with the result that they never regain 
their natural appearance and remain a 
disfigurement to the border for the rest 
of the season. For the moie slender sub¬ 
jects hazel twigs will 'Suffice, and in time 
will be completely hidden by the foliage. 
The border should be trenched and 
manured every second or third year, and 
the stronger-growing plants lifted and di¬ 
vided, otherwise they will encroach and 
over-run their weaker neighbours. Sucn 
subjects as Tree Paeonies and Tritomas 
are impatient of disturbance at the root, 
and these should not be disturbed in the 
course of the work.

Which are the Best . . 
PEAS ? 
Having to keep up a large supply of 
green Peas for as long a season as pos¬ 
sible, I have had to make a very careful 
study of the many varieties on the market 
so as to be able to secure heavy cropping 
and first-rate table quality. As most 
gardeners are aware, the heaviest crop¬ 
pers too often produce seeds of very poor 
flavour, and although the fine crop is very 
gratifying to the grower, the grumbles of 
:he consumer more than counterbalances 
any satisfaction felt at the big crop. 
After very exhaustive trials of most of the 
varieties "offered in the seedsmen’s cata¬ 
logues, I have now been able to select a 
aalf-dozen or so distinct kinds that have 
for several years given most satisfactory 
returns in this garden. Our soil is a 
heavy loam and the district cold and late. 
For the earliest sowing nothing can equal 
• The Pilot,” an Irish-raised sort. Gradus 
does fairly well, but is a very light crop¬ 
per, and I am looking for a better second 
early. Edwin Beckett I think better 
:han Gradus, but it, too, hardly gives as 
heavy a crop as I could wish. Boston 
Unrivalled comes next, and is probably 
the finest Pea we have among the second 
earlies or maincrops. Then Alderman is 
a good succession to the last-named, and 
is followed by Glory of Devon, Royal 
Salute, and The Gladstone. Carter’s 
Daisy is by far the best dwarf Pea, and 
several sowings of this variety can be 
made, and will produce more Peas on a 
I given space than any other kind I know 
af. For a late, cold district, I would 
therefore say that the best six Peas are :• 
The Pilot, Boston Unrivalled, .Daisy, 
Glory of Devon, Royal Salute, and The 
'Gladstone.

Fruit Trees and Pollination. 
Every orchard should also be an apiary. 
In a recent report of the Woburn experi¬ 
mental fruit farm it is pointed out that 
a continued spell of cold weather may act 
indirectly by lessening the activity of the 
various insects which effect pollination. 
The obvious remedy would be for fruit¬ 
growers to go in more largely for bee¬ 
keeping. 
Jackman's Clematis 
AyyCG (Clematis Jackmani). 
Of all the hybrid types of Clematis, 
none is more popular or so easily man¬ 
aged as C. Jackmani. Some people want 
to prune their Clematis when they get 
too bulky, as they usually do after having 
got established for a year or two. This 
has to be done with a knowledge of the 
plants operated upon, because several of 
the types bloom only upon the wood made 
during the previous year. C. Jackmani, 
on the other hand, flowers on the wood 
during the current year. In northern 
countries a large portion of the wood gets 
killed down in autumn, but this does not 
trouble the cultivator, as it saves him a 
deal of trouble in trying to unravel shoots 
that are usually intricately twisted one 
with the other. 
The simplest process is to cut the plant 
down after it has been injured by frost 
to within 12 in. or so" of the ground. 
Next spring numerous strong buds will 
arise from the crown of the plant, and 
the cultivator, if at all in love with his 
subject, will give the plant weekly at¬ 
tention for a while for the purpose of giv¬ 
ing it a tie here and there to make sure 
that the various shoots are distributed in 
the proper direction, so that no crowding 
will take place and that all parts of the 
support to be covered will have stems 
evenly distributed upon it. This, there¬ 
fore, is one of the easiest methods of deal¬ 
ing with a climbing Clematis, because 
sooner or later the stems are sure to get 
interlaced with one another, and it is ex¬ 
tremely difficult to separate them, while 
it is almost impossible in winter to tell 
whether all the stems are alive or some 
of them may be dead. 
This popular form originated as a 
hybrid between the Chinese C. lanuginosa 
and the European C. Viticella, which 
may be compared to our own C. Vitalba, 
except in the colour of the flowers. The 
flowers of C. Jackmani usually consist of 
Clematis Jackmani.
