1388. Mottet, S. Pommes de terre de grande consommation. [Principally used potatoes.] 

 Revue Horticole 91: 232-234. 1 pi. (colored). Feb., 1919. — A critically descriptive list of 

 several mid-season and late varieties of potatoes. The author states that he has previously 

 published two other articles on the same subject. — E. J. Kraus. 



1389. Mullet, H. A. Lolium subulatum, Vis., "Wimmera" rye-grass. Jour. Dept. 

 Agric. Victoria 17: 266-278. Fig. 6. 1919. — A hardy species of rye-grass hitherto unrecorded 

 in Victoria, and of great promise for sowing of pastures in the wheat belt. The root system 

 is fibrous and extremely vigorous. The seed is larger and plumper than average samples of 

 rye-grass, and is capable of retaining its vitality for several years. Propagation is by seed 

 only. The stems possess the usual purplish base characteristic of rye grass. The grass does 

 better on the red clays than on friable black soils. It is stated that Lolium subulatum will 

 double the stock carrying capacity of the present Mallee pastures. — J . J . Skinner. 



1390. Muller, B. [Rev. of: Ranninger, Rudolf. Die Kultur des Mohnes. [Culture of 

 poppies.] Nachr. Deutsch. Landw. Ges. Osterreich 1917 10 : 89. 1917.] Biedermann's Zentralbl. 

 Agrikulturchem. 47: 254-256. 1918. — Poppies were planted in rows respectively 60, 50, 40, 

 30, 20, and 10 cm. wide while the plants in the rows were respectively 50, 40, 30, 20, 10, and 

 5 cm. apart. Rows 30 cm. wide and plants 20 cm. apart in the rows gave very favorable re- 

 sults, for most of the plants produced 3 to 4 capsules. Descriptions are given of the care of 

 the plants and the collection of the capsules. The yield averaged about 1700 pounds per hec- 

 tare. The weight of a hectoliter varied from 56 to 63 kg.- — F. M. Schertz. 



1391. Muller, B. [Rev. of: Koritschoner, Fr. Die Quecke als Malzersatz in der 

 Brauindustrie. (Couch grass in brewing.) Chemiker Zeitg. 41: 797-798. 1917.] Bieder- 

 mann's Zentralbl. Agrikulturchem. 47: 277-279. 1918. — In Germany it was proposed to use 

 the rhizome of couch grass {Triticum repens L.) in the brewing industry, because of the scar- 

 city of malt. The dried rhizome yields 20 per cent of extract which is derived chiefly from the 

 reserve carbohydrate triticin, which forms levulose on hydrolysis. Difficulties in manufac- 

 ture were great and the beers thus brewed were undrinkable after storage. — F. M. Schertz. 



1392. Nobbs, Eric A. Maize grading in southern Rhodesia. Rhodesia Agric. Jour. 16: 

 5-17. 1919.

 99. 1919. — Satisfactory yields were obtained with Ricinus sanguineus in an area of scanty 

 rainfall (province of Alicante, Spain) without the use of fertilizers. Methods of planting, 

 cultivation, and harvesting are given. — John A. Stevenson.
