HARES AND RABBiTs. 
ation, but they all prefer a poor soil 
near water and a sandy situation. 
They are generally propagated by 
layers, though they all ripen seed 
abundantly in England. 
Haxrmope/Npron.— Leguminose. 
—The Salt-tree, H. argénteum, 
Dee. (Robinia Halimodéndron, 
Lin.) is a Siberian hardy shrub, 
which will grow in any soil or situ- 
ation. When grafted standard high 
on a Laburnum, it forms a very 
handsome drooping tree, with sil- 
very leaves and purple flowers. 
Hama'me.is. — Hamamelacee. — 
The Witch Hazel. A hardy shrub, 
a native of North America, which 
will grow freely in any soil that is 
not too rich, though it prefers a dry 
stony gravel. It has the peculiari- 
ty of flowering during winter, be- 
ginning to expand its rich deep yel- 
low flowers just as its leaves are 
falling off, and dropping its flowers 
when its branches begin to be re- 
clothed with leaves in spring. 
Hanp-eiasses—Portable frames 
or covers, formed of iron, zinc, or 
wood, and glazed. These glasses 
differ from bell-glasses in being 
longer, and composed of numerous 
small pieces of glass, which are 
fastened together by narrow strips 
of lead. Hand-glasses are gene- 
rally square, but they may be made 
of an octagon, or any other shape 
that may be found most convenient ; 
and they are sometimes made with 
a pane to open to admit air, or with 
the upper part to take off. This is 
very convenient ; for as hand-glass- 
es are chiefly used for protecting 
half-hardy plants during winter, it 
as the plants seldom want any air 
till they have rooted. 
Harpense’reia. — Leguminose. 
—A new name given by Mr. Ben- 
tham to Kennédya monophy'lla, and 
five other species of that genus, 
which have small purplish flowers. 
Harpy puants are all those that 
will stand the open air in British 
gardens without the slightest pro- 
tection ; half hardy ones are those 
that may be planted in the open 
ground, but require the protection 
of a mat or hand-glass ; and tender, 
those that must be kept during 
winter in a hotbed or plant-house 
heated by artificial means. Green- 
house and frame plants are those 
grown in pots, which require pro- 
tection from the frost during winter, 
and stove plants are those grown 
in a hothouse all the year. 
Haresev_i.—lIt is rather curious, 
that though few poets can write a 
sonnet without mentioning the 
Harebell, and though it is sure to 
be introduced in every eloquent 
prose description of country scenery, 
botanists cannot exactly decide 
what plant is meant by the name— 
some supposing it to be the beauti- 
ful little blue Campanula rotundi- 
folia, and others, the wild Hyacinth, 
Scilla non-scripta. The fact is, 
that both plants are now known by 
the name in different parts of Bri- 
tain: but as the original word is 
said to have been “ air-bell,” it is 
most probable that it was the Cam- 
panula that was first so designated, 
and that is alluded to by the poets ; 
as the tender blue of its flowers is 
so near the colour of the skies, as 
is necessary to give them air every | not to require any great exertion of 
fine day, and it is very troublesome 
to be cbliged to lift the hand-glass 
off the plant, and to lay it on one 
side whenever this is done. Bell- 
glasses, on the contrary, being prin- 
_cipally for preventing the evapora- 
tion of moisture from the leaves of 
cuttings, do not require any opening,

“iy 
poetic fancy to call it a bell of air; 
and as its slender stem has sufficient 
elasticity to rise again when lightly 
trodden on. 
Hares anp Rassits do a great 
deal of mischief to flower gardens, 
as they are very fond of devouring 
many flowering plants—particularly
