April 8. [...] When the question of the protection of birds comes up, the legislatures regard only a low use and never a high use; the best-disposed legislators employ one, perchance, only to examine their crops and see how many grubs or cherries they contain, and never to study their dispositions, or the beauty of their plumage, or listen and report on the sweetness of their song. The legislature will preserve a bird professedly not because it is a beautiful creature, but because it is a good scavenger or the like. This, at least, is the defense set up. It is as if the question were whether some celebrated singer of the human race--some Jenny Lind or another--did more harm or good, should be destroyed, or not, and therefore a committee should be appointed, not to listen to her singing at all, but to examine the contents of her stomach and see if she devoured anything which was injurious to the farmers and gardeners, or which they cannot spare.
April 15 [...] The bay-wing now sings--the first I have been able to hear--both about the Texas house and the fields this side of Hayden's, both of them similar dry and open pastures. I heard it just before noon, when the sun began to come out, and at 3 P. M., singing loud and clear and incessantly. It sings with a pleasing deliberation, contrasting with the spring vivacity of the song sparrow, whose song many would confound it with. It comes to revive with its song the dry uplands and pastures and grass-fields about the skirts of villages. Only think how finely our life is furnished in all its details,--sweet wild birds provided to fill its interstices with song! It is provided that while we are employed in our corporeal, or intellectual, or other, exercises we shall be lulled and amused or cheered by the singing of birds. When the laborer rests on his spade to-day, the sun having just come out, he is not left wholly to the mercy of his thoughts, nature is not a mere void to him, but he can hardly fail to hear the pleasing and encouraging notes of some newly arrived bird. The strain of the grass finch is very likely to fall on his ear and convince him, whether he is conscious of it or not, that the world is beautiful and life a fair enterprise to engage in. It will make him calm and contented. If you yield for a moment to the impressions of sense, you hear some bird giving expression to its happiness in a pleasant strain. We are provided with singing birds and with ears to hear them. What an institution that! Nor are we obliged to catch and cage them, nor to be bird-fanciers in the common sense. Whether a man's work be hard or easy, whether he be happy or unhappy, a bird is appointed to sing to a man while he is at his work.
