pleted; this included approaches to the rose garden and 
paths within that garden, and nearly the complete path 
system of the area south of the herbaceous garden, which 
was used during the season for the convention garden of the 
Society of American Florists and Ornamental Horticul- 
turists, now planned for special horticultural plantations. 
Collectively, the number of kinds of living plants now 
represented in the collections is approximately 14,195, 
being a slight increase over the number represented in the 
previous year and the largest number of kinds in cultiva- 
tion in the history of the institution. Additions to the 
museums and herbarium aggregated over 22,000 specimens, 
secured mainly by exchange with other institutions and 
through exploration. The library was increased by about 
895 bound volumes, and now contains about 28,500 bound 
volumes; valuable gifts of books were made by Mr. Nathan- 
iel T. Kidder and by Mrs. George D. Pratt. 
Under the direction of the Endowment Committee, 
plans for the further development of the Garden were pre-

our Landscape Engineer, and his assistant, Mr. L. F. Bird. 
For the construction of two of the greenhouses needed 
at conservatory range 2, Mr. Daniel Guggenheim and 
Mr. Murry Guggenheim each contributed $50,000; Mrs. 
Robert E. Westcott gave $2,000 for building a stone stair- 
way leading down into the rose garden; Mrs. Frederick F. 
Thompson contributed $4,000 for the construction of the 
school garden shelter; Mr. Edward D. Adams presented 
three steel flag poles, costing $918.70; and Dr. and Mrs. 
N. L. Britton have given the cherry garden shelter for 
construction during 1918, an estimated cost of about 
$4,000, the plans for this shelter being contributed by Mr. 
Brinley without charge. The report of the Endowment 
Committee describes these gifts in detail and refers also 
to additional funds needed for endowment.
