The Silver Medal for the best bloom of a 
Hybrid Perpetual in the show, was awarded 
to Mr. Cant for a flower of Madame Gabriel 
Luizet; the Silver Medal for the best bloom of 
a Tea-scented variety to the same exhibitor 
for a flower of Souvenir d’Elise Yardon, a 
remarkably grand bloom; and the Silver 
Medal for the best Noisette was awarded to 
Mr. J. Walker for a bloom of Triomphe 
de Rennes. Amongst Yellow Roses, Mr. 
Prince’s Jean Ducher took the first place, Mr. 
B. R. Cant’s Marie Yan IToutte the second, 
and Messrs. Curtis & Co.’s Marechal Niel the 
third. 
Alexandra Palace Show'. 
This show, which took place on July 8th, 
was, as compared with former years, com¬ 
paratively limited, but nevertheless some 
good collections were staged by Mr. B. R. 
Cant, Messrs. Paul & Son, Mr. C. Turner, the 
Cranston Nursery Co., and Messrs. W. Paul 
& Son, the latter not for competition ; as well 
as by several amateur growers, amongst whom 
E. R. Whitwell, Esq., and J. Wakeloy, Esq., 
took the lead. One of the prettiest depart¬ 
ments of the show w T as that devoted to 
bouquets, prizes being offered in separate 
classes for bouquets of wdiite, pink, yellow', 
dark, and mixed Roses ; and in these Mr. G. 
Paul and Messrs. Kinmont & Kidd w r ere the 
wdnners of the principal prizes. There w'as a 
class for one thousand trusses of Roses, in 
which Messrs. Paul & Son were the only 
exhibitors. Though limited in extent, and 
lacking in high quality, the show was a very 
pretty one from the popular point of view.—

GEOS MAROC GRAPE. 
f YEAR or two back Messrs. Rivers & 
Son exhibited before the Fruit Com¬ 
mittee of the Royal Horticultural 
Society a large-berried Black Grape, 
called the Gros Maroc, the merits of which 
were at once recognised. I remember at the 
time the remark W'as made that it was a 
wonder how it had come to pass that so 
good a Grape was not more cultivated by the 
great growers. Since that time I have growm 
and fruited it, and I must say that I am 
more than surprised to hear from time to 
time of so many recognised fruit-growers who 
do not even know the name. I myself con¬ 
sider it a most valuable addition to our fruit- 
houses, as it is a strong-growing Grape of 
vigorous constitution, very prolific, with fair¬ 
sized compact bunches, and very largo berries. 
It is, without exception, the finest colouring 
Grape I know, and is worthy of a place in the 
most limited collections. —John Cox, Redleaf. 
MILKY SICKNESS OF PLUM 
LEAY T ES. 
S7JT T this season of the year one often 
y-1 observes, both on wall and orchard 
trees, branches on which the surface 
' of the leaves has become whitened as 
if milk had been poured over them. It is 
most assuredly an unhealthy symptom, and in 
fact marks a peculiar diseaso which in the 
first place makes itself manifest by the milky- 
white appearance above referred to, and sub¬ 
sequently results in the decay and death of 
the affected branch, and ultimately of the 
whole tree. The disease is very common on 
Plum-trees, but is by no means confined to 
them, being also met with in the Apricot, 
the Peach, the Almond, the Portugal Laurel, 
and other trees of the same affinity. Though 
most abundant on orchard trees and wall 
trees, its ravages are not confined to trees 
out-of-doors, since those grown under glass 
are sometimes also attacked. 
The presence of the disease is not easily 
accounted for, as it shows itself in various 
localities, and under different conditions of soil 
and exposure ; but no doubt seems to exist 
that it is the work of a fungus. This view is 
supported by an account given by the Rev. 
M. J. Berkeley (Gard. Citron., n. s., xiv., 
464) of some specimens sent for examination 
by Mr. Harrison Weir, of the trunk and roots 
of a Plum-tree so affected, which Mr. Berkeley 
describes as follows :— 
“ Two sections of a Plum-tree have been forwarded 
to us, affected with that milky appearance of the 
leaves which is due to the separation of the cuticle 
from the cellular tissue of the leaf. This affection is 
very common in Apricots, and occurs also in other
