of P. Thomsonianum, according to the Kew authorities, is

PACKING. Fruits. Peaches and Nectarines must 
not be over-ripe, or they are sure to bruise in transit. 
They should be packed in boxes only deep enough to 
take one layer, and the bottom bedded with wood wool. 
Each fruit should be carefully wrapped in tissue-paper 
and surrounded with fine wood wool to prevént the 
fruits from touching or moving in transit. Any empty 
space must be filled with packing material, and the lid 
of the box serewed, not nailed, down. 
PHONIA. Herbaceous Ponies, both Singles (Fig. 
612) and Doubles (Fig. 613), are of such value to the 
gardener that no one can really afford to have them un- 
represented, They are amongst the hardiest flowers that 
ean be named, brilliant, even gorgeous, of colour, or yet 
again, of the most delicate shades, sweet of scent, and 
attractive as to foliage, the tints of the Peony plants 
in spring and autumn being incomparably beautiful. How 
different the present-day varieties from the old ones 
which did duty in gardens thirty years ago, restricted as 
to colour, and the scent of which was positively repug- 
nant! The best time to plant is early autumn. 
Unfortunately it is not everywhere that these gorgeous 
Ponies will flourish. They need a good, rich, well- 
trenched soil, and it is useless attempting their culture 
in a poor one. Position is of some importance with the 
Peony, and some of the best specimen&’ we have seen 
have been grown between the shelter of fruit trees or in 
the shrubbery borders. A south-west, west, or even a 
north-west aspect suits them best; an east or a south- 
east aspect is not good. The fact is, the Prony forms 
its buds very early in the season, and thongh the 
plants are capable of enduring severe frosts with 
impunity, yet if the buds are frozen, and then the sun’s 
rays fall directly upon them, they are spoilt for a 
certainty. Usually this is not noticeable until long 
after the damage is done. If more consideration were
