A weekly award of 5s. will be made by the pro¬ 
prietors of The Gardening World, to the person

news upon passing events likely to interest horticult¬ 
urists at large ; hints containing suggestive facts of 
practical interest to gardeners or growers of plants, 
fruits, or flowers; successful methods of propagating 
plants usually considered difficult ; or any other 
topic coming within the phere of gardening proper. 
The articles in question should not exceed 250 words, 
and should be marked " Competition.” The address

JVe shall be greatly obliged by their so doing. 
[ Correspondents , please note that we cannot undertake 
name florists' flowers such as Carnations, Pelargonium:, 
Chrysanthemums, Roses, nor such as are mere garden 
varieties, differing only in the colour of the flower. 
Florists' flowers, as a rule, can only be named by those who 
grow collections of them.] 
Disease on Bunch of Grapes. — Constant Reader : The 
young berries ot the bunch of Grapes you sent us 
are affected with what is popularly known as the 
“-Spot” of Grapes. A small, irregular, whitish 
patch first makes its appearance on the skin of the 
berries; and this scon becomes brown. By this 
time the interior tissues are considerably affected, 
and shrinkage takes place, this stage being plainly 
observable by the sunken patches and brown colour. 
Some Grapes are more liable to it than others, par¬ 
ticularly Muscats. Many cultivators regard the 
malady as constitutional because it makes its appear¬ 
ance on the same Vine year after year. The popular 
notion is that "Spot 1 is caused by sudden chills 
and checks to growth. This would be caused by 
keeping the house too close and moist and then on 
bright mornings suddenly ventilating too much or 
freely whereby the temperature is lowered and a 
check given to growth. The weather recently would 
have laid the Vines open to such a contingency, and 
you may remember whether you have been ventila¬ 
ting too freely after a spell of dull weather on the 
appearance of bright sunshine. The tissues are 
browned or discoloured right to the interior of the 
cells, that is to the seeds, so that you may burn the 
worst bunches and cut cut the damaged berries from 
the rest. Be careful not to admit cold draughts to 
the house, but air carefully till we get more sunshine 
to harden the tissues, and the malady may not 
spread to any great extent. 
Swellings on the Roots of Cabbages.— R. 
Mathison ; The nodular swellings are caused by the 
Cabbage Gall Weevil (Ceutorhynchus sulcicollis) 
that pierces the roots, and lays an egg in each. 
Grubs batch out, and their feeding inside causes the 
swellings in question. You can see them on cutting 
the gall open. By cutting the gall and removing the 
grub the seedlings may safely be planted. Those 
roots which are much damaged may be burnt or 
otherwise destroyed. If you can save the roots from 
further damage till the plants get to some size, the lat¬ 
ter may produce a good crop in spite of the presence 
of some weevils. You should puddle the roots in a 
mixture of soot and water before planting. This 
will keep the mother beetle from laying her eggs 
there for some time, after which the plants will 
generally be safe. 
A dozen Distinct lyies.— J. Wilson : The following 
should meet your case and give a great amount of 
variety :—Hedera Helix latifolia (the so called Irish 
Ivy with broad leaves), H. H. palmata, H. H. cuspi- 
data major, H. H. algeriensis, H. H. doneradensis ; 
H. H. dentata, H. H. raegneriana, H. H. ficifolia, 
H. H. himalaica, H. H. elegantissima (with a 
beautiful silvery margin to the leaves) H. H. 
rhomboidea obovata, and H. H. conglomerata (a 
very dwarf growing variety). The above are all 
very distinct, but there are many, bushy, upright 
growdng varieties, generally known as tree Ivies 
that are well worth growing. We should ha' r e in¬ 
cluded H. H. madeiriensis, but it is not quite hardy 
for outdoor culture, though very beautiful and worthy 
of the shelter of a greenhouse, pit, or frame. 
Sport on Ampelopsis Yeitchi.— R. Warner : The 
so called sport you send is not a new one. We have 
seen it under the name of A. Roylei. The fact is 
that the plant in question is extremely variable, and 
produces three or four forms of leaves on one and the 
same plant, according to the size, age, and vigour of 
the plant. The leaves may be shallowly or deeply 
three lobed, the former being generally known as A. 
Veitchi. Another form with deeply three lobed 
leaves has been named Vitis tricuspidata. Your 
specimen has the leaves divided into three leaflets, 
and nurserymen sometimes give it the name of 
Ampelopsis Roylei, as above stated. Botanists now 
say that the correct name of the plant is Vitis varia- 
bilis, no doubt in allusion to the variable character 
of the foliage as above described, and which would, 
therefore, be very applicable. 
Climbers for a wall in a Smoky Town.— 
T. Warwick : The deciduous climbers would be the 
best to plant under the conditions you name ; but 
several of the smooth-leaved evergreens also succeed 
very veil. Amongst deciduous kinds you could not 
do better than plant Vitis variabilis (generally known 
as Ampelopsis Veitchi), Vitis quinquefolia (Virginian 
Creeper, more rampant and not so neat as the 
previous one), Jasminum nudiflorum (yellow), 
Jasminum officinale (white), Aristolochia Sipho, 
Clematis montana, C. Flammula, C. Jackmanni, 
Noisette Roses, Honeysuckle, and Wistaria chinen- 
sis. EVergreen subjects are Magnolia grandiflora, 
Crataegus Pyracantha, Cotoneaster microphylla, 
Ceanothus rigidus, C. divaricatus, and many Ivies, if 
you care for them.

TRADE MARK. 
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.
