Building Cosmos
We Are The Masonry.
Our mission is to provide families and classrooms with curriculum and tools to build cosmos through nature study. Love first, then seek to understand. That is our guiding principle. We say with John Senior, “We can only love what we know because we have first touched, tasted, smelled, heard, and seen.” To that end, we equip families with tools that put kids in direct contact with nature.

Science cannot see without the light of love.
Love first, then seek to understand.
