Have you heard that, a year or more ago, an English aviator flew over warships at a height greater than the gunners below could possibly have reached?
And did you know that the aviator succeeded in dropping oranges down the funnels of English warships?
Suppose those oranges had been bombs ?" "The warship would have been sunk," Darrin answered.
"Huerta's bird men might be able to give us a surprise like that," Trent suggested.

"That may prove to be one of the new problems that we shall have to work out." "Oh, I've worked that out already," yawned Danny Grin.

"All we have to do is to equip our funnels with heavy iron caps that will not interfere with the draft of the furnaces, but will keep any oranges---bombs, I mean---from dropping down the funnels." "All right then," added Lieutenant Trent.

"We will consider Dalzell has solved the problem of keeping bombs out of our funnels.

What is Dalzell going to do about contact bombs that might be dropped on deck or superstructure of a battleship ?" "All I can see for that," grinned Dan, "is to call loudly for the police." "One biplane might succeed in sinking all the warships gathered at Vera Cruz," Trent continued.
"Was that the thought that made you look so happy when you came in here ?" Dan asked, reproachfully.
