The anthracnose. ( Gloeosporiwm venetum) is another serious disease 

 with which we are not so well able to scope. It has been found by 

 studies at the Connecticut station that a hyphoe of this fungus do not 

 extend from the old to the new canes as in the red-rust, so that if all 

 diseased portions could be cut away it would doubtless prove an effec- 

 tive remedy. The fungus is so general and indiscriminate in its attacks, 

 howevei", that in most cases this is wholly impracticable. It is difficult 

 to combat it with spraying also, for the reason that it is so hard to get 

 all portions of the canes protected with a coating of the material used . 

 Professor Green, of Ohio, who has made some experiments, finds reason 

 for encouragement in spraying with Bordeaux mixture, but believes 

 it will be found necessar}'^ to begin with young ' plantations and treat 

 them thoroughly every year. This disease is usiially first noticed 

 upon the canes as discolored and sunken patches, although it may 

 attack the leaves also. When the injury to the canes is well seated, 

 the berries fail to mature and dry up and hang on the stems, and the 

 growth is slight and sickly. The disease is wide-spread. (See Fig. 9 

 in Bulletin XIX). 



Another disease is becoming quite prevalent on our grounds and has 

 also been observed elsewhere, which manifests itself bv large knotty 

 swellings on the roots. So far, we have observed it only on Turner and 

 Hansell raspberries. Its cause seems to be a mystery as no insect or 

 fungus has been found in connection with it. Affected plants lose 

 their vigor and productiveness and it is common in the rows affected. 

 So far, the only thing that can be said is to avoid setting plants which 

 show such swelling on the roots. I am afraid that this disease is more 

 common and widespread than anyone knows. Weak and unproductive 

 patches in berry plantations should be examined for this root-gall. In 

 some parts of Western New York a root-gall of insect origin has been 

 serious, bat the present disease appears to have a different source. 



The Dewberry of the Pacific Coast. — Within the last two or three 

 years, varieties of dewberries which are wild upon the Pacific slope 

 have been introduced to cultivation. These dewberries do not appear to 

 have been studied and they have not been referred to their botanical 

 species. The Skagit Chief and Belle of Washington were received 

 from Washington (State) and planted in the fall of 1891. They have 

 made a very long slender growth, lying flat upon the ground, and in 

 appearance they are very different from the eastern dewberries. The 

 Skagit Chief blossomed this season and it proved to be pistillate 

 with no stamens or pollen whatever. These varieties belong to the 

 species JRubus vitifolius, of the Pacific coast. This is a very peculiar
