“What are those stars near Job’s Coffin?” asked Billy.

“That is Aquilla,” answered Mrs. Remington.

“Now let me get these down straight,” came from Billy. “First, that ‘W’ is Cassiopaeia. Next to her—what are those four big stars like a square?”

“It is called the Great Square of Pegasus,” replied Mrs. Remington. “Then comes Aquilla and Job’s Coffin, and above us you find Lyra.”

“Look! What is that large star in the northeast—it is low down on the horizon but it is rising fast?” cried Dudley.

Every one turned to gaze at the beautiful twinkling star that seemed to sway in the sky. In fact Billy denied it was a star.

“Any one can see with half an eye that that’s a fire-balloon!” argued he.

However, it proved itself to be a star and finally, Mrs. Remington and Fred identified it as Capella and the atmospheric conditions near the horizon accounted for its gyrations.

“But, mother, it is moving east!” cried Elizabeth.

“It is a fire-balloon, ’cause no star travels that way,” added Billy.
