To get rid of the wild dogs, Karana decides she needs three things. What were they?

Weapons.... a bow, arrows, and a spear.

I thought about these things for two days and on the third night when the wild dogs returned to the rock, I made up my mind that no matter what befell me I would make the weapons. In the morning I set about it, though I felt very fearful.

I wished to use a sea elephant's tusk for the tip of the spear because it is hard and of the right shape. There were many of these animals on the shore near my camp, but I lacked a weapon with which to kill one. Our men usually hunted them with a strong net made of bull kelp, which they threw over an animal while it slept. To do this at least three men were needed~ and even then the sea elephant often dragged the net into the sea and got away.

I used instead the root of a tree which I shaped into a point and hardened in the fire. This I bound to a long shaft, with the green sinews of a seal I killed with a rock. The bow and arrows took more time and caused me great difficulty.
