enable farmers in the clover-producing States to continue the growth of this 

 crop with more certainty of success than is at present the case in many sec- 

 tions." 



A description of the plant and statements of its history, distribution, and soil 

 and climatic requirements are followed by discussions of the following topics: 

 Obtaining a stand, handling the crop, red clover in mixtures and in rotations, 

 red clover as a feed and a soil improver, seed production, varieties, insec-t 

 enemies (by F. M. \V('l)stor). fungus diseases, and clover sickness. 



Inheritance of row-numbers in maize ears, J. Buutt-Davy (Xntiire [Lon- 

 don], 86 ( tOJl), \o. 2167, pp. 3.'i7, 348).— The Arcadia White Sugar maize is the 

 result of a cross between the 8-rowed Blaclv Mexican and a white flour-corn 

 which normally bears a large number of rows. Thirty-three plants of Arcadia 

 bearing 2 well-developed ears each were studied with special reference to the 

 number or rows. In 12 plants the lower ear had as many rows as the upper 

 ear, in 18 cases it had more, and in 8 cases fewer. Among the 6G ears 11 were 

 8-rowed, 23 10- rowed, 30 12-rowed. and 2 14-rowed. 



Maize from Nyasaland and the Gambia {Bui. Imp. Inst. [8o. Krnsinrjton], 

 8 {1910), ^o. .'i, pp. 360, 370). — These pages report the results of the examina- 

 tion and valuation of white and yellow maize samples submitted by the director 

 of agriculture at Zomba and described as grown in the Port Herald district. 



The shrinkage of corn in storage, J, W. T. Duvel and L. Duval {U. 8. 

 Dept. Agr., Bur. Plant Indus. Circ. 81, pp. 11, figs. 3). — This is a statement of 

 observations made on 500 bu. (28,000 lbs.) of shelled corn stored in the wooden 

 hopper of a scale in a Baltimore elevator. The corn remained in the hopper 

 from January 5, 1910. until 'Slay 14, 1910, without handling " It was then run 

 out of the hopper and elevated 3 times to the same scale," and laid 18 days 

 longer, making 147 days in all in storage. 



On January 5 the average moisture content of thelcorn was 18.8 per cent. 

 Its temperature and that of the air were 20° F., its germination test 89.6 per 

 cent, and its weight per bushel 54.7 lbs., while 97.1 per cent of the corn was 

 sound. On June 1 the moisture content was 14.7 per cent, the weight per 

 bushel 50 lbs., the germination test 1 per cent, and only 1,1 per cent of the corn 

 was sound. The total shrinkage during the storage period of 147 days, ex- 

 clusive of the loss of 448 lbs. during the 3 elevations, was 1,522 lbs., or approxi- 

 mately 5.6 per cent. 



It was observed " that whenever there was an increase in weight or a re- 

 tardation in the shrinkage the relative humidity of the atmosphere was very 

 high between weighings, and in most cases a heavy rainfall occurred .iust before 

 such weighings were made." The shrinkage in weight from January 5 to April 

 21, while the corn remained in good condition, was approximately four-tenths of 

 1 per cent, but from April 21 to May 14, during which time the corn became 

 sour and hot, with a maximum temperature of 138° F. on May 2, the shrink- 

 age was approximately 2.6 per cent. During the 8 elevations on May 14, on a 

 basis of the actual weight of corn in the hopper just before handling, the 

 shrinkage was 1.65 per cent. After the corn had been cooled to 55° F. by 

 handling, the shrinkage in storage from May 14 to June 1 was 2.6 per cent. 

 So long as the corn remained in good condition its rate of shrinkage was 

 largely influenced by the relative humidity, air temperature, and other weather 

 conditions. 



The problem of the improvement of cotton in the United Provinces of 

 Agra and Oudh, H. M. Leake and A. E. Park {Agr. Jour. India, 6 {1911), No. 

 1, pp. 1-13, pis. 5). — A review of the problems involved in cotton improvement 

 in Agra and Oudh is followed by a discussion of progress already made.
