THE GAR DEN/NO WORLD. 
September 3, 1904. 
would serve to keep the plants clean and healthy, and in Pro¬ 
portion as the bottom is water-tight, so the less water will be 
necessary to cause this gentle current. Put on two or three 
inches of good soil over the clay, in which the Watercress! may 
take root and grow. The soil in turn might with advantage be 
covered with a layer of clean gravel, which will keep the soil in 
place, and thus be more easily kept clean, though the gravel is 
not an actual necessity. Before turning on the water, it would 
be well to have Watercress plants ready, so that you can plant 
them all over the bed in well-established plants obtained from 
some other isouroe or by raising them from seeds. 
Cabbages and Cauliflower for Seed. 
I want to grow seeds of various things on a. piece of ground 
here, 'but have been told I should not attempt Cabbages an 
Cauliflowers so close together. I should be much obliged for 
your opinion of the case. (R. J. H.) 
We (should not attempt to- grow those two' kinds oi Crucifers 
on the same field, unless it was a very large one. Both are iorms 
of the common wild Cabbage, selected and developed by man ; 
consequently, they are liable at any tame to be intercrossed by 
bees if flowering at the same time anywhere m the neighboui- 
hood of one another. On the other hand, you should grow a 
larger quantity of one kind rather than smaller lots ot two or 
more of the Brassica family in the same field. By the term Bras- 
sica we should imply Brussels Sprouts, Broccoli, Kale®, and even 
Turnips, as being unsafe to grow for seed in the same held, xou 
could, of course, grow varieties belonging to quite ddterent 
families of plants for seed purposes even on a smad held, because 
the flowers would not intercross with one another. Instances; ot 
what we mean are Wallflowers, Godetias, Mignonette, Nemoplula, 
Lupins, or such other tilings, as you might find it possible >,o 
grow with profit on your soil, and with the climatic conditions ot 
the district. 
Propagating Aralia japonica. 
A lar"e specimen of Aralia japonica. planted out about xoui 
years ago shows that it is quite hardy here, and, as it- flowered 
last- autumn, we should like to raise a good number for planting 
in various parts of the grounds to give colour in autumn. Can 
cuttings he rooted easily, or is there any quicker way of getting 
stock? (S. G.) . . -. 
Cuttings of this plant can he rooted, but it would not prove a 
quick method of increasing the plant, for the simple reason that 
even a 1 arga plant would only supply a small number of crowns 
of which to make cuttings. A better plan would be to get seeds 
from some of the leading seedsmen, and sow them in pot® of 
sandy soil in February or March next in. heat. After they have 
germinated, they could be gradually hardened off and transferred 
to frames. As soon as large enough, they could be potted oft 
singly or planted out in soil in cold frames-, where they would 
sooner attain some size than in pots. If you get good seed 
there should be no difficulty in quickly raising a stock in this 
way though it would take years before you could flower them. 
diseased 
The stems and leaves of our Mint are very much crippled. 
The leaves are small, and the stems twisted and swollen m 
places, being covered with something like rust of Chrysanthe¬ 
mums. What would you advise to get rid of it? (T. R. M.) 
Your plants are no dbubt attacked with the Uredo labiatarum, 
or rust of Mint. It does not, as a rule, spread with such rapidity- 
as the rust of Chrysanthemums, nor do so much damage. It 
vreatly depends upon the situation in which the Mint is grown. 
In a moist place and if much sheltered by the surroundings the 
furious will make more rapid growth than if the plants-were m 
a more exposed position, where light and air could get to them 
more freely. Your best plan to get rid of it would be to take 
cuttinos of -clean shoots, root them in a cold frame, and then 
make a fresh plantation at some little distance from the present 
one 4s the fungus lives inside the stems, it is not always 
possible to tell whether the cuttings you take are actually clean 
or not. Another chance would be to dig up the roots of the 
plant in spring and select the clean underground stem®, cutting 
them up in suitable lengths with roots attached, if possible, and 
make a fresh plantation with these. As a rule, this would be 
sufficient to enable you to get plenty of healthy clean leaves 
for use. If you keep an eye upon the fresh plantation and 
carefully dm up every specimen as soon as it shows having been 
attacked by°the fungus, you will thus assist its progress before 
it has scattered fres-h spores to attack the remaining plants. 
A little watchfulness on your part in the early stages will save 
a deal of trouble and enable you to get a clean stock.
