In my experience smell is most important, and I find that there is high authority for the nobility of the sense which we have neglected and disparaged. It is recorded that the Lord commanded that incense be burnt before Him continually with a sweet savor. I doubt if there is any sensation arising from sight more delightful than the odors which filter through sunwarmed, wind-tossed branches, or the tide of scents which swells, subsides, rises again wave on wave, filling the wide world with invisible sweetness. A whiff of the universe makes us dream of worlds we have never seen, recalls in a flash entire epochs of our dearest experience. I never smell daisies without living over again the ecstatic mornings that my teacher and I spent wandering in the fields, while I learned new words and the names of things. Smell is a potent wizard that transports us across a thousand miles and all the years we have lived. The odor of fruits wafts me to my Southern home, to my childish frolics in the peach orchard. Other odors, instantaneous and fleeting, cause my heart to dilate joyously or contract with remembered grief. Even as I think of smells, my nose is full of scents that start awake sweet memories of summers gone and ripening grain fields far away.
