I see the fishermen floating up and down the river above their nets, which are suspended far out of sight in the water beneath them. They do not know what fish they have got, if any, till after a while they lift the nets up and examine them. In all of us there is a region of sub-consciousness above which our ostensible lives go forward, and in which much comes to us, or is slowly developed, of which we are quite ignorant until we lift up our nets and inspect them. Then the charm and significance of a day are so subtle and fleeting! Before we know it, it is gone past all recovery. I find that each spring, that each summer and fall and winter of my life, has a hue and quality of its own, given by some prevailing mood, a train of thought, an event, an experience,—a color or quality of which I am quite unconscious at the time, being too near to it, and too completely enveloped by it. But afterward some mood or circumstance, an odor, or fragment of a tune, brings it back as by a flash; for one brief second the adamantine door of the past swings open and gives me a glimpse of my former life. One's journal, dashed off without any secondary motive, may often preserve and renew the past for him in this way. These leaves from my own journal are not very good samples of this sort of thing, but they preserve for me the image of many a day which memory alone could never have kept. March 3, 1879. The sun is getting strong, but winter still holds his own. No hint of spring in the earth or air. No sparrow or sparrow song yet. But on the 5th there was a hint of spring. The day warm and the snow melting. The first bluebird note this morning. How sweetly it dropped down from the blue overhead! March 10. A real spring day at last, and a rouser! Thermometer between fifty and sixty degrees in the coolest spot; bees very lively about the hive, and working on the sawdust in the wood-yard; how they dig and wallow in the woody meal, apparently squeezing it as if forcing it to yield up something to them! Here they get their first substitute for pollen. The sawdust of hickory and maple is preferred. The inner milky substance between the bark and the wood, called the cambium layer, is probably the source of their supplies. In the growing tree it is in this layer or secretion that the vital processes are the most active and potent. It has been found by experiment that this tender, milky substance is capable of exerting a very great force; a growing tree exerts a lifting and pushing force of more than thirty pounds to the square inch, and the force is thought to reside in the soft fragile cells that make up the cambium layer. It is like the strength of Samson residing in his hair. Saw one bee enter the hive with pollen on his back, which he must have got from some open greenhouse; or had he found the skunk cabbage in bloom ahead of me?
