The engine driver doesn't "hold" with somethings. What are they?

The engine-driver doesn't hold with motor-cars or being ordered about by policemen.

The engine-driver looked very grave and said, "I fear that you have been indeed a wicked toad, and by rights I ought to give you up to offended justice. But you are evidently in sore trouble and distress, so I will not desert you. I don't hold with motor-cars, for one thing; and I don't hold with being ordered about by policemen when I'm on my own engine, for another. And the sight of an animal in tears always makes me feel queer and soft-hearted. So cheer up, Toad! I'll do my best, and we may beat them yet!"
