and in such a position they will become firm, 
matured early, and consequently well prepared for 
early forcing. We have had a number of such forced 
shrubs turned out of their pots into rather firm 
ground, where they will remain till the forcing sea¬ 
son begins, when they will be lifted and potted up 
firmly. It is an extravagant practice to throw away 
the stock of forcing shrubs every season as soon as 
they have yielded their crop of flowers.— Stirling. 
extent and flower poorly or not at all. There are 
many cultivators who take great trouble with it, yet 
obtain very unsatisfactory results. Others, however, 
succeed in establishing it, and are handsomely re¬ 
warded for their trouble, as maybe seen by reference 
to the accompanying illustration of the porch of the 
Sanatorium at Harrow School. 
Some growers use peat as a medium by which to 
keep the fleshy tuberous roots cool and moist, and 
and known amongst botanists as Tropacolum 
speciosum. In far off and bleak Caithness it seems 
equally at home, so that its hardiness is thoroughly 
established, and the facts concerning its behaviour in 
this country would point to the atmospheric condi¬ 
tions as governing its success or failure. 
Those who attempt its culture in the south should 
choose a cool and moist position for it, although not 
a position where stagnant moisture exists, otherwi s

TROP/EOLUM SPECIOSUM 
There are few who have seen this hardy Tropaeolum 
in characteristic condition but would like to try it in 
their gardens if they have any. It is a native of 
Chili, and seems to inherit the cooler and moister 
portions of that country judging from its behaviour 
in this. In the drier and more sunny south of Eng¬ 
land it is very difficult to establish, and although it 
may take hold of the soil and send up shoots here 
and there or sometimes plentifully, yet the said 
shoots in many cases refuse to elongate to any great 
are thus able to get a considerable amount of growth 
if the plant does not flower. It is quite different in 
the north, where it may be planted anywhere and in 
any exposure with equally successful results. The 
fronts of many cottages and the sunny exposures of 
railway sidings in Aberdeenshire are wreathed and 
adorned with its flaming tresses in the same way 
as cottages in old-fashioned villages used to be 
adorned with the hedge Convolvulus (Convolvulus 
sepium). The front of a hotel at the foot of Ben Nevis 
also presents a sight that would charm would-be 
growers of this plant, improperly termed Nasturtium, 
the fleshy rhizomes would be liable to rot. Peat or 
leaf soil may be used to ameliorate the staple and 
moisture holding power of the natural soil. A few 
twiggy stakes or a trellis may be used by which it 
may support itself by means of its twisting petioles. 
We do not know that any cultivators have tried the 
effect of standing some earthenware pans filled with 
water about the foot of the stems in order to ensure 
atmospheric moisture, but it might be worth while 
making the experiment. The pans should be hidden 
and made as unobtrusive as possible, and kept filled 
from time to time.
