MISCALCULATION

What is said to be the largest plow in the world was made

some years ago at Bakersfield, Cal. This plow was the result

of the ingenuity of a ranch superintendent, who had authority

to make improvements, but not to introduce steam-plows. The

superintendent had grown very tired of preparing three thousand

acres of land for wheat with ordinary nine- or twelve-inch plows

drawn by two horses.

He argued that if two horses could pull a twelve-inch plow,

six horses could pull a plow thirty-six inches wide, and that

eight horses could pull a plow forty-eight inches wide. He made

the calculations carefully, and, being clever with his pencil,

made drawings also, and sent for blacksmiths and machinists to

construct a plow on his principle.

Some simple folk told him that his great plow would not work,

but they contented themselves with saying this dogmatically,

without giving any mathematical reason therefore. So the

superintendent went on with his plans.

The blacksmiths and machinists finished the plow in due time.

The share was made to cut a fifty-inch furrow; the top of it

reached five feet above the ground, to give room to throw the

earth. The beam was more than a foot thick; but the machine was

constructed to run between two great wheels, so that it could be

turned around easily; and on the axle between these wheels was

the seat for the man who was to drive the ten horses which were

hitched to it.

The plow was brought to the great field, the ten horses were

attached to it, the handles were raised, the driver mounted his

seat, and the team was started. But as soon as the share struck

well into the ground the horses stopt short. They were stuck

fast. And yet the plow had not gone too deeply into the earth.

But it was evident that they could not pull the plow. More

horses were brought out, but not until fifty were attached did

the plow move along.

Even then it required four men to hold the handles, in order to

keep the plow in the furrow. It was an economic failure.

Then the superintendent, through the intervention of some one

who was a better mathematician than he, learned that he should

have cubed the capacity of his twelve-inch plow every time he

doubled the width of it.--_Harper’s Weekly._
