syringe must be dispensed with. See that the trees have 
abundance of water at the root whose crops are stoning, and 
as soon as the fruit again begins to swell manurial waterings 
may be afforded when water is necessary, replacing the mulch 
afterwards. Quassia, or “ Abo-1 ” washings may still be put 
on the trees where black fly are troublesome.

Hardy Trees and Shrubs. 
The exhibit of cut specimens of trees and shrubs staged at 
the recent Holland House Show from here has caused many in¬ 
quiries, and, for the benefit of the readers of The Gardening 
World, I will mention a, few of the most beautiful and rare 
which do well here and have proved to be perfectly hardy, as, 
by so doing, it. will enable those who contemplate making a 
choice collection and planting in the autumn to- make a note of 
the same. 
One of the principal families were the Acers, and these, of 
course, are all grown for the beauty of their foliage. A. car- 
pinifolium, a Japanese species, with le-avesi similar to the 
common Hornbean, succeeds well in a loamy, clay soil, and 
sunny position. A. platanoides Schwedleri, with extremely 
handsome red foliage and bright red young shoots, is desirable 
for planting in avenues, and, when grafted on to an 8 ft. to 
12 ft. stem, has a tine effect. This needs a moderate amount 
of pruning to keep it shapely. A. platanoides laciniata, com¬ 
monly called the Hawk’s-fo-ot Maple, is appropriately named, 
the leaves being deeply cut and curled, resembling the foot 
of this bird. A. platanoides albo-varie-gata. is one of the best 
variegated shrubs, succeeding well in. a partially shaded posi¬ 
tion, so that the sun does not burn the foliage, and, as with 
the preceding, needs but- little pruning. 
Conspicuous varieties of the Acer pseudo-platanus type are 
Simon. Louis Freres-, with variegated foliage, a most handsome 
tree; Worleyi, young foliage golden; Leopoldii, white 
variegated leaves; and purpurea Nizetti, having purple leaves, 
variegated on the upper surface, and slightly glaucous beneath. 
The variegated Ash-leaved Maples or Negundo-s are fairly 
well known, A. fra-xinifolium albo--variegatum and A. f. aureo- 
variegafum having white and yellow variegated foliage; while 
the somewhat, new A. f. ealifomicum aureum has golden 
leaves. Whether grown, a-s specimen trees, or as dwarf shrubs-, 
the Negundo-s- likes a go-o-d open position. 
Avery fine variety of the commo-n English Maple is A. cam- 
pe-stre pendula. foliis maculatis-, the foliage being prettily 
variegated, and when, grafted as a standard of medium height, 
the habit is clearly demonstrated. The weeping form of the 
Tree of Heaven, Ailanthu-s. glandulosa. pendula, has large, droop¬ 
ing foliage, and A. flaves’ce-ns o-r Ce-drela sinensis is- reddish- 
purple in. a- young state. Very little pruning and an open pos-i- 
tion. will suit them well. One- of the finest- Chestnuts- is 
Aesculus Hip-pocastanum aureo-marginatum, the foliage being 
heavily edged with gold. A. Hip-pocastanum 1 acini at om is in¬ 
teresting on account of the foliage being so finely divided. 
For growing by the water the- Alders are well suited. The 
bright golden, variety, Alnusi glutino-sa. foliis aureis, is the 
showiest, and the cut,-leaved form, A. glutino-sa. laciniata, im¬ 
perials, grows quickly and is, veiy pleasing. 
The Celtis cr Nettle Trees are all worth growing for their 
foliage, and like a moderate amount of pruning. C. occidenta-lis, 
'■ °- reticulata, and C. australis- are all good. Two- very 
ornamental forms- o-f AmygdaJus are A. dulcis- purpurea, with 
deep purple foliage, and A. orientalis, a silvery-leaved variety ; 
t iough not a quick grower, it is conspicuous. The former re- 
quue-s pinning somewhat freely. AraMa Maximo-wiczcii is one 
or the handsomest o-f shrubs, having large divided foliage-, and 
requires little or no pruning. 
Castanea sativa argent e-o-varie-gata and C. s. aurexv 
vanegata are both very fine, the- latter having more gold than 
green in the leaf, and should be planted where the sun. will not 
injure it. C. americ-ana rubra has- large leaves, reddish in 
colour. A handsome shrub is Cercidophyllum japonicum, the 
foliage in spring being a bright red. Clerodendron trichoto- 
inum is orie of the bes-t o-f flowering, shrubs, which should not 
be disturbed after planting, and pruned very lightly. 
Some-_ of the bes-t Dogwo-o-ds are- Comus- alba Sp-aethii, a 
golden fo-i in , C. florida- rubra, with large- fo-liage, soon grows 
into- a small tree; C. Mas- aure-a- ele-gantisshna, a combination 
o-f green, golden and pink colouring; C. Mas variegata, and 
C. siberica eleganitis-sima, the- three- lash locking extremely we-ll 
as- standards, and requiring but little attention. 
Euonymus- alatus americanus is valuable- for its beautiful 
autumnal tints. 
Fagus sylvatica. foliis argenteis, the. variegated Beech, is-very 
ple-asing, and so is F. sylvatica. tricolor, which s-uccee-ds well 
in this- clay s-oil. The- Aucuba.-le'ave-d Ash, Fraxinus excelsior 
aucubaefolia, with its golden variegated foliage-, makes- a. hand¬ 
some tree, and shows to the best advantage when backed up 
with some dark-leaved trees. 
Parrot,ia. persica is very fine in the autumn, and requires an 
open position. 
Pyrus Aria, aure-a, the golden-leaved variety o-f the Wlrite- 
Jf 3 ' 1 ?’.?? ra l tE&r slow growing, but very bright in colour, and 
the Willow-leaved Pyrus-, salicifolia pendula, is- one- of the best 
weep mg trees, with silvery-white foliage. 
Others equally good are Quercus pedunculate Concordia, the 
Golden Oak ; Bhamnus alp-inns la-tifolius, with very We 
eaves-; R. Frangula, asplenifolia,; Sambucus nigr-a- aronmteo- 
vanegata, silvery variegation and small growing; Uhnus 
Be-rardia, miniature Elm ; M. campestris Louis- Yan Ho-utte, 
with golden foliage; Virgilia, lute-a, and Zantho-xylum fraxini- 
folnnn, with leaves like the- common Ash, and known as the 
Toothache Tree. A E Thatcher

1 bo Cattleya, House.—The plants which usually make the 
display in this division during the- summer months bavin- 
passed out. of bloom leave- somewhat of a- blank at the- present 
season, and render the house less attractive to casual visitors 
but gives the season, o-f most interest to the grower, as- he- is 
looking forward to the advancement- of growth in the many 
stages of development- at which we find our plants- at the- present 
season. To do- our best for the future welfare-, and, if possible 
to procure better results than previously, and, above- all things’ 
to produce p-lant-s equal to the best to be se-en, elsewhere °is- 
the chlet ami o-f our most enthusiastic cultivators. It is obvious 
from these remarks that unless eve-ry careful attention is- given 
during this the most, interesting- portion of the year, we cannot 
hope to procure the fruit of our labour in the future results 
produced at the flowering period. 
Tl ie _ season, so- far, has not been one- likely to assist the 
maturity of the growth in, its development, 'it is- necessary 
therefore, to afford the plants- the advantage of as much strong 
light as possible, with due regard to protection from injury 
fiom the scorching rays of the s-un. The autumn-flowerino- 
varieties, such as Cattleya, superba, C. dowiana, C. bowrino-iana, 
and the hybrids- derived fro-m the use of the last-named parent,' 
form a most useful and interesting group in themselves. 
The hybrids derived from the- influence of La.elia crispa, the- 
various members of the L-aelia anceps- group, and others o-f the 
Mexican section of Laelias should have- every encouragement to- 
enable them to mature and thoroughly ripen their growths, 
without which it will be impossible to- hope to- procure satis¬ 
factory results when, the flowering season arrives. Our short 
summer season is quickly passing, and unless every opportunity 
is taken advantage of I am afraid it will be a difficult matter 
to mature the growth now advancing before the- dull season sets 
in. Insect pe-sts must be guarded against-, as, with the high 
temperatures now raging, these pest-s make havoc in a short 
period, and are difficult afterwards to be got rid of.
