Returned to camp, and struck down to the place where the tor- 

 toise signs were. Reached it at 4 :30 P. M., and laying down 

 the pack commenced searching, and in a portion of the 

 "island" of old lava found a still older flow where there was 

 considerable soil. Here I found a tortoise trail which had 

 been travelled the day before. I followed this, and soon found 

 in the trail a rock which had been used for the same purpose 

 that rocks in similar places on Tagus Cove Mountain have 

 served ever since the whalers carried off all the female tor- 

 toises. Going on some distance farther the old male was 

 found slowly feeding on grass near the trail. Getting my pack, 

 I ate supper and skinned the tortoise by moonlight. Starting 

 with him next morning, I reached the shore at 4 :30 P. M.
