In any case, no attempt shouldbe made to level the bed until eitherleveling wedges or leveling blocks(which will be described later) have beeninserted under the bed at the proper lo-cations. The leveling is effected by ad-justing these wedges or blocks. It isnot essential for concrete work that thesurfaces on the top of the bed be accu-rately parallel with the ways. If the
