 tests at Marseilles with castor bean.] Compt. Rend. Acad. Agric. France 1919: 4.5-47. 1019. 

 — Twenty-three varieties of castor bean were grown at the botanical gardens in Marseilles 

 of which twelve matured their seeds, including all the sorts from Senegal and two Indian 

 sorts. The Brazilian sorts mostly did not mature. — E. A. Bessey.

 [The utilization of grape shoots, seeds, etc.] Compt. Rend. Acad. Agric. France 1919: 156- 

 157. 1919. — Reports investigations of Dr. Ventre on the development of alcohol to the extent 

 of 1.25 to 2.05 per cent in grape shoots placed in the silo, by intracellular fermentation, not 

 by action of yeasts. On distillation 6 per cent of the product is amyl alcohol. The shoots 

 also contain 1.4 to 1.5 per cent of tartaric acid. — E. A. Bessey. 



1073. Lindet. Sur la fabrication de l'huile de palme neutre. [Method of producing 

 neutral palm oil.] Compt. Rend. Acad. Agric. France 1919: 158-159. 1919.— Common palm 

 oil is rancid and very acid due to permitting the fruits to become over-ripe. By picking 

 them just before maturity and boiling immediately in water the oil obtained contains only 

 0.2 per cent acid and can be used for food purposes. — E. A. Bessey. 



1074. McClelland, T. B. Vanilla: a promising new crop for Porto Rico. Porto Rico 

 Agric. Exp. Sta. Bull. 26. 82 p. PL 1-3, fig. 1-4. 1919.— Vanilla (Vanilla planifolia) has 

 never been grown commercially in Porto Rico although conditions are admirably adapted 

 for its production. Experimental plantings have yielded at the rate of $400 per acre in the 

 fourth year, and $700 to $900 in the fifth ($2 to $4 per pound). In starting a vanillery it is 

 necessary to plant trees to support the vines for which the leguminous dwarf bucare (/. - 

 thrina corallodendron) is well adapted. A leaf mulch is very desirable. Long cuttings are 

 preferable to short ones. Hand pollination of vanilla is necessary, but the number of blos- 

 soms pollinated has a direct effect on the size of the beans; pollination of a large number of 

 blossoms means the production of short inferior beans. Vanilla culture, because of the 

 small bulk and imperishability of the finished product, is recommended for districts remote 

 from good roads. — Johh A. Stevenson.

 Georgia. Georgia State Coll. Agric. Bull. (Reprint) 145. 12 p., fig. 1. May. 1919.— Con- 

 siders varieties, culture, soil, preparation, spraying, harvesting and fertilization. In dis- 

 cussing fertilizer problems, it is concluded that phosphorus is by far the most important 

 single element in tomato (Lycopersicitm esculentum) fertilization in south Georgia. Phos- 

 phorus in connection with stable manure proved to be the most economical fertilizer. Some 

 of the fertilizer tests led to the conclusion that too much nitrogen might be injurious to 

 tomatoes. — T. H. McHatton.
