to abnormal deficiency of chlorophyll was inherited through both parents and 

 followed the Meudelian scheme, the phenomenon being divisible into different 

 and heritable degrees. 



Utilization of crossing for study of phylogenetic questions in connection 

 with, the grains, E. von Tschermak (Ztschr. Pflanzcnziicht., 2 {191Jf), No. 3, 

 pp. 291-312, fig. 1). — The author gives data obtained by crossing among varieties 

 within each of four species of domestic grains, showing in some detail the 

 phylogenetic relations claimed to have been indicated by these results in certain 

 cases, among which are mentioned some alleged evidence of derivation of culti- 

 vated rye from Sccale montanuin, separation of hurleys into a distichum and 

 polystichum series, exclusion of ^Egilops ovata as a primitive form from the 

 ancestry of cultivated wheat, and derivation of some or all forms of domestic 

 panicle and side oats from the wild species Avcna fatua. 



Parallel mutations of CEnothera biennis, T. J. Stomps (Bcr. Dcut. Bot. 

 GeseU., 32 {WlJf), No. 3, pp. 179-188). — Discussing some studies previously 

 reported in part (E. S. R., 28, p. 40), the author claims that there is now no 

 reasonable ground for doubting that genuine mutants have been obtained from 

 (E. biennis. 



Anomalies of development in maize, G. Bohutinsk^- (Bci: Deut. Bot. 

 GeselL, 32 (1914), No. 3, pp. 222-248, figs. 14).— The anomalies of maize here 

 illustrated and described pertain to the shoot, tassel, ear, and grain of this 

 plant, which also shows some interesting peculiarities as regards sex. 



FIELD CROPS. 



Agriculture, Z. Dominguez (Agricnltura. Mexico, 1913, pp. 391-\-XIII, figs. 

 236). — The first 304 pages of this book treat in detail of the production of corn 

 from the selection of seed, culture, harvest, and the manufactured products. 

 The remainder of the book treats, in a general way, of the production of wheat, 

 barley, oats, cotton, and legumes. The work has special reference to methods 

 and systems employed and adaptable to Mexican conditions. 



Intensive farming in India, J. Kenny {Madras and London, 1912, pp. V+ 

 585-\-XI, figs. 2). — This book consists of papers previously published singly and 

 treats of methods of improving agricultural conditions in India, comprising some 

 first lessons in agriculture covering the air, soil, plant, and manures, and includ- 

 ing results of improved methods of cultivation and fertilization with rice, cotton, 

 wheat, sugar cane, tobacco, tea, coffee, coconuts, potatoes, and onions. 



A report of the experimental and demonstration work on the substation 

 farms at Moro, Burns, Redmond, and Metolius. — I, Tillage and cropping 

 methods, H. D. Scuddeb (Oregon Sta. Bui. 119 {1914), pp. IV +188, figs. 87).— 

 " This bulletin is written as a popular report of the experimental and demon- 

 stration work carried on at the eastern Oregon di'y farming substation, Moro, 

 Sherman County ; the Harney branch experiment station. Burns, Harney 

 County; the dry land demonstration farm, Metolius, Crook County; and the 

 irrigation demonstration farm, Redmond, Crook County. It covers the work 

 of each farm since its establishment to the end of the year 1913, giving the essen- 

 tial facts for each as to the conditions encountered, plan of the work, important 

 results obtained, and conclusions and recommendations as to tillage and crop- 

 ping methods, in each different region. No technical discussion of the results 

 obtained is entered upon, if for no other reason than that the work has only 

 proceeded at Moro for four years, at Burns two years, and at Metolius and 

 Redmond one year. All the discussions bear particularly uiwn the advantages 

 and feasibility of a more diversified and intensive sort of farming than that now 

 prevalent in the eastern Oregon region."
