In regards to a mythical brick path. I recently worked on an historic
urban site in Knoxville Tennessee. On this site was a large segment of
19th century brick pavement. This pavement was not impervious to backhoe
damage but was extremely resilient and made an excelent demarcation of the
earlier deposits. I also have spent much time on a farm and know something
of the "earth-turning" process. An average plow would have an extremely
difficult time in disturbing any sort of set in bricks. If the bricks were
more than 15-20 centimeters below the surface, most likely the plow would
just "skip-over" the bricks. This is a tendency for plows so as not to get
them irrevocably hung-up on an extremely large rock or root. Loosely set
in bricks or randomly placed bricks would be significantly disturbed as to
their orientation but a significant amount of grinding and wear, in my
opinion, would not take place. I think the loosely set in bricks would
just tumble around in the plow zone. Occasionally I find bricks in fields
near my home which I suspect are part of a chimney fall. The tightly set
in bricks as at the urban site I worked at would have a few plow scars but
likely would not be moved around very much.
