f a suitable size to contain the fronds without 
jrowding them. The plan is to select a shady 
tuation on the north aspect of a house or wall, 
his ensures the plants being kept cool at all 
mes, and the presence of a house, except in cold 
istricts, renders heating altogether unnecessary, 
Is this Fern will flourish provided frost is merely 
ept out, The frame need not be an expensive 
ne, and if fairly expert with the saw and plane 
ou could make one for yourself wu., a few 
oards. The top should consist of a sash that 
,'ould cover the frame closely, but be movable, so 
hat it could be tilted up for watering and ventila- 
ion occasionally when that is necessary. Yen- 
ilation would tend to harden tne fronds, but 
,-ould only be necessary during warm weather, 
n a frame like this, and the Ferns stood on a bed 
f ashes, very little, if any, syringing would be 
ecessary in order to keep the fronds healthy and 
ippy. Watering should, however, be attended 
i whenever there is a tendency for the soil to 
1st dry. 
ellow Flowers on Laburnum Adami. 
A small tree of Laburnam Adami has given 
.se to a sport with yellow flowers. Is this a new 
ling?—(A. W. D.). 
It is not a new plant at all, but really the 
jnimon Laburnum—that is, when yellow flowers 
apear on Laburnum Adami, which is a remark- 
ile case of a hybrid having been produced by 
•afting Cytisus purpureus on a stock of Labur- 
lm vulgare. The plant is remarkably given to 
wrting back to either or both parents. The 
iort most often consists of yellow flowers, thus 
presenting the original stock of the graft hybrid, 
imetimes, however, the large purplish flowers 
Laburnum Adami give place to a branch bear- 
.g small leaves of purple flowers, which is simply 
ytisus purpureus, one of the original parents, 
his latter form of sport is by no means so 
immon as the yellow. If you wish to preserve 
aburnum Adami, it would be advisable to cut 
i the branch bearing the yellow flowers, as it 
too powerful for the hybrid, and would very 
on utilise all the sap and food supplied, and 
us finally become simply the common Labur- 
im, instead of the graft hybrid, L. Adami. 
ariegated Ivies. 
Would you be good enough to name half a 
jzen of the best variegated Ivies? We have a 
w wall that would be much improved with ever- 
■een climbers like this. They should all be 
»rdy.—(H. C. Spence.) 
Some of the most conspicuous and handsome of 
e variegated Ivies are not quite hardy, so that 
|e have omitted them in the list given. There 
a difficulty in the matter of names, as those in 
irsery collections are often under a different 
une, as too many authorities have been respon- 
ble for the giving of such names. Under such 
^nditions it would be advantageous to visit a- 
jod nursery where Ivies are grown in variety, 
he following are, however, excellent varieties if 
ou can succeed in procuring them : —Hedera 
elix marginata rubra (often named elegantis- 
ma in lists), H.H. minor variegata, H.H. pal- 
ata aurea, H.H. marginata major (sometimes 
■med marginata argentea), H.H. algeriensis 
riegata, and H.H. aurea elegantissima. 
naatos Drooping. 
We have a houseful of Tomatos, most of ther 
ing in good health. A few plants about 2 ft 
gh or a little more are drooping badly. Wha 
you think is the matter with' them?- 
• 0. H.). 
| robably the injury lies at the roots of the 
ints, so that although the stems and leaves 
ve hitherto appeared healthy, the roots may 
in bad condition below the soil. They may 
m be attacked by the fungus which causes the 
epy disease in Tomatos. If the roots are in 
a condition from any cause, it may be that 
3 water supplied is thus checked, and that the 
m aged leaves are unable to supply the moisture 
:essary during the warm weather and bright 
'shine which we have had lately. If the roots 
in very bad condition, it is probably due to 
the fungus above named, and, if so, the safest 
plan would be to lift the plants carefully, and 
have them burned. In doing so, we think it 
would also be well to remove the soil for some 
distance round the plant, and replace it by fresh 
material before you make good the blanks with 
other plants. The soil should also be mixed with 
a good dusting of air-slacked lime before planting, 
and this would tend to destroy any spores about 
Snowy Fly on Ferns. 
Our Ferns in the warm house are badly infested 
with snowy fly. Last year we fumigated the 
house twice, but still they continue to come 
back after a few days. Please say in your 
valuable paper how this pest can be exterminated. 
-(B. E.) 
There is no difficulty in killing the flies in 
the perfect state, but insecticides scarcely if at 
all affect the eggs or the scale-like pupae, which 
may be found like white specks attached to the 
plants. This necessitates a repetition of the 
operation whatever may be tried, but kerosene 
emulsion has been used with excellent effect upon 
plants where fumigation with tobacco paper or 
nicotine vapour has failed. The method of using 
it is to get one pint of kerosene emulsion, putting 
it in five gallons of rain water. The spraying 
should be done in the morning when the 'flies 
are resting quietly upon the foliage, and the mere 
contact of the emulsion with the flies will kill 
them. If you employ the syringe, the very finest 
nozzle you have should be employed for the pur¬ 
pose of making a spray that will just wet the 
foliage thoroughly without running down into 
the pots of soil. If you are at ail expert in the 
use of the jet nozzle and careful, you should 
manage to distribute the spray very finely by 
that means. Possibly, however, a very fine spray 
nozzle would answer better, as it would distribute 
the liquid on the surface and moisten the Ferns 
almost like a fine dew. 
Forget-Me-Not in Spring. 
During the past two months I have noticed a 
fine display of Forget-me-Not in beds of Daffodils 
and Tulips. The plants I have would not flower 
till later on in summer. Please let me know the 
name of the spring flowering one and the method 
of rearing it.—(A. West.) 
There are two spring flowering species, namely, 
Myosotis dissitiflora and M. sylvatica, though the 
latter is the more common and possibly the most 
continuous bloomer during April, May, and June. 
It is a perennial, but we think the best plants 
are always obtained by sowing seeds in the open 
about the end of July or the beginning of August. 
The seeds should be sown rather thinly in lines 
at 6 in. apart, and after they germinate you can 
merely thin them out if too crowded after une 
seedlings get into the rough leaf. By this time 
you can get more bushy specimens to plant out 
in the beds in October when the spring planting, 
including bulbs, is being carried out.
