“Bring me the opera-glasses from the little bag that is with my hat and gloves,” she said softly to Sarah Barnes. Then, motioning the children to keep still, she crossed the road to a point where, the sunlight falling behind her, she could look up at the wires without becoming dazzled, but as she did so the entire flock left the wires, and wheeling went down over the corn-field toward the reeds and low woods that bordered the mill-pond. “You were quite right, Tommy,” said Gray Lady, as they still stood looking at the wires in the hope that the birds might return; “there were not only three but four kinds of Swallows in that flock. The birds with the slightly forked tails, beautiful shining steel-blue and green cloaks, and satiny white underparts are Tree Swallows that do not nest near here, but stop with us on their spring and fall journeys, and the others that you did not notice, because in the distance they look somewhat like Barn Swallows, except that they lack the forked tail, are Cliff or Eaves Swallows, as they are called in this part of the country, where they are rather uncommon. “Now we will go in and I will ask Tommy Todd, who writes very clearly, to put on the board the names of these four Swallows, and the particular thing about them that will help you to tell them apart. “No, I am afraid that they are not coming back,” said Gray Lady, after they had waited a couple of minutes more, “and they may all leave us suddenly any day now, though the Barn Swallow often stays into October and the White-Breasted almost to November.” A wagon loaded with rye straw and drawn by a yoke of oxen came creaking up the hill and paused on the level place in front of the school. The teamster was Jared Hill’s grandfather,—the man who did not believe in play or playthings. As his far-sight was rather poor, he did not notice that the lady with the children was not Miss Wilde. “Wal, teacher,” he called, as he leaned against his load, and tried in vain to discover the object at which the group was gazing, “what’s up thet there pole, a possum or a runaway hand-orgin monkey, or mebbe it’s the balloon got loose from Newbury Fair grounds?” “No, nothing so unusual as that; we have been watching the flocking of the Swallows,” said Gray Lady, her silvery voice sounding clearly even in these deaf ears. “Swallers!—out er school watchin’ Swallers?” exclaimed old Mr. Hill, taking the long straw that he was chewing from between his teeth in questioning amazement. “Shucks! what’s Swallers good fer, anyhow? Gee—haw, Cain! Shish, Abel! We’d best move on; I reckon this isn’t any place fer folks with something to do!” And thus addressing his oxen, the load went slowly on. With the mischievous twinkle still lingering in her eyes, Gray Lady asked Tommy Todd to go to the blackboard as soon as the children settled down to their work again, and this is what he wrote at Gray Lady’s dictation:—
