REPORT OF THE SUPERINTENDENT OF BUILDINGS AND GROUNDS 
Dr. N. L. Brirron, Dirrector-1n-CHIEF. 
Sir: I have the honor to submit the following report as 
Superintendent of Buildings and Grounds for the year 1916. 
Regulating and Grading 
Most of this work was done at the rose garden, conven- 
tion garden, and the iris garden. We regulated, graded, 
and made ready for planting 15 X 200 feet along Pelham 
Avenue and 15 X 180 feet along the Southern Boulevard. 
More than three-quarters of the rose garden is regulated, 
graded, and ready for planting. About an acre of ground 
between the large lake and the eastern boundary line of 
the Garden, to be used for the instruction of school teachers 
in gardening, has been cleared and plowed. 
Contractors who were excavating cellars in the vicinity 
of the Garden and who were looking for a convenient place 
to dispose of the soil have carted 11,000 cubic yards of 
earth into the grounds, depositing it to our satisfaction at 
their expense. About 1,000 yards of this soil has been 
placed at the quarry near the iris garden, 3,000 yards north 
of the Woodlawn Avenue approach, and 7,000 yards at the 
northern end of the large lake near the rose garden for 
filling in the new road. 
From paths now under construction at the convention 
garden, along Pelham Avenue, and through the Magnolia 
collection, 3,200 cubic yards of top-soil were transferred 
to the rose garden. For the purpose of filling in the new 
road at the northern end of the large lake, 2,000 yards of 
fill were removed by our carts from the bank on the northern 
side of this road.
