sheep's feet tied and the animal is set down in the bag and hekl the 

 required length of time. 



Heating tanks or boilers are necessary, the size varying with the 

 number of sheep to be dipped. An ordinary iron caldron or kettle 

 will answer the purpose for a small number of sheep. A rectangular, 

 galvanized-iron tank with large heating surface is preferable. Such 

 a tank is set on two parallel walls, the Avails forming the sides, and 

 the bottom of the tank forming the top of the fire box. An opening 

 large enough for the escape of the 

 smoke should be provided at the 

 end opposite that at which the fire 

 is fed. 



When large flocks are to be 

 dipped it is necessary to provide 

 proper facilities for the work and 

 a permanent dipping plant is the 

 only practical solution. 



SELECTING A LOCATION. 



In selecting a location for a dip- 

 ping plant the fact that sheep 

 Avork better upgrade should be 

 given consideration, and if pos- 

 sible the ground used for the re- 

 ceiving corrals and chute should 

 slope up to the end of the vat. 

 The vat itself should be on level 

 ground and preferably extend 

 north and south, with the entrance 

 at the south and the exit at the 

 north, as it has been observed that 

 sheep w^ork better wdien not fac- 

 ing the sun. If the ground selected has good natural drainage it 

 is a point in favor of the location. 



CORRALS AND CHUTES.

One of the important points in constructing a dipping plant is 

 the arrangement of the corrals. Here is where much damage is 

 often caused to the sheep and later attributed to the preparation 

 in which they were dipped. The receiving corral into which the 

 sheep are driven preparatory to dipping, as well as the holding 

 corral into which they go from the draining pens, should each be 

 large enough to hold a full band of sheep, or about 3,000 head. The
