For example, the picture of the landing of the Pilgrims on the shores of Massachusetts will bring to mind the facts which led to their making the journey. It will also suggest circumstances after the landing. Those stories and facts which the child hears, while looking at the picture, are joined with it in the mind by the law of association, and the operation of the same natural law will tend to recall them whenever the child sees the picture. A series of large pictures, which all of the class can see while the history lesson is being studied and recited, would help in fixing the facts in the minds of the children. Children who are taught to visualize can form their own pictures and have a wonderful advantage. Remembering History Dates This troublesome matter is easily mastered when the child understands the use of the number code as given in the book on Memory. This principle can be applied in every case. As a rule, the century in which the date occurs is not confusing, and the effort can be confined to the particular year. For example, in order to remember the date of the Battle of Bunker Hill, it is only necessary to remember '75, for the year, as every student will know that it was in 1775 and not 1875, or 1675. A boy twelve years of age learned more history dates in one week after knowing how to use the Number Code than he had learned in weeks before. The knowledge of how to visualize the lesson and how to remember the dates will overcome any prejudice or any difficulty which the child may have with history lessons. The following are samples of how the Number Code has been applied to remembering history dates: Landing of the English at Jamestown, 1607. During the first year there was much sickness and the word SICK is '07. The picture of the Jamestown settlers "sick on the beach" will fix the year in mind. The following dates were in one lesson, and are the word-pictures which a child used in remembering them. Marquette and Joliet explored the Mississippi River in 1673. The word COMB is '73. They were "combing" the river. LaSalle reached the mouth of the Mississippi River in 1682. He planted the French flag and had a celebration. FUN is '82, they had fun when they planted the flag. New Orleans was settled by Bienville in 1718. He had a hard time finding a good place for the city, TOUGH (tuf) is '18, they had a tough time. Washington and the Virginian troops drove the French troops from Fort DuQuesne in 1754. He drove them from their LAIR, '54. General Braddock was defeated and killed in 1755. He was buried in the woods of Pennsylvania. '55 is LILY, see a lily on his grave. Some other examples follow: Alaska was purchased in 1867. 18 may be DOVE and '67 CHECK, a picture of a DOVE flying to Russia with the CHECK. Or if you prefer you can use the two words, STOVE-SHACK, or TOUGH-JOKE, it was a tough joke on Russia to sell it for so little.
