"Well, come on," suggested Ned. "If there's anything there, we'll have a peep at it."
His idea was not to try to see what Tom was evidently endeavoring to conceal, but it was to observe whence Harry had made his observation, and be in a position to tell Tom to guard against unexpected lookers-on from that direction.
During the walk back along the course over which Harry had run so rapidly a little while before, Ned and the boy talked of what the latter had seen.
"Do you think it could be some new kind of elephant?" asked Harry. "You know Tom Swift brought back a big giant from one of his trips, and maybe he's got a bigger elephant than any one ever saw before."
"Nonsense!" laughed Ned. "In the first place, Tom hasn't been on any trip, of late, except to Washington, and the only kind of elephants there are white ones."
"Really?" asked Harry.
"No, that was a joke," explained Ned. "Anyhow, Tom hasn't any giant elephants concealed up his sleeve, I'm sure of that."
"But what could this be?" asked Harry. "It moved just like some big animal."
"Probably some piece of machinery Tom was having carted from one shop to another," went on the young bank clerk. "Most likely he had it covered with a big piece of canvas to keep off the dew, and it was that you saw."
"No, it wasn't!" insisted Harry, but he could not give any further details of what he had seen so that Ned could recognize it. They kept on until they reached the hill, at the bottom of which was the Swift home and the grounds on which the various shops were erected.
