Annual Eeport of the North Louisiana Experiment Sta- 

 tion, 1890, J. G. Lee, B. S. (pp. 100-214). 



The station orchard (pp. 170-173). — A list of the varieties of orchard 

 fruits growing at the station includes 10 of figs, 1 of filberts, 4 of 

 almonds, 6 of quinces, 15 of apricots, 8 of nectarines, 3 of chestnuts, 10 

 of Japanese persimmons, 16 of plums, 34 of pears, 32 of peaches, 40 of 

 apples, and 56 of grapes. 



Live stocJc and poultry (pp. 173-175). — Brief notes on Eed Jersey, 

 Berkshire, Essex, White Chester, and Yorkshire pigs ; Southdown and 

 Shropshire sheep; Holstein and Jersey cattle; and twelve breeds of 

 hens. 



Grain and forage plants (pp. 175-178). — Brief notes on a fertilizer 

 experiment with oats and barley," on 4 varieties of clover and 6 of 

 grasses, and on alfalfa. 



Rotation of crops (pp. 178, 179). — Experiments in rotation of crops 

 have been begun on 3 plats. The rotation will include corn, oats, peas, 

 and cotton. The effects of fertilizers as compared with no manure will 

 also be tested. The results obtained in 1890 on these plats are briefly 

 stated. 



Field experiments with cotton (pp. 179-193). — These are a continuation 

 of the experiments reported in Bulletin IS^o. 27 of the Louisiana Stations 

 (See Experiment Station Record, Vol. II, p. 148), and include investiga- 

 tions on the manurial requirements of cotton on the soil of the station 

 farm, tests of varieties, and of different distances of planting. 



Effects of fertilizers on cotton (pp. 179-185). — As in previous years, 

 these were special nitrogen, i^hosphoric acid, and potash experiments. 

 The questions propounded on the respective plats were, (1) Does this 

 soil need nitrogen (or phosphoric acid or potash) to grow cotton suc- 

 cessfully ? (2) If so, in what form can it be best applied ? (3) In what 

 amounts per acre ? 



Special nitrogen experiments. — Nitrate of soda, " mixed minerals" (acid 

 phosphate and kaiuit), sulphate of ammonia, dried blood, fish scrap, 

 cotton-seed meal, cotton-seed, compost, and kaiuit were used singly and 

 in various combinations and compared with no manure. The soil of the 

 the plat used was quite uneven, but the tabulated results, as in pre- 

 vious exj)eriments at this station, indicate that these particular soils 

 need nitrogen very badly. But it is not so clear which is the best form 

 to use. In 1890 nitrate of soda gave results slightly better than the 

 others, but was closely followed by cotton-seed meal and dried blood. 

 Twenty-four pounds of nitrogen per acre seems to be as much as can 

 be profitably used on these poor soils. 



Special phosphoric acid experiments. — Gypsum, dissolv^ed bone-black, 

 acid phosphate, bone meal, floats, and a basal mixture (cotton-seed meal 

 and kainit) were used alone and in various combinations, and compared
