown for textile 

 purposes chiefly in Russia and Italy, while the seed is 

 grown in India. It is a bast-fiber similar to that of 

 the flax-plant, but coarser and stronger, and of deeper 

 color, and less luster. It is used chiefly for the manu- 

 facture of ropes and cordage, and the fabric woven from 

 it, known as canvas, is used in sail-making. Hemp is 

 a mixture of cellulose and bastose. H., Manila, is a 

 tropical fiber obtained on the Philippine Islands from 

 the leaves of the wild plantain. It furnishes a very 

 superior rope-making fiber, because of its combined 

 lightness and strength, and the finer grades are used 

 for woven goods. The color is yellowish or white, 

 and the white variety has a fine silky luster. H., 

 Suron, is grown in India, and furnishes a fiber of 

 light-yellowish color. It resembles jute, although less 

 lustrous. It is well adapted for cordage and netting. 

 H., Sisal (or henequen), is derived from the fleshy 

 leaves of a species of agave grown in Yucatan and 

 the West Indies. It is used largely in the United 

 States as a substitute for jute in the manufacture of 

 bagging and for cordage, being stronger and lighter 

 than jute. See also Cannabis. H. -nettle. See 

 Galeopsis. H.-seed Calculus, a small rounded 

 urinary concretion composed of oxalate of lime. It 

 may vary in size from a pin's head to that of a hemp- 

 seed, and is smooth and dark-colored. H.-seed 

 Oil, oleum cannabis, is obtained from the seeds of 

 the Cannabis sativa or common hemp. It has a 

 mild odor, but mawkish taste, and greenish-yellow 

 color, turning brown with age. Its specific gravity 

 at 1 5 C. is .9276. It is freely soluble in boiling 

 alcohol, has weaker drying properties than linseed 

 oil, but is used in paint and varnish manufacture and 

 in making soft soaps.
