been the case with the others) by preventing the natural flow of the 
sap; I may say that the subsoil here is in some parts gravel, and in 
others blue lias clay. The trees were planted over both, and were all 
grafted just above the ground. Six years ago it was thought that if we 
had trees on their own roots they might not be subject to the disease, 
accordingly some good nuts were gathered from the best of the trees, and 
a number of seedlings were raised. Most of them have flowered this sea¬ 
son. Of the flowers some are inferior, others equal, and others superior 
to those of the parent. The ordinary white-flowered Horse Chestnut is 
quite free from any disease, as are also the Pavias.” The specimens 
were forwarded to Prof. H. Marshall Ward for examination and report. 
Asparagus Fasciated, —Mr. Kitchen of Hampton sent a specimen of 
following spring the fungus began to appear on a leaf here and there in 
my collection, and for twelve months it was continually cropping up. 
I have seen no trace of it now for a long time, and doubtless the drastic 
measures 1 adopted thus quickly stamped out the disease. My clothes 
in this case must have been the medium by which infection was carried 
to the plants. 
1 entertain the fear that composts in which manure forms a part is 
responsible for the attacks of nematoid worms, which, even when con¬ 
fined to the foliage only, are capable of doing much harm. On that 
account I am careful to incorporate no manure in the soil for “ Mal- 
maison ” Carnations. The plants grow well without manure, provided 
some manurial agent is watered into the soil as required, It is possible

this extremely common phenomenon, with the end spirally twisted into 
a helix. 
Polygonum Leaves Marked by Frost. —Mr. Henslow showed leaves 
received from Wiltshire, having two colourless longitudinal bands. 
Every leaf on the tree was said to be similarly marked. It was attri¬ 
buted to the frost catching the young leaves just where they were 
exposed on unfolding. 
DISEASED CARNATIONS. 
Those persons who are troubled with disease on the foliage of 
“ Malmaisons ” and on other Carnations ought not to be discouraged on 
that account. I do not here refer to Helminthosporium, of which I 
know very little ; but my experience of it may be of value to others. A 
gentleman in the south of England kindly sent me examples of foliage 
infected with this fungus, which, after examining, I burnt. The 
that the above may be responsible for more mischief than your corre¬ 
spondents imagine. Besides this leaf disease and somewhat like it in 
general appearance there is a very common form, which is initiated by 
unsuitable treatment. The first-named attacks the lower parts of the 
leaf, the latter the tips. The only palliative in either case is to remove 
the leaf, or the affected part of the leaf, as the case may require, when 
afterwards, by means of good treatment, the plants may outgrow the evil. 
Only perfectly healthy shoots, and these not too large, ought to 
be layered for stock. I am cognisant of several cases where unhealthy 
plants have been treated so as to produce a healthy stock. A collection 
I saw last year was composed of large plants, which the year previous 
had been badly affected, but which, by the removal of infected foliage 
and keeping only healthy shoots on the plants, had recovered, and were 
in such vigour as to produce splendid blooms later in the season. In 
Scotland we find that “Malmaisons” cultivated entirely under glass 
appreciate a little shade from sun. With me aphis is more troublesome
