<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">exchequer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that exchequer can be written as treasury)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for treasury that I've seen before include "The funds of a state" , "Place where great valuables are stored" , "Government finance department" , "British Department of Finance" , "The funds available to government" .)
