state fit for the gourmand's table When in
a very deeayed condition these grapes may
sell at cents per pound, but the ordinary
quotation is y cents. Could California
grapes be obtained at II cents per pound
they 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 rs
the eonsignments from the Channel Islands,
Jersey and Guernsey, which usually fetch
not less THAN 20 cents per pound. The
Channel Island grapes are grown under
glass, but artificial heat is only REQUIRED oc-
casionaily. With q cents per pound the
vineyards might hope to enter upon very
encouraging era OF prosperity. France and
Germany are not large contributors of
grapes to the English market; they pay
more attention to wine.
VEGETABLE SUPPLIES.
II IS question whether something. could
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-Street
wharf lar beyond the ability Of the commits
sion agents to dispose Of them. In water
front pafiance, they were only con-
sideTed fit for the fishes" The Eng
fish would pay very high fgufes for such
2 supply. The first potatoes OF tile year in
LoDd0n and ether centers come from Jer-
sey and the Settles the latter lying west of
Cornwall, and the other island off the Brit
tany coast. The price OF the first arrivals
averages from Is TO . cents per pound, aud
the Jersey growers expect on tile SPOT not
pgn for tafF Ia
crop. which they usually begin TO gather
by the LIST of April. Nothing can be said
for the quality. The variety favored
by the gardeners and small farmers of
these Islands is the kidney, and almost
as soon as the tuberS are presentable they
are dug ND and sent to market Only good
French cook could redeem them from the
sad and waXY condition they are usually in
when boiled. Ii would require an artist of
distinction 10 render them mealy, Peas are
scarce in England well into spring and the
supply al no time is superabundant. A
Londoner 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 ia the British
metropolis and SO cheap that the poorest
may buy.
REFRIGEBATING APPARATUS.

ing in England from New Zealand. The
