unnlrag up each eide of the bell and directly oppositeeach other are two openings which meet in the center of the topof the bell. From this point a pipe runs down into the maintrap to a point a short distance below the bottom of the bell.The trap being filled with water, the supply pipe is turned onin the tank. As the water rises the bottom of the bell is sealedand then the two openings in the aide. When the seal is completethe pressure of the air in the bell forces the water down in thetrap, and finally brings the siphon into operation in just thesame manner as in the case of the Rhoads William. The water inthe tanks is drawn down to the bottom of the bell, the siphon isvented and prepared for tlie next operation. Probably the most serious objection to this form of siphon,is the fact that the auxiliary blow off trap is directly exposedand will admit any foreign matter that might drop into the trapand be carried over by the siphon. Should thie trap becomeclogged the siphon is useless.

A halfcircle of cast iron pipe is set in the tank, both ends being flushwith the floor and one end being set close to the long leg of thesiphon* The bell sets upon the floor of the tank and is held inplace by its own weigjit. This bell is set in such a positionthat it covers the end of the half circle of pipe next to thelong leg of the siphon* Between the two legs of the siphon is oastan iron web, along side of which is a wrougjit iron blow off trapin the form of a loop* The operation of the siphon is the sarne as that of theRhoads William or Walker* The only added feature of the siphon is the half circle ofpipe* The sii^on continues to operate until the water is drawndown to the level of this pipe. This device removes all thewate
