protection to the new ones as they grow up. 
11. Fruticetum. 
The plateau west of the Bronx, bordered on the south by 
the present bog, on the west by the New York & Harlem Rail- 
way, and on the north by the bog garden, is selected as a 
most desirable tract to be devoted to the systematically planted 
collection of shrubs. It is structurally a terrace, the upper 
soil being two or three feet of loam, the lower portion to the 
depth of at least 12 feet is a coarse gravel. There are no 
trees worthy of permanent preservation growing upon it. We 
find that about 850 species of shrubs, exclusive of numerous 
other species, which are on the border line between herbs 
and shrubs, or else are low woody plants, and which we plan 
to grow in the herbaceous grounds, may be expected to thrive 
in the open in our latitude. We have carefully assigned space 
for each of the families, following a nearly natural sequence, 
arranged in a curving line around and through the middle of 
the tract, leaving considerable areas of greensward between 
each family. The arrangement is thus very elastic, permit- 
ting nearly double the space which we have allotted to be 
ultimately devoted to each family, without disturbing the na- 
tural sequence. 
The systematic grouping of the shrubs in the fruticetum 
does not in any way contemplate their rejection in the plant- 
ing of the arboretum; and it is proposed that the paths and 
driveways in the arboretum be bordered, to a greater or less 
extent, by shrubs of the same natural families as the trees in 
their immediate vicinity, planted, however, not for speci- 
mens, but mainly for landscape effect. 
The fruticetum is intersected by a portion of the longi- 
tudinal driveway system west of the Bronx, by the transverse 
system extending from the Mosholu Parkway to the Bronx 
and Bleecker Street, and by paths so located in relation to the 
planting that all the genera of shrubs cultivated shall be easily
