A carpenter made a door and made it too large; he cut it again and cut it too little; he cut it again and made it fit.
A wagoner, being asked of what his load consisted, made the following (rather indirect) reply:
Three-fourths of a cross, and a circle complete;
An upright, where two semi-circles do meet;
A right-angled triangle standing on feet;
Two semi-circles, and a circle complete.
What is it?
