Carnations, Bud Rot of. By F. D. Heald {U.S.A. Exp. Stn. 

 Nebraska, Bull. 103 ; 1908 ; with five plates). — After enumerating ten 

 fungus diseases attacking carnations this report describes the " bud rot," 

 which is attributed to Sporotrichum anthophilum (Peck), in which two 

 kinds of spores are produced, inicroconidia, nearly globose, and simple, 

 and macrcconidia, which are elongated and generally uniseptate. This 

 mould is parasitic on the filaments and petals of carnations, discolouring 

 them and spoiling the flowers. It is recommended to pick off all 

 affected buds, and burn them, practise clean culture, and keep the moisture 

 down to the minimum. A mite is constantly associated with the fungus 

 in affected buds (also described with two plates). — M. C. C. 



Cassava Starch, Industrial Prospects in Jamaica. By the 



Hon. H. H. Cousins, M.A., F.I.C., F.C.S. {Journ. Imp. Dep. Agri. W.I. 

 No. 3, 1907). — This paper states the yield of tubers, their maturation and 

 varieties ; cost of production, manufacture, commercial value of cassava 

 starch, and concludes that the intrinsic qualities of cassava starches 

 producible in Jamaica are of a high order, and a well-made article can 

 command a high price. It would appear that this industry offers a field 

 for investment and development whereby large areas of land at present 

 of small productive power could be made to yield a handsome profit.

Chrysanthemums : Fall of Flower Buds. By A. Morel {Le Jard. 

 vol. xxii. No. 501, p. 13 ; January 5, 1908). — In Show Chrysanthemums, 

 e.g,, ' Duchesse d'Orleans,' ' Tokio,' and 1 Mile. Debonno,' the fall of 

 llowor buds (indicated by the appearance of a horizontal slit above the 

 bud, which then drops off before it opens) may be averted by making two 

 or three vertical cuts, of 1-2 cm., immediately below the bud. The sap 

 then runs out, and the fall is prevented. Another interesting obser- 

 vation is that of M. Poiret, who produced more vigorous plants and larger 

 flowers, which also develop earlier, by making an annular incision in the 

 stem, fifteen to twenty days after disbudding, 5-10 cm. from the ground.
