The Stonemason's Discipline
Dr. Gene A Constant · the whole book, free to read here
- Structural integrity.
- Geometric precision.
- Aesthetic legacy.
Brick, stone, mortar and drainage, taught the way a patient foreman would: from arriving on the site to arches, dry-stack walls, fireplaces, veneer, permeable paving and restoration. Read it, listen to it while your hands are busy, and practice reading a failure back to its cause before you repair anything.
Safety first, every time. Cutting brick and stone makes silica dust, a lifelong injury you cannot undo: wear a fitted respirator rated for silica, eye and hearing protection. Lift with a barrow or sled, not your back. Near a foundation or on a real retaining wall, do not guess at footing design. Inside a firebox, only heat-rated materials belong. Check your local code.

The Certificate of Comprehension
Thirty questions drawn from all twelve lessons, graded on our server; you need 80% to pass. A pass prints a serial-numbered certificate with a link anyone can use to verify it. It records comprehension of the book. It is not a trade licence or an industry credential.
Sit the exam Open the class pageThe Cause Bench
Eight failures from the book. Read what you see and what was done, then tap the cause. A wrong pick tells you why that cause is not the one, so you learn from every tap.
This bench is practice, not a certification. The certificate comes from the class exam above.
