E.M. Brock 1958 Aug 11 Arctic Fox Barrow, Alaska about stake number 2.0. From here the fox walked to stake 10.0 following the transect in a straight line and seemingly visiting all the traps. Then, the fox went to the vicinity of stakes 9.0 of transect X and followed the trapline to the area of stake 1.0. Upon checking the two traplines not a single bird (or lemming, if such occurred) remained in the trap. Thirty five traps showed signs of a bird having been eaten from the trap. Also 39 traps were missing - apparently having had birds in them which were carried off by the foxes.
