When the lowest nest was built and the four long pure white eggs were laid in it, Mr. and Mrs. Swift were a very proud young couple. The nest was so thin that one could see the eggs through it quite plainly, but it was exceedingly stout and firm. It was not a soft nest, and it had no real lining, although Mrs. Swift had laid in one especially perfect grass blade "to give it style."
That grass blade may be seen to this day by any one who cares to look at the nest as it lies in a cabinet in the house. It was the only nest in the chimney which had anything but twigs in it, and some people wondered at Mrs. Swift's taste. One stout elderly mother Swift said "she supposed it was all right, but that she had never done such a thing and her children had turned out all right." However, young Mrs. Swift smiled in her pretty way and did not talk back.
When they were planning for the four children whom they expected, Mrs. Swift spoke of how patient they would have to be with them, but Mr. Swift said: "They must be brought up to mind! If I tell a child once to do a thing, that is enough. You will see how I bring them up." Then he ruffled up his feathers, puffed out his throat, and looked very important.
They did most of their visiting in the beautiful night-time, for it is a custom among their people to fly and hunt and visit in the dark, and rest by day. Their busiest time is always just before the sun comes up, and so it happened that the Little Boy who slept in the room below did not often hear the rumbling noise in the chimney as they flew in and out. When they were awakened he slept quietly in his snug little bed, and as he was awakening, and stretching, and getting his dimples ready for the day, the Swifts were going to sleep after a busy night.
When the baby Swifts broke their shells and were seen for the first time by their loving father and mother, Mr. Swift was surprised to find how small they were. Mrs. Swift murmured sweet words to them and worked as hard as her husband to find them food. There were now so many mouths to be fed that they flew by day as well as by night, and often the Little Boy in the room below thought he heard distant thunder when it was only the Swifts coming down the chimney with food for their babies. All sorts of tiny winged creatures were brought them to eat, for Swifts catch all their food as they fly, and that means that they can feed upon only such creatures as also fly.
