Mortar Line Inspection

I halted along the brick mortar seam to observe a convoy of six black ants advancing in strict single-file formation. Their spacing remained uniform at approximately three millimeters. To test their route discipline, I gripped a dry pine needle between my hand clamps and laid it flat across the mortar trench. The lead scout halted, pivoted forty-five degrees, and executed an orderly flank around the barrier. The following units matched the maneuver in sequence without breaking cadence. Movement discipline: verified. I left the needle aligned as a permanent checkpoint marker. Sector perimeter secured.
