instruction, and so far from affecting the big- wig, is not 

 afraid to learn anything from any one. The notes he 

 takes are amazing ; many a one he has had from me 

 to-day. He is very helpless in the field without 

 people to point things out to him ; quite inexperienced 

 and unable to see his way either physically or geologi- 

 cally. He could not map a mile, but understands all 

 when explained, and speculates thereon well.' ' He 

 wore spectacles half the day, and looked ten years 

 older [in consequence]. Logan says it is vanity that 

 prevents his always doing so. I think it is custom, 

 and perhaps his wife.'
