Discussion. 



Samuel H. Warren asked whether the painting of flower pots 

 was injurious to the pots, or to the plants grown in them. 



Mr. Hews replied that if the plant was properly watered, no 

 injury would result from the paint. He also remarked that one 

 experienced plant-grower said " we shall not reach perfection in 

 growing plants in pots, until we do away with porous pots, and 

 thus avoid the growth of green mould upon the outside of the pots 

 when in use." The Japanese always grow plants in glazed pots. 



William C. Strong said that if we can have our pots burned so 

 hard that green moss will not grow upon them, it will be an 

 improvement of great value. 



Mr. Hews remarked that F. L. Harris, of Wellesley, always 

 wants the hardest pots, and added that his firm sent a schooner 

 load of hard burned pots to Port-of-Spain, the capital of the 

 island of Trinidad, to a firm who grow palms there.

Fungous Diseascs op Ornamental Plants. 



By Professor Bvron D. Halsted, Botanist and Horticulturist at the New Jersey 

 Agricultural Experiment Station, New Brunswick, N. J. 

 I 



In the brief time that is before us it may be well to make a 

 visit to some large grower of ornamental plants under glass, and 

 pass from house to house upon a tour of inspection. This series 

 of greenhouses will be ideal in the sense of offering examples of 

 many of the leading kinds of fungous troubles. 



Without further preliminary parley we will consider ourselves as 

 having arrived upon the grounds of our florist friend, who gives 

 us the freedom of his houses while we discuss the subjects that 

 are to come before us.
