This machine binds the grain with wire.]

The self-binding harvester was borne on the shoulders of the Marsh

harvester. Carpenter, Locke, Gordon, Appleby and every inventor who

succeeded in any measure in binding grain, first did so by placing his

binding attachment upon a Marsh harvester, taking the grain from a

receptacle where it fell to another receptacle where it was bound. The

first record of these attempts is a patent granted to J. E. Heath, of

Warren, Ohio, in 1850. Watson, Renwick and Watson secured patents in

1851 and 1853, but their machines were very complicated and never more

than experiments. From that time until 1865 many patents were granted,

none of which may be considered successful.

In 1865 S. D. Locke of Janesville secured a patent which ultimately

developed into the Withington wire binder first put out by McCormick in

1875.

The Withington machine was an improvement on the binding device patented

by Locke in 1865. McCormick built 50,000 of these machines between 1877

and 1885. It was a simple mechanism which consisted mainly of two steel

fingers that moved back and forth and twisted a wire band around each

sheaf of grain.

Farmers did not take kindly to the wire binder. They said that wire

would mix with the straw and kill their horses and cattle.

The Twine Binder.

This is the perfected Marsh harvester with a perfected Appleby twine

binding attachment and was first put out by the Deering Company in

1879.]

These machines cut a swath 40 feet wide in the grain field, gathering

the grain into bundles and dropping them alongside to be picked up by

the sweep rake.]

This was the situation in the harvesting industry about the time that

William Deering took an active interest. He looked about for a better

machine. He found John F. Appleby, who, in 1878, had perfected a twine

binder attachment. When Deering saw the strong steel arms flash a cord

around a bundle of grain, tie a knot, cut the cord and fling off the

sheaf, he knew he had what the world needed. Appleby began working on

his invention in 1858, but accomplished nothing until 1869 when he took

out his first patent on a “wire binder.” In 1874 he began what is known

as the Appleby twine binder, operating one in 1875 and 1876 and several

in 1877. In 1879 Deering bought out Gammon, joined forces with Appleby,

moved the factory from Plano to Chicago in 1880, and began putting out

twine binders. In 1881 McCormick, also, and Champion began building the

Appleby binder.

With the development of an attachment to bind with twine, a new problem

arose--where to get a cheap serviceable twine. William Deering again

arose to the occasion. He met Edwin H. Fitler in Philadelphia, one of

the three twine makers in the United States, and after a good deal of

persuasion induced him to take an order for a single-strand binder

twine. From that time on, all manufacturers have been building

practically the same machine--the Appleby binding attachment on the

Marsh type of harvester which, in turn, was founded on the McCormick

cutting mechanism. The self-binder of today is of that type.

Other Machines Follow.

The completion of the reaper set the wheels of farm invention spinning.

It was the first great battle successfully won and gave a spirit of

confidence and an irresistible spirit of victory to the men who were

lifting the burdens off the bodies of men. After the reaper, the mowing

machine came naturally. Following the binder in easy sequences came the

corn binder, push binder, header and harvester thresher.

Every variety of haying machine, from side-delivery rake and tedder to

sweep rake and loader, came eventually to make hay-making easy. The

thresher, ensilage cutter, riding plow, disk harrow, cream separator,

manure spreader and seeding machines succeeded in making the raising of

the world’s food a profitable occupation; at the same time, they made it

an easy one. Lately, the internal combustion engine, together with its

application in the kerosene tractor, promises to make the farmer’s

emancipation practically complete. If Herbert Casson could say “The

United States owes more to the reaper than it does to the factory or the

railroad or the Wall Street stock exchange,” what can be said of these

myriad machines that now do the food-grower’s work for him?

Where formerly nearly all the people had to engage in food raising and

even then went to bed hungry, now nearly half the people live away from

the farm and there is a great abundance of bread and of food.

What Causes an Echo?

An echo is caused by the reflection of sound waves at some moderately

even surface, such as the wall of a building. The waves of sound on

meeting the surface are turned back in their course, according to the

same laws that hold for reflection of light. In order that the echo may

return to the place from which the sound proceeds, the reflection must

be direct, and not at an angle to the line of transmission, otherwise

the echo may be heard by others, but not by the transmitter of the

sound. This may be effected either by a reflecting surface at right

angles to the line of transmission or by several reflecting surfaces,

which end in bringing the sound back to the point of issue.

Sound travels about 1,125 feet in a second; consequently, an observer

standing at half that distance from the reflecting object would hear the

echo a second later than the sound. Such an echo would repeat as many

words and syllables as could be heard in a second. As the distance

decreases the echo repeats fewer syllables till it becomes monosyllabic.

The most practiced ear cannot distinguish in a second more than from

nine to twelve successive sounds, so that a distance of not less than

sixty feet is needed to enable a common ear to distinguish between the

echo and the original sounds. At a near distance the echo only clouds

the original sounds. This often interferes with the hearing in churches

and other large buildings. Woods, rocks and mountains produce natural

echoes in every variety, for which particular localities have become

famous.

In Greek mythology, Echo was a nymph (one of the Oreads) who fell in

love with Narcissus, and because he did not reciprocate her affection

she pined away until nothing was left but her voice.
