44 THE MINDS AND MANNERS 



"No; we would rather have you build over the plank." 

 The next night more mud and sticks piled against the fence 

 said to us, 



"We really insist upon building it here!" 



We made a second clearance of their materials, sajring in

 letters, colors and tones, the calendar and the dial, that he 

 could count and read, deal with decimals and fractions, speU
