This is the way in which he (poet) did his work. He used to go out with a pencil and a tablet and note what struck him...and make a picture out of it...But Nature does not allow an inventory to be made of her charms! He should have left his pencil behind, and gone forth in a meditative spirit; and, on a later day, he should have embodied in verse not all that he had noted but what he best remembered of the scene; and he would have then presented us with its soul, and not with the mere visual aspect of it.
