Stone.

luiliauapolis New?. Jhil Did you know that stone lias sap in it? When it is fresh-quarried we .call it ‘green’ stone. It is not fit be used until jit is thoroughly dried out. Stone fresh and moist from the quarry does not show its defects. If quarried in frosty or wet weather it should be left to thoroughly dry under exposure to the air. If no defects then appear, it can be used with safety, but must be handled with care. The reason that sd much stone cracks in buildings is that it is putin green. When the sap dries out the stone changes condition, and the pressure upon its various surfaces becomes uneven, and breakage results.
