Ae box for an instrument, a Keuffel & Esser level.

Part of a collection of Professor William H. Day's work equipment, donated by Joe Saint. Both the case and level were originally owned by Professor William H. Day, who was integral to the Holland Marsh Drainage Scheme's beginnings. The equipment was traded to Len Saint in the 1930s for a truck. The survey of the marsh determined the elevation of the muck soil and the bordering "highland" soils, providing the information the planners would need to determine the grades, estimate the materials to be moved and to determine the alignment of the canal.
