 tion, in pottery will become easier. By lingering steps there was early 

 developed a method of building up vessels by a process differing in part 

 from the spiral. As the parching-bowl had been evolved from the roast-

 molding the food-bowl, as, it will be remembered, the tray had been in

and around the outside of the bottom of an inverted basket bowl (see Fig. 

 524), instead of being pressed evenly into it. As with the cooking pot, 

 so with this; as the coiling progressed it was corrugated, not so much,
