There are a few rices, whose height is less than 2/3 meter. The writer 
calls such rices “dwarf rice.” The dwarf rice, which has a low practical 
value is often grown for the sake of curiosity (Fig. 16). 
(6) Awned and awnless rice. 
This is one of the most notable differences in rice. The awn of rice 
is utterly useless to man and it gives a very disagreeable feeling to the 
workman when it comes in contact with him. The farmer therefore 
prefers awnless varieties, unless he has some special awned varieties, the 
valuable properties of which cannot be found among the awnless stocks. 
In ancient times when little care was taken of crops the awn might have 
been of some use for the protection of the grain against birds and other 
animals, and in the natural state of the plant it might have been more 
useful for the protection or as a means of distribution, but it is quite use- 
less in the present conditions of agriculture. Thus most of the prevalent 
varieties in advanced centers of rice-culture are awnless. Sir GEORGE 
Warr observes that the general conclusion to be drawn from an analysis
