prominent place for ornament in tlie shrubbery. All of the 
varieties grow freely in any good garden soil. 
The Snow-Drop Tree — Halesici. — When in flower, the snow- 
drop .or silver-bell tree is one of the most beautiful objects 
among shrub trees. The tetraptera or four-winged halesia 
produces a profusion of pure white flowers, like snow-drops, 
hanging in small clusters of four to eight all along its branches, 
that open during the last of April or early in May, before the 
leaves have grown, giving to the tree a most unique and 
beautiful effect from its waving, drooping mass of snowy white 
laced with the lines of dark brown from its branches. It makes 
a tree in height from fifteen to twenty feet. 
The dijptera or two-winged halesia does not bloom as early as 
the four-winged, but its flowers are larger and even more pure 
white, so that when in bloom the tree excites the admiration of 
all beholders. The foliage is larger and broader than the tetrap- 
tera, and altogether it is a variety that should be planted in all 
collections of any extent. As small lawn trees, or for prominent 
positions in small yards, both varieties are worthy a place, and 
when planted in front of a cluster of evergreens their beauty is 
much increased in effect. 
The Sweet-Scented Shrub — Calycanthus. — The sweet- 
scented shrub or allspice — calycanthus floridus — is a low shrub 
with broad, dark brownish green foliage and dark brown ‘wood, 
producing a dull, dusky, chocolate-colored flower highly per- 
fumed, as is also the foliage, but less strong ; and it is 
from this peculiar and agreeable perfume that the plant 
obtains universal favor and introduction into even the smallest 
gardens. Its growth is usually three to four feet high and as 
many broad, blossonfis mostly produced in June, although, in 
some seasons, occasional flowers are produced until autumn. 
There are quite a number of varieties, varying in the form of 
foliage ; and where room can be had for a cluster, their intro-
