Thisstick is pushed through an opening in the side of the pan intowhich it fits tightly, and then partly withdrawn. A small quan-tity of the contents of the pan remains in the hollow space, andthis the sugar boiler removes and places on a piece of clearglass. On holding it up to the light, he sees exactly how thecrystallization of the sugar is progressing, and by observingand feeling the crystals, he is enabled to control the boiling per-fectly. When he concludes that the evaporation is complete andthe massecuite of the proper consistency, the pump is stoppedand the vacuum broken by opening a valve near the top of thepan, admitting the outside air. The foot valve is then opened.
