as are also the receiving and forcing yards. The sheep enter the bath 

 by a slide leading straight from the end of race, and no decoy pen is 

 provided for. 



Specifications of material, &c., may be worked out from those given 

 relative to No. 6. 



No. 6.— Dip constructed by Mr, Wallace, at Drummartin Estate, 

 near Elmore. 



Material. — Brick grouted in cement, faced with cement mortar, three 

 of sand to one of cement. 



Dimensions. — Bath — length, 40 feet at top; 26 feet at bottom to 

 the foot of ramp or "walk-out"; width, inside, 22 inches at top, 

 10 inches at bottom; depth, 5 feet at the back, 4 feet at foot of ramp. 



Construction. — Walls of bath 4 inches, i.e., one brick in thickness, 

 with a pier or column of three bricks square built in each wall, 13 feet 

 from the back end, to strengthen it; building iron is laid in every 

 fourth course, and a good packing of clay or other solid material rammed 

 in behind to support walls. 



The wall at the back, and for 4 feet of side opposite the slide-in, 

 is built 3 feet above the level of the ground. Along the top of the wall, 

 all round, one brick is placed lengthways, at right angles, to form a 

 coping. On the floor of bath the bricks are laid on edge on good sand 

 foundation. 



The ramp is faced, or overlaid, with 3 inches of cement mortar 

 (three in one), and formed in slats or corrugations to give the sheep a 

 good foothold in walking out; it is also widened slightly towards the 

 top. 



Draining Yards. — Two yards, each 20 feet x 20 feet, floor formed of 

 bricks laid on edge on good sand foundation, grouted and faced with 

 1 inch of cement mortar, as before mentioned. The floor has a slope 

 of 3 inches in 10 feet from the sides to the centre of each yard, and 

 a slope from the back of the yards towards the bath of 1 inch in 10 feet. 

 The liquid drains into two settling pits 2 feet in depth by 2 feet x 

 1 ft. 3 in., from which it runs through strainers placed at the entrance 

 to channels near the top of the pits, and thence by pipes or channels 

 under the surface to the bath, which it enters 8 feet from the " walk- 

 out." 



These pits can be frequently skimmed of droppings, pieces of wool, 

 &;c., and baled out when necessary, thus to an extent preventing the dip 

 from becoming fouled. 



A gate is hung on end of fence dividing the two yards, to fasten 

 back to a post at either side of walk-out, and so that the yards may be 

 used alternately. 



Entrance to dip is by a race leading from receiving yards, 10 feet 

 long, 1 ft. 3 in. in width, inside measurement, with slide 3 ft. 6 in. 

 on the side of the end abutting bath. The slide, which is placed at an 

 angle of about 45 degrees, is constructed of hardwood, aiid is kept well 

 greased or wet when the sheep are going through.
