<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">bricklayers</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for masons that I've seen before include "They work with stone and brick" , "Stoneworkers - may be free" , "Craftsmen working in stone" , "Workers with stone - may be Free" .)
