in Thoreau’s Journal:

The snow falls on no two trees alike, but the forms it assumes are as various as those of the twigs and leaves which receive it. They are, as it were, predetermined by the genius of the tree. So one divine spirit descends alike on all, but bears a peculiar fruit in each. The divinity subsides on all men, as the snowflakes settle on the fields and ledges and takes the form of the various clefts and surfaces on which it lodges.
