M ore (U.S.A. Dep. Agr., Bull. 106).— Cassava is km/wn as ''sweet" and 

 ' bitter " acc rding to the percentage i f hydrocyanic acid present. 



It is chiefly used in the form of meal tor producing a bw grade of 

 starch for gums, pastes, and sizes. It is also used in the manufacture of 

 industrial alcohol. — C. II. L.

Chrysanthemums in Japan. By L. K. (Gard. Chron. No. 1099, 

 p. 42; January IB, 1903). — In this paper it is said that "to see chrys- 

 anthemums cultivated to the highest point of perfection it is necessary 

 to visit the grounds of the Imperial Palace at Tokyo ; there the cultivation 

 of this plant has been carried on for many hundred years, and after 

 passing through these chrysanthemum grounds one has seen the most 

 noteworthy specimens in the land of the Rising Sun. November is par 

 excellence the month in wnich to make this visit, for then the flowers 

 have attained their highest pjint of development. It appears that smaller 

 flowers are more in fashion than they are here, and that a leading feature 

 of their cultivation is to graft several varieties on one plant. As many 

 as forty-five varieties have been grown on one stjck, the result being that 

 the plant looks like an enormous bouquet. The plants are trained upon 

 bamboo frames and vary in diameter from 9 to 11 feet, and carry from 

 4,000 to 7,000 blossoms." — G. S. S: 



Codling' moth. By J. T. Nicholson (U.S.A. Exp. Stn., Oklahoma, 

 Bull. 76 ; 1908). — A life history of the moth is given with some statistical 

 data concerning the position in which the eggs are laid, the greatest 

 number being deposited on the leaf. Trap lanterns were used for catching 

 codling moths between the nights of September 3 and Oct >ber 15, and 

 out of 2,577 insects of different kinds caught, 1,292 were beneficial insects, 

 whdst a large number of others were not harmful enough to be economi- 

 cally considered. — C. H. H.

Cold Storage of Small Fruits. By S. H. Fulton (U.S.A. Dep. 



Agr., Bull. L08 ; illustrated).— Cold storage has been tried in the States 

 with a view to prolonging the season of small fruits, but has not been 

 found entirely satisfactory for this purpose, being apt to cause loss of 

 flavour and moulding. It is, however, very valuable in enabling straw- 

 berries, raspberries, and blackberries to be kept over for a few days in case 

 of need. Foi this purpose a temperature of 36° to 40° Fahr. is best, but 

 the fruit, one* removed from cold storage, should be used as soon as
