fodder varieties rake good ensilage for large livestock; (6) the 
f lowers are attractive to bees, vhich help to pollinate then; 
(7) the stalks, leaves and inflorescences when threshed are used 
by the peasants as fuel; the ash is a good fertilizer, rich in 
potash; (8) finally, the crop plays an important part in the rotation. 
Information is given on the production of sunflower in the 
U. S. S. R. , Rumania, Bulgaria where the Office for the Purchase of 
Cereals regulated the price of the seed in 1934, Czechoslovakia, 
Yugoslavia, and Argentina. 
Tables give world area and production of sunflower by countries 
average 1909/13 and 1924/28 and annually 1929-1936; and export and 
import of sunflower seed by countries 1929-1937.

An account of the chemistry of the sunflower plant "dealing 
chiefly with composition as related to the stage of growth... The 
sunflower crop in Canada is grown almost exclusively for the silo; 
there is nc extensive cultivation of it for seed."

The author discusses briefly the cultivation of sunflower in the 
United States as a silage crop and as a seed crop. Under the head- 
ing of production, chief demand, and prices of sunflower seed he 
notes that "approximately 95 j)ercent of the sunflower seed produced' 
in the United States is grown in Missouri, Illinois, and California... 
The largest crops on record (since 1919) were harvested in 1928 and 
1929, the production in each of those years amounting to about 
16,000,000 pounds... Up to 1927 the domestic production of sunflo\?er 
seed was usually insufficient to meet the demand, hence much seed • 
was imported. Prior to the First World War Russia contributed the 
largest imports, but since then Argentina, Manchuria, Rumania, 
Hungary, Bulgaria and other countries have been the chief sources, 
although during the past two years the quantity of sunflower seed 
imported has been small. Imports during the 10-year period, 1930- 
39, averaged 334,152 pounds. The largest quantity ever imported 
in any year was 5,677,525 pounds, which occurred in 1923. Since 
1922 there has been a duty of 2 cents a pound on sunflower seed. 
"The principal demand for sunflower seed in the United States is 
as an ingredient of scratch feeds for poultry. A small percentage
