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 Commission 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 entomologist; and one of twenty pages on the fungi of native and shade trees, by Byron D. Halsted, botanist of the State Experiment 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 American Association for the Advancement of Science at Boston, Massachusetts, during Convocation Week, December 27, 1909, to January 1, 1910, at which time questions relating to the future policy of the Society and its relations to Section G of the American Association for the Advancement of Science will be definitely 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.
