Survey the cutting-edge engineering methods from the early 20th century and see how ships, magazines, and fortifications were studied and improved.
This book presents actual reports from the United States Army Corps of Engineers around 1906, illustrating practical approaches to surveying waterways, testing devices, and strengthening harbor structures. It includes detailed descriptions of instruments like the bathometer and real-cost breakdowns for lining powder magazines with copper and cedar.
The volume blends field notes with engineering drawings and administrative correspondence, showing how new techniques were documented, evaluated, and applied in defense works and river and harbor projects. You’ll get a window into how engineers measured depth, tracked channel changes, and planned fireproof, durable buildings using concrete and cedar.
- Explanations of the bathometer, its components, and how it recorded water depth on a paper disk.
- Case studies of concrete features and weatherproofing at fortifications and storehouses.
- Itemized cost tables and project progress notes from lining powder magazines with copper and cedar.
- Historical context on how these methods supported navigation, safety, and defense infrastructure.
Ideal for readers of engineering history, naval logistics, and early 20th‑century public works, this edition offers concrete examples of measurement, construction, and project accounting in action.
