for four months and the mansion for two months by running 
the gasoline engine for two weeks. We have continued to 
uproot the poison ivy throughout the grounds. 
On Saturdays, Sundays, and holidays from June to 
September, we had two city officers in civilian clothes and 
with our two regular keepers and twelve additional guards, 
selected from the gardeners and laborers, the grounds 
have been well protected. At all other times during the 
year one city officer was detailed to the Garden. The 
number of visitors on Saturdays and Sundays during the 
summer months averaged about 40,000. This number 
was greatly increased during July and August. Owing to 
the watchfulness of our employees little damage has been 
done to the plantations throughout the Garden during 
the year. 
A wire fence, three feet high, has been erected to protect 
the 2,500 red pines which have planted near the Iris Garden. 
Respectfully submitted, 
Artuur J. Corsetr, 
Superintendent of Buildings and Grounds.

of the room will proceed without delay and will be much
