each tract. This plan resulted in much more efficient work 
being accomplished. Three laborers were assigned to each 
gardener, with the exception of the fruticetum tract which 
had but one. A special detail was made for the care of the 
deciduous arboretum. 
The tracts were defined as follows, and each gardener held 
responsible for the area under his charge: (1) museum tract, 
all that region between the road connecting the west end 
of the lake and the 200th Street entrance, and the road 
to the eastward of the museum extending as far south as the 
path north of the conservatories, and north to the lake; (2) 
conservatory tract, all that area to the southward of the mu- 
seum tract to the south boundary, and included between the 
elevated railway approach and driving road on the west, and 
the road from the south gate north on the east; (3) west 
border tract, all that section lying to the westward of the 
museum and conservatory tracts and as far north as the lake; 
(4) frutrcetum tract, all the region embraced in the fruticetum 
area including the west border and the salicetum in the north 
meadows; (5) keréaceous grounds tract, the region to the 
eastward of the museum and conservatory tracts and as far 
east as the woodland border, including the viticetum. 
Late in the fall the gardeners were employed in the usual 
leaf-raking in various parts of the grounds; in top-dressing 
with manure of the surface wherever needed; and in tree- 
trimming and the removal of unsightly trees. 
About 769 shrubs and trees were used in decorative plant- 
ing. This material was used in planting the open spaces 
left in the west border and in the low woods east of the fruti- 
cetum when the trestle was removed; in the planting around 
the Mosholu Parkway approach; in the completion of the 
west border between the elevated railway approach and the 
200th Street entrance; and for replacing such shrubs and 
trees as it was desirable to remove from other decorative 
plantations. 
In the herbaceous grounds the low areas lying between the 
brook and the higher ground on the west side have been
