There--you don't quite understand that piece of political economy.

Indeed, it is only in the last two or three years that older heads than yours have got to understand it, and have passed the wise new salmon laws, by which the rivers will be once more as rich with food as the land is, just as they were hundreds of years ago.

But now, look again at the river.

What do you think makes it so yellow and muddy?
Dirt, of course.
And where does that come from?
Off the mountains?
Yes.

Tons on tons of white mud are being carried down past us now; and where will they go?
Into the sea?
Yes, and sink there in the still water, to make new strata at the bottom; and perhaps in them, ages hence, some one will find the bones of those sheep, and of poor Mr.Pig too, fossil-- And the butter firkins too.
