Query: The Energy Distribution of the Bianchi Type I Universe   We calculate the energy distribution of an anisotropic model of universe,
based on the Bianchi type I metric, in the Tolman's prescription. The energy
due to the matter plus gravitational field is equal to zero. This result agrees
with the results of Banerjee and Sen and Xulu. Also, our result supports the
viewpoint of Tryon and Rosen.
