ber 27 to October 2, 1909. The members collected during each 

 day and met for the discussion of interesting specimens and the 

 reading of papers in the evenings. 



The fourth annual report of the Forest Park Reservation Com- 

 mission of New Jersey, published in September, 1909, includes an 

 illustrated article of twenty-four pages on the planting and care 

 of shade trees, by Alfred Gaskill, forester; one of sixteen pages 

 on insects injurious to shade trees, by John B. Smith, state ento- 

 mologist; and one of twenty pages on the fungi of native and 

 shade trees, by Byron D. Halsted, botanist of the State Experi- 

 ment Station. These three articles probably constitute the most 

 comprehensive and helpful publication on the care of American 

 shade trees to be obtained anywhere. 



Arrangements are being made to hold the first meeting of the 

 American Phytopathological Society in connection with the Amer- 

 ican Association for the Advancement of Science at Boston, Mas- 

 sachusetts, during Convocation Week, December 27, 1909, to 

 January i, 19 10, at which time questions relating to the future 

 policy of the Society and its relations to Section G of the Amer- 

 ican Association for the Advancement of Science will be defi- 

 nitely determined. 



The biology of Armillaria mucida Schrad. is the subject of a 

 paper by C. E. C. Fischer in the Annals of Botany for October, 

 1909. The fungus was artificially grown from spores, and several 

 fruitless attempts were made to introduce it as a parasite into 

 the beech tree, on which the sporophores are commonly found. 

 Owners of beech forests are advised by the author to keep wounds 

 on their trees covered with an antiseptic, and to destroy dead 

 infected timber and young sporophores before they are able to 

 shed spores.
