The book "History of Davenport and Scott County" mentions School No. 9 in one paragraph in volume I, pages 928-929. It describes the school as Tyler School, No. 9, with no mention of a name change. The text reads as follows:
"School No. 9, the Tyler school, is a handsome building located on the east side of Grand avenue between Locust and High streets, occupying a lot of exceptional size, purchased at a cost of $3,000. The building was erected in 1892 to relieve schools Nos. 1, 2, and 4. It was a well arranged eight room building and so remained until 1902, when it was enlarged by an addition of four rooms on the north side. The exterior attractiveness of the building was not lessened by the addition. The same is true of No. 6 and its addition made in the same year."
Note that the description gives "Tyler school, is a handsome building located on the east side of Grand avenue between Locust and High streets, occupying a lot of exceptional size."
Here is a map of the area.
You see Locust and High Streets, Grand Avenue and Bixs home (red A).
Clearly, there were no houses across the street from Bixs house.
