gave especial attention to collecting the lichens of the region 
for comparison with those of the West Indies and to the 
study of plants collected in gardens, parks and nurseries, 
some of which we secured for our greenhouse. 
Some collecting for the local herbarium was done by 
members of the staff in northern New York, Connecticut 
and New Jersey. 
Our West Indian collections have been further increased 
by specimens collected by Mr. William Harris in Jamaica, 
by Brother Léon and Brother Hioram in Cuba, and by 
Mr. L. J. K. Brace in New Providence, Bahamas.

Pursuant to our request for a special appropriation of 
$5,000 for completing the unfinished driveway through the 
eastern part of the reservation, referred to in my report 
for the year 1918, this amount was granted during the 
summer by the Board of Estimate and Apportionment, 
after application by Hon. Joseph P. Hennessy, Commis-

made available for expenditure late in November. Work 
in grading, rock excavation and paving northeast of the 
rose garden was immediately begun by a force of workmen 
of the Park Department, and continued until December 31. 
All grading was completed during this period and all but 
about 200 feet of road area was paved; enough stone to 
complete this paving is readily available and work may be 
resumed within a short time. Provision is made in the 
city appropriation for supplying and rolling in the broken 
stone and screening required to complete the work, also 
for oiling the surface; we may therefore anticipate the 
completion of this much needed driveway in the spring. 
It will be recalled that our plan contemplates the closing of 
the narrow dangerous road leading north from the Mansion 
after the new broad driveway is opened for traffic. 
At conservatory range 2, the plaza at the west end of the 
central display greenhouse was materially enlarged in
