"Remember Glennie?" cried Matt. "Well, I guess I do. Why, he went around South America with me in a submarine."
"Representing the government, wasn't he?"
"Yes."
"Well, Glennie's my cousin, and he wrote me all about you and that trip in the submarine. So that's where the coincidence comes in. He watched your work with the submarine for the government, just as I'm to watch your work with the aëroplane. Give us your hand, Motor Matt! I feel as though we were old friends."
Matt was delighted. It was one of those meetings which sometimes happen, and which make a fellow overjoyed with the occasional workings of fate. McGlory, Black, and Ping were introduced, and then Matt took the lieutenant off by himself and narrated the events that had taken place, and which had led up to the villainous work of Siwash Charley.
Lieutenant Cameron was properly indignant.
"Siwash Charley's a whelp," he averred, "and this Murgatroyd is a thoroughbred scoundrel. But the aëroplane seems to be safe, and you'll have no further trouble with those villains. From this on, Motor Matt, you and your friends and the Traquair aëroplane are under the protecting wing of Uncle Sam. We'll have the flying machine guarded, and you and your friends will stay at the fort with us. There's only a handful of boys at Totten, now, but we're more than enough to look after Siwash Charley."
The lieutenant rode over to the wagon.
"Jake," said he, "you'd better drive back with that machine."
"That's what I was calculatin'," grinned Jake. "Somebody hand up my whip."
