NOTES, NEWS AND COMMENT. 
Dr. W. L. Johannsen, professor of plant physiology in the 
University of Copenhagen, who has been delivering a course 
of lectures in Columbia University on ‘‘The Modern Principles 
of Heredity”’ was a recent visitor at the Garden. 
Recent reports from Dr. W. A. Murrill as to the conditions’ 
for fleshy fungi on the Pacific coast are most favorable and the 
trip will result in the addition of many interesting species to the 
mycological herbarium. 
The second meeting of the Torrey Botanical Club for this 
season was held in the main laboratory of the museum building 
of the Garden, October 25. The meeting consisted of informal 
reports by a number of the members. 
Dr. E. D. Clark, instructor in biological chemistry in Colum- 
bia University, has been awarded a research scholarship at the 
Garden to assist him in carrying on some investigations in certain 
phases of plant chemistry. 
The first of the autumn conferences was held in the main 
laboratory of the museum building on Monday, November 6. 
A full account of this meeting will appear in a later number of 
the JOURNAL. 
Dr. William H. Brown, a student at the tropical laboratory 
during the summer of 1910, has recently been appointed plant 
physiologist in the Philippine Bureau of Science, Manila. 
The Control of the Chestnut Bark Disease is treated by Haven 
Metcalf and J. F. Collins in farmers bulletin No. 467 issued by 
the United States Department of Agriculture, October 28, 1911. 
The total financial loss from this disease is now estimated at 
$25,000,000. The only known practical means of controlling 
the disease in a forest is to locate and destroy the advance in- 
fections as soon as they appear. Advance infections should be 
located by trained observers and destroyed by cutting and burn- 
ing. Chestnut nursery stock should be rigidly inspected and 
only perfectly healthy plants passed. The life of valuable orna-
