Specimen Pot Plants for June and July. — D. W.D .: 
Roses iD pots would answer your purpose very well, 
and they afford almost endless variety. We should 
advise you to get a good amount of variety to begin 
with, so that you may find out which kinds your 
employer likes best, and which do best at your place 
and under the treatment 50U can give them. Those 
things which give most satisfaction should be in¬ 
creased by cuttings, and grown on into useful stuff, 
while the less satisfactory ones might be gradually 
discarded. Amongst Tea Roses you might get 
Niphetos, Souvenir d'Un Ami, Madame Lambard, 
The Bride, Catherine Mermet.and Souvenir de S A. 
Prince. Marecbal Ntel, a Noisette, is the best 
yellow. Hybrid Teas are very useful, and might in¬ 
clude La France, Souvenir du President Carnot, 
Kaiserin Augusta Victoria, and others of that class. 
Amongst hybrid perpetuals choose General Jacque¬ 
minot, Mrs. John Laing, Charles Lefebvre, A. K. 
Williams, Ulrich Brunner, Madame Gabriel Luizet, 
Baroness de Rothschild, Paul Neyron, Merveille de 
Lyon, &c. Other plants you might procure are 
Hydrangea hortensis, H. Dr. Hogg, H. paniculata 
grandiflora, Choisya ternata, Fuchsias of sorts, 
Chorizema cordata, Clematis Jackmanni, choice 
hardy Rhododendrons, Erica Cavendishi, Erica 
ventricosa magnifica, Statice profusa, S. macro- 
phylla, Pimelea Hendersonii, Pink Malmaison 
Carnation, Carnation Raby Castle, C. Mrs. Leopold 
de Rothschild, Cytisus racemosus, Coronilla glauca, 
Heliotrope President Garfield, and others. Those 
that appear to be Coming into bloom too quickly 
should be stood out of doors in a cool, shady place 
to retard them. Others may be hastened by keeping 
them under elass, or in a warm, sunny position. 
How to Distinguish the British Elms.— E.C.H D.: 
There are many forms of the common English Elm 
(Ulmus campestris) differing remarkably both in 
the habit of growth, size and form of the leaves, and 
in other particulars. Some of them may have 
much the same habit as the Wych or Mountain Elm, 
but the form of the fruit or samara seems to be the 
most constant character. The specimen you sent 
had oblong-obovate, or narrowly obovate samarae, 
with the seed distinctly above the middle of the 
same. It is therefore the English Elm, judged by 
the fruits, as you concluded, notwithstanding the 
habit of the tree, which might be accidental. Ulmus 
montana has a shorter samara in proportion to its 
width, and orbicular or broadly and roundly oval 
with the seed in the centre as nearly as possible. 
The wiDg of the fruit is the thin portion extending 
around the central portion in which the seed is situ¬ 
ated. It is this wing which makes the fruit, 
a samara. The cavity of the ovary is very little 
larger than the seed, the wing being solid and with¬ 
out any internal cavity. It is merely a lateral exten¬ 
sion of the ovary wall, round one edge of the same. 
U. montana has more acuminate leaves than U. 
campestris; and the variety U. montana penduia 
has the largest leaves of any as far as we have seen. 
Choisya ternata Too Early.— T. B.: It is all a 
question of temperature. In the open air about 
London it comes into bloom naturally in May ; but 
in your cooler and later locality you should manage 
to retard the flowers for several weeks longer. Pot 
plants may be kept in a pit or house from which the 
frost is merely excluded in winter. About the begin¬ 
ning of March they should be shifted into a house 
pit or frame, well lighted, but having a cool northern 
aspect, and well ventilated. By this means you 
could retard growth, and the flowers would be kept 
practically in a resting condition. 
Wallflowers Failing.- J. D. M. : Dig up some of 
them and examine the roots. If the latter are 
clubbed it is pretty certain that they have been 
attacked by the Finger-and-toe disease, which is so 
destructive to Turnips,Cauliflower, Brussels Sprouts, 
and the Brassica tribe generally. There is no 
remedy for the plants already attacked. Probably, 
they contracted the disease while still in the seed 
bed where Wallflowers may have been grown too 
often. Next time select a piece of ground where 
none of the Cabbage tribe nor other Crucifers have 
been grown for some years past. Poor soil would no 
doubt be better than rich soil for the young plants. 
A good coating of gas-lime should be dug into the 
soil in autumn, where you intend sowing Wallflowers, 
Cabbages, &c., in spring. 
Raspberry Shoots Flagging.— Nemo : By cutting 
off some of the shoots that appear sickly you will in 
all probability find them bored in the centre by a 
grub, which would be the Red-bud Caterpillar of 
the Raspberry (Lampronia rubiella). The cater¬ 
pillar is reddish with a black head and is the larva 
of a moth. All 3011 can do now is to cut off every 
shoot having the least suspicion of containing a grub 
and burn them so as to destroy the caterpillar and 
lessen or prevent attack next year. If the pith is 
eaten out the shoots cannot recover,so that you need 
not hesitate to destroy the shoots.

NICOTICtDE 
AND 
TRADE MARK. 
BRAND. 
The proprietors of “ Nicoticide ” (Registered Trade Mark), who are the largest manufacturers of Nicotine in the 
World, having observed, with regret, the unnecessarily high prices which consumers of vaporizing compounds containing 
Nicotine have heretofore been compelled to pay, have decided to place on the market themselves, their compound under 
the registered name of “ Nicoticide," at very much reduced prices. The compound is guaranteed to be not only as strong, 
but purer and more efficacious than any at present offered to the public, the Nicotine being extracted from Duty free 
Tobacco, and subject to analysis by H.M.'s Customs. 
The COMPOUND FOR VAPORIZING is sold in bottles, as follows: 
No. 1 size—1 pint, containing sufficient for 40,000 c.ft., 15/- each. 
No. 2 size—i ,, „ ,, 1 , 20,000 „ 7/6 „ 
No. 3 size-6 oz., ,, ,, ,, 12,000 ,, 4 6 „ 
No. 4 size-4 ,, „ ,, „ 8,000 „ 3/- ,, 
No. 5 size—1 ,, ,, ,, 11 2,000 ,, lOd. ,, 
Please see that all bottles bear the word ‘'NICOTICIDE ” stamped on the side, without which none are genuine. In 
order to measure the contents of a greenhouse, &c., multiply the length in feet by the breadth in feet, and then by the 
average height, also in feet—the result is the number of cubic feet contained therein.
