===== If you want to use these as study references or sketch from them, here’s the quick mental overlay: =====
# Ames Building photos - Treat the outer granite walls as massive structural shells. - Interior: a grid of iron or heavy timber carrying floors; walls do gravity work and much of the lateral work.
# Steel-frame skeleton photo - Imagine the same mass of a Boston 10–12-story office block, but the stone becomes just a veneer hung off this cage. - Large window openings and thinner piers become possible, because the frame is doing the heavy lifting.
# Masonry-under-construction photo - Good for understanding the sequence: foundations → lower walls → floors → upper walls, with temporary shoring and staging.

If you’d like, I can:
* Put together annotated line drawings based on these (e.g., a Boston 1890 section: load-bearing stone vs. 1895 steel frame + stone veneer), or
* Help you design a few period-accurate cutaway diagrams for a talk or article you’re working on.
