- View a picture of a sickle.
- View a picture of sheaves of wheat.
- Read (and view) how a grain cradle was used in “Bittersweet.”
- Note how much grain could be harvested by one person with the sickle and the amount of yield. (One day — 1/2 acre of wheat — 5–20 bushels yield.) Compare that to the amount of grain that could be harvested with the grain cradle. (One day — 2–2 1/2 acres of wheat — 2–3 times the harvest over the sickle).

- At the time the book was written, four billion bushels of wheat were produced in the world each year. According to a commodity conversion table, one bushel of wheat is approximately 60 lbs. How much wheat in metric tons was produced in the world at the time the book was written? 1 Metric Ton = 2204.62 Pounds (108,862,298 million tons) Compare that amount to the amount that is produced today.

- More about Cyrus McCormick and the reaper from the Book of Knowledge:
In the early days of North America, grain was cut with a sickle. You may have seen a picture of one somewhere; it is shaped like a question mark. A man gathered grain by holding it in one hand and cutting it free with the sickle in the other. Next, a “cradle” was used. This was a long curved knife at the end of a handle; it had wooden fingers which kept the grain from falling….
The first attempts to make a grain-cutting machine were made in Great Britain. Henry Ogle, a schoolmaster of Rennington, made a mechanical reaper in 1822, and Patrick Bell, a young Scottish student, invented a more advanced type four years later.
Obed Hussey and Cyrus Hall McCormick, two Americans, worked at the same time on a new machine to cut grain. Both received patents, one in 1833 and the other in 1834. McCormick’s was the more successful. This machine, which was drawn by horses, cut more than could be cut by the hands of many men. At once others began attempts to improve the McCormick invention; and just before the American Civil War, John E. Heath invented a machine which not only cut the grain, but tied it into bundles, thus saving much more time.
In 1875 John F. Appleby, who had invented a successful twine-knotter some years before, made a binder which has proved to be the basis for modern machines of this type. In later years a threshing machine was added to the reaping operation, thereby separating the grain from the chaff as the farmer moves along the fields.
