What does Mr White mean by, "I should hardly think that he'd come tonight" when discussing the visitor?

Mr. White assumed that the weather and road conditions would keep the Sargeant-Major away.

"I should hardly think that he'd come to-night," said his father, with his hand poised over the board.

"Mate," replied the son.

"That's the worst of living so far out," bawled Mr. White, with sudden and unlooked-for violence; "of all the beastly, slushy, out-of-the-way places to live in, this is the worst. Pathway's a bog, and the road's a torrent. I don't know what people are thinking about. I suppose because only two houses in the road are let, they think it doesn't matter."
