With the above percentages and tallies showing the total yield of 

 green and dry material at diflerent dates, the amounts of the different 

 food constituents and ash contained in the plant at various stages of 

 growth are worked out. Thus July 10, when the plants were just 

 coming into bloom, the date of greatest total yield, the nitrogen-free 

 extract constituted 2,033 lbs. of the total yield, protein 1,333 lbs., 

 crude fiber 905 lbs., ash 556 lbs., and fat 159 lbs. These constituents 

 were greatest for the whole plant, leaves, and stalk on this date. The 

 leaves were especialh^ rich in food constituents, containing "about 

 ten-thirteenths of the protein of the plant, about thirteen-twentieths 

 of the nitrogen-free extent, and about thirteen-sixteenths of the fat, 

 while they contained very little more than one-third of the crude fiber." 



These data suggest the early blooming- period of Golden Vine field 

 peas as the most suitable time for harvesting to secure the greatest 

 amount of dry matter and of food ingredients. 



Rice — preparation, cultivation, flooding, and harvesting, W. C. 

 Stubbs {Loiusiana Sta.s. Bnf. 61^ -2. se/:, pj>. J7G-4-01, jd-s. lU). — The 

 lands best adapted to this crop, methods of soil preparation, planting, 

 flooding, and harvesting the crop, varieties cultivated in both the allu- 

 vial and prairie sections of Louisiana, composition of rice and its 

 straw, etc., are popularly discussed. Some data regarding the pro- 

 duction of rice in Louisiana, irrigation methods emploj^ed, money 

 invested in irrigation plants, and the acreage under irrigation are 

 included. 



In 1899 Louisiana produced 107,792,000 lbs. of rice. It is estimated 

 that about 8,000 square miles of the alluvial and prairie lands of the 

 State could, with some expenditure of money, be brought under culti- 

 vation and irrigation where they would be valual)le for rice cvilture. 

 With the present yields something like 5,000.00().0»><) lbs. of clean rice 

 could be raised on this land, which is about 12 times the present con- 

 sumption of rice in this country. At the present time there are about 

 •100 miles of canals constructed in the State which irrigate some 225,000 

 acres of rice. These canals are filled mainly b}' the aid of pumping 

 plants.
