The annual yield of cuttings has varied from 2 to 5 tons per acre, which should give approximately 40 to 100 pounds of marketable camphor. At present the planting of small areas does not seem advisable, in view of the heavy outlay required for the machinery necessary to produce camphor gum at a profit. An area of less than 500 acres would probably not warrant the installation of the machinery necessary for the commercial production of camphor, and 1,000 acres or more will doubtless give a greater net return per acre. Although the crop is a low-priced one, under favorable conditions it is estimated that a fair return per acre may be expected, but the data so far accumulated are not sufficient to warrant specific statements concerning the profitableness of the industry. Camphor oil, or the oil from which camphor has been removed, is used in Japan for illuminating purposes, and as a solvent for resins in the manufacture of lacquer. It is used in Europe for its safrol content, and may probably be utilized for the same purpose in this country. There exists already in the American market a demand for the Japanese oil at prices ranging from 11 to 14 cents per pound. Camphor imports into the United States usually exceed 3,000,000 pounds annually; hence, it does not seem probable that there is any danger of overproduction in the Southern States. However, it is possible that at times camphor may be imported at a price so low as to render production in this country financially unprofitable. CANNABIS. The drug cannabis or Indian hemp (_Cannabis sativa_), consists of the dried flowering tops of the female plants. It grows well over a considerable portion of the United States, but the production of the active principle of this plant is believed to be favored by a warm climate. For drug purposes, therefore, this crop appears to be adapted to the Southern rather than to the Northern States. Cannabis is propagated from seeds, which should be planted in the spring as soon as conditions are suitable, in well-prepared sandy of clayey loam at a depth of about an inch in rows 5 or 6 feet apart. The seeds may be dropped every two or three inches in the row or planted in hills about a foot apart in the row, 6 to 10 seeds being dropped into each hill. Two or three pounds of seed per acre should give a good stand. About half the seeds will produce male plants, which must be removed before their flowers mature; otherwise, the female plants will set seed, thereby diminishing their value as a drug. The male plants can be recognized with certainty only by the presence of stamens in their flowers. Ordinary stable or barnyard manure plowed in deeply is better for use as a fertilizer than commercial preparations and may be safely applied at the rate of 20 tons per acre. However, good results may be obtained with commercial fertilizers, such as are used for truck crops and potatoes, when cultivated in between the rows at the rate of 500 or 600 pounds per acre.
