ficial media. The bulletin is now ready for publication. It 

 treats of the general character of the disease, the structure of the 

 fungus, its development, and suggestions for treatment. The 

 fungus belongs to a genus which contains several very injurious 

 parasites of plants. 



During the last year I have given considerable time to the 

 investigation of the diseases of timber trees, and a bulletin on 

 this subject is nearlj^ ready for publication. Also a bulletin on 

 anthracnoses of plants which is the result of several years study 

 will be ready for publication before very long. 



Mr. B. M. Duggar, the Assistant Cryptogamic Botanist, has 

 conducted a number of investigations with remarkable vigor 

 and has already accomplished a considerable amount of impor- 

 tant work, though he has been connected with the department 

 for only six months. Besides the work which he did in the 

 Horticultural Schools of the State during the summer and au- 

 tumn, I would call attention to the following investigations by 

 him. He has nearly ready for publication a bulletin dealing 

 with a serious trouble of stored celery. This rot of celery is^ 

 caused by a species of Septoria, which during the summer is the 

 cause of the so-called spot of celery. He has been able to demon- 

 strate that the same fungus carried into the houses in the autumn 

 in storing the celery spreads there on the plants with entirely^ 

 different appearances and effects. He has also in progress an 

 investigation on several different kinds of rot of celery grown 

 in houses during the winter. This will in the future be pre- 

 sented as a second bulletin. Another very important piece of 

 investigation is that of the pear and quince leaf spot, which 

 owing to the long period required for the complete development 

 of the parasites connected with it, will require a longer time for
