THE GARDENING WORLD. 
(Jnditions a temperature of 35 degrees to 
decrees should be maintained, the lat- 
r when the weather is naturally warm 
; d the ventilators open. If the trees 
;2 the only occupants of the house, a 
title frosty air will not injure them. 
b) Spring Temperature. — We are now 
caling with the trees after the house is 
osed°for forcing purposes. But I must 
once say do not maintain a high for- 
,icr temperature, simply close the house 
, cf keep the pipes warm night and day 
.til the young shoots are about half an 
:h long. A minimum of 42 degrees 
d a maximum of 55 degrees will be 
fficient for ordinary forcing. 
(c) Summer Temperature. — Artificial 
;at will not be needed after the end of 
e first week in June unless the weather 
cold and sunless and ripe fruits are 
qutred for a special purpose. In such 
xumstances it would be necessary to 
ofitlv warm the pipes at sunset and 
low "them to cool about 10 o'clock the 
morning. As soon as the fruits are 
t and are about the size of small Barce- 
na nuts, thoroughly syringe the trees 
closing time, about 2.30 p.m. in spring 
>d 3.30 p m. in summer, and allow the 
•at to rise to 75 degrees or 80 degrees, 
ider the influence of the sun. These 
mperatures will suit the trees both when 
e fruits are set and also when they are 
.elling after the stoning period. \ enti¬ 
re early in the morning, first open the 
p ventilators a little, then wider as the 
.n gains poiver, and towards noon open 
e front ventilators a few inches only, 
lose the front ones first and the top 
les last, being guided in doing so by 
e condition of the weather, 
sbudding the Shoots. 
In doing this w-ork it should be borne 
mind that the new shoots which grow 
.is year will bear fruit next year, and 
.at the thorough ripening of the new 
nod is essential. To secure maturity 
: wood, the shoots must be so disposed 
iat overcrowding does not occur. A 
stance of at least three inches between 
ich young branch is necessary, but four 
iches would be better. The branches 
pon which the fruit is borne this year 
d not count as regards the laying-in of 
le young shoots. 
There may be from a dozen to twenty 
oung buds on a branch 18 inches long. 
: would not do to allow all these to grow, 
lerefore commence to remove, or dis- 
ud. them as soon as they are large 
nough to handle. Rub off a few each 
ay for a week until all are taken off but 
hree, ohe at the base, one near the 
ientre, and one at the end of the branch. 
,f the branch is only 12 inches long, two 
oung shoots are sufficient to leave on, 
jamely, one at the base and one at the 
jnd. Retain the best-placed shoots, those 
hich grow' on the top side of the branch,

— SINGLE — 
Chrysanthemum 
MRS. HAZELHURST. 
At the present time yellow and bronze 
varieties of Chrysanthemums are very 
popular for decorative work in the home 
and at exhibitions. The variety under 
notice, although not exactly either of 
these colours, belongs more to the bronze 
than the other shade. The rays may be 
described as chestnut-red when they first 
expand, fading to a salmon-red when 
fully developed. The variety would be¬ 
long to the large flowered section of 
single Chrysanthemums, as the blooms 
measure 3 in. to 4 in. in diameter when 
only slightly disbudded, so as to leave 
each flower single at the end of the 
shoots. As the variety branches freely, 
and each branch or shoot termirfates in 
a number of flowers, a well-grown plant 
produces a large number. 
The accompanying illustration Shows 
quite a small branch bearing a number 
of flowers, all of the blooms being at¬ 
tached to one short stalk. This will give 
an idea of the floriferous character of this 
new variety, which is being put into com¬ 
merce by Messrs. \Y. Wells and-Co. , Ltd., 
Merstham, Surrey, who have been instru¬ 
mental in putting a large number of very 
choice single varieties into commerce. A 
large proportion of the single varieties 
are perfectly capable of standing the "win¬ 
ter in the open ground in the south of 
England, so that people with little or no 
glass might grow' large numbers of such 
Chrysanthemums for turnishing cut- 
flowers during the autumn months. 
Polystichum aculeatum gracillimum Druerv. 
. The above is an extremely handsome 
and distinct Fern raised from P. a. pul- 
cherrimum, which w'as discovered about 
thirty-five years ago. About four years 
ago this plant gave rise to a few- spores 
for the first time, and they were, of course, 
sown by the ow-ner, Air. C. T. Druerr, 
V.M.H:, 11, SLaa Road, Acton, London. 
Of the, sporelings that germinated 75 per 
cent, represented the parent form, and 
20 per cent, w'ere like the new variety, 
P. a. gracillimum. The remaining 5 per 
cent, showed a reversion towards the 
original wild species. A plant about 
four years old was shown at a meeting 
of the R.H.S. on November 24th, when 
it received a First-class Certificate. The 
fronds are bipinnate, and the pinnules 
are narrowly linear with long, needle¬ 
like incised teeth at distant intervals 
along the sides. These pinnules are ex¬ 
tremely narrow, and vary from \ in. to 
2 in. in length, giving the Fern a very 
handsome appearance.
