to furnish lists of their customers, and I think an 
enthusiast would be found in every locality who 
would urge the careless to make returns.— C. K.

MISTLETO. 
At a meeting of the Ealing Gardeners’ Mutual 
Improvement Society lately held, I raised the 
question as to the various trees on which the 
members present had seen the Mistleto growing. 
The result was the mention of ten different trees, 
and ODe member, who was cross-examined on the 
subject,' named the place where he had seen it grow¬ 
ing on an old Gooseberry bush. 
I have since consulted the following authorities :— 
(i) A note in The Gardening World (p. 381) from 
" Syme’s English Botany.” (2) A quotation in the 
same from Dr. Bull, of Hereford. (3) “ The Vegetable 
Kingdom,” by Dr. Hogg. (4) Deakin’s “ Flora 
Britannica ” (5) " Flowers of the Field,” by the 
Rev. A. C. Johns. (6) The ” Edinburgh Cyclopaedia.” 
(7) " Johnson’s Gardeners’ Dictionary.” Theunited 
result is a list of sixteen trees, which includes the 
Apple, Poplar, Oak, Lime, Maple, Thorn, Acacia, 
Willow, Elm, Sycamore, Fir, Walnut, Pear, Crab, 
Service, and Ash. On each of these I propose to 
make a few remarks. 
Apple. —By general consent this stands immensely 
higher in frequency than any other tree. Syme gives 
it a percentage of twenty-five. The late Dr. Bull 
said that this figure must be raised, but as he lived 
in Herefordshire this would be accounted for. 
Poplar. —Syme gives this next, at twenty per 
cent., but says “ mostly black.” My personal 
observation indicates that except in the western and 
southern counties Mistleto is more common on this 
tree than on the Apple. It abounds on the Poplars 
on the banks of the Mole, in Surrey, and the upper 
Thames. In the North of France and Belgium, 
where the rivers and canals are bordered by Poplars, 
hardly a tree is without this parasite. 
Oak. —Syme only assigns one per cent, to this tree. 
Dr. Bull says he could only find seven cases. Johns 
and the " Edinburgh Cyclopaedia ” say “ exceedingly 
rare.” Others say "occasionally,” and others omit 
it altogether. 
Lime. —Syme gives four per cent, for this tree, and 
it is generally included in lists. 
Maple. —Syme says three per cent, in this case, 
and it is only mentioned by two other authorities. 
Willow. —Syme gives two per cent, for this genus, 
which is mentioned by one other authority. 
Acacia. —Syme gives one per cent., ard Brown 
gives an instance in Ealing. Dr. Bull says the per¬ 
centage should be higher. It is included by the 
" Edinburgh Cyclopaedia.” 
Thorn. —According to Syme the percentage on the 
White Thorn is ten. Dr. Hogg names it, and Johns 
says " not unfrequent.” It is also included by the 
“Edinburgh Cyclopaedia.” A letter from Mr. 
Perkins, the head gardener at Greenlands, Henley- 
on-Thames, informs me that the Mistleto grows on 
Thorn trees on that estate. It also grows on the 
White Thorn at Dropmore, Bucks. 
Elm.— For this I have two authorities among our 
members, but it is only mentioned by Dr. Hogg. It 
appears to be confined to the Wych Elm. 
Sycamore. —Syme gives one per cent, to this. I 
have one authority among our members, and another 
in the " Edinburgh Cyclopaedia.” 
Fir. —Two authorities respectively say "occasion¬ 
ally ” and " sometimes ” it is found on this tree. 
Walnut. —Two authorities name this as a host 
plant. 
Crab. —Only one of our members mentioned a 
case on this tree. 
Service. —The " Edinburgh Cyclopaedia ” records 
this. 
Ash. — The sole authority I find for this is Johns. 
Pear. — None of our gardening members had ever 
seen an instance of Mistleto on the Pear, but it is 
named by Dr. Hogg as "occasionally,” and by the 
" Edinburgh Cyclopaedia.” 
Gooseberry. —For this I have the single authority 
of one of our members, and I have no reason to doubt 
his accuracy. 
With regard to its propagation the " Gardeners’ 
Dictionary ” says that “it will grow with difficulty 
on the Oak, but it readily takes upon the Apple, 
Pear, Poplar, and Willow.” 
Since writing the above my attention has been 
called to an article on" The Various Host Plants for 
Mistleto ” in The Gardening World for January 
nth, and this rather extends the list, as it includes 
the Rose, White Beam, Aspen, and Birch; and in 
exotic trees, the Red Maple, Chestnut, and Magnolia 
glauca. 
I trust that if any of your readers can add to the 
above list they will do so.—S. Arthur Sewell, 62, 
Ranelagh Road, Ealing.

MOVABLE GLASS ROOFS. 
In establishments where the glass department is of 
any size, the annual cost of repairing breakages, 
painting, etc., is a serious item in the bill of expendi¬ 
ture for the year. Hence any scheme which would 
materially reduce the working expenses should 
recommend itself very favourably to the notice of 
owners or managers of such establishments. A 
system of glazing recently brought forward by Mr. 
H. Becker, F'.R.H.S., cf Jersey, possesses material 
advantages over the one generally in use, and is 
especially suitable for nurserymen and market 
growers of all kinds. Instead of the ordinary rabbets 
and sash bars, strips of galvanised metal are 
employed, these being tightened as required by means 
of bolts and screws. Briefly, the advantages claimed 
for the invention are as follows Material reduction 
in the first cost of erection of the house or houses ; 
no necessity for outside painting and great facilities 
for glazing or unglazing ; also for any repairing that 
that may be required. These are all combined with 
lightness, durability, and more than ordinary rigidity 
and strength. This idea has been the outcome of 
Mr. Becker’s practical experiences as a grower for 
market, and will doubtless meet with an appreciative 
reception by the trade generally. 
CISSUS DISCOLOR, 
As a climber for the back walls of a stove it would 
be hard indeed to beat this well-known plant, either 
for beauty or effectiveness. Its culture, too, is very 
simple. All it seems to want is plenty of heat and 
an abundance of moisture, both in the atmosphere 
and at the root. A brisk bottom heat it fairly revels 
in, and it is astonishing to see the length and strength 
of the shoots produced by plants growing in borders 
traversed by, or in close proximity to, the hot water 
pipes. The present time is a very favourable one to 
conduct propagation if required. There are two 
ways of doing this. The first is to insert as cuttings 
the tops of some of the weaker shoots that have been 
cut from the old plants during their annual pruning. 
The second, and rather the surer method, is to wait 
until the young growths are a couple of inches or so 
in length, and then to cut them off with a h6el. The 
soil used for such cuttings should consist very largely 
of sand—in fact, they will root very readily in pure 
sand. A good bottom heat of not less than 8o° Fabr., 
with an overhead temperature of about 70° will insure 
a quick and successful ” strike.” In all cases the 
cuttings should be covered with bell-glasses. The 
soil at the first potting may consist of two parts of 
peat to one of loam, with, of course, plenty of sharp 
sand, but when the plants are established the compost 
may be r-ather heavier—say equal parts of peat and 
loam. Manure-water during the summer season, 
when the plants are growing freely, will be of 
advantage, but should not be given through the 
winter and early spring months. 
CHRYSANTHEMUM L. CANNING. 
This very beautiful variety, which is possibly the 
very best late-flowering white Chrysanthemum there 
is, ought to be extensively grown by all who are 
called upon for a supply of choice flowers during the 
declining days of the old year and the early part of 
the new one. It is not a new variety, but we think 
not so well known as its merits would lead one to 
expect. It is just one of those good things which 
hardly come up to the requirements of exhibitors 
and so is seldom seen on the show tables. At the 
same time, as it is almost invaluable to those who 
have to cater for the taste for cut flowers, it may be 
well to draw attention to the best method of growing 
it, because it is not amenable to the methods of 
treatment pursued for the production of show 
flowers, but does best grown naturally in bush form, 
With high culture it produces an abundance of 
beautiful white flowers of fair size, and that at a 
time when most valuable, it being naturally a late 
variety. From a batch of cuttings put in late last 
February, quantities of blooms were gathered the 
second week of the present month.— TV. B. G. 
SOCIETIES. 
Royal Horticultural. March 10th .—The meeting on 
Tuesday last was one of the fullest in more respects 
than one. Orchids were very extensively represented, 
there being five very large groups. Cyclamens, blue 
Primroses, Daffodils, Cinerarias, and various other 
stove, greenhouse, and hardy plants made up a great 
display. A large and showy group was set up by 
Messrs. J. Veitch & Sons, Chelsea. Very well done 
were Laelia cinnabarina, Odontoglossum Edwardi, 
Anguloa alba magna, Cymbidium lowianum, C. 
eburneo-lowianum, Dendrobium dalhouseianum, D. 
atroviolaceum, D. splendidissimum grandiflorum,

Phaius Cooksoni, P. Marthae, and P. amabilis were 
all very beautiful hybrids. Angraecum Humboldtii 
and A. sesquipedale were two very interesting kinds. 
Coelogyne cristata alba and several other kinds were 
well done (Silver Banksian Medal). 
A large and effective group of Dendrobiums was 
exhibited by T. Statter, Esq. (gardener, Mr. R. 
Johnson), Stand Hall, Manchester. Very con¬ 
spicuous were four large plants of D. nobile nobilius, 
also D. Rolfae, D. nobile Amesiae, D splendidissi¬ 
mum, and several others, all well flowered (Silver 
Flora Medal). 
Mr. James Cypher, Cheltenham, staged a showy 
group of Dendrobiums, including D. Ainsworthii 
Cypher’s variety, and D. nobile Cypher!. Very fine 
were Epidendrum xanthinum, E. O'Brienianum, 
and Odontoglossum blandum (Silver Banksian 
Medal). 
A large group of Orchids, set up with Ferns, was 
exhibited by Sir Trevor Lawrence, Bart, (grower, 
Mr. W. H. White), Burford Lodge, Dorking. He 
was awarded a Cultural Commendation for a large, 
well-flowered piece of Laelia lindleyana. Very fine 
also were Odontoglossum crispum pardalinum, 
Cypripedium rothschildianum, Dendrobium cruen- 
tum, and others (Silver Flora Medal). 
A group of Orchids was staged by W. Vanner, 
Esq. (gardener, Mr. W. H. Robbie), Camden Wood, 
Chislehurst, consisting of Cattleyas, Dendrobiums, 
Calanthes, etc. (Silver Banksian Medal). A Cultural 
Commendation was awarded to Welbore Stuart 
Ellis, Esq. (gardener, Mr. D. Masterton), Hazel- 
bourne, Dorking, for a large pan of Coelogyne 
cristata alba. A similar award was made to Sir F. 
Wigan (grower, Mr. W. H. Young), Clare Lawn, 
East Sheen, for a fine piece of Miltonia Roezlii 
splendens. Cattleya Trianaei crawshayana was 
shown by De B. Crawshay, Esq. (gardener, Mr. S. 
Cooke), Rosefield, Sevenoaks. 
Calanthe Baron Schroder, Odontoglossum 
crispum Rex, O. coronarium brevifolium, Oncidium 
brunleesianum, and several other fine things in 
excellent form were shown by Baron Schroder 
(gardener, Mr. H. Ballantine), The Dell, Egham 
(Silver Banksian Medal). Charles Winn, Esq. 
(gardener, Mr. T. Armstrong), Selly Hill, Birming¬ 
ham, exhibited Dendrobium Othello, D. Hebe, D. 
Aspasia, D. Joan, Cattleya Trianaei Upland var. 
etc. (Silver Banksian Medal). 
Cypripedium Wottoni, a very fine hybrid, was 
exhibited by R. I. Measures, Esq. (gardener, Mr. H.

drobium Cassiope virginalis and other interesting 
hybrids were shown by N. C. Cookson, Esq., 
Oakwood, Wylam-on-Tyne. Cypripedium harrisia- 
num virescens was shown by M. A. A. Peeters, St 
Gilles, Brussels. 
A large group of forced plants was set up near the 
doorway in very effective style by Messrs. Wm. 
Cutbush & Son, HighgateNurseries, N. It included 
Staphyleas, Acacias, Azaleas, Boronias, Daphnes,
