t 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 thewater from the tank which is a very good feature* The objectionis the same as for any double trap siphon* The small trap isalways exposed to clogging. In this particular case the blow offtrap is made of wrought iron whose life is imich less than thatof the cast iron in the main siphon. Plate /Vol/:

-9- THE DE LA HUNT SIPHON. The De La Hunt siphon, shown in Plate VI. is oonatructedand works on rauch the same principle as the other double trapsiphons already described. It consists of a bell, main trap andan auxiliary blow off trap. The only material difference liesin the fact that the blow off trap is made adjustable so thatdifferent discharging heights may be obtained. The objections to this style of siphon are the same asthose already mentioned for double trap siphons. The life of theauxiliary is much shorter than that of the main trap, and beingembedded in the concrete is impossible to get at without removingthe entire siphon. DE LA HUNT SIPHON.
