"Do you remember that line, colonel?" and the professor softly whistled a strain in imitation of a bird's note. "The services of our little brothers of the air are exceedingly valuable to the horticulturist. And think of the damage done to arboriculture by the woodborers alone were it not for the help given by the birds. Did you ever notice those borers at work, colonel? Some writer has well described them as animated gimlets. They just stick their pointed heads into the bark and turn their bodies around and around and out pours a little stream of sawdust. The birds would pick off such pests fast enough if people would only give them a chance and not scare them off with shotguns." "Yes, the birds earn their way, there is no denying it, and he is a very stupid farmer who begrudges them the little corn and wheat they take from the fields. The account is more than balanced by the good they do." Then the conversation ceased, for the colonel and his friend moved off to inspect the quince bushes. Pleased by the praises they had bestowed on us for our efforts in cleaning the fruit trees and cornfields of injurious insects, I went to work with new vigor to get out some bugs for my luncheon, and was thus pleasantly employed when a sharp twitter from my mother attracted my attention. "Look, children!" she exclaimed. "Here come our young ladies with some company from the city. Be careful to notice what they have on their heads and then tell me what you think of our sweet, pretty ladies." One of my brothers was swaying lightly on a little swing below me. I flew down hastily and placed myself on the next bough, where I could also get a good view of the ladies as they strolled toward us. They were in a very merry mood and each one seemed striving to say something more arousing than her companions. Miss Dorothy led the way, her arm linked in that of one of the stranger guests. Then followed the others with Miss Katie and Marian hand in hand in the rear. They were all very handsomely dressed, and having just returned from a drive had not yet removed their hats. As they came under the tree where we were perched, which was a favorite spot with Miss Katie, they halted for some time and consequently I had an excellent opportunity to look, as my mother had bidden me. And what did I see?
