This pictures the reaping hook as still used in India.]

Today the years glide by like pleasant pictures. We are fed, busy and

happy. We almost let the dead bury their dead today while the living

drive forward their tasks, achieving as much in a year as the old ages

did in twenty. We have learned to feed ourselves and the food fills our

bodies and brains with energy which must find expression in useful

accomplishment. “Blessed is he who has found his work to do,” we say

nowadays, “but thrice blessed is he who has found a machine to do it for

him.”

Thread your way back through history to the time when the slender lives

of men expanded into full and useful employment, and you will find that,

so far as raising the world’s food is concerned, it all began with the

invention of the reaper in only the last century. It is interesting to

know something of the precarious entry of this machine and something of

the dark background from which it emerged.

The Reaping Hook or Sickle.

From the first pages of history we find that the reaping hook or sickle

is the earliest tool for harvesting grain of which we have record.

Pliny, in describing the practice of reaping wheat says, “One method is

by means of reaping hooks, by which the straws are cut off in the middle

with sickles and the heads detached by a pair of shears.” Primitive

sickles or reaping hooks made of flint or bronze are found among the

remains left by the older nations. Pictures made in 1400 or 1500 B. C.

upon the tombs at Thebes in Egypt, which are still legible, show slaves

reaping with sickles. This crude tool, brought into use by ancient

Egypt, remained almost stationary as to form and method of use until the

middle of the last century.

The scythe, which is a development from the sickle, enables the operator

to use both hands instead of one. The scythe is still a familiar tool on

our farms, but it serves other purposes than that of being the sole

means of harvesting grain.

The Cradle.

Gradually the blade of the scythe was made lighter, the handle was

lengthened, and fingers added to collect the grain and carry it to the

end of the stroke. With the cradle the cut swath could be laid down

neatly for drying preparatory to being bound into bundles. This tool is

distinctly an American development. The colonists, when they settled in

this country, probably brought with them all the European types of

sickles and scythes, and out of them evolved the cradle.

With the cradle in heavy grain an experienced man could cut about two

acres a day, and another man could rake and bind it into sheaves, so

that two men with the cradle could do the work of six or seven men with

sickles.

The American cradle stands at the head of all hand tools devised for the

harvesting of grain. When it was once perfected, it soon spread to all

countries with very little change in form. Although it has been

displaced almost entirely by the modern reaper, yet there are places in

this country and abroad where conditions are such that reaping machines

are impractical and where the cradle still has work to do.

The upper view shows side-hill harvesters drawn by teams of twenty-eight

horses each. The machines cut the grain, and tie it up in bundles, which

are dropped alongside. The machine in the lower view is self-propelling,

cuts and threshes the grain, throwing out the straw, and places the

grain in sacks ready for loading on the wagon.

Early Attempts to Harvest with Machines.

The beginning of practical efforts in the direction of harvesting by

wholly mechanical means may be said to date from the beginning of the

last century, about the year 1800, although very little progress was

made from that time up to the year 1831.

It is true that the Gauls made use of an instrument nearly two thousand

years before, but this contrivance fell into disuse with the decline of

the Gallic fields. Pliny describes this machine which was used early in

the first century and which might be termed a stripping header.

Palladius, four centuries later, describes the same sort of machine.

This device of the Gauls had lance-shaped knives, or teeth with

sharpened sides, projecting from a bar, like guard teeth, but set close

together to form a sort of comb. As it was pushed forward, the stalks

next the heads came between these sharp teeth and were cut or stripped

off into a box attached to and behind the cutter bar and carried by two

wheels. When the box was filled with heads, the machine was driven in

and emptied. This is the way in which it is supposed that it was worked,

and the illustration is the generally accepted representation of it as

roughly reconstructed from the old Latin description of Pliny.

Near the close of the past century, the subject of grain-reaping

machines again began to claim the attention of inventors. In July, 1799,

the first English patent was granted to Joseph Boyce. In 1806, Gladstone

of England built and patented a machine which not only attempted to cut

the grain, but also to deliver it in gavels to be bound. In 1807,

Plucknett and Salmon both patented machines. In 1811, Smith and Kerr

took out patents. In 1822, Henry Ogle, a schoolmaster of Rennington,

assisted by Thomas and Joseph Brown, invented the so-called Ogle reaper.

The next, and last, reaper of this period was invented by Patrick Bell

of Carmyllie, Scotland, in 1826.

Nearly all of these early reapers relied upon scythes or cutters with a

rotary motion or vibrating shears. This method of cutting was

essentially wrong, and none of the machines ever appeared to have gained

or long retained the favor of the farmers. That these early attempts

were all unsuccessful is evidenced by the fact that at the great World’s

Fair in London in 1851, the United Kingdom could not present a single

reaping machine. English journals and writers of that period, without a

single exception, spoke of the American reapers which were exhibited as

“completely successful.” For the real progress towards solving the

problem of harvesting grain with machines we must turn to America.

[Illustration: THE MCCORMICK REAPER OF 1845]

American invention in this line, so far as there is any record, began

with the patent issued to Richard French and T. J. Hawkins of New

Jersey, May 17, 1803. No reliable description of this machine seems to

be extant. Five patents of no importance were issued between that time

and 1822, when Bailey took out a patent. Cope and Cooper of Pennsylvania

obtained a patent in 1826, and Manning obtained one in 1831.

[Illustration: A CORN BINDER CUTS THE HEAVIEST CORN WITH EASE]

Up to 1831, no successful and practical reaper had been developed. With

all the patents taken out in England, and with those taken out in

America from 1803 down to 1831, we might say that nothing had been

accomplished toward perfecting a reaping machine which actually worked

successfully.
