a plant of this sort, treated as above, in full flower last July, formed a 
complete cone two feet and a half high, with at least 500 blossoms 
of the full size at one time; but I find this, together with C. Whee¬ 
led, atrosanguinea, Hopeana, Youngii-pallida, Epsomiensis, mon- 
strosa, pulchella, white and crimson, ochre and crimson, and cream 
and crimson delights in a compost something different from that re¬ 
commended for C. Youngii, &e. Instead of any vegetable mould, add 
to the dung and sand one-fourth part turfy loam, as free as possible 
front oxide of iron. I possess many other fine hybrids, but not hav¬ 
ing tried them in different soils, I am not so well able to speak about 
them at present. To have any fine sorts in flower late in the au¬ 
tumn, nothing more is necessary than, as soon as the terminal flow¬ 
ers of the principal racemes are got to the full size (I am supposing 
the plants to be blooming in pots during summer,) to cut the entire 
branches down to within an inch of the surface. Then take off about 
an inch of soil, and replace with fresh compost sifted; this will in 
general happen about the end of July. When this is done, place the 
plants in a cold frame where they can be sheltered from rains by a 
Covering, and in about a month, they will be fine vigorous plants, 
producing plenty of flower stems, which will flower in the green¬ 
house during October and November. The sorts best calculated for 
the second blooming are— 
Calceolaria, Cream and Crimson* 
- Ochre and Crimson* 
Calceolaria Youngii. 
polyantha. 
Youngii pallida, 
picta. 
pi eta pallida. 
White and Crimson. 
Wheeleri* 
farinosa. 
monstrosa. 
Atkinsonii. 
atrosanguinea. 
I'f, contrary to my expectations, you make use of this paper, I 
may shortly trouble you again.

The art of judicious thinning and pruning, as practised by a few 
modern planters, is calculated to accelerate, in an extraordinary de¬
