Jason Edwards: An Average Man: Jason Edwards: an Average Man is an 1892 novel by American author Hamlin Garland.  First published by the Arena Publishing Company in Boston, the novel is divided into two parts entitled "The Mechanic" and "The Farmer", respectively.  There are two major settings that accompany each section.  In the first part, the setting is in Boston and then moves to Boomtown, a prairie town in the Midwest, in the second part.  The book takes place over a period of ten years, beginning in 1879 and finishing in 1889, but an important part of the novel takes place in 1884 as well.  Most scenes written about in the novel are set in the summer months.  "Jason Edwards" takes place during the Gilded Age in American History.

Book of Leviticus: The Book of Leviticus ( ) is the third book of the Jewish Bible and the third book of the Old Testament.  The book addresses all the people of Israel (1:2) though some passages specifically address the priests (6:8).  Most of its chapters (1–7, 11–27) consist of God's speeches to Moses which he is commanded to repeat to the Israelites.  This takes place within the story of the Israelites' Exodus after they escaped Egypt and reached Mt. Sinai (Exodus 19:1).  The Book of Exodus narrates how Moses led the Israelites in building the Tabernacle (Exodus 35–40) based on God's instructions (Exodus 25–31).  Then in Leviticus, God tells the Israelites and their priests how to make offerings in the Tabernacle and how to conduct themselves while camped around the holy tent sanctuary.  Leviticus takes place during the month or month-and-a-half between the completion of the Tabernacle (Exodus 40:17) and the Israelites' departure from Sinai (Numbers 1:1, 10:11).

Making an American Citizen: Ivan Orloff (Lee Beggs) and his unnamed wife (Blanche Cornwall) are poor peasants, presumably living in the Russian Empire.  Ivan is shown sitting on a cart while his wife walks alongside their horse, helping to pull the cart.  The husband whips both the horse and his wife indiscriminately.  The wife is represented as completely subordinated, as just another beast.  On their way, they meet a group of emigrants who invite Ivan to join them.  When Ivan, together with his wife, arrives in America, "the land of freedom," he learns four "lesson[s] in Americanism" that turn him into a respectful husband with regard to his wife.  The first lesson takes place upon landing.  Ivan has his wife carry a huge bundle on her back.  When she succumbs under the weight of the bundle, Ivan starts prodding her with a stick, threatening to beat her.  A gentleman approaches them, picks up the bundle and puts it on Ivan's back.  The gentleman takes the stick from Ivan, hands it to the wife and shows her how to prod Ivan.  The second "lesson in Americanism" takes place in the couple's new home at Odessa Inn.  Threatening his wife, Ivan asks her to take off his shoes.  He beats her and knocks her to the floor.  A man comes in and asks Ivan to put the wife in bed.  After Ivan reluctantly does that, the man knocks him down to the floor the way Ivan did to his wife.  The third lesson takes place in the countryside.  The couple no longer lives at the inn but owns a house and some land.  The wife no longer wears a scarf.  She toils in the garden, while Ivan sits in a chair smoking a pipe.  When she protests, Ivan goes to beat her, but a passer-by stops him and punches him several times, forcing him to tend to his wife who has fainted and work instead of her.  Ivan's wife begins to live in an increasingly "American way."  She learns to stand up to his abuse.  They have another feud, this time while having dinner in their house.  While they are scuffling with each other, two men come in and break them up.  For Ivan's fourth and final "lesson in Americanism," he gets sentenced to hard labor for six months.  In prison, he cracks and becomes "completely Americanized."  The ending shows Ivan in the garden and his wife calling him for dinner.  As they sit down to the table, they both seem happy and equal.
