If you have once seen a picture, says Emerson somewhere, never look at it again. He means that hours of insight are so rare that a really high and satisfying experience with a book, picture, landscape, or other object of beauty is to be accepted as final, a favor of Providence which we have no warrant to expect repeated. If you have seen a thing, therefore, really seen it and communed with the soul of it, let that suffice you. Attempts to live the hour over a second time will only result in failure, or, worse yet, will cast a shadow over what ought to have been a permanently luminous recollection. There is a modicum of sound philosophy in the advice. We must take it as the counsel of an idealist, and follow it or not as occasion bids. The words of such men, as one of them was given to saying, are only for those who have ears to hear. We may be sure of one thing: poems, landscapes, pictures, and all other works of art (art human or superhuman) are never to be exhausted by one look, or by a hundred. If a man is good for anything, and the poem or the landscape is good for anything, he will find new meanings with new perusals. In other words, we may turn upon Emerson and say: “Yes, but then, you know, we never _do_ see a picture--a picture that _is_ a picture.” As was related a week ago, I spent the 12th of October on the North Shore. I brought back the remembrance of a glorious piece of the world’s beauty. In outline, I had it in my mind. But I knew perfectly, both at the time and afterward, that I had not really made it my own. I had been too much taken up with other things. The eye does not see the landscape; nor does the mind see it. The eye is the lens, the mind is the plate. The landscape prints itself upon the mind, through the eye. But the mind must be sensitive and still, and--what is oftener forgotten--the exposure must be sufficiently prolonged. The clearest-eyed genius ever born never saw a landscape in ten minutes. On all grounds, then, I was entitled to another look. And this time, perhaps, the Lapland longspurs would be there to be enjoyed with the rest. I would go again, therefore; and on the morning of the 18th, long before daylight, judging by the quietness of the trees outside that the wind had gone down (for wind is a serious hindrance to quiet pleasure at the seashore in autumn, and visits must be timed accordingly), I determined to set out in good season and secure a longish day. Venus and the old moon were growing pale in the east when I started forth, and three hours afterward I was footing it through Ipswich village toward East Street and the sea.
