Rice. By W. C. Stabbs {U.S.A. St. Bd. Louis. Bull. Q>\, illustrated). 

 — This bulletin deals in Part L with the preparation, cultivation, flooding, 

 and harvesting of Rice. 



Part IL contains special investigations made by Professor W. R. 

 Dodson on the noxious weeds found in the Rice-fields. 



I. Rice was first grown largely in Louisiana, directly after the war, on 

 the abandoned sugar plantations. 



All Louisiana (both the prairie and alluvial lands) is suitable to the 

 cultivation of Rice, lending itself readily to irrigation, both from rivers 

 and canals, and from artesian wells. 



There are three chief varieties of Rice amidst many others, viz. 

 Carolina, Honduras, and Japanese. The latter stands milling better than 

 the two former. 



The cultivation is difierent in the allu\dal sections from that followed 

 on the prairies. 



The adoption of suitable fertilisers and a system of rotation are 

 recommended. 



II. Bad weeds that infest the Rice-fields are as follows : — 



Red Rice, Large Indigo {Sesbania macrocarpa), Curly li\(\.\go {JEschij- 

 nomene virginica)^ Tadpole-grass {BJiynckospora corniculata), Bull-grass 

 {Panicum agrostidifonne), Smartweeds {Polygonum), Turtle-back {Diodia 

 teres), Bird's-eye {Scleria — several species). Morning Glory {Ipomoea 

 tamnifolia), Water-grass {Paspahim flidtans), Moss-weeds . . . besides 

 other miscellaneous weeds. — H. C,
