increase is considered sufficient to pay for the extra cultivation. Sub- 

 soiling in January was quite beneficial to the firsl crop but it afforded 



in) increase the second year. 



Kows 3 ft. I in. aparl gave practically the same yield whether the 

 plants were 12, 18, or 24 in. aparl in tlie row, but when the distance 

 wxs increased to 30 in. the yield was noticeably reduced. 



Applying 640 lbs. of slaked lime per acre broadcast showed no 

 increase in tlie cotton crop that year, but the next year cotton, follow- 

 ing cowpeas which were turned under in the spring, yielded more on 

 the [>la1 limed the year before than on the plat which had not been 

 limed. A mixture of barnyard manure, cottonseed meal, and acid 

 phosphate was more effective when applied without composting than 

 when composted about 1 month before using. Bedding on all the fer- 

 tilizer gave better results than reserving one-fourth and applying it in 

 the drill at planting time. An application of 150 lbs. of cotton-seed 

 meal per acre resulted in a larger yield of seed cotton than the appli- 

 cation of .'!l(i U.s. of cotton seed or 70.5 lbs. nitrate of soda, these quan - 

 tities furnishing equal amounts of nitrogen. Acid phosphate proved 

 to be more effective than Florida soft phosphate except when the crude 

 phosphate was employed in compost, A mixture of these two phos- 

 phatie fertilizers was less effective than an equal weight of acid phos- 

 phate and more effective than the same amount of Florida soft 

 phosphate. Cotton-seed meal, acid phosphate, and kainit were applied 

 singly and in different combinations at the rate of 200, 240, and 200 lbs. 

 per acre respectively. The use of kainit alone was most profitable, 

 and cotton seed meal alone stood second. Acid phosphate applied 

 singly gave no increase in yield. The apparent average increase 

 in yield of seed cotton per acre due to the different fertilizers applied 

 to plats which had received no fertilizer, or which received kainit 

 or acid phosphate or both, was 116 lbs. for cotton-seed meal and 151 

 for kainit. and a decrease of 103 lbs. for acid phosphate. 



Topping cotton did not prove profitable. 



Red rice, W. K. Dodson (Louisiana Stas. Bui. 50, 2. ser.,pp. 208-226, 

 />!. l). — A description of red rice is given and the results of experiments 

 conducted to ascertain its origin are discussed. The flower of the rice 

 plant and the natural provision for preserving the seed of red rice are 

 described. The author points out the disadvantages of reel rice in rice 

 tields, considers its botanical relations, and makes suggestions how to 

 prevent its occurrence. A test of 17 varieties of rice is reported. The 

 « speriments led to the following conclusions: 



•• Red rice is a differenl variety from the white rice. White rice will not produce 

 red seeds when the seed a have been exposed to the weather all winter, as is com- 

 monly believed by planters. Tlie two varieties will cross, producing hybrids, and 

 tin-,, hybrids tend to revert to one of the parent forms, the red rice being a little 

 Btronger. 



•• Bed rice, being dependent upon self-preservation, is hardier than the white rice
