At breakfast, there was what Scott called a "panic" and Wilson a "discussion" when it was discovered that a box of biscuit was missing.  Bowers, Scott wrote, was "dreadfully disturbed about it. The shortage is a full day's allowance." 
They found a note from Lt. Evans to say that they had passed safely through on 14th January -- "half a day longer between depots than we have been," noted Scott.
That day they began the descent of the Beardmore, and reached the depot at the upper glacier in the evening.
