at Princeton University. He will continue his investigations in 

 genetics, and will teach a course in development and heredity, 

 open to seniors and graduate students. Experimental gardens, 

 greenhouses, and laboratories are in course of preparation for 

 his work. 



We are glad to correct an error that appeared in the March 

 number by quoting the following, sent in by Dr. Shull: "I note 

 in the last number of Torreya that you mention Dr. Erwin Baur 

 among the botanists who are on the battlefield. This is a mis- 

 take, as Dr. Baur has been retained in the marine ofhce in Berlin. 

 He had alread^^ started on his trip around the world when the war 

 broke out, and for this reason he was not on hand when the 

 marine surgeons were apportioned to the various ships. I have 

 just received a letter from Dr. Baur in which he says that his 

 experimental work is continuing satisfactorily. He has been 

 able to arrange a few days' furlough for the sowing of his pedigreed 

 seeds. He expects to have about 20,000 pedigreed Antirrhinums 

 this 3'ear. Several of his assistants and students are already at 

 work in his garden at Friedrichshagen." 



Mr. F. Schu^der Mathews announces the publication of his 

 Fieldbook of American Trees and Shrubs (Putnams), on which 

 he has been at work for three years. The book describes many 

 wood}' plants of the United States and distribution maps are 

 given for each species. 



Invitations have been issued for a private view of the grounds 

 of the Brooklyn Botanic Garden, including the new Japanese 

 Garden, on June 5. The garden will be opened to the public the 

 next day. Work has recently started on the last section of 

 paths for the garden, on the newly acquired tract ceded b}^ the 

 City of New York which is now being fenced. The total area 

 of the garden is now about 50 acres. 



We regret to record the death of Mr. J. F. Cowell, for many 

 years the director of the Buffalo Botanic Garden. He had made 

 several trips to the West Indies in cooperation with the New 

 York Botanical Garden.
