It is quite unnecessary to say that Paul and John Ross read the foregoing article with the keenest pleasure the night they reached home from the hangar and found their mother just finishing its perusal. Naturally Mrs. Ross felt all of the average mother's anxiety at the thought that her sons would be exposed to the perils such a long journey would invite, but on the other hand she was very proud to think their talents had placed them in such an honored position.  It had only been an evening or two before that Mr. Giddings, in company with his son Robert, had called at the Ross homestead, and after a long conference with the boys as to the suitability of the new Sky-Bird II for making a world cruise, had taken his departure with his mind fully made up as to how he should meet the rival paper's challenge.
