234 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, 



Coniferae at Baden-Baden. By E. Arens (Die Gart. No. 2, 

 p. 14 ; January 8, 1910). — In the much colder winter chmate of Germany 

 there are very few of even the most common evergreen trees or shrubs 

 that survive the rigour of winter. There are, however, a few spots where 

 the protecting hills and sometimes also the nearness of the lakes mitigate 

 the severity of the season, and some plants having the benefit of a 

 little varying warm summer for well ripening the wood, and the longer 

 retarding though not very cold winter preventing early growth, do very 

 well. Cunninghamia chinensis, a splendid specimen, almost fault- 

 less, of 11 metres height, and a spread of branches of 10 metres. The 

 circumference of stem one metre from the ground is 1'90 metre. 

 Cedrus atlantica glauca, Cryptomeria japonica, Picea pungens glauca, 

 and several others, which can be grown only in other parts of Germany 

 under cover. — G. R. 



Cool Storagfe of Fruit. By W. French {Jour. Dep. Agr. Vict., 

 September 1909, pp. 589-592). — After describing varieties, keeping 

 qualities, and temperatures, it gives the following as the length of time 

 fruit can be stored : 



Peaches — one to two months at 320 to 34° F. 



Plums— Eight to ten weeks at 32° F. 



Cherries- — ten to fourteen days at 32^ to 34^ F. 



Oranges— One to three months at 34° F. 



Lemons — four months at 38° F. 



Grapes— three months at 33° to 36° F. 



Strawberries — four weeks, if covered with cotton wool, at 32° F. 

 Currants — four to six weeks at 32° to 34° F. Eed varieties keep 

 better than black or white, and should be protected by paper covering. ! 

 Tomatos (ripe) — one to two months at 42° F. — C. H. H. 



Copper-soda for Apple Scab. By J. Oromin (Jour. Dep. Agr. 

 Vict., September 1909, p. 588). — The best time to spray is when a few 

 of the blossoms are opening and the bulk of the flower buds are showing 

 with distinct stems. Copper-soda is probably as effective as Bordeaux { 

 mixture under all circumstances. It certainly is so in districts where j 

 the weather conditions are fairly dry at the blossoming period. Bordeaux | 

 mixture, owing to the lime in it, adheres to the trees better than the 

 other wash, and is preferred where heavy rains occur in spring. The 

 difference in cost is that between the soda and the lime. Only positively 

 fresh lime is serviceable, so that some waste usually ensues. The 

 copper-soda is more easily mixed and applied, and is a much more 

 pleasant mixture to use generally. The accepted proper mixture for | 

 copper-soda wash is made thus: dissolve 6 lb. bluestone in 25 gallons 

 water, in which it should be suspended (placed in a piece of hessian). 

 In cold water it will dissolve in a few hours; if required quickly, it 

 dissolves 'm a few minutes in boiling water. Dissolve 8 lb. of washing 

 soda in the same manner in another vessel containnig 25 gallons water; 

 when dissolved add evenly together into the spray barrel.— C. H. H.
