eleven o’clock in the morning
The only one of the four windows through which it was possible to look into the court of the fort was that opening at the end of the entrance passage . The outside shutters had not been closed ; but before it could be seen through it had to be washed with boiling water , as the panes were covered with a thick coating of ice . This was done several times a day by the Lieutenant 's orders , when the districts surrounding the fort were carefully examined , and the state of the sky , and of the alcohol thermometer placed outside , were accurately noted . On the 6th January , towards eleven o'clock in the morning , Kellet , whose turn it was to look out , suddenly called the Sergeant , and pointed to some moving masses indistinctly visible in the gloom . Long , approaching the window observed quietly -- `` They are bears ! '' In fact half-a-dozen of these formidable animals had succeeded in getting over the palisades , and , attracted by the smoke from the chimneys , were advancing upon the house . On hearing of the approach of the bears , Hobson at once ordered the window of the passage to be barricaded inside ; it was the only unprotected opening in the house , and when it was secured it appeared impossible for the bears to effect an entrance .
