should receive copious supplies of weak liquid manure, 
with an occasional application of nitrate of soda (loz. in 
4galls. of water is sufficient).

growth most exhibitors wrap the plants in double or treble 
folds of stout brown paper. 
Sorts. White varieties are usually deficient in flavour, 
and are only useful when the vegetable is required early 
, orfor soups. The best flavoured are Sutton’s 
White Gem, Sandringham White, and Incom- 
parable Dwarf White. The pink or red 
varieties are crisp in flavour, and also keep 
longer and sounder than the white sorts. 
Some of the best sorts are Leicester Red, 
Major Clarke Red, Williams’s Matchless Red, 
Wright’s Grove Red and Wright’s Grove 
Pink, Standard-Bearer, Nonsuch Pink, and 
Sulham Prize Pink. These are all hardy 
varieties of gocd quality. None of the 
so-called self-blanching varieties are what 
their name indicates, and few, if any, gar- 
deners consider them worth growing. 
CELERY FLY (Tephritis onopordinis). 
Popularly this is associated with the Celery 
only, but it is equally as destructive to Par- 
snips (on whose foliage the large blisters caused 
by the leaf-mining pests are very familiar). 
The fly (Fig. 224) is tin. in wing expanse, and 
yellowish brown, with rusty-coloured spots. 
The female deposits the eggs upon the foliage, 
and from these hatch out thick-bodied, leg- 
less, green maggots, slightly pointed at the 
head, and when full-grown about jin. long. 
There are two or three broods in a season. 
As stated in Vol. I., the best way of 
dealing with the pest in the case of small 
gardens is by crushing the grub between finger 
and thumb; but where large areas are under 
cultivation thisis impossible. Spraying with 
weak kerosene emulsion should then be. 
adopted. In either case all leaves should be 
destroyed by burning when the crop is lifted, 
and not put on the manure-heap. Quicklime 
should also be incorporated with the soil. 
CELERY STEM FLY. This insect, 
described in Vol. III. under its scientific name 
of Piophila apii, proves very troublesome in 
some seasons, the maggots tunnelling the 
stems and causing them to rot. There is 
more than one generation, and though in the 
earliest the pupal state is passed in the soil, 
as suggested in the volume above referred 
to, in the later ones it is assumed in the soil. 
Feeding as it does in the stems, the pest 
cannot well be reached. Spraying with kero- 
sene emulsion as a preventive measure is, 
however desirable, and especially in gardens 
where the insect was known to exist the 
previous season. All diseased portions of 
plants should be carefully burnt, and after
