corn per acre than the un manured plats. On other plats where con- 

 tinuous culture was practiced horse manure produced a greater increase 

 than a mixture of boneblack, sulphate of ammonia, and muriate of 

 potash. Hill planting averaged a little greater yield than drill planting. 



From a comparison of corn and Kafir corn, the author comes to the 

 conclusion that "it is not at all probable that Kafir corn can take the 

 place of common corn to any extent in this State." 



A variety of oats named "Mortgage Lifter" produced the heaviest 

 yield of grain, weighing 38§ lbs. to the measured bushel. Eed oats 

 produced on one plat a higher yield than any recently introduced 

 variety. Winter oats did not prove successful. Horse manure proved 

 to be a better fertilizer for oats than a mixture of boneblack, sulphate 

 of ammonia, and muriate of potash. 



Hybrids from American and foreign cotton, P. H. Mell (Ala. 

 bama College Sta. Bui. 83, pp. 385-412, Jigs. 9, pis. 4). — The author states 

 the propositions to be considered in crossing varieties of cotton, the 

 effects produced on cotton plants by transferring them to different cli- 

 mates and soils, and the requirements necessary to secure perfect results 

 in hybridization. A list is given of the parents, and the botanical 

 characteristics of American and foreign cottons are described and illus- 

 trated. The results of the work are given in tabular form. The author 

 draws the following conclusions: 



"The combination of the Gossypiurn hirautem and G. maritimum yield a cotton plant 

 which produces fiber of the best grade in strength, maturity, twist, length, fineness, 

 and yield per acre. 



"The blending of small and large boll species is not desirable, as a rule, because the 

 resulting forms are generally weak and inferior. 



"The G. maritimum is rather slow in maturing its bolls, and frost is apt to catch the 

 plant in this climate before 60 per cent of the bolls are open. The hybrid procured 

 by uniting ('<. maritimum and G. hirsutem is quicker in reaching maturity and is more 

 prolific. 



"The black, smooth seeds are generally transferred into furrj seeds of a dark brown 

 color. 



"The Egyptian species are liner grades of cotton than those received from India, 

 in length of strands, strength, and texture. They unite, also, more readily with the 

 American species, and the hybrids are generally equal to the parents in qualities. 



"The Sea Island cotton combines with the Afifi and Mannoah to produce superior 

 grade of staple, and the plant is rather prolific. There is a prospect in the present 

 stage of the experiments of securing a variety which will be a healthy, long staple, 

 upland cotton.'* 



Cotton culture in Egypt, G. P. Foaden ( U. 8. Bept. Agr., Office 

 of Experiment Stations Bui. 42, pp. 5-28, figs. 1). — The bulletin describes 

 the conditions of cotton culture in Egypt and the methods of cultiva- 

 tion in use. The price of unginned cotton from 1888 to 1895, the aver- 

 age shade temperatures and the humidity of the air during different 

 months, the soil temperature at different depths, the analysis of typical 

 cotton soils and fertilizing constituents withdrawn from the soils, and 

 the average rainfall at Cairo and Alexandria during each month are 

 given in tabular form.
