manure year after, year, so that it is now

f v i ne vegetable matter, to produce a good 
L Sf Potatos. The best plan would be 
trench it, and in spring give it a good 
essing of lime, merely pointing it into 
e top soil. We do not think the worms 
ve anything to do with the lack of crop, 
•jev are merely present because there is 
en'ty of food for them. You may, if you 
use an artificial manure next year, but 
rmyard manure should not be used. An- 
her kind of crop for a year or two would 
ve the soil a rest from Potatos.

A Selection of 
- Useful Climbers. - 
Occasionally the question is asked, 
what, plants are suitable for covering 
poles, pergolas, arches, stumps of old 
trees, rough walls, rustic arbors, and 
similar objects. While recognising the 
value of Roses, I shall intentionally leave 
them out of consideration, and confine my 
remarks to other subjects which are not 
grown in such quantity, but at the same 
time are, perhaps, quite as fascinating to 
the average plantsman if not to the Rose 
specialist. 
The varieties of Clematis are almost 
legion, but the one I chiefly recommend 
here is C. montana rubens. Its rosy red 
flowers are produced twice in the season, 
and the stems and leaf stalks are of a 
reddish purple hue. Another is C. 
davidiana, which has light blue flowers. 
Then there is the Jackmanni section, 
while the old C. Yitalba (Travellers Joy) 
is not to be despised. 
Polygonum multiflorum is an ideal 
plant for covering trellises,, etc., being 
free growing and free flowering, if not 
o-iven too generous treatment. A sunny 
position suits it best, and beyond a clip 
over sometimes to keep it within bounds, 
nothing more is needed. Then we have 
P. baldschuanicum, a magnificent ex¬ 
ample of floriferousness, every branchlet 
terminating in. a panicle of small white 
blossoms. To secure the finest results 
prune close into main stem in March. 
The species of Vitis, of which we have 
such a wide selection, are indispensable. 
Their bold foliage, quick growth, and 
beautiful autumn tints render them at 
once valuable acquisitions. 
Among those of the first water is V. 
armata Yeitchii. The leaves are large 
and heart-shaped, and when young the 
colour is a bronzy green, but in the 
autumn they assume a reddish hue. V . 
Thompsoni will become very popular tor 
it is indeed a useful climber, and has 
purple foliage and stems, which change 
to deep purplish red later in the season. 
Others are V. heterophylla, Y . Coigne- 
tiae, and V. Thunbergii. 
The Honeysuckles are always admired 
for their delicious fragrance, and the 
varieties known as late and early Duich 
and Lonicera japonica are recommended. 
A further list would embrace Passiflora 
caerulea, Actinidia chinensis (somewhat 
resembling a Vine), Wistaria chmensis, 
the Ivy, etc. 
Ordinary good garden soil is sufficient, 
and when employing poles, and other sup¬ 
ports, secure the strongest available, 
while they should be examined 
periodically to prevent disaster during 
high winds.

TRADE NOTICE, 
W. Cooper’s Catalogue. 
We are in receipt of the illustrated 
catalogue of Messrs. William Cooper, 
Ltd., Horticultural Providers, 761, Old 
Kent Road, London, S.E. It runs to 
416 pages, and is well illustrated through¬ 
out with all sorts of buildings which 
would be useful for gardens, for poultry, 
pigeon houses, chickens, golf pavilions, 
billiard rooms, rustic vases, garden seats, 
etc. Very numerous types of conserva¬ 
tories are illustrated, together with speci¬ 
fications and costs. Those wishing to 
have houses of any sort built would find 
this catalogue a very useful guide, both 
as to dimensions and technical terms in 
connection with the various buildings. 
Wall fruit protectors in variety are also 
shown, and what would prove a pleasing 
change to many residential villas, win¬ 
dow conservatories, which are built on 
the outside of .windows, thus affording 
shelter both to the plants and to the 
people inside, who can inspect the plants 
at any time without inconvenience.

Electricity as a Stimulant to Plant Growth. 
Writing on this subject in “ Electrical 
Engineering,’’ the editor refers to a re¬ 
cent communication in that journal from 
Sir Oliver Lodge, which calls attention to 
the fact that the application of electricity 
as an aid to agriculture has passed be¬ 
yond the stage of a scientific experiment, 
and has reached a point where useful 
commercial results are obtainable. He 
describes Mr. Newmans large scale ex¬ 
periments carried out under practical 
working conditions. The installation 
amounts to very little more than the 
erection of a network of wires over the 
field at a height at which they will not 
be disturbed, and arrangements for keep¬ 
ing these wires continuously charged at a 
high electrical pressure. The pole-work, 
etc., is of a simple character, and, al¬ 
though the electrical generating ma¬ 
chinery and its accessories are of necessity 
more complicated, when it is once fitted 
the subsequent supervision and mainten¬ 
ance is a comparatively small matter.
