PARK AND CEMETERY. 
homa roots live vigorously and send up as many 
young trees as will be allowed. The writer remem- 
bers an old garden, in front of a ott.ige, that had a 
Locust in one corner. A wind storm blew the tree 
down and it was chopped up, carted off, and the 
stump carefully extracted from the ground. The 
occupants vacated the cottage, locked the gate, and 
no one occupied the place till the war, then pre- 
vailing, was over. On the return home, the family 
found two years’ growth of Locusts all over the 
premises. Crowding the front steps and over- 
growing the walk were Locusts. The pinnatified 
foliage is light and feathery, and the young trees 
graceful in form, but, out of place, nothing is con- 
sidered handsome. It was chop and dig on that 
place for many days to get rid of the volunteer 
Locusts. 
Another tree of still more objectionable quali- 
ties is the Cut-Paper Mulberry ( Bronssonetia Papy- 
rifera), which is largely grown all over the United 
States. It is hardy, free and handsome, acquiring 
great size, and heavily clothed with leaves that are 
rough above, downy beneath, serrate, somewhat 
heart-shaped, and three-cleft and variously lobed. 
The cut, or serrated, and lobed form varies with 
almost every leaf, which has given the tree its pop- 
ular or common name. The objection to the tree 
is the exasperating power of growth possessed by 
the roots, and the marvelous vitality of the young 
plants these rizhomessend up. So far do the roots 
run, and so large and strong do they grow, that 
underground, bricked and cemented cisterns, and 
wells heavily curbed, are upset and ruined by 
them, proceeding probably from a tree twenty or 
forty feet away. They run under houses, and if 
the house is raised sufficiently to show light under- 
neath, the suckers will grow so freely they have to 
be kept cut down regularly. The writer has lived 
on a place where the Mulberry furnished grateful 
shade over a wide expanse of back yard, and in the 
front yard, or flower garden, has had the gardener 
to take hold and pull up young mulberries, when 
from one plant ten yards of fibrous, tough, yellow 
roots, would be found under the soil. Wherever 
these roots are cut a junction is formed that pro- 
duces at once the growth of a sucker, which speedily 
develops a sturdy sapling. 
Nevertheless, it is a popular tree. It is rapid in 
growth, long lived, and handsome at all seasons, 
particularly in the fall, when the leaves turn to 
bright gold color. Calves and cows are fond of the 
yellow leaves, and so abundant are the leaves that 
one large tree will feast a cow and calf during the 
fall. White rabbits (favorite pets of the writer) 
dearly love the young mulberry sprouts, and as 
these are not confined to spring, but come up freely 
all the year, except winter, are always at hand for 
the warren. 
The rizhoma root growth is the objection to each 
of these trees, for parks. They will be sure to 
invade surrounding territory and keep a gardener 
on the watch for intruding suckers.

THE TEMPERATE HOUSE. 
In contrast to the curvilinear Palm House — the 
Temperate House is heavier in constructive ma- 
terial. The vertical sides are all glazed between 
the angled stone pilasters. While rather depressed, 
the wide span roof is light and strong, and main- 
tains a good architectural proportion between part 
and part. Rather than continue the wjde roof from 
wall to apex in unbroken breadth, the monotony 
that would thus obtain is relieved by another verti- 
cal glass side half way from outer wall to purlin, 
and from here the roof continues lantern style to 
the summit. From this design is taken a three-fold 
advantage: (i) a reduction of the necessary 
greater massive and light - obstructing frame 
work .to a minimum; (2)utilizing the purlin 
supports as a gallery walk and overlook, com- 
passing the inside house, and (3) taking the 
advantage of a vertical side at this elevation 
for ventilating purposes. The otherwise plain 
joint at the apex of the house is decorated by 
a light ornamental fence-like ridging of iron up- 
rights. The entire house, mounted on a wide 6-ft.- 
high grass terrace, has a broad-side facing, either 
end having a lower, narrower, and subordinate 
rectangular wing balanced by well-proportioned 
connecting octagons. An entrance is provided in 
the center of the extreme opposite ends of the long 
edifice, but the main two are located opposite and 
in the center of the two longitudinal sides of the 
principal structure. The gables are of a size and 
ornament in keeping with the expression of the 
whole house and add to its dignity. In design, it 
is plain, yet artistic ; rich, without tawdriness. It 
has an architectural expression, and withal instantly 
commends itself as serving the practical purpose of 
plant growing, without the sacrifice of individual 
beauty. 
Sir William Hooker, in his annual report to 
Parliament in 1858, urges the necessity of this large 
plant house for the reception of the large collection 
of taller growing tender plants indigenous to tem- 
perate climes. In England there had previously 
existed no large plants of this particular sort that 
made it possible to estimate what proportions they 
might attain, and having provided the large one for
