II Will suffice TO say that 1t was SHOWN 10 ne corecs
and a valuable assistant.
Net only were the exhibitors obliged to go through
the fiery ordeal Of these tests but the grain cut, and
the uneven surface Of the fields, all conspred to rem
der the trial most searching one. 1t was remarked
TO me by one competitor who had been at scores of
trials in this country and had even worked an Amer-
can machine the imperial ri in France, that this
the most rigid tes' ne had ever oeen pun 10, ana
moreover he had never competed with so many ma
chimes AT once The report OF the Judges Will be pre-
sened at the United STATES Fair at Louisville, Sept l.
and from their intelligence aud the close examination
made by them at Syracuse, 1t VIII undoubtedly prove
a most valuable acquisition to our manufacturing
public. One thing is certain: the influence OF this
Trial will be felt at all subsequent ones, and you
may Iely upon it, any uniformed capers to the contra
ypotw Outstanding that the trial has been in the accom-
psbnent of the object sought most decided success
II will have the effect Of showing the farmers OF the
United States that although they may nourish predl,
lections for certain machines because they do good
work in cutting vet the only test OF their excellence
is TO be found IN putting them under rigid eIamna-
tion based upon scientific principles, and every sensible
editor end farmer in the country can do nothing else
than feel respect for the initiative taken by Judge
Gould and his associates.
One test applied to the machines was 10 make the
te am walk rs slowly they could that they put
one foot ahead of the Others ard causing the cutter
bar TO go click click tick, click, like the pendulum OF
X,
the grass was cut at this slow notion The team would
be gradually stopped, and then started again without
backing the machine. Some of the competing mowers
utterly failed this test, thus proving that high rate
of speed required for them to perform their work.
ard the team would consequently be sooner tired out
OF the new machines the list there is one, self
raker Of very excellent principle and simple construc-
tion invented by the veteran Pells Nanny OF Free
port Ill. lie is the father of j. III. Nanny, and origi
hal invt rtor of the widelyknown Mannys machine.
Tie old gentleman has succeeded, he thinks, in
obtaining reaper and mower much superior to his
sons, and, old he, fesressy enters the lists The
patriarch Of all reapels, Obed Hussey Of Baltimore,
here with a novel reaper, which cuts swdth ten
feet wide. There is raker needed with this machine
for the grain ii cut fall upon fitting platform
When enough for gayel aGcumulates upon the plat
form hama riding behind the driver pulls bong
bent lever and the Platform Is caused to tilt up and
drop lis load behind it, while the machine goes its
way. l am surprised that so experienced man as
Obed Hussey should come TO exhibit machine so mani
festly imperfect as this mammoth reaper, and cannot
wonder at biz quitting the field after going around
bis lot. Beside these, there the /" Illinois Har-
vesier' invented by Jonathan IIaines of Pekn, III.
This harvester cuts off only about ls to "A inches
Of stalk with the grain head, and by means
of a a.erally travelling endless apron and elevator,
the grain Is loaded Immediately into wagon driven
alongside With five hands and three teams, beside
the two employed to push forward the machine,
thirty acres OF wheat be well cut and stacked per
day. The President III some OF the Judges and re-
poters went down yesterday TO see Il put to work,
AID the opinion was unanimous that was entitled to
much prase for its excellent performance. 1t is not
tit to cut oats barley or grass but simply wheat,
and therefore will be principally valuable to large
wheat-groweI3 at the West.

previous letter. not completed up TO yesterday
afternoon but will, l understand, be tried by
Special Committee some day this week.
Ny dear TaIBusE, we in New York have no con.
cepton of the extent TO which these wonderful reapes
and mowers are made and sold. Why, Sir what
must be your surprise when tell you tat one single
shop in Illinois hs. turned out this;year far, -four
hOusand siz hundred and ff1y-one combined respers
and mowers which at sl45 each, the retail price for
