a process of selection of fluctuating variations. On September 
25, Mr. John McCallum, a member of the department, brought 
several live hemipeloric plants to the Garden, for the Evolution 
Section, and also for experimental use. On September 27 he 
brought a second lot. These were found near Morris Park, 
Lega 
On October 11 the Garden was visited by Prof. Roland 
Thaxter, of Harvard University. Prof. Thaxter is on his 
sabbatical leave of absence during the current academic year, 
and sailed on October 11 for Trinidad and adjacent regions, 
where he will spend several months collecting both botanical and 
entomological specimens, particularly for the purpose of enlarg- 
ing his enormous collections of Laboulbeniaceae. He will be 
assisted in this work by Mr. J. B. Rorer, a former student with 
Dr. Thaxter, who is now the Mycologist of the British Govern- 
ment on the Island of Trinidad. 
On the afternoon of October 19 the senior class of the Yale 
School of Forestry, to the number of about 25, visited the 
Garden under the guidance of Mr. J. J. Levison, Arboriculturist 
of the Park Department of Brooklyn, and instructor at Yale. 
They were met by the Director of the Garden, and inspected the 
work of soil preparation for the planting of willows and alders 
along the brook, and also the recent evergreen planting around 
the margin of the lake. 
In the preceding number of the REcorp we recorded the 
action of the Board of Estimate of New York City, by which 
about three additional acres of land adjacent to Mt. Prospect 
Reservoir were transferred to the Brooklyn Institute for botanic 
garden purposes. During October, November, and December 
workmen from the J. L. Mott Iron Works have been engaged 
in removing the iron boundary fence and resetting it along the 
new party line. 
The work of enclosing the northeast wing of the conserva- 
tories was completed on December 7. The work on the labo- 
ratory building, which remained practically stationary for over 
eight weeks, owing, in part, to a delay in the delivery of the steel 
trusses for the roof, was resumed on December 9.
