berships at once to the Secretary, J. S. Kerr, Sherman, 
Texas; and don’t delay, for if you wait too long, the 
Badge Book will go to press without your name in it. 
Further details of the approaching meetings will he 
sent out, from time to time, but right now let us have 
your membership, -$5.00 annual fee. All members of 
last year who renew before the first number goes to 
press, will be given the same number they had last year, 
and this of itself, will be quite an asset and advertise¬ 
ment, but a lapse of membership will forfeit the member 
that number. 
Respectfully, 
Will B. Munson, Jno. S. Kerr, 
nearly black or dark blue fruits. This is a common 
northern tree or treelike shrub often twenty or thirty feet 
tall, and just now is a conspicuous feature in many parts 
of the Arboretum. The third arborescent species, V. 
rufidulum, is perhaps the most beautiful of all Vibur¬ 
nums. it is a southern tree which naturally does not 
grow further north than southern Virginia and southern 
Illinois; in the rich soil found along tin 1 borders of river- 
bottom lands in Mississippi, Lousiana and Arkansas it is 
a tree often forty feet high with a tall straight trunk and 
widespreading branches forming a symmetrical round- 
topped head. The leaves of this tree are thick,'dark 
green, and more lustrous than those of other deciduous- 
B. J. Vandervort, Bloomington, Ills., and his new Tractor Tree Digger, manufactured by the Avery Mfg. Co. 
leaved Viburnums. The flowers are pure white and are 
borne in broad, flat-topped clusters, and the fruit is 
bright blue and covered with a glaucous bloom. This 
Viburnum can be distinguished from the other species 
by the rusty brown covering of hairs on the margins of 
the leaf-stalks, branches of the flower-clusters and w in¬ 
ter-buds. It has long been an inhabitant of the Arbor¬ 
etum where, although it is hardy in sheltered positions, 
it is only a shrub and probably will never grow into a 
tree. The best specimen is on Hickory Path near Centre 
Street. Of the shrubbery species now in flower alien 
lion is called to Viburnum pubescens, a plant w ith small 
pointed leaves and small compact clusters of white 
flowers which are followed by shining black fruits. 
There is a large compact group of this shrub on the right- 
hand side of the Bussey Hill Road opposite the upper end 
of the Lilac Group now entirely covered with flowers. 
No other Viburnum blooms more profusely. In the 
same border are now in flower three \ iburnums of tin' 
Opulus section of the genus in which the cluster of fertile 
flowers is surrounded by ;i ring of large and showy, 
white, sterile flowers. On the whole, the handsomest 
of these three plants is the Furopean Viburnum Opulus 
or Guelder Rose. The flower-clusters are smaller per¬ 
haps than those of the other species, but the plant grows 
ARNOLD ARBORETUM 
Viburnums. There are no small trees better suited 
for the decoration of American parks and roadsides than 
the three arborescent Viburnums of the eastern United 
States. The first of these to flower is V. prunifolium, the 
Black Haw of the middle states where it is a common ar¬ 
borescent shrub or small tree on rocky hillsides and in 
fence rows, sometimes growing 30 feet high. It has 
rather narrower leaves than the other arborescent species 
from which it may be distinguished by the absence from 
the leaf stalks of the wing-like margins which are found 
on those of the other species. The clusters of pure 
white flowers are rather smaller than those of the other s 
and the fruit is dark blue covered with a glaucous bloom, 
and remains on the branches until the beginning ol w in¬ 
ter. This is the common tree Viburnum of the middle 
states, only reaching New England in southwestern Con¬ 
necticut. It is perfectly hardy in the Arboretum w here 
it has been blooming for two or three weeks and is now 
passing out of flower. The northern species, Viburnum 
Lentago, the Sheepberry or Nannyberry, has broad and 
lustrous leaves and large clusters of creamy white 
flowers which are followed by sweet and rathei j nic y
