are quite hollow. As the shoots will be killed anyhow, you should 
take a close basket or some other vessel and go over the bushes, 
cutting off all the shoots that show drooping leaves. After having 
made the cut make sure that the whole of the burrow has been 
removed while the contained grub is still present. You can 
examine the shoots for yourself, and be convinced that this is 
the case or otherwise. If the caterpillar is present you will have 
no difficulty in making out the cause. All these shoots should 
be burnt, and you must make it a custom to- burn all the 
primings of the Currants in autumn. By that means you will 
destroy any caterpillars that may be in them. 
Plague of Slugs. 
The ravages of this pest at present are extremely annoying when 
we are busy trying to establish Cauliflowers and others of this 
class. Is there any quicker method than hand-picking to keep 
the pest in check P (R. M.) 
It is a very good plan to lay down little heaps of bran in the 
neighbourhood of the plants to be protected. The slugs wil-1 find 
out"this in large numbers, and by going round in the evening 
or early morning you will find the depredators about and in the 
neighbourhood of the traps. You can also take special means to 
protect any valuable crops of Cauliflowers or others of the Cab¬ 
bage tribe. Some years ago earthenware cylinders were specially 
made for placing round young plants of this character to protect, 
them from slugs. Others employ cylinders of zinc or tin, about 
6 in or 8 in. in depth. One cylinder is placed round each plant, 
and this the slugs are unable to climb. After the plant has made 
some growth they get hardened, and are tlien safe from these 
pasts, when the cylinders may he employed for other plants. See 
also, in another column, articles upon keeping down slugs, both 
m this and in previous numbers. 
Ants Under Grating. 
One of our plant houses is very much! infested with a black 
ant, which has its headquarters somewhere under the grating 
about the hot water pipes. Tlhey do not seem to do much harm 
beyond keeping the plants dirty by finding out scale and encou¬ 
raging them. I have been told they carry the scale about and 
use them as cows. Is there any better method of destroying 
them than having strong-smelling liquid standing about the house 
in jars? (T. W. W.) ... 
Carbolic ac-id has been used with great effect in driving them 
away, and we think this would be preferable to the use of paraffin, 
which has also been used. Both- of these ingredients smell 
rather strongly, but the smell of carbolic acid is by no means dis¬ 
agreeable, while it would become dissipated sooner than paraffin. 
Paraffin about hot-houses and in borders is disagreeable, and un¬ 
desirable on account of its oily character. The carbolic acid 
should be diluted in 12 times its bulk of water, and sprinkled 
into the ruus of the ants. They dislike the smell of it, and 
leave their quarters for some other locality. 
Double Yellow Wallflowers. 
We have some double yellow Wallflowers, but they do not pro¬ 
duce any seed, and are now getting leggy ; young plant's would 
look better. Would it he possible to layer them the same as Car¬ 
nations? Any information would oblige. (Wallflower.) 
Some double yellow varieties do- not produce seed, notably 
Harpur-Crewe. Your plants might be. layered, but we fear they 
would be brittle, and liable to snap off when you are bending 
them down. A better plan would be to take cuttings of the young 
shoots when getting firm. See also another article on double 
Wallflowers.
