state TT for the gourmand's table. When in
very decayed condition these grapes may
sell at cents per pound, but the ordinary
quotation is u cents. Could California
grapes be obtained at II cents per pound
Iney would have the command of
the market everywhere. AS it would
not pay to pack them in sawduSt, owing to
high transportation rates, and the boxes
would arrive In neat and orderly state
California grapes might even sell as well as
Inc conslgnments from the Channel Islands,
Jersey and Guernsey, which usually fetch
not less than 36 cents per pound. The
channel island grapes are grown under
glass, but artificial heat is only required oc-
caslonaily. With q cents per pound the
vineyards might hope to enter upon very
eGneouIaglng era OF prosperity. France and
Oetmany are not large contributors of
grapes TO the English market; they pay
more attention to wine.
VEGETABLE SUPPLIES.
Ii Is question whether something conld
not be done TO supply the English with
vegetables at certain seasons. A California
winter has good deal more sunshine than
an English summer, and we have far more
vegetables IN winter than are needed in
local marts. Would it pay to send green
peas and new potatoes TO England? Only
month or SIX weeks ago sacks OF new pota-
toes were accumUlating on JacksOn-StTeet
wharf far beyond the ability Of the commits
i
front par'ance, they were only con-
sidered fit for the fishes" The Eng
llsh would nay very high fgufes for such
2 supply. The first potatoes OF the year in
London and ether centers come from Jer-
sey and the Settles, the latter lying west of
Cornwall, and the other island uff the Brit
tany coast. The price OF the first arrivals
averages from Is TO . cents per pound, aud
the Jersey growers expect Oh tie spot not
less than y cents per pound for their whole
erop. which they usually begin to gather
by the lSt OF April. Nothing can be said
for the quality. The variety favored
Dy the gardeners and small farmers of
these islands is the kidney and almost
as soon as the tubers are preSentable they
are dug up and sent to market. Only good
treneh cook could redeem them from the
SAD ana WaXY condition they are usually Ia
when boiled. il would require an artist Of
distinction to render them mealy. Peas are
scarce in England well into spring and the
supply al no time is superintendent. A
L0ndoner who could see the California
market vegetable stalls in March would be
aghast at the good things Of life totally be-
yOnd the range Of money IN the British
metropolis and so cheap that the poorest
may buy.
