 Why does Mr. Henderson want to work for the children?
It is an uneasy privilege then, at least sometimes, to teach my old-fashioned brand of science to these children of a new age. "It has the purpose," I told her, "of teaching the members something about commerce and industry. They manufacture simple compositions like polishing waxes and sell them from door-to-door. Some groups have built up tidy little bank accounts which are available for later educational expenses." Mr. McCormack is going to put up fifty dollars to buy any raw materials wanted This was to be our headquarters and factory for the summer—a roomy unused barn belonging to the parents of one of the group members, Tommy Miller.
 The children are incredibly successful.
 The parents of the children work for the Commission and Henderson is scared of the Commission.  He needs the money to pay for his mortgage.  He does not want to work for the children. The children will work for Mr. Henderson.  The children are incredibly successful.
