important part is played by potash. The crops are considerably heavier, 

 especially in the case of Cherries and Plums. Also, in the trees manured 

 with potash the trunk and branches are better developed, the wood 

 acquires greater power of resistance, the branches are more vigorous, and 

 the flowers and fruit are much less liable to fall. In short, the general 

 health of the tree is improved. 



Fruit-trees in Pots. By 0. Thomas (Garden, No. 1616, p. 328; 

 8/41/1902). — In the autumn, during October, every plant should be 

 repotted ; then all we have to do is to place them out of doors and protect 

 the roots from extreme cold until January, when they should be brought 

 under glass to start growth. Top dressing must be done when young 

 roots appear through the surface soil. Three illustrations and full 

 cultural details are given.— E. T. C. 



Fruit Trees in Prussia. Ed. (Le Jard. May 5, 1902, p. 130).— 

 A census of these shows that, counting only the four leading kinds of

 proportion per cent, of the trees is thirty Apples, thirteen Pears, forty-two 

 Plums, fifteen Cherries. — C. W. D.
