orchard,—­places where one may have many thoughts and not decide anything.  It is a scene which I can not only remember, as I might a vision, but when I will can bodily revisit, and find it even so, unaccountable, yet unpretending in its pleasant dreariness.  When my thoughts are sensible of change, I love to see and sit on rocks which I have known, and pry into their moss, and see unchangeableness so established.  I not yet gray on rocks forever gray, I no longer green under the evergreens.  There is something even in the lapse of time by which time recovers itself.

As we have said, it proved a cool as well as breezy day, and by the time we reached Penichook Brook we were obliged to sit muffled in our cloaks, while the wind and current carried us along.  We bounded swiftly over the rippling surface, far by many cultivated lands and the ends of fences which divided innumerable farms, with hardly a thought for the various lives which they separated; now by long rows of alders or groves of pines or oaks, and now by some homestead where the women and children stood outside to gaze at us, till we had swept out of their sight, and beyond the limit of their longest Saturday ramble.  We glided past the mouth of the Nashua, and not long after, of Salmon Brook, without more pause than the wind.

     Salmon Brook,
     Penichook,
     Ye sweet waters of my brain,
     When shall I look,
     Or cast the hook,
     In your waves again?

     Silver eels,
     Wooden creels,
     These the baits that still allure,
     And dragon-fly
     That floated by,
     May they still endure?

The shadows chased one another swiftly over wood and meadow, and their alternation harmonized with our mood.  We could distinguish the clouds which cast each one, though never so high in the heavens.  When a shadow flits across the landscape of the soul, where is the substance?  Probably, if we were wise enough, we should see to what virtue we are indebted for any happier moment we enjoy.  No doubt we have earned it at some time; for the gifts of Heaven are never quite gratuitous.  The constant abrasion and decay of our lives makes the soil of our future growth.  The wood which we now mature, when it becomes virgin mould, determines the character of our second growth, whether that be oaks or pines.  Every man casts a shadow; not his body only, but his imperfectly mingled spirit.  This is his grief.  Let him turn which way he will, it falls opposite to the sun; short at noon, long at eve.  Did you never see it?—­But, referred to the sun, it is widest at its base, which is no greater than his own opacity.  The divine light is diffused almost entirely around us, and by means of the refraction of light, or else by a certain self-luminousness, or, as some will have it, transparency, if we preserve ourselves untarnished, we are able to enlighten our shaded side.  At any rate, our darkest grief
