Can you provide the locations of the Ewells, the Quarters, the Radley oak, and the school? And how many doors down is Mr. Avery from Miss Maudie?
It would really help. I'm having a hard time visualizing the map.
The Ewells. The "disgrace of Maycomb for three generations," the Ewells live behind the dump outside the town's southern city limits.
The Quarters. Just past the Ewells across the railroad tracks reached by a dirt road that leads from the main highway is the Negro settlement known as the Quarters, where most of the town's African American population resides.
The School. The Maycomb County High School was "around the corner past the Radley place"; the elementary school building stood adjacent to the Radley property, while the high school building was behind the elementary school next to the deer pasture.
The Radley Oak. "Two live oaks stood at the edge of the Radley lot" along the main street, and one of them included the secret knot-hole that provided Jem and Scout with the treasures found within.
Mr. Avery. Dick Avery boards "across the street from Mrs. Henry Lafayette Dubose's house." Mrs. Dubose lives "two doors up the street" from the Finches, and Miss Maudie lives across the street and one house up from Atticus (next door to Miss Stephanie). So, Mr. Avery lives next door to Miss Maudie on the opposite side of the street to the Finches.
