Yearbook of the United States Department of Agriculture, 1913, Washington,
Government Printing Office, 1914. Lyster H. Dewey, "Hemp" pp. 283-346.
Illustrated. One of the most thorough studies on the commercial,
agricultural, industrial uses of hemp, Cannabis sativa L., ever written.
Covers soil type, history, world production in 1913, development of better
varieties, uses of hemp for fiber, seed, and as a rotation crop easy on the
soil and resistant to pests and as a method to control weeds. Explains the
agronomy of hemp in many countries of the world in 1913. A classic.

U.S.D.A. Bulltein #404, Washington, Government Printing Office, 1916,
Lyster Dewey and Jason Merrill, "Hemp Hurds as Paper-Making Material."
Discusses the manufacture of paper from the inner portion of the hemp
stalk, the xylem fibers or hurds. Dewey and Merrill established that one
acre of hemp had the cellulose equivalent of 4.05 acres of trees on a
yearly sustainable basis. This bulletin of 25 pages was actually printed
on paper made from hemp hurds.

The Schlichten Papers, Don Wirtschafter, 1994, Athens, Ohio. Letters and
correspondence between George Schlichten, inventor of a new hemp fiber
decorticator, and representatives of the Scripps-Howard newspaper chain
considering the possibilities of hemp as a source for newsprint. Includes
patent office drawings and details of this important invention from 1917.

Kentucky Agricultural Experiment Station, Bulletin #221, June 27, 1919,
pp21-43, "Marketing Hemp," John R. Humphrey. Attempts to show the American
hemp producer how to more effectively market his product so as to compete
with foreign competition. Need for better quality and mechanization
discussed. Illustrated.

Plant Physiology, Vol 11, 1936, "Time Factor in Utilization of Mineral
Nutrients by Hemp," Sister Mary Etienne Tibeau, pp. 731-747. A nun from
Mount Mercy College in Cedar Rapids, Iowa, did extensive studies on the
proper mineral nutrients to add to hemp for maximum growth and production.

Proceedings--Soil Science Society of America, Black, C.A., Vessel. A.J.,
1944, "The Response of hemp to fertilizers in Iowa." pp.179-184. Shows
crop yields in Iowa during the governments emergency program to grow hemp
during World War II. One test plot had a yield of 21.2 tons per acre.
Nitrogen added at a rate of 100 pounds per acre increased hemp yields by
2.47 tons. Nitrogen also increased the number of female plants.

U.S.D.A. Bulltein #1935, Brittain B. Robinson, 1943, revised 1952, "Hemp."
Shows farmers how to plant, grow, harvest, and ret hemp. Given to American
farmers during World War II because our foreign sources of cordage fibers
were cut off by the Japanese. Re-issued in 1952 during the Korean War when
it was feared that our sources of foreign fibers might be cut off by the
Communist Chinese.

Iowa Academy of Sciences, Vol. 58, 1951, pp. 221-228, "Nutrition and
Aeration in relation to growth in Cannabis sativa," John R. Weber.

Botanical Gazette, "Photoperiodic Responses of Hemp," Vol. 116, Sept.
1954, pp. 14-29, Borthwick, H.A., Scully, N.J. Photoperiod investigations
were undertaken in order to improve methods of field production of hemp.

Fibres, Engineering and Chemistry, "Monoecious hemp breeding in the United
States."1956, Vol. 17, Feaster, C.V., pp.339-340. Monoecious hemp has the
advantage that all plants come to maturity at the same time.

A History of the Hemp Industry in Kentucky, 1951, James F. Hopkins,
University of Kentucky, Lexington. A very thorough book on hemp's history
in the number one hemp producing state. Sen. Henry Clay was one of the
largest hemp producers in America .

America, Russia, Hemp, and Napoleon," Alfred Crosby, 1965, reveals how
hemp was one of the main causes of the War of 1812 when Napoleon formed an
alliance with the czar of Russia which cut off Great Britain's access to
Russian hemp. At that time nearly all the marine hemp used in the world
came from Russia.

Pharmacological Reviews, Vol.23, No. 4, 1971, "Chemistry of Marihuana,"
Coy Waller. One of the first studies that clearly shows that hemp-type
marihuana grown for fiber is very low in THC, the psychoactive component
that gets people high. The drug-type marihuana is very high in THC. Also
the precursor agent Cannabidiol, CBD, which is not psychoactive, is very
high in fiber-type hemp but very low in drug-type. This is important as
CBD is known to block the effects of THC. This makes the hemp-type doubly
useless for drug effects.

Economic Botany, 29: April-June, 1975, pp. 153-163. "Seasonal
Fluctuations in Cannabinoid Content of Kansas Marijuana," R.P. Latta, and
B.J. Eaton. Wild 'marijuana' growing in Riley County Kansas was found to
be very low in THC content. The leaves and flowering tops averaged from
0.01-0.49% THC with a mean of 0.14% THC. CBD which blocks the psychoactive
effects of THC was as high as 1.7% (Average marijuana seized by law
enforcement agencies is about 3-3.5% THC.)

Economic Botany, 29: 1975, "The Evolution of Cannabinoid Phenotypes in
Cannabis," Ernest Small, H.D. Beckstead, and Allan Chan, pp. 219-232.
These researchers for the Canadian Department of Agriculture tested over
350 varieties of Cannabis in Ottawa, Ontario. They determined that there
were two basic types of Cannabis based on genetic characteristics: a
drug-type which originates in hot climates such as India and is high in THC
but low in CBD and a fiber-type hemp which originates in temperate climates
and is low in THC but high in CBD and is used industrially for fiber and
food. This awareness of the separateness of the two types has vast
agronomic potential. It means fiber hemp can be grown without the drug
effect of 'marijuana.'

Compte Rendu Academie Agriculture de France, "Apercu de la Production de
Chanvre en France," Fournier G., Paris M.R., Paris R.R., Vol. 62, 1976,
pp. 1262-1270. (French). History and current, (1976) production of hemp
(chanvre) in France. Reveals the unfortunate connection between hemp and
the drug Cannabis. Shows how fiber and seed hemp grown for industrial
purposes has no psychoactive effect. Gives current yields and shows where
hemp is grown in France. Interestingly hemp is used as a wind-break in the
hedgerows of the Rhone River valley. Used as fish bait. Various uses for
hemp in specialty papers.
