It has been my aim in the thirty-nine chapters of the three books in this series to carry my readers through the weeks of all the school year, not however as with a calendar, for that would be more or less wooden and artificial; but by readings, rather, that catch in a large way the spirit of the particular season, that give something definite and specific in the way of suggestions for tramps afield with things to look for and hear and do. Naturally many of the birds and animals and flowers mentioned, as well as woods and aspects of sky and field, are those of my own local environment--of my New England surrounding--and so must differ in some details from those surrounding you in your far Southern home or you on your distant Pacific coast, or you in your rich and varied valley of the Mississippi, or you on your wide and generous prairie. But the similarities and correspondences, the things and conditions we have in common, are more than our differences. Our sun, moon, sky, earth--our land--are the same, our love for this beautiful world is the same, as is that touch of nature which we all feel and which makes us all kin. Wherever, then, in these books of the seasons, the things treated differ from the things around you, read about those things for information, and in your journeys afield fill in the gaps with whatever it is that completes your landscape, or rounds out your cycle of the seasons, or links up your endless chain of life. While I have tried to be accurate throughout these books, still it has not been my object chiefly to write a natural history--volumes of outdoor facts; but to quicken the imaginations behind the sharp eyes, behind the keen ears and the eager souls of the multitude of children who go to school, as I used to go to school, through an open, stirring, beckoning world of living things that I longed to range and understand. The best thing that I can do as writer, that you can do as teacher, if I may quote from the last paragraph--the keynote of these volumes--is to “go into the fields and woods, go deep and far and frequently, with eyes and ears and all your souls alert.” MULLEIN HILL, May, 1912 THE SPRING OF THE YEAR CHAPTER I “SPRING! SPRING! SPRING!” Who is your spring messenger? Is it bird or flower or beast that brings your spring? What sight or sound or smell spells S-P-R-I-N-G to you, in big, joyous letters? Perhaps it is the frogs. Certainly I could not have a real spring without the frogs. They have peeped “Spring!” to me every time I have had a spring. Perhaps it is the arbutus, or the hepatica, or the pussy-willow, or the bluebird, or the yellow spice-bush, or, if you chance to live in New England, perhaps it is the wood pussy that brings your spring!
