SHRUBS AND VINES 
‘©T sat me down to watch upon a bank 
With ivy canopied, and interwove 
With flaunting honeysuckle.”’ 
—MILTON. 
ITH all their distinctiveness of form and tem- 
perament, one soon finds that trees, shrubs, 
and woody vines are essentially one in nature 
—a classification of convenience, not of science, with no 
organic difference between the trailing arbutus and the 
Sequoia gigantea. The unbroken gradation from the 
clinging ivy to the sturdy oak is so imperceptible that 
precise characterization of the above sort is often diff- 
cult or impossible, and strictly scientific treatment of 
these three forms of growth is comprised under the sin- 
gle title «‘« Dendrologia.’’ 
More than a quarter of all the trees of our territory are 
also to be reckoned as shrubs ; climate and soil largely 
determine whether a species will have the figure and stat- 
ure of the one or of the other; the rhododendron is a 
tree in the Southern States, but only a shrub at the 
North ; black haw and hornbeam assume both forms in 
the same locality ; some diminutive growths havea thor- 
oughly arboreal figure, and some unmistakable shrubs 
are taller than some trees; lofty trees of the far West 
dwindle to low shrubs in the East, and the same is true 
of many species in their northerly and southerly range.
