Alcohol bath beneficial to oranges (Vul. Fruit Groicer, 1^1 (4910), No. 1132, 

 p. 5). — Accordiug to this note, D. C Lefferts of the Redlands Orange (irowers' 

 Association has been successful in separating frost bitten oranges from souutl 

 fruit by means of a denatured alcohol bath, the frost bitten fruit being suffi- 

 ciently light to float on tbe top of the liquid. A machine has been devised for 

 carrying on the sepai'ating process. Oranges sul)jected to this bath and exam- 

 ined later in the eastern markets appear to be particularly free from the spores 

 of fungi which cause decay. 



The export of citrus fruits, C. Fuller (Xatal Dcpt. Agr. Bui. 15, pp. 26). — 

 This consists of a rei)ort of the 1908 trial shipments of citrus fruits from 

 Nalal to Europe which were conducted under governmental control, together 

 with suggestions relative to improvements in methods of harvesting and grad- 

 ing fruit. The shipments as a whole indicate the possibility of establishing 

 an export trade with England when the fruit is handled and shipped with care. 



The oraTiges coming from the higher altitudes showed much better keeping 

 qualities than the coast grown fruit. This leads the author to conclude that 

 unless a better keeping quality can be imparted to the oranges upon the littoral, 

 the fruit foi- export purposes nmst be grown at least .■>,000 ft. above sea level. 



Spice, condiinent, and perfume producing plants, J. A. Alkxandek (Jour.

Cofifea robusta, W. J. Gallagher (Dcpt. Agr. Fed. Malay kStatcs Bui. 7, pp.

 here brought together with a view of stimulating the oil i»alm industry in 

 German East Africa. The oil palm (Ehris; guineensis) is discussed relative to 

 its botany, products and their uses, distribution, soil and climatic requirements, 

 races and varieties, culture, harvesting, yields, marketing, and diseases and 

 other enemies.

 information relative to the culture, adaptation, and uses of a number of orna- 

 mental trees and shrubs, principally of Australian and South American origin, 

 which either grow in California or are suitable to that climate. A critical 

 botanical study of the species represented is also included, artificial keys to 

 the species having been prepared for most of the groups, together with many 

 illustrations. Among the groups considered are the Pittosporums, Hakeas, 

 several genera of the Myrtacere, and a number of miscellaneous species.
