Pelargonium, New Zonal, 'Yvan d'Angeniecq ' {Rev. Hon. 

 April 11), 1908, p. 170).— New variety raised by M. Bruant, Poictiers, 

 distinguished by its richness and variety of colour, viz., an intense violet. 

 Robust and free flowering from spring to autumn. — C. T. D. 



Persimmons, Japanese. By F. H. Burnette (U.S.A. Exp. Stn., 

 Louisiana, Bull. 99, December 1907; illustrated). — The native fruit 

 having been grown for many years in Louisiana has prevented much 

 interest being taken in the Japanese variety, which, however, can be grown 

 productively in the Southern States. 



In Japan Diospyros kaki takes the place of the apple, and is of great 

 economic importance. Its astringent qualities when unripe are corrected 

 by some native method, at present not fully understood in America, but 

 when this is remedied the fruit is sure to increase in favour, being prolific, 

 easily grown, transported, and marketed. 



It requires little pruning, as its tendency with years is to overbear. 

 It has few diseases and enemies, and is ornamental as a tree. 



The persimmon has a high percentage of sugar, and an alcoholic 

 beverage is made from the fruit in Japan. — C. H. L.

Potato Tuber, Dry Rot of the. By Dr. G. H. PetHybridge and 

 E. H. Bowers (Econ. Proc. Boy. Dublin Soc. i., pt. xiv., pp. 547-558 ; 

 August 1908 ; 1 plate). — The authors have reinvestigated this disease, 

 and have come to the conclusion that it is due to Fusarium Solani alone, 

 acting independently of any other organism, and that the fungus is a true 

 parasite. Many of the tubers attacked fail to produce plants when used 

 as si ts, and others while in store become shrivelled to a dry hard mass. 

 During the shrivelling the Fusarium pustules appear upon the attacked 

 potato. An interesting account of numerous experimental cultures is 

 given. It is recommended that (1) suspicious-looking tubers observed 

 daring lifting should be rejected and not stored (primary infection is 

 usually from the soil); (2) a careful look-out should be kept for the 

 appearance of the disease, and affected tubers should be removed from 

 the store ; (3) care should be taken to prevent wounding during the 

 lifting and handling of the crop (infection takes place easily through
