nymphaeas. After planting 
them,little attention is necessary. 
If in artificial ponds, six to nine 
inches of water above the crowns 
of the plants will be sufficient, 
and after the plants have made 
good growth the pond may be 
filled, addingabout two inches of 
water every other day. During 
the summer there will be dead 
leaves to contend with. These 
should be gathered from the 
surface, and nothing unsightly 
should be left in the pond. The 
evaporation will be more or less 
according to the condition of 
the weather and the amount of 
living foliage on the surface. In 
any case the pond should be kept full of water. 
Few insects attack the plants, aphides 
(black fly) are the most prevalent, but their 
natural enemies are many, the most notable 
being the lady-birds, or coccinellid<e , of which 
there are several species. The larvae of these 
insects devour the aphides. Insecticide should 
be used cautiously, as the aphides and their 
enemies both may be killed by the same ap¬ 
plication. The safest and surest plan to 
eradicate these pests, if they become such, is 
to collect the lady-birds or the larvae, or both, 
and place them on the infected plants. They 
will very soon fulfil their mission. 
In a fountain basin, where a continual

POND AT KAPIOLANI PARK, HONOLULU 
Showing the effect of overcrowding 
flow of water is maintained, is about the 
worst place to attempt to grow water-lilies. 
Very few plants can exist there. The volume 
ot flowing water changes the contents of the 
basin too rapidly, and also lowers the tempera¬ 
ture, so that conditions are most unfavorable 
and unnatural for aquatic plants. Where there 
is but a limited amount of water—merely a 
spray—several of the hardy varieties of nym- 
LimnanthemumSiEich- 
hornias, Myriophyllum,ttc. In winter, all hardy 
nymphaeas and nelumbiums are best left 
out in the ponds, provided there is a depth 
of water that will not freeze to the bottom. 
Tender nymphaeas must be wintered indoors. 
The amateur with limited 
space and means can indulge his 
fancy in aquaticulture by the use 
of a few tubs. Ordinary barrels 
cut in two are commonly used. 
Only moderate growing nym- 
phteas shou 1 d be put i n an d o ne i s 
sufficient for a tub. Other plants 
besides nymphaeas and nelum¬ 
biums may be grown in larger 
tubs, such as Cyprus (umbrella 
plant), Papyrus antiquorum , 
Eichhornias (water hyacinth), 
Limnanthemums (floating heart) 
with their dainty white flowers, 
and the delicate water snowflake 
with its curious flaky white flow¬ 
ers, various Sagittarius Lim- 
nocharis Humboldti (water 
poppy) and many others.
