Carboline for Hot-Water Pipes. (A. Donaldson.) 
We have been making inquiries concerning Carboline, and 
one correspondent replies that he believes Stemocarbol to be 
the same thing. He thinks if hot-water pipes were painted, 
with it, it would not give off injurious fumes. Stemocarbol is 
described as the best antiseptic varnish for the preservation of 
woodwork of every description. It is an efficient counter ^f ' 
to atmospheric influences, such as moisture and noxious 
vapours or gases. It is stated also to be the best-known cor¬ 
rective for damp walls. Bricks or stones, when coated wit.i 
it are said to be rendered hard and impenetrable It seems 
to’ us, however, that not very much is known about its use toi 
the painting of hot-water pipes, but the makers are of opinion 
that it will not give off injurious fumes. 
Shrubs Dying after Transplanting. (J. H.) 
In dry seasons care should be taken to keep the roots of 
the lifted plants moist while they are out of the 
exposure cannot be avoided between the lifting and the plam- 
ino- it would be well to make up a thin mud with earth and 
water, and to puddle the roots in this. They take up a quantity 
of the mud, which forms a coat over the tender roots, and thus 
prevents them from getting dried up. During moist weather 
like what we have been having for some time past, unless a 
very dry day intervenes while the operation was being camec 
out this protection would scarcely seem necessary If such 
precautions were taken, it would act beneficially on the plants 
by keeping the roots moist until again placed in the soil, but 
this is more particularly necessary in dry seasons, while die 
soil is still in a dry condition when lifting-time arrives On 
such occasions the method of puddling the roots might well 
be borne in mind. 
Rose of Jericho. (T. G.) . . 
We do not believe that this cruciferous plant (Anastatica) 
will ever become green any more than any other plant afte 
has lost its leaves. The branches may spread out m watei, 
but the plant being an annual, and having completed its I f- 
cycle by the production of seeds, it will not grow any more 
If there are any seeds on the plant, these, when brought m 
contact with moisture, would be likely to germinate if, ail 
other conditions to growth are favourable, but the old plant 
itself will show no sign of life. The story about the plant 
spreading open is merely the moisture causing the biancies 
to spread out, but the plant is, of course, dead. 
Carnations Destroyed by Grubs. (A. M, T.) 
The grubs you mention are most likely those of the leaf le 
jackets/’ otherwise known as Daddy Longlegs, because, LUe 
eggs are deposited at such a time that they are ^ a J cl ^ d ^ 
aive rise to grubs at this season of the year. Most of them 
would be laid amongst grass m wet or marshy places. > ome- 
times, however, they may be laid at the roots of Carnations 
in the garden, and the grubs prove very troublesome by eating 
through the stems of any other herbs which may be growing 
there. One of the cures is to keep the beds clear of weeds^ so 
as not to encourage the presence of the flies amongst the Car¬ 
nations. If there is rank grass or other coarse herbage m 
the neighbourhood of the garden—that is. outside the wails 
or fence-end not eaten by cattle, it should be closely mown 
down or cut with the scythe, to prevent the harbouring tu 
this and similar insects. You should carefully examine the 
youna plants cf the Carnations, and pick off any grubs about 
the collar of the plants, destroying the same A little pow¬ 
dered lime scattered round about, but not on, the plants would 
help to keep the grubs away. 
Should Annuals be Left Thickly in the Autumn 1 (A. C.) 
If the seedlings are two or three inches apart, according to 
their kind, or, rather, the size of the leaves, that would cer¬ 
tainly be close enough for them to stand the winter. This 
would leave a sufficient number to make provision for accidents 
during the winter, so that in spring every alternate plant might 
be pulled out if necessary, to allow plenty of space for the 
development of the plants left. The distance apart will all 
depend upon the height the plants attain, and the spread of 
the branches. Your chief point will be to have them suffi¬ 
ciently thin that the leaves will only touch, and certainly not 
overlap, one another during the winter, because then they 
will keep better than if in any way crowded. 
Wistarias for Pot Work. (Guo.) 
We are quite aware that Wistarias attain a great height 
when planted out in the open ground, because, when once 
established, they make long rambling shoots. For pot work, 
however, they can be restrained within due bounds by grow¬ 
ing them in pots plunged in soil. This will restrict the roots, 
and even then, if the plants commence to throw out long ram¬ 
bling shoots they can be pinched in summer while growing, so 
as to encourage the development of spurs, which are short 
side-shoots that, when encouraged to plump up properly in 
summer, are almost sure to produce some fine racemes of 
blooms in spring. The long rambling shoots, if allowed to 
attain any length in summer, can be cut back before the plants 
are "placed indoors in spring, but a better plan would be to 
pinch them in the early stages, thereby preventing them from 
being formed. No lull’d forcing should be attempted, as cln- 
buds will very soon develop when placed in the ge'nial warmth 
of a greenhouse in March, or earlier if you care to.

Silver Leae Disease. —With reference to the report in the 
minutes of the last meeting. Professor Gaut wrote as follows : — 
“ I notice in this morning’s ‘ Gardeners’ Chronicle,’ p. 196, a 
slight error. It is this : ‘ Silver leaf was due to a lack of nitro-' 
gen in the soil.’ It should have been ‘presence of too much.’ 
I was quoting Dr. Massee. Mr. Bland, the owner of the fruit 
trees affected, before he wrote to me, sent some leaves to the 
Board of Agriculture, who sent them on to Dr. Massee. The 
following is a copy of the report: ‘Copy A, 3350.—Diseased 
Plum trees.—The disease is generally known as silver leaf, 
and lias been proved to be due to the presence of too much' 
nitrogenous food in the soil. Abstain from using farmyard or 
organic manure of any kind, and sow rape or some quickly-grow¬ 
ing crop under the trees. Remove the crop when fully grown.’ ” 
Much hesitation was shown by the committee in accepting this 
conclusion, as Portugal Laurels growing in poor, gravelly soil 
have been known to be badly affected, as much as garden fruit 
trees. 
Asparagus Diseased. —Herr Otto Froebel, Zurich V., sent the 
following communication, with specimens : “ Dear Sir,—Permit 
me to send you to-day by post a monstrosity I observed since 
last year on my old plant of Asparagus retrofractus. We call 
such form ‘ Hexenbesen,’ which means ‘ Witch’s broom.’ They 
are often observed on different hardy plants, on Conifers, 
trees, and shrubs. However, I have never observed this anomaly 
on any one of my various species of Asparagus, and I hope ii 
will be interesting to the readers of the Journal of the R.H.S., 
if you will bring this notice.” Mr. Michael undertook to examine
