The very title of this 1916 volume is a small revolution. That a book had to argue for "the value of science in the smithy and forge" tells you exactly what the smiths of the era thought about scientists — and what the scientists thought about the smiths. The book was co-edited by John Edward Stead, a metallurgist so influential that a chemical etchant still bears his name (Stead's reagent, used to reveal phosphorus banding in steel).

The front matter reads like a recruiting pamphlet for a new priesthood, listing companion volumes a working smith was expected to own. Among them:

The MICROSCOPIC ANALYSIS of METALS. BY FLORIS OSMOND AND J. E. STEAD, D.MET., F.R.S. "Of all the hooks [sic] which have dealt with this subject in its many aspects, surely this one remains supreme." — Chemical World.

Pause on that. A blacksmith in 1916 — a man whose predecessors had for four thousand years judged steel by its color, its sound on the anvil, and the shower of sparks it threw on a grinding wheel — was being told he ought to polish a specimen, etch it with reagents, and examine its grain structure under a microscope. The book recommends 195 photo-micrographs as study material.

This was not crank advice. Floris Osmond, working in France in the 1880s and 90s, had essentially founded the discipline we now call metallography. He identified the crystalline phases of iron (austenite, martensite, pearlite — names still on every materials-science syllabus) decades before X-ray diffraction confirmed them. Stead extended the work in Britain. By 1916, they were trying to push their microscopes down out of the university laboratory and into the village forge.

It largely didn't take. The village smith was already an endangered species; within a generation, mass-produced pressed steel and the automobile finished him off. The microscope migrated instead into the quality-control lab of the steelworks, where it remains today — every automotive supplier and aerospace foundry still runs metallographic samples on essentially the workflow Osmond and Stead codified.

What's genuinely forgotten is the ambition of that moment: the idea that a tradesman standing at a coal fire should also be a scientist with a polished puck of steel and a bottle of nitric-acid-in-alcohol at his elbow. Modern readers may recognize the pattern. It's the same argument being made today about auto mechanics reading OBD-II data streams, or farmers interpreting soil-microbiome assays, or line cooks running sous-vide with a thermocouple. Every generation has its "the trades must now also be laboratories" book. In 1916, for the smiths, the answer turned out to be: no, the laboratory will simply eat the trade.
