Paragraph- Sent 1: The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round.
Sent 2: By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows.
Sent 3: My search had shown me nothing fresh.
Sent 4: Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars.
Sent 5: I had not, if I remember rightly, been into them since my hasty search on the evening of the attack.
Sent 6: For, perhaps, the half of a minute, I hesitated.
Sent 7: I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest.
Sent 8: Great, gloomy caverns of places, unlit by any ray of daylight.
Sent 9: Yet, I would not shirk the work.
Sent 10: I felt that to do so would smack of sheer cowardice.

Question: Why did he hesitate before going into the cellar?.
answer:
It's huge and weird.
