This collection has been used by many students during the 
year and has now become complete enough to afford a good 
general view of all the natural plant families containing her- 
baceous species hardy in our climate. 
The large number of different kinds of plants brought to- 
gether on an area of about eight acres has naturally afforded 
a constant change in color effects from week to week as the 
plants successively came into bloom and this, together with 
the large amount of greensward between the plots and the 
forest surroundings of the glade, have made this plantation 
exceedingly attractive. 
2. Fruticetum. During the planting season of both spring 
and fall, species of shrubs additional to those set out in the 
autumn of 1898 were installed on the plain northeast of the 
Museum Building. The collection of shrubs thus grouped 
in natural families now contains 338 species, which is a gain 
of 143 species over the record of 1898. The collection now 
contains enough kinds of shrubs to fairly represent all the 
natural families in which shrubs are included, hardy in this 
climate, and it has come to be of value to students, who have 
used it in considerable numbers. 
The Salicetum or Willow collection has been installed on a 
part of the marshy ground northeast of the Fruticetum. 
3. Arboretum. Tree planting in accordance with the 
scheme contemplated by the general plan has been carried on 
during both spring and fall. The number of species of trees 
now in piace, including those native to the grounds or long 
ago established, aggregates 160, 
4. Viticetum. The collection of vines which had been 
brought together in the nurseries was transferred during the 
spring and fall to the rustic arbor built last winter; the num- 
ber of species now included in this collection is 45. 
5. Wurserves. No additional space has been taken into the 
nurseries during the year, the amount of land already under 
cultivation having proved sufficient. Among the most impor- 
tant collections of seeds sown in the nurseries during the 
spring were those received from the Royal Botanical Garden at
