you'd think his footprints would still show. By the appearance of this dust, there hasn't been any one in the tower for at least a year."
"Perhaps the dust collects more quickly than we think. It may have covered his footprints over even within a couple of weeks."
An inspection of the ground floor revealed the fact that there was no place where the loot could have been hidden, save under the stairs, and there was nothing in that place of concealment. Accordingly, the Hardy boys ascended to the next floor, finding themselves in a room as drab and bare as the one they had just left. Here again the dust lay heavy and the murky windows were thick with cobwebs. There was an atmosphere of age and decay about the entire place. It seemed to have been abandoned for years.
"Nothing here," said Frank, after a quick glance around. "On we go."
They made their way up to the next floor, after again poking about under the stairs, but again without success.
The next room was a duplicate of the first. It was bare and cheerless, deep in dust. There was not the slightest sign of a hiding place. Much less was there any indication that another human being had been in the tower for years.
"Doesn't look very promising, Joe. Still, he may have gone right to the top of the tower."
