vated the circles around the trees in the pinetum in the im- 
mediate vicinity of this plantation. 
There are now contained in the hardy herbaceous collection, 
including those at the nurseries, 2,948 species and varieties. 
Fruticetum. The progress in constructing roads and paths 
here has made it possible to rearrange the shrub collection. 
A small beginning was made on this during the fall of 1902, 
and the work was resumed early in the following spring. 
The collection has been now entirely rearranged, and each 
shrub has been treated individually, sufficient room having 
been allowed to permit of its unhampered development in all 
directions. To accomplish this required moving some of the 
families considerably from their former position, but the 
sequence has been preserved so that the various families hold 
the same relative position to each other that they did formerly. 
A large collection of herbarium specimens was made during 
the past summer, and these, together with those previously 
made, are forming the basis of a present study of this col- 
lection. 
Immediately following the completion of this transplanting 
came the drought of the early part of last summer, but by 
constant hand-watering during that period permanent harm 
was prevented, nearly all the shrubs having survived. 
There are now in the shrub collection, including those at 
the nurseries, 665 species and varieties. 
Salicetum. The collection of willows and poplars in the 
north meadow has been roughly cultivated during the sum- 
mer by keeping a mowed circle aroundeach one. There are 
in this collection twenty-eight species, represented by eighty- 
eight specimens. 
Deciduous Arboretum. A few additions have been made 
here. Material, however, is accumulating in the nurseries 
which will considerably increase the collection when incor- 
porated with it. We now have, including those in the nur- 
series, 232 species and varieties of deciduous trees. 
Pinetum. The completion of roads and paths in the area 
set aside for the pinetum permitted of the planting during the
