266 EXPERIMENT STATION RECORD. 



found that in soil kept in the apparatus for one hour the nematodes 

 were destroyed, as well as many fungus germs. In order to secure 

 absolute sterility from bacteria and other fungi a much longer exposure 

 would be required. The steamed soil was also almost wholly free from 

 live weed seeds, while untreated soil was considerably affected by 

 them. 



Blight and other plant diseases, C. S. Crandall (Colorado Sta. Bui. 41, pp. 21).— 

 The author has given compiled notes on the cause and means of prevention of the 

 fire blight of the pear and apple. Notes are also given on mechanical injuries to 

 which fruit trees are subject, as well as some of the more common fungus diseases, 

 such as leaf blight or rust of strawberries and orange rust, and anthracnose of black-

Injurious fungi, J. H. Panton (Ontario Agr. Col. and Expt. Farm Bpt. 1897, p. 23). — 

 Brief notes are given on some of the more injurious fungi which affect garden and

 (Jour. Landic. 46 (1898), Nos. 1, pp. 71-74; 2, pp. 97-143, pis. 2).— The author reports 

 studies on the development of the fungus, paying considerable attention to the 

 method of entrance into the host, spread of the disease, method of wintering the 

 fungus, and means for combating the disease.

 ■ checked.
