easiest of application, the cheapest, and most efticieiit method to be 

 pursued for the prevention of this disease. 



Copper sulphate as a smut preventive, S. A. Bedford (6V(«f/</ft 

 Exptl. Farms Rjyt. 1893, JU^- 337, 238). — Exi)eriments were conducted at 

 the experimental farm for Manitoba on the use of copi)er sulphate as 

 a pre\ entive of smut on oats. The seed oats were sjjrinkled with a 

 solution of the funi;icide at the rate of 1 lb. to o bu., and 1 lb. to 10 bu., 

 and then sown at the rate of <> i)e('ks per acre. In each case about .'^0 

 per cent less smutty heads were found in the treated plats, and they 

 yielded G to 1}, bu. i)er acre more than the untreated ones. 



The treatment of diseased sugar canes in the West Indies 

 (Frac. Leen-urd Islandx AgL and CUmunercial *S'oc., 18!)4, Au<i. 3, p. ^). — 

 The suggestions offered by the authorities at Jvew for the repression of 

 cane diseases are: (I) Selection of healfliy plant toi)s, (li) use of disin- 

 fectants on tops before X'lJiuting, (3) cutting out of all diseased canes 

 as far as possible, and (4) burning of all diseased or rotton canes as 

 fast as possible after harvest, together with all trash left in the fields. 



All these methods have been pursued except the last, and it is sug- 

 gested to destroy the s[)ores of the fungus by applying to the trash 

 solutions of corrosive sublimate, Bordeaux mixture, or other fungicides. 

 It is thought this treatment will prove effective, and the cultivator will 

 not lose the trash and tops, which are very necessary to the fertility of 

 the soil.
