Hereunder is a description and par- 

 ticulars of its construction, kindly su,p- 

 plied by Mr. Farrer, City Engineer, 

 Ballarat : — - 



Diwensions of Bath. — Inside diameter, 

 at top, 9 feet; inside diameter, at bottom. 

 4 feet; depth, 5 ft. 3 in., with a 12-ft. 

 long ramp or " walk-out " ; slope, one m 

 three. 



Draining Yards.- — Two, each 16 feet s. 

 10 feet, with slope towards gutter at outer 

 edge, whence the liquid runs into small 

 settling pits, one on each side, fitted with 

 gully-weil to catch grit and filth, and 

 grating to strain off floating matter, 

 hence only strained liquid gets back to 

 bath. 



The silt and thick liquor so checked is 

 drained away by removing a wooden 

 sluice-gate, which opens the pit to the 

 bottom. When the dip is not in use, this, 

 sluice-gate is left out, so that rain water 

 draining off the pens cannot get into the 

 bath. 



The constructive material is cement 

 concrete, in proportion of six parts gravel 

 lo one of cement for the main part of 

 the work. The inner sides of all walls 

 and bottom are rendered to a thickness 

 of \ inch with two to one cement mortar, 

 finished off with a coat of \ inch thick of 

 one to one cement mortar. 



The walls and floor of bath are both 

 6 inches in thickness. 



The floor of draining yards is 3 inches 

 thick of six to one, as before, faced by. 

 I inch of two and a half to one grit and 

 cement, and formed on good sand founda- 

 tion. 



"Slide-in" above bath top is of 

 timber, lined on bottom with plain sheet 

 iron, about f inch thick. 



Hereunder is given the capacity of bath 

 at different marks, as gauged by tank 

 measurements : ■ — ■
