purpose tractors that can be used eco
nomically on farms of under 100 till
able acres.
Prior to 1905 practically all power
blowing was done by steam. II there
was any machine In use at that time
employing an internal-combustion en-
CINE as its source Of power, the case
apparently has never become a matter
Of record. Steam blowing has been
In vogue for number Of years, espe-
cially in regions such as the Dakotas,
Montana, and the Canadian provinces
Of the Northwest. Here were found
bonanza farms consisting Of thousands
Of acres. one crop Of wheat sometimes
paying for the entire farm. These
large tracts, stretching away for miles
In a level and unbroken plain. offered
conditions which were suitable for
these mammoth steam outfits weighing
many tons.
Several factors had a bearing on the
elimination of steam as a source of
power for blowing and the substitu-
ton Of the internal.cOmbustiOn en-
CINE.
The fuel was bulky for the power
transmitted. and the storage space on
the engine was small. Several men
were required. The steam engine as
then constructed could not stand the
constant strain and rough usage neces-
sary In blowing. 1t was necessary to
spend considerable time in care and re-
pair. just as is required by the rail-
road locomotive after a 1--WE or six
hour run.
How Uss Of Gas Engine Began.
There was q demand by operators
for a machine which would do away
with these disadvantages. Interest
was shown by various manufacturers
and their attention was directed to-
ward the development Of a machine
using the internal combustion engine.
Apparently 1905 was the first year
that a gas tractor advertised as
source Of power was placed on
the market. This machine employed
dOuble-cyllnder engine. using gnsO-
line for power and oil for cooling. It
had a rating Of % nominal and 40
actual brake horsepower and was
capable Of pulling six to eight 12-inch
plows, depending on the soil. The
weight was practically the same as
that Of the steam engine. about nine
and one-half tons. While operators
were not satisfied with the steam tract
ors on the market. there was then
considerable prejudice against the gas
tractor. no that machines were built
which looked as much like a steam
engine as possible. Perhaps this fact,
to some extent, tended to overcome the
prejudice and make for the popularity
Of the OUTFIT.
BY 1908 m much interest was mani
fest throughout the Northwest In the
gas tractor that II was decided to hold
motor competition In connection with
the Industrial exhibition at Winnipeg,
Canada. During the week Of July 13-
II, 1908. this contest was held, the
first Of its kind on the American con.
tinent. Machines were exhibited by
I've companies; two other companies
entered. but withdrew. The rules Of
the contest limited the weight to seven
and one.half tons to keep out steam
rigs. This rule barred one gas
tractor. ~ II weighed nine and one
half tons.
Early Tests Unsatisfactory.
The tests upon which final award
was based consisted Of hauling. plow.

soil conditions were not ideal. and

were shown and that II started the

small farms.
