"Well done, Mattie," returned the Doctor, patting her on the head. "What a bold little navigator you have grown to be! And boundless sea is quite poetic, too. But as to starting immediately for the South Pole, I do not think we can do so. Perhaps we may, however, and you can rest assured that this sort of life suits me amazingly. I shall favor sailing for the South Pole at the earliest practicable moment." "One thing is certain, and that is, that if we are to be the first to reach the South Pole, we cannot put the expedition off too long," said Will. "Others will imitate us and get there before us if we give them time. We must sail within a few weeks at farthest." "That is true," assented Dr. Jones. "But let us see what Sing has for breakfast." So they entered the dining-room and ate with appetites known to but few terrestrials. And why shouldn't they? Their sanitary environments were perfect; their minds were free from all worldly cares. Ennui and monotony were entirely unknown aboard Silver Cloud, because of the constantly changing panorama of land and sea. There were no heartaches nor burning envies among them, for all were pure-minded and lived as God's children should live the world over. Why shouldn't they be plump and pure and clean, inside and out? "We have all outgrown our clothes," as Dr. Jones expressed it. It was a busy day aboard ship. The whole country was on the lookout for them. The Doctor lowered to within five or six hundred feet of the earth, and the cries of the multitudes that gathered in every town and country corner continually rang in their ears. "Detroit lies directly in our course. Do you see it yonder?" said Professor Gray. "O yes!" cried Mrs. Jones. "I am glad that we shall get a good view of the beautiful city of Detroit. Away to the left is Lake St. Clair, isn't it?"' "Yes," answered the Professor, "and that is the Detroit River. There is the city. Across upon the opposite side is the city of Windsor. Just see the crowds of people! We are being well advertised by telegraph." The squares, streets, and housetops of Detroit were black with people. Such cheering was never heard in that city as when Silver Cloud majestically passed over it. The guns of the fort below the city poured out thundering salutes of welcome. "The poor, dear people!" said Mrs. Jones. "I am so glad that we can give them a few moment's pleasure." "And yet we have done nothing marvelous," returned Dr. Jones. "We have only made use of one of God's laws, and without any hardship or special exertion, have been to the North Pole and back through the kindness of Providence, who furnishes us with extraordinarily favoring gales. The people, as well as ourselves, should give all the glory to God."
