 [China Cotton Jour.] 2^: 229-247. 1920.— Reports for the fiscal year ending 1920 of the work 

 at 1 central experiment station and 16 sub-stations with a total area of 1300 mows (Chinese 

 acres). The features reported are: Location, date of establishment, soil conditions, pro- 

 cedure of work, training of students, varieties of cotton, diseases and pests, and results. —

 — The experiments noted were conducted on a farm in Chili, the soil of which was rich in 

 organic substances. The application of sulphur on one plot of potatoes gave an increase 

 over the plots without sulphur of 72 per cent and on another plot an increase of 65 per cent. —

 686. 2 pi., Jf. fig. 1920. — This third paper gives additional descriptive notes and data on 

 three of the lesser millets which are most productive: Bulrush millet (Pennisetum typhoi- 

 deurn), Italian millet {Setaria italica), and Ragi {Eleusine coracana). — C. Rumbold. 



12. Bornemann. Kohlensaure und Pfianzenwachstum. [Carbonic acid and plant 

 growth,] Mitteil. Deutsch. Landw. Ges. 35:693-695. 1920.— More CO2 is evolved from 

 well manured and well cultivated land than from that unmanured or uncultivated. The 

 purpose of the present experiments was to determine whether the larger yields secured under 

 good cultivation were due in part, at least, to the larger amounts of CO2 available to the crop. 

 A portion of the garden was laid out into 12 beds, 6 of which were provided with piping by 

 which CO2 was supplied. Peas, oats, barley, potatoes, onions, and kohlrabi were grown. 

 The plants in the beds supplied with CO2 were later, larger, and more productive than those 

 in the check beds. The following table gives some of the data presented :

 — Use of good crop rotations to increase the yields of wheat and other crops is discussed. 

 Alfalfa and sugar beets can be utilized for their favorable effects. — Chas. H. Otis.
