80 NOTES ON THE AGRICULTURE, 



Mountain rice is cultivated in Manchuria in several 

 varieties often mixed. Two varieties of mountain rice belong 

 to the water type. Ten varieties of rice were observed in 

 the Kirin and Helungkiang province and ' they are as 

 follows : — 



1. — The white bearded red mountain rice (see PL III, 

 Fig. 1). In North Manchuria this variety has several local 

 forms : (a) with light hulls and red grains (b) with dark 

 brown hulls and red grains of 5.2 m.m. in length and 3 m.m. 

 in breadth (c) with light elongated hulls and with grains of 

 6 m.m. in length and 2.5 m.m. in breadth. The grains 

 covered with red, dark-red or greyish hulls. The hulled 

 grains are fragile with a farinaceous kernel. 



2. — The unbearded red mountain rice with broad grains 

 (see PL III, Fig. 6). A variety with hull of 7-8 m.m. in 

 length, 3-3.5 m.m. in breadth. The grains have a light 

 red cover. The endopleura is partly farinaceous. 



3. — The unbearded red mountain rice with narrow 

 grains (see PL III, Fig. 7). The hulls of this variety are of 

 8-8.5 m.m. in length and 3-3.2 m.m. in breadth. The grains 

 are of 5.5 m.m. in length and of 2.2 m.m. in breadth. 



4. — The black bearded red mountain rice with light hulls 

 (see PL III, Fig. 2). A variety with hulls of 6-7 m.m. in 

 length, and 2.5-3 m.m. in breadth. The grains are similar 

 in size to the white bearded grains. 



5. — The black bearded mountain rice with brown-red 

 grains (see PL III, Figs. 3 and 4). A variety with beards of 

 ^-5 cm. in length with hulls of a dark violet colour. One 

 form, the hulls of which are 8 m.m. in length and 3 m.m. in 

 breadth, the other the hulls of which are 7.5 m.m. in length 

 and 3.5 m.m. in breadth. The grains are of 6 m.m. in length 

 and 2.5 m.m. breadth. 



6. — The white bearded white mountain rice. — The hulls 

 are light and dark of 6.5 m.m. in length and 3 m.m. in 

 breadth, the beards of 1-5 cm. in length. The grains of 

 5-5.5 m.m. in length and 2.5-2.7 m.m. in breadth, the cover 

 being colourless. 



7. — The unbearded white mountain rice (see PL III, 

 Fig. 8). A variety with light yellow hulls of 7.5-8 m.m. in 

 length, 3.2 m.m. in breadth. The grains being 4.5-5.5 m.m. 

 in length and 2.2 m.m. in breadth, the cover is colourless. 

 The grains are more solid and transparent than other varieties 

 of the mountain rice. 



8. — The red bearded white water rice cultivated as 

 mountain rice (see PL III, Fig. 5). A variety with yellow- 

 rose and dark brown-red hulls and reddish scales. The hulls 

 are of 6.5-7 m.m. in length and 2.5-3 m.m. in breadth,
