In the hands of teachers and painters

I pushed into the colour sketch. Chalk. I was reminded of the npr article Thinking too much about chalk, that I didnt have time for at the time I read the title but now I had to make time for it. The npr article also refers to    
Chesterton's essay on chalk.
The first sketch article referred to Pocahontas. I learnt of her yesterday in America: The Story of Us. I heard of her before but didnt know anything about the person.
