Still, if it be true, as some of those who were his friends say, that this occasional work was seldom much studied, it becomes unreliable as an indicator of the writer's character. The same hand that in the famous Snob Papers so savagely, and in at least one case so intemperately, satirised types of English society, afterwards produced novels in which fidelity to the essential facts of life is the most conspicuous quality.

Thirty feet on each side of the Indicator (and down in the slate, of course) is a still finer streak—a streak as fine as a pencil mark; and indeed, that is its name Pencil Mark.

I feel that such spying is entirely justified in the circumstances. ...

The direction shown depended, of course, on the drift of the ice relative to the water, and did not take into account any actual current which may have been carrying the ...
