[ Juno 17. 1888. 
otherwise scorching may and often does occur in spite of the ventila¬ 
tion. The admittance of much air, parched it may be, especially on 
days such as now being experienced (June 8th) with the wind in the 
east and a bright sunshine, naturally injuriously increases evaporation 
of moisture from the foliage, and this is diverted from channels where 
it is more required. Besides, it is this absence of moisture from the 
atmosphere and weakening of the growth that encourages the spread 
of red spider, and when once this gains a good hold it is all up with 
the prospect of a well-finished crop. Further, Vines badly infested 
with red spider are so much weakened thereby, that the following 
season they rarely bear so heavily as they ought otherwise to do. 
We find that if we syringe a little thin lime water over the roof 
of any of the fruit houses that are in hot positions or have a great 
amount of glass surface, that this materially lowers the temperature 
directly under, and where it usually gets excessively hot, very much 
hotter in fact than those walking through a house are aware, and as 
a consequence little or no air need be given in front, an advantage 
obvious to all who take more than ordinary interest in such matters. 
Then, supposing the houses are frequently damped down, a very 
congenial atmosphere may be created, and if the thermometer under 
such conditions is run up to 90° during the day, and 5° higher when 
the house is finally closed, no harm will be done. On the contrary, 
a healthy and to me at one time surprisingly strong growth is 
produced. It must be understood that I do not recommend a heavy 
shading, and a thin limewash syringed over is neither heavy nor 
permanent, but if applied with a brush it would be too heavy, and a 
heavy shade at all times is bound to induce a flimsy growth. Should 
we experience a spell of dull showery weather our thin shading dis¬ 
appears, to be renewed in a few minutes when again needed. 
It may be thought that this temporary shading even may interfere 
with the colouring, more especially of the white Grapes, but not if 
the latter are given the amount of time they really require to attain 
perfection. Black varieties may be fully coloured, and yet be sour, 
but not so the white sorts, and these must have time to mature. A 
direct sunshine will quickly colour them to a certain extent, but it 
very frequently disfigures them, as well as impairs the quality. 
Plenty of light they must have, but a thin shading on the roof and 
the Vine leaves overhead will not interfere with a perfect finish, 
always supposing neither shade is not overdone. A moderate canopy 
of healthy well developed foliage—this being assisted by the tem¬ 
porary shading—is really essential to the perfecting of either black 
or white Grapes, and I find that the bunches of any sort if unduly 
exposed are liable to be disfigured by the scalding of the berries, 
especially during the stoning period. Some of the best finished 
Muscat of Alexandria I have yet seen were shown at Bath last 
autumn by Mr. W. Taylor, and I observed that they were grown 
under abundance of healthy foliage. They were allowed plenty of 
time to ripen, consequently the colouring was natural and not 
artificial. Mr. Taylor, as many readers of this Journal are aware, 
is an expert in the art of ventilating, and therefore has less need to 
shade his roofs, but even he when at Longleat found it necessary to 
‘‘do a little to it.” If this is the case with him, how much more so 
is it advisable in the case of those who are less experienced, or who 
cannot if they would attend so closely to the ventilation. 
Not only is it necessary to shade however slightly modern houses, 
but it is imperative where cheap glass has been worked in. The 
latter very often has spots in it as powerful as a good lens, and unless 
shaded over nothing prevents burning in hot weather. We are bound 
to shade portions of our Peach range, and last season especially I 
wished I had freely shaded other portions thought to be safe, as I 
should then have saved a number of good Peaches from disfigurement. 
Even Peaches colour well without direct sunshine, the best we had 
being ripened in a light but not sunny position. A little shade is 
also beneficial to Melons, Tomatoes, Strawberries, and Figs, while 
Cucumbers like it on bright days.—W. Iggulden. 
NEW PLANTS AT REGENT’S PARK. 
As mentioned in our report last week, numerous plants were certificated 
at the last Regent’s Park Exhibition which could not then be noted, brief 
descriptions are therefore now appended. 
Nephrolepis rufescens tripinnatifida (J. Veitch & Sons).—A handsome 
variety, with broad lance-shaped fronds, the pinna much cut on the lower 
side, and the divisions overlapping the others. Very bright green and 
plume-like in appearance. 
_ Rhododendron Gloria Mundi (Veitch).—One of the greenhouse hybrids, 
with large well-formed bright orange-coloured flowers. 
Asparagus verticillatus (Veitch).—A strong-growing dark green plant 
with numerous filiform leaflets round the stems. 
Gloxinia Ivanhoe (Veitch).—A fine variety. Purple with a white margin 
and a dotted throat. 
_ Gyninogramma schizophylla gloriosa (Veitch).—A grand robust form of 
this graceful Fern, the fronds freely divided and very proliferous. 
Imantophyllum Distinction (Veitch).—Very showy, flowers bright orange 
with a pale centre ; of good form. 
Todea g'randipinnata (Veitch).—Something like T. pellucida, but with • 
large graceful fronds. 
Pteris tremula foliosa (Veitch).—A Btrong-habited variety with tall 
fronds, the pinnules undulated on the margin ; very effective. 
Cattleya Wagneri (Hugh Low).—A handsome Cattleya. White with a 
pale golden tinge in the throat of the lip. 
Cattleya Reineckiana (H. Low & Co.).—Sepals and petals white, lip large 
and streaked with crimson. 
Oncidium superbiens (Sander & Co.).—Sepals and lips bright reddish 
brown, petals pale yellow barred with brown. It is similar to O. macran- 
thum in habit, and bears similarly long racrmes of flowers. 
Lissochilus lutescens (B. S. Williams).—A curious little Orchid with small 
drooping racemes, the sepals and petals white, and the scoop-like lip tinged 
with yellow. 
Oncidium Krameri majus (B. S. Williams).—A very large and brightly 
coloured form of this strange Orchid. 
Draccena nobilissima (E. G. Henderson & Son).—A broad-leafed variety, 
6 to 8 inches across, dark red. 
Tuberous Begonia Charmer (Laing & Co.).—Single, bright rosy crimson 
with a white centre. 
Anthericum liliastrum majus (T. S. Ware).—A variety with large pure 
white flowers. 
Pceony Festiua maxima (T. S. Ware).—A large double variety of the 
herbaceous type. White with a few crimson streaks. It was also certificated 
at Kensington on the previous day. 
A circular just issued reminds the public that the Royal 
Horticultural Society’s Provincial Show will be held in the 
Botanic Gardens and Wavertree Park, Liverpool, from June 29th to 
July 5th, 1886, inclusive, the prices of admission being 5s. on June 29th, 
2s. 6d. on June 30th, and Is. on July 1st, 2nd, 3rd, and 5th. The Show 
will be open to Fellows of the Society at 12 noon on June 29tb, and to 
the public at 1 P.M., closing at 7 p.m. On other days the hours of open¬ 
ing and closing will be 10 A.M. and 7 P.M. respectively, except on Satur¬ 
day, July 3rd, when the hour of closing will be extended to 8 P.M. 
Numerous varieties of plants, fruits, flowers, vegetables, hoiticultural 
implements and appliances, will be exhibited, for which, under various 
classes, the sum of £1200 will be awarded in prizes. These prizes are 
open to all competitors who reside in the United Kingdom, but no exhi¬ 
bitor can obtain more than one prize in any class. Valuable awards, 
ranging from £1 to £20, are offered for Orchids and other species of 
plants ; also for cut flowers, fruit an 1 vegetables. Table decoration, 
bouquets, and grouped garden produce will greatly augment the attrac¬ 
tiveness of the Show, as well as offer substantial benefits to successful 
competitors. Eminent firms of seedsmen have offered prizes for various 
kinds of vegetables which are, severally, among their specialities, and a 
most novel and interesting exhibition will be that of horticulture on 
board ship, for which medals will be awarded according to merit. On 
Saturday, July 3rd, and Monday, July 5th, there will be a Cottagers’ and 
Artisans’ Show. The exhibits of horticultural and botanical literature, 
science, and art, will be divided into three sections:—Section A., Home 
and foreign literature of gardening, embracing instruction (elementary 
and advanced), models, diagrams, apparatus, &c. Section B., Technical 
art, such as surveying, plan and architectural drawing. Section C., 
Botanical and decorative art, such as photographs, and drawings in water 
colours and oil, of flowers, fruits, trees, and garden landscapes. An 
incentive to amateurs is offered in a competition for a hand-painted 
china or terra cotta vase, tile, or plate, the subject being flowers, fruit, or 
foliage. The awards will be silver-gilt, silver, and bronze medals. 
,- Applications for space for implements, garden structures, tools 
&c. have been numerous, including space for boilers entered for the 
boiler contest. All modes of heating, ornamenting, and ventilating 
conservatories, &c., meteorological instruments, wirework, tenting, &c., 
will be prominently shown. Certificates will be awarded for any special 
novelty approved of by the Judges that may be brought under their 
notice ; also one or more gold medals for the most meritorious aggregate 
displays in any or all of the classes. There will be a conference on the 
nomenclature of Orchids on Wednesday, June 30th, in which some of 
the most eminent men of the day will participate. The whole Exhibition 
will be one of great interest and value, not only to the general public, 
but also to scientists and practical gardeners ; and persons intending to 
visit the International Exhibition of Navigation, Travelling, Commerce, 
and Manufacture, should make a point of doing so while the Royal
