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
