much more completely and thoroughly
than had ever been done before.
Wiley & Co., firm of analytical
chemists of Baltimore, of undoubted
reputation and ability, whose name
and work are international, were Sc
/ lected after due investigation, as the
firm best equipped to carry on the
analyses of the Exchange.
! Four different sets of experiments
were carried on simultaneously. First,
arrangements were made with grow
ers in seven localities in the state
whereby they would select a certain
tree in their groves, which should not
be picked for any purpose except for
these experiments, through the season
Of 19l1-12. On the same day every
month, at intervals Of a month apart
one dozen oranges were picked from
each Of these trees and sent to Wiley
& Co. for analysis. On arrival, the
juice was carefully extracted from the
oranges, thoroughly mixed and then
tasted. The taste Of the juice was
classified as very souri, sour"
tart" Sweet" or very sweet AT
ter this notation was made on the
test sheet, the analysis was proceed
ed with for total determination in &C
cordance with the outlines of the ex-
periments carried on by Drs. Bigelow
and Gore, of the United States depart
ment of agriculture some years previ-
GUS.
The seven trees so selected were as
follows: A Homosassa in Polk county:
a Parson Brown at Lake Wier; an In
dian River Seeding tree at Minis a
Volusia, county Seeding at Lake Hell
en-; a DeSoto county seeding at Pun
ia Gorda: a whitehy infested sweet
Seeding in Orange county and South
Lake Apopka Valencia late orange
In addition to these eHperim ents,
arrangements were made with the
Winter Park packing house to take
on the same day one orange from
each and every bin in the Bull Dog"
sizers in that packing house, packing
them up and marketing the package;
Bull Dog" at the same time taking
one orange from every bin in the
Camel sizers in the packing house,
marking that sample: Camel"
These samples were sent each week.
during the entire time the house was
in operation, from November to
March, inclusive, and were analysed
for citric acid and total sugar as in
vert by Wiley & Co.
Further in order to get as nearly as
possible a general average of the con-
tents of fruit shipped from Florida to
the Northern markets, arrangements
were made in the Boston, Cincinnati,
Philadelphia and New York auctions
as follows: At each Of these points
sample of Florida oranges was taken
from each and every car sold at the
auction of each and every auction sale
held at these points in the months of
December, January and February.
At the New York auction, samples
of the California navels were taken in
the same way-that is, sample from
each and every car sold at every sale
held in New York for the months of
December, January, February, March,
and the first fifteen days in April.
The greatest care was taken in this
entire line of experiments to remove
as nearly as possible all elements of
error, either in the selection of the
samples or in the chemical determine
tons. In the neighborhood of three
hundred complete analyses were made
in carrying out this plan, and the tab
ulated result is very interesting.
It is especially interesting to note
that all the samples Of orange juice
that were marked Very Sour" aver
AGED AS times as much sugar as cit
rio acid. All the analyses of oranges
which were marked sour showed an
average of 4.S7 times as much sugar
as citric acid. All the analyses of or
anges which were classed as tart"
showed an average of 1928 times as
much sugar as citric acid, while the
average of all the samples designated
sweet was SO times as much sugar
as citric acid, and the very sweet"
averaged 1908 times as
much sugar as citric acid In every
case the sugar as calculated is total
sugar as invert and the percentages
Ire percentages in weight to the total
weight of the juice.
AS before stated, in every case, no
natter from. what source the sample
vas received by Wiley & Co. on ar
'tval, the juice from each separate
sample was carefully extracted, and
before being analysed, was thoroughly
mixed to make true, composite sam
Die of juice from the whole, and then
asted for sweetness. The taste Of
he juice in every experiment-some
hree hundred in number was CLASH
led either as very sour" sour"
tart" sweet or very sweet" and
t was not until after this determine
ion of flavor had been made and not
ID on the data sheet of the test that
he analysis was proceeded with.
With this explanation, the table Of
results as calculated, is given below:
