Hydroplane
.
The inhabitants of Slocomb-on-Sea were greatly excited over the visit of a certain flying man.
All the town turned out to see the flight of the wonderful hydroplane, and, of course, Dobson and his family were there.
Master Tommy was in good form, and informed his father that Englishmen made better airmen than Scotsmen and Irishmen because they are not so heavy.

"How do you make that out?" asked Mr. Dobson.
"Well, you see," Tommy replied, "it is true that in Ireland there are men of Cork and in Scotland men of Ayr, which is better still, but in England there are lightermen."

Unfortunately it had to be explained to Mrs. Dobson, and this took the edge off the thing.
The hydroplane flight was from Slocomb to the neighbouring watering-place Poodleville—five miles distant.
But there was a strong wind, which so helped the airman that he made the outward journey in the short time of ten minutes, though it took him an hour to get back to the starting point at Slocomb, with the wind dead against him.
Now, how long would the ten miles have taken him if there had been a perfect calm?
Of course, the hydroplane's engine worked uniformly throughout.
