yield of Early Baart has exceeded that of Pacific Bluestem by 3 
bushels, while the 3-year average yield exceeds that of the Blue- 
stem by 4.5 bushels per acre. 
Karun. — Karun (C. I. No. 2200-1) is a rather dwarf and early- 
maturing spring wheat, with beardless spikes (fig. 9, C), white, gla- 
brous glumes, and midsized, hard, amber-colored kernels. In yield 
it has ranked second among all the varieties of spring wheat grown 
at the Moro substation during- the 3-year period, 1913 to 1915, in- 
clusive. It has exceeded the Pacific Bluestem in that period by 
almost 5 bushels per acre. Karun resembles the Bluestem in its 
beardless, glabrous spikes, but differs particularly in its shorter straw 
and hard, amber-colored kernels. The original seed of Karun was

obtained in Persia by the United States Department of Agriculture 
in 1902. The variety is not grown commercially, but only on the 
experimental plats. 
Koola. — Koola (C. I. No. 2203-2) is a selection from a low-growing 
early variety of spring wheat, introduced into the United States from 
Arabia by the United States Department of Agriculture in 1902. It 
is a bearded variety (fig. 10, C), with white, glabrous glumes, and 
large, red, soft kernels. It has been tested on experiment farms for 
several years, but has never been distributed to growers. The Koola 
variety has given the highest average acre yield of all the spring 
wheats grown at the Eastern Oregon Dry-Farming Substation during 
the 3-year period, 1913 to 1915, inclusive. During that time it has 
outyielded the Pacific Bluestem by 6.3 bushels per acre. It also
