de M.vzii^RES (A. E.)- L'Abricotier. [The apricot tree.J^iJey. Hortic.

 7 figs. 

 This paper gives information for cultivating the apricot in Algeria. 

 Its insect enemies are few. The larva of the Buprestid, Capnodis 

 tenebrionis, attacks trees already injured through some other cause 

 .and the weevil, Rhynchite^ coeruleus (conicus), attacks the young 

 shoots. Collecting the adult beetles will control the first pest ; jarring 

 the trees and picking and burning all leaves curled by it should be 

 carried out against the second. The larva of the Lepidopteron, 

 Enarmonia {Grapholitha) ivoberiana mines beneath the bark, which 

 must be removed and the attacked branches tarred. The larva of 

 Cydia jwmonella infests the fruit and causes it to fall before maturity. 

 Late apricots are infested by Ceratitis capitata and Drosojjhila. Bait- 

 traps are advised against these two pests, which do much damage, 

 especially on the coast.

 dans les exploitations viticoles. [The preparation of neutral and 

 grey acetates of copper on x'me estates.] — Progres Agric. Vitic,

 pp. 306-308, 2 figs. 



The preparation of acetate of copper on vine estates involves the 

 storage of the wine lees, their acetification, the preparation of the copper 

 audits oxidation, the formation of dibasic acetate, and the scraping off 

 and drying of the copper acetate.
