As sure as I lay there, it was something on the roof! It sounded like something crawling slowly and by fits and starts along the gutter just above the dormitory.

Sometimes it seemed to spring upwards, as though attempting to reach a higher position, and then sullenly slip down and proceed on its crawling way.
Yes, without doubt Fergus had told the truth! Suddenly a voice in a loud whisper at the other end of the dormitory exclaimed-- "Listen! I say, listen!" It was Lamb's voice.

There was at least some comfort in knowing that I was not the only one awake.
With a desperate effort I sat up in my bed and replied-- "Oh, Lamb, what is it ?" His only reply was a gasp, as the noises recommenced.

The body, whatever it was, seemed to have dragged itself forward, so as to be now just over our heads.

The ceiling above us went right up into the roof, and I could distinctly hear a rustling sound against the tiles, followed by an occasional upward leap, sometimes almost wild in its eagerness.
How could I mistake these sounds?
The chimney was immediately above us, and it was towards this goal, as I well knew, that the hapless and legless Bubbles was destined fruitlessly to aspire.
