covered with long white hairs which are longer and more numerous 
toward the apex. The apex of the hull terminates in four conical 
pale-yellow teeth. The two prominent ones are located on the meson, 
are unequal in length, and are slightly bent ventrad. The other two 
are lateral and very short. 
The kernels (PI. IV, G and H) average in length 6.6 millimeters, 
in width 1.9 millimeters, and in thickness 2.8 millimeters. Viewed 
laterally, the dorsal and ventral margins are equally convex, and the 
distal end is obtuse. The opaque area when present is small and 
located on or near the dorsal margin. 
This variety matures in approximately 148 days and has produced 
an average acre yield of 2,086 pounds of paddy and 2.520 pounds of 
straw. Although it has the longest growing period of any of the 
varieties cultivated in this country, Blue Eose is preferred in the 
Southern States to the more productive Japanese varieties because 
of the general similarity of its kernels to those of the Honduras 
variety, which is so widely known and valued as a rice of excellent 
cooking quality. It lacks, however, the culinary properties of Hon- 
duras rice, but it produces a larger yield of head rice, upon which, 
unfortunately, the miller has placed too high a premium. Large 
mill yields are important, and varieties that can produce them are 
desirable, but a rice must also possess certain qualities for table use 
before it can become a highly marketable product for the occasional 
as well as the daily consumer. 
SHINRIKI. 
The principal introduction of the Shinriki variety was made from 
Japan in 1902 by Dr. S. A. Knapp, then an agricultural explorer of 
the United States Department of Agriculture. Prior to 1910 Shin- 
riki was probably the best known of the Japanese varieties grown in 
Louisiana and Texas. 
The slender wiry culms of this variety are light green and usually 
number 13 to the plant. Their average height, including the panicles, 
is 37 inches. The culm and sheath nodes are light green. The 
auricles are deciduous. The ligules are half an inch long. The leaf 
blades are very narrow, averaging three-eighths of an inch in width. 
The panicles have an average length of 8 inches, and each bears on 
an average 105 seeds. 
The seeds (PL IV, / and /) average 7.3 millimeters in length and 
3.6 millimeters in thickness. The glumes are pale yellow and have 
smooth margins. The hull, which loosely incloses the kernel, is light 
yellow and medium in thickness. Its surface has a burlaplike ap- 
pearance and is thinly covered with short white hairs, which are 
longer and more conspicuous toward the apex. The apex of the hull 
terminates in four conical light-green teeth. _ The two prominent 
ones are located on the meson and are unequal in length. The other 
two are lateral and very short. 
The kernels (PI. IV, K and L) average in length 5.4 millimeters, 
in width 2.1 millimeters, and in thickness 3.1 millimeters. Viewed 
laterally, the dorsal and ventral margins are equally convex, and the 
distal end is broadly obtuse. The opaque area is seldom conspicu- 
ous and when present is located on the dorsal margin.
