Seven years' study of the prevalence of and injuries from scab fungus 

 (Cladosporium carpophilum) confirms the opinion that this fungus is 

 influenced in its development by the amount of rainy weather during the 

 late summer and early autumn. 



The losses from the cracking and rotting induced by the attacks of the 

 scab fungus were very large in the fall of 1902. That these losses may 

 be largely prevented by spraying the foliage is again confirmed. In addition 

 to one spraying before blossoming, there is need of two applications of weak 

 Bordeaux mixture on the foliage about the middle of June and four weeks 

 later. — M. C. C.

* Nitrogen applied in form of clover sown in August and ploughed in in May 1896-1901. 

 t Crop much damaged by storm. 



Each plot contains 48 trees, and is about J acre in extent. 

 The experiment has been carried on since 1896. 



A proportion of the trees died every winter, and were replaced by 

 young ones. 



Thus on Plot A 42 died during the period of the experiment ; on B, 21 ; 

 on C, 25 ; on D, 20 ; on E, 7 ; on F, 5. A half of each plot was limed, 

 and each year since 1900 some trees have been affected by Peach " yellows," 

 usually on the unlimed plots. — F. J. C. 



Peach-growingf in Arkansas. By Ernest Walker (U.S.A. Ayr. 

 Exp. Stn. Arkansas, Bull. 79). — Treats of : — Location, tree and crop, site, 

 aspect, soils, location with reference to transportation, varieties for home 

 market and for shipping, fertilisers and preparation of the land (" worn- 

 out " Cotton fields suited to the deeper-rooting Peach), ploughing in 

 leguminous crops or manuring with bone meal, acid phosphate, and 

 muriate of potash, equal parts of each at the rate of 400 to 600 lb. per 

 acre. Stable manure as a rule is undesirable in Peach orchards.
