THE FLORIST. 
providing blooming accommodation for the latter, when grown 
too large for the cold frames. Under an erection of this kind, 
placed in a sheltered east and west aspect, they will make a 
lengthened and brilliant display. Care must be taken to 
fumigate them thoroughly before they are arranged in it, to 
ensure the death of every green-fly, and also to impregnate 
the plants with the disagreeable flavour of tobacco, that visitors 
of this description may be deterred from remaining. Who 
would select for his morning meal a room filled with the 
odour of stale tobacco-smoke ? The aphide in question has 
as keen a perception of what is disagreeable. 
CULTIVATION OF THE CALCEOLARIA, 
BY MR. W. H. HOLMES, F.H.S. LANDSCAPE-GARDENER, &C. 
I beg to hand you a brief outline of my mode of cultivation of this 
beautiful plant. Although not essentially different from your Whitby 
correspondent, it may be acceptable as an accompaniment to your 
Illustration. 
COMPOST. 
Equal quantities of rotten turf, leaf-mould, good sandy peat, rotten 
cow-dung, and silver sand. 
I send out my plants well established in 4-inch pots in the 
month of 
MARCH. 
Re-pot them into a 6-inch size, giving plenty of drainage, and 
placing a little moss on the top of the sherds. Give a gentle water¬ 
ing with a fine rose. Keep the plants closely shut up in a green¬ 
house or pit for a week. Syringe them every other night; and after 
that, give them plenty of air by day ; but avoid placing them in a 
current of cold air. Screen them from the rays of the mid-day sun 
by a light shade; but nothing can be more beneficial than the morn¬ 
ing sun-light. 
IN APRIL 
Re-pot them ; the strongest plants into a 10-inch, the weaker into a 
smaller size. Calceolarias like a large pot to bloom in. Be parti¬ 
cular at all times to water them with judgment, keeping them neither 
too wet nor too dry; either extreme is injurious, and very frequently 
causes the death of the plants. 
' -MAY. 
If plants are required to form large specimens for exhibition, 
they should now be shifted into 12-inch pots, in which they are to 
bloom. But whenever this shift is given, let a double quantity of
