Sunflower. The annual plant of 
this name, though a native of Peru, ) 
is of the hardiest of its kind, as it 
only requires sowing in the open | 
border in any common garden soil. 
It is not, however, suitable for any 
situation, unless there be abundance 
of room, on account of the large 
size of its stalks and leaves. The 
perennial kinds are much smaller, | 
and very ornamental ; they are quite | 
hardy, and will grow in any soil and 
situation.

| The Heliotrope is a favourite flower 
in most countries, from its fragrance, 
_which, however, is overpowering, 
/and very unpleasant to those not 
accustomed to strong perfumes. It 
should be grown in a light rich soil, 
and though it requires protection 
during winter, it may be planted 
out in May, when it will flower 
splendidly in the open air, till de- 
stroyed by frost in autumn. It is 
propagated by cuttings, which strike 
easily. 
Heurx.—The Snail.—Snails are 
so destructive to gardens, and par- 
ticularly to those of small size, that 
too much care cannot be taken to 
destroy them. The best time for 
effecting this is in winter or early 
spring, when the snails are in a 
quiescent state, and when they will 
be found in great numbers sticking 
to the walls, under ivy, &c., in box- 
'edgings, or in the crevices of rock- 
work, &c. In spring, the warmth 
and moisture induce them to leave 
their hiding-places, and they com- 
'mence their work of destruction. 
At this season, they should be sought 
for in the day-time, in the same 
kind of piaces as those they select 
| for their winter retreats, and if pos- 
| sible destroyed before they lay their 
bed in February, to plant out in | eggs, which they do in April or May.

a rich sandy loam, and plenty of

tiful little annual plants, natives of

with blue flowers, and very long

the plants planted out in a warm 
open situation in May.

The eggs, which are buried in the 
earth in some rather moist and 
shady place, and which are whitish, 
and quite round and transparent, 
should be sought for and destroyed 
in May or June. By these means 
the ravages of snails may be in a 
great measure prevented ; and there 
will be no occasion to resort to wa- 
tering the beds with lime or tobacco 
water, remedies which, unless very 
judiciously practised, are in fact 
worse than the disease. Many 
persons place empty flower-pots in 
different parts of a garden infested
