Some general results on spatially homogeneous cosmological models are obtained in the general scalar-tensor theory proposed by Nordtvedt and Barker. Cosmological equations for a Bianchi type-I empty universe are solved and the behavior of the model is discussed. It is found that the universe expands from the initial singularity of zero volume and then contracts back. There is a significant difference between the nature of the singularity in this model and that in the corresponding Kasner universe in Einstein's theory.
