GLENN Y ON THE CALCEOLARIA: 
the atmosphere ; and, if it be not so naturally, 
which is seldom the case, unless it be exposed 
to the sun in shallow vessels, it ought to be 
made so by putting a little warm water into 
the waterpot, so as to raise the tempera- 
ture a little. Water kept in a heated house 
vould do ; but tliere is no way so simple as to 
put a little heated water to the quantity you 
are using. Many plants suffer greatly from 
the chill given by pump and other cold water, 
when they are sending forth their young 
growth. 
SHADING. 
As the warm days advance, the full power 
of the sun would be injurious to the plants, 
and rapidly dry up and heat the soil in the 
pots. To prevent this, a thin or transparent 
cloth should be used, that will not exclude the 
light, but yet keep off the power of the sun ; 
as the plants however want air, the glasses 
should be propped up at all four corners with 
blocks of wood, or bricks, or flower-pots, or 
some other contrivance which will allow the 
air to pass freely over all the plants ; and the 
shading is only to be continued in the strongest 
heat of the day. At morning and evening, 
when the power is not great, they may have 
the benefit of it with the glasses off, until the 
period when the colour of the flowers begins to 
show, when they must be still more carefully 
protected against sun. 
TREATMENT TO THE TEME OF BLOOMING. 
In the spring, when the plants begin to grow 
the pots rapidly fill with roots, and it will be 
necessary to examine them, by turning out 
the balls of two or three occasionally, to see 
how far they may require shifting to larger 
pots, from 48's to 32's. The operation has 
to be performed in a manner precisely similar 
to that of the first shift from 60's to 48's, and 
they must be treated in all respects the same. 
In a comparatively short time even these will 
be filled with roots ; if the plants, from their 
size, require one shift more, the state of the 
roots must be examined as before recom- 
mended, and the shifting will be just the same 
as well as the treatment afterwards. As the 
stems rise for bloom they may require support, 
but proper habited plants will not, unless they 
are drawn up. If, however, for the purpose 
of travelling or for exhibition tying up be- 
comes necessary, it should be done with very 
slight twigs of osier, with the bark on, and 
as soon as the flowers begin to swell and take 
their places in their bunches : the twig should 
reach above the flowers and be tied loosely, 
for the stems would grow, and if confined, 
would be bent, unless the tie were loose enough 
to slip up with the growth. As the blooms 
develope themselves, it is the fashion to put 
the plants in a house, but shading and plenty 
of air must be attended to as usual, and plenty 
of water must be aiven. According to the size
