"Johnson's Tables" is a comprehensive collection of mathematical and engineering tables compiled by John Butler Johnson, a prominent figure in the field of civil engineering. Originally published in 1892, this resource provides essential data for surveyors, engineers, and students involved in earthwork calculations and mapping.

The book features stadia and earthwork tables, crucial tools for determining distances and volumes in surveying projects. It also includes four-place logarithms, a logarithmic traverse table, and natural trigonometric functions, offering a wide array of mathematical aids. The inclusion of information on map projections further enhances its utility for cartographers and geographers.

This historical text offers insights into the calculation methods used by engineers and surveyors in the late 19th century and remains a valuable resource for those interested in the history of engineering and mathematics. It demonstrates the meticulous calculations required before the advent of modern computing technologies.
