Public Rehearsal of Tech, Pageant

The first event in the dedication exercise of the new M.I.T. buildings will be a dress rehearsal of the great masque and pageant on Saturday. This will be the public's only chance to see the performance of which Professor Ralph Adams has had general direction, and which has been developed by several other artists.

For the Masque Mr. Ecker has composed some original numbers. The opening chorus where the struggling unorganized elements are in tumult is illustrated by a chorus "Chaos," Which the dissonances so much loved by the modern composers are eminently fitted to portray.
