TESTS OF BARLEY VARIETIES IN AMERICA 171 
office it had been obtained directly in 1905. This variety undoubt- 
edly came from the dry -hill region west of Lake Mariout, Egypt, 
where many variations were found and brought to America in 1923 
by the senior writer. Like Coast (C. I. No. 626) and Club Mariout 
(C. I. No. 261), this is a 6-rowed bearded barley which originated 
in northern Africa. It is easily distinguished from these types by 
its long-haired rachilla, shorter straw, etc. 
In a comparison of the California and Club Mariout at Aberdeen, 
Idaho, in 1921 it was found that the awns of the former emerged 
three days earlier than those of the latter. The density of California 
Mariout was 3.7 mm., as compared with 2.6 mm. for Club Mariout. 
(PL II, C and D.) The straw length of the first was only 55 cm., as 
compared with 76 cm. for the second. Both in appearance and field 
requirements these barleys are quite different. The California 
Mariout is drought resistant, early, and well adapted to the warmer, 
drier interior areas of California. It will outyield the Coast barleys 
in these limited areas, but the Coast types remain by far the more 
important commercially. 
CLUB MARIOUT (C. I. NO. 261) 
Club Mariout (C. I. No. 261) was imported into the United States 
from Cairo, Egypt, by the Office of Foreign Seed and Plant Intro- 
duction, United States Department of Agriculture. In a letter from 
the Traders and Growers Union, Cairo, Egypt, March 3, 1919, it is 
stated that the Mariout barley comes from the district west of Alex- 
andria, along the Mediterranean, where it was cultivated in Roman 
times. In 1923 the senior writer collected a large number of barleys 
in Egypt. From these samples it would appear that the Club Mariout 
came from east of the lake, while the California Mariout was culti- 
vated on the dry hills to the west of it. Club Mariout is a 6-rowed 
bearded variety having straw of medium length and a short compact 
spike. At Aberdeen, Idaho, in 1921 the average density of Club 
Mariout was 2.6 mm. This variety is adapted in general to the same 
conditions as the Coast barleys. It is outstanding in yield at Chico, 
Calif., Moro, Oreg., and Hays, Kans. At these places it produced 
the highest average yield of all barleys grov/n for the five years from 
1917 to 1921, inclusive. It is grown commercially in California, 
where the acreage is increasing, a large part of the crop being ex- 
ported to Europe for brewing. There is also a limited acreage in 
Oregon. In most other localities in the West it is surpassed by the 
Coast varieties. 
Club Mariout (C. I. No. 932) is a pedigreed selection of C. I. No. 
261 made in the cooperative breeding experiments conducted by the 
LTnited States Department of Agriculture and the Minnesota Agri- 
cultural Experiment Station at St. Paul, Minn. 
FLYNN (C. I. NO. 1311) 
Flynn (C. I. No. 1311) is a 6-rowed smooth-awned hybrid made in 
the cooperative breeding experiments conducted by the^ United 
States Department of Agriculture and the Minnesota Agricultm'al 
Experiment Station at St. Paul, Minn. It came from a cross, Club 
Mariout X Lion, and was first tested in the nursery at Moro, Oreg., 
in 1917, where it was selected from several hybrids of the same cross
