A Letter to the Editor, 
'he Spread of the American Goose¬ 
berry Mildew in England. 
Sir,—In view of an important stage 
iving been reached in relation to the 
love matter, will you kindly allow me 
>ace for the following remarks. 
Royal Assent was given last Thursday 
■ . “ The -Destructive Insects and Pests 
ct, 1907,” and the Board of Agriculture 
ill now be able, under this new law, to 
sue an order against American Goose- 
wry mildew. 
1 wish to point out how matters stand 
this juncture, and especially to em- 
tasise the necessity for growers to co- 
>erate with the Board to stamp out this 
■tv pest. 
During the past few weeks I have visited 
fected Gooseberry plantations in Wor- 
stershire, Gloucestershire, and Norfolk, 
id in many cases I have seen the berries, 
aves, and young shoots smothered with 
e white powdery masses of spores of 
e American Gooseberry Mildew. Ex- 
rience in this country has already 
own, (as it has in other countries 
' the Continent), that severe prun- 
T i n the winter and frequent spray- 
i 1 ? during the spring and summer 
onths do not eradicate the disease, and 
at the only certain way of dealing with 
is pest, if we wish to stamp it out before 
spreads through the country, is to grub 
' and burn the affected bushes. 
Already instances have occurred of con- 
lerable losses to growers caused by this 
w disease. In one case a grower dis- 
vered the disease in his nursery, and it 
is not until he had grubbed up and 
rnt the whole -of his nursery stock, of 
2 value of some £70, that the danger 
the disease spreading to the adjacent 
>oseberry plantations (of a large acre¬ 
s' was removed. In another case the 
;s was more serious still. Here in a 
antation of some 14 acres not only had 
: the Gooseberry bushes to be" des¬ 
ired, but, as I found the mildew had 
read to Red Currant bushes growing 
ermixed with the Gooseberries it was 
cessarv to grub up and burn these also 
order to ensure the eradication of the 
disease and safeguard the surrounding un¬ 
affected plantations. The total loss in this 
case amounted to some hundreds of 
pounds. In a third case a nurseryman 
lost a considerable sum of money through 
the necessity of having to burn a large 
stock of recently imported standard 
Gooseberries affected with the disease. 
It is clear that growers are just begin¬ 
ning to experience the spread of a disease 
which, unless resolutely stamped out, will 
gradually invade and ruin their Goose¬ 
berry plantations, just as the “ Big Bud ” 
mite has ruined Black Currant planta¬ 
tions. 
The disease has been allowed seven 
years’ start in Ireland, and two or three 
years’ start in England. Now that the 
Board has at length acquired the neces¬ 
sary legislative powers to deal with the 
disease, it behoves all growers and gar¬ 
deners generally to co-operate heartily 
with the Board if they wish to see the 
American Gooseberry Mildew stamped 
out and their Gooseberry plantations kept 
healthy. 
Up to the present the outbreaks that 
have occurred in England are as follows : 
Kent, on standard Gooseberries, only in 
one nursery (disease believed to be now 
stamped out); Worcestershire, 31 out¬ 
breaks in Gooseberry plantations ; Glou¬ 
cestershire, one outbreak; Wisbech and 
district, two outbreaks; Warwickshire, 
one outbreak.

HOW TO GROW 
= = Celery. 
To grow good Celery a light rich soil 
is required. For an early crop a sowing 
should be made in heat in the beginning 
of February. When the seeds begin to 
germinate a lower temperature will suit 
them better. As soon as they are fit to 
handle prick the seedlings off into boxes 
in a compost of well-rotted dung and leaf 
mould. The boxes should be placed as 
near the glass as possible in a house 
where there is a gentle heat of, say, 50 
deg. to 55 deg. The first week in March 
is a good time for sowing for a main 
crop. A gentle heat such as a late vinery 
will suit them. As soon as they are fit to 
handle the seedlings should be pricked 
off into frames in a compost of well-rotted 
dung, leaf mould and loam, well mixed 
and laid on about four inches deep on 
slightly heating materials. A good 
watering should then be given, and the 
sashes put on. As soon as the leaves 
touch one another they should again be 
planted in frames in the same sort of 
compost as before, about four inches 
apart either way. At this planting the 
tap root should be slightly shortened. 
As the weather gets warmer plenty of 
air should be given, pulling the sashes 
completely off in fine weather. Trenches 
should be got ready some time in advance 
of planting out. Very useful trenches 
are two feet wide and four feet between 
the trenches, running, if possible, in a 
north and south direction. 
If the soil is of poor quality a good 
laver of well-rotted cow and horse dung 
mixed in the bottom of the trenches will 
be beneficial. Three or four inches of the 
top soil should then be put on the top of 
this. The plants will" require a good 
watering preparatory to lifting them from 
the frames. They should be carefully 
lifted with good balls, and any side shoots 
should be removed before planting into 
the trenches in double rows, nine inches 
apart either way. After planting, the 
plants should never be let suffer for want 
of water, and after they have made a fair 
good growth the first earthing up should 
be done. Before earthing up, the plants 
should be lightly tied with matting to 
keep them in position. Care will have 
to be exercised to keep the soil from get¬ 
ting into the hearts of the plants, and the 
soil should not be pressed too firmly 
against the plants, especially if it be of a 
heavy nature. 
Earthing up should be continued at in¬ 
tervals of about 10 days, in dry weather if 
possible, as it is much better to earth up 
little and often than wait until it has 
almost grown to its full height and then 
earthing up all at once. Kaffir.
