1853. Anonymous. Seed mixtures for land affected by clover sickness. Jour. Bd. Agric. 

 [London] 25:1497-1499. 1919. 



1854. Barber, C. A. The growth of sugar cane. Internat. Sugar Jour. 21: 506-510. 

 1 pi., 12 fig. 1919. — The first of a series of articles discussing certain points connected with 

 the growth of sugar cane is presented for the agriculturalist. This article explains and illus- 

 trates very clearly the growth of a cane plant from both the cane seed and the cane set. — 

 E. Koch. 



1855. Barthe, A. E. Organizacion moderna de los campos experimentales. IV. Auxilios 

 matematicos en los ensayos culturales. [Mathematical aids in cultural experiments.] Revist. 

 Agric. Com. y Trab. 2: 399-406. Fig. 10-12. 1919.— Bibliography appended. 



1856. Biggar, H. Howard. The relation of certain ear characters to yield in corn. Jour. 

 Amer. Soc. Agron. 11:230-235. 1919. — The paper deals with the relation between certain 

 ear characters and yield, in 5 varieties of maize grown at different points. The characters 

 considered are; length of ear, weight of ear, number of rows of kernels and the shelling per- 

 centage. The results show that there seems to be no special relation between number of 

 rows of kernels on the ears and yield, or between shelling percentage and yield. The char- 

 acters of length and weight of ears show positive correlations with yield, but they are not 

 consistently large. The character of length seems to be somewhat significant, at least for 

 some of the varieties. The results suggest that there is no well-marked basis for using ear 

 characters to indicate yield possibilities. — F. M. Schertz. 



1857. Boas. [Rev. of: Die Unkrautbekampfung durch Kainit und Kalkstickstoff auf 

 Ackerland. (Weed control through kainite and calcium cyanamide in arable land.) Deutsch. 

 Landw. Presse 1916:709^717. 1916.] ^eitschr. Pflanzenkrankh. 29:57. 1919— Wild rad- 

 ish, buttercup, lambs' quarters, and dock may be exterminated by application of either sub- 

 stance, with unusually good results. The cost is high. Thistles are resistant. — H. T. 

 Gussow. 



1858. Bracken, John. Sunflower silage. Agric. Gaz. Canada 6:542-543. June, 1919. 

 — Sunflower silage fed to milking cows at the University of Saskatchewan produced slightly 

 more milk, pound for pound, than did oat silage. Yields of sunflowers were twice as great 

 when compared with corn. When the seed is in the milk stage the sunflower crop is considered 

 in the best stage for silage. — O. W. Dynes.
