He looked about the laboratory.

There were the beams and crossbeams, and the box would probably just fit into one of the shadowy interstices between two of the latter.

But they were twenty feet from the ground, he had no ladder, and if there had been one at hand he could not have mounted it yet.

No one would think of it as a place for hiding anything, and it would not be emptied till it was quite full, several months hence.
