Query: Conserving Integrals in [Non-]Metric Theories of Gravitation   In this work I present location to first mentioning to result of Robert
Geroch Preprint deals with conserving quantities of metric gravitational
theories They are constructed from Killing vector fields (if any exists) and
symmetric tensors of arbitrary rank with vanishing divergence I also suggest
alternative approach by introducing spinorial fields allowing to construct
conserved integrals of energy-momentum etc
