warning to growers to avoid buying diseased seed. It is otherwise with 

 the American gooseberry mildew which made its appearance first of all 

 in Ireland. The appearance of the disease is described, and prompt 

 treatment recommended in order to check the disease or to stamp it out. 



Schaffnit-Bromberg * gives a summary of plant-diseases noted in 

 Posen and West Prussia during 1907. Most damage was done to 

 cereals by various species of rust and smuts. The survival of the 

 uredospores of Puccinia dispersa was completely proved. Late sowing 

 of seed is recommended. Notes are added as to the efficiency of 

 the various methods of destroying the fungus. Instructions are also 

 given as to the spraying of fruit trees, etc., and as to the choice of 

 immune potatoes for seed. 



0. Knischewsky | has given a review of the diseases of tropical 

 economic plants in recent years. On cocoa PhytopMhora and Nectria 

 Theobromm have worked great damage. Catling away diseased parts of 

 the host and thinner planting of the trees are recommended. Hymnm- 

 chmte noxia destroys a number of useful trees iu Samoa, Java, and New 

 (iiiinea. Cocoa, breadfruits, Eryihrina Cassia, and others, suffer from 

 its depredations. It attacks the base of the stem and gradually encircles 

 the tree. Pestalozzia palmarum and Lastadia Thece are recorded on 

 the tea plant, PhytopMhora on tobacco, and Septogloewn Manihotis on 

 Manihot. The latter tree is also attacked by an undetermined fungus 

 that destroys the roots and base of the stem.
