Arrangement

The card index is arranged roughly chronologically by year, then alphabetically by correspondent. Some cards are grouped by subject or type of record indexed.

Extensive interfiling has occurred, especially in the earlier years of this series. Multiple years are grouped together in the same box and alphabetical filing is not consistent throughout. Certain years are represented by multiple alphabetical sets. For example, Box 1 contains letters A-C from 1901 while Box 2 contains letters A-J for the same year. The arrangement is more consistent as the series progresses and many of the later boxes do not have the issues that earlier boxes do.

In addition to the alphabetical arrangement, many of the boxes contain cards grouped by subject (aqueducts, bridges, dams); type of record (canal contracts, surveys); or major correspondent (state officers, Special Deputy State Engineer).
