Burgess has sent to the Garden seeds from fourteen of the 
species described in the memoir, and guarded pedigree cul- 
tures of these species have been started, with a view to an 
experimental study of the group. 
Meteorological records have been kept during the year, 
including, as usual, continuous records of the temperature 
of the air, of the soil at depths of one foot and of three 
feet, and of the precipitation. The maximum temperature 
of 96° for the year occurred on September 19, and October 
Ig, the minimum of 4° on February 6. The total precipita- 
tion recorded for the year was 41.60 inches, which was ap- 
proximately one inch above the normal for the State of New 
York. 
The Tropical Laboratory of the Garden, at Cinchona, 
Jamaica, was occupied during the spring by Professor Duncan 
S. Johnson, of Johns Hopkins University, and a party of 
students. Professor Johnson carried forward morphological 
and embryological studies, especially in the Piperaceae and 
Chloranthaceae. Dr. Forrest Shreve, of the Woman’s Col- 
lege, Baltimore, Md., accompanied Professor Johnson, and 
made a study of the meteorology and phytoecology of the 
vicinity of the laboratory. A report of Dr. Shreve’s work is 
published in the JouRNAL of the Garden 7: 193. 1906. 
The fresh-water algae of the Blue mountain region, near 
the laboratory, were studied by Mr. I. F. Lewis, and 16 
species, hitherto not reported from the Island, were collected. 
His entire collection represented about 50 species and 30 
genera. 
Mr. W. D. Hoyt investigated the gametophytic stages of 
the Hymenophyllaceae and of Psilotum 
During the summer, Professor A. W. Evans, of Yale 
University, and his assistant, Mr. George E. Nichols, were 
in residence atthe laboratory. Professor Evans made studies 
of the Hepaticae, and Mr. Nichols of the distribution of the 
local mosses. 
A report on the condition of the Tropical Laboratory 
was made to the Board of Scientific Directors by Professor
