That was what put me hopelessly wrong. I began 

 to look for particular objects instead of taking one 

 direction and keeping to it. Whenever a flat-topped 

 thorn, a quaint ant-heap, a patch of tambookie grass, 

 or a forked marula came in sight, I would turn off to 

 see if they were the same we had passed coming out. 

 It was hopeless folly, of course ; for in that country 

 there were hundreds and thousands of such things all

 have given a whoop of delight ; but a chilly feeling
