Financial loss due to weeds; Dissemination of weeds; Chemical 

 herbicides; and a List of plants distinctly poisonous or mechanically 

 harmful to animal life. The larger part of the book, nearly 550 pages, 

 is given to a descriptive list of weeds, in botanical sequence, with 

 indications of the means of Controlling them; and a bibliography, 

 glossary and index complete the work. Though lacking enlarged 

 details, the illustrations well picture the grosser essentials of Iden- 

 tification. Trelease. 



McKay, A. W., Citrus fruit handling and storage. (Proc. 

 Fla. State Hort. Soc. p. 30-45. 1913.) 



A brief review is given of the results of work during several 

 seasons on the blue mold decay of Florida oranges. The careful 

 picking and handling of the Iruit to prevent injury are emphasized 

 in Order to lessen or entirely prevent losses caused by this fungus. 

 The preliminary experiments on grape fruit storage are discussed. 

 The indications given by these experiments were that wrapped fruit 

 keeps better in storage than unwrapped, and that the fruit not 

 washed keeps better than the washed. and that storage improves 

 the quality of grapefruit as determined by chemical analysis. These 

 analyses showed that the citric acid content remained practically 

 constant, but that the sugar content increased during the storage 

 of 2— 4 months by 1 — 1.5 7o. M. C. Merrill (St. Louis). 



Ramsay, H. J., The relation of handling to decay of 

 Florida oranges in transit and on the market. (Proc. 

 Fla. State Hort. Soc. p. 28—42.) 



An address before the Fla. State Hort. Soc. in which the results 

 of the investigations covering six seasons are outlined. Careful 

 picking, handling, and packing of the fruit are emphasized as practi- 

 cable means of lessening or preventing losses caused by the blue 

 mold fungus. It was also found that less decay developed on the 

 unwashed fruit than on those that had been washed before packing.

Im Ganzen lässt sich nach den zahlenmässigen Angaben der Auto- 

 ren sagen, dass die Elektrisierung den Ernteertrag erhöht, aber dass 

 diese Erhöhung noch weitaus nicht in dem Masse ist, dass man die 

 Elektrisierung für allgemeine Praxis empfehlen dürfte. Bei fast 

 allen versuchten Pflanzen hat sich die tügige, im Gegensatz zu der 

 nächtlichen Elektrisierung mehr bewährt. Jar. Stuchlik.
