Dipping the Farm Flock. 



The dipping tank can not only be used for sheep but for hogs and 

 young calves as well, so that the entire outlay need not be charged up 

 against the sheep. Dipping is especially valuable in overcoming the 

 ravages of scab, lice and ticks, but it will also prove beneficial in pre- 

 venting eye, nose and mouth troubles. If regular dipping is practiced 

 it will not only prevent to a large extent may of the ravages common to 

 sheep, but it will maintain the flock in a much better state of general 

 healthfulness. 



FIG. 11 The Station farm dipping tank in use. 



There are a number of proprietary dips on the market which can be 

 used successfully and at a moderate cost. Standard dips of this kind 

 are generally used in the proportion of one part of dip to forty parts of 

 water, making a two and one-half per cent solution. The best and most 

 effective time to dip sheep is in the spring, about ten days after shear- 

 ing. It will take much less of the solution and be far more effective. 

 Dipped in this way the sheep can be put through the tank very rapidly, 

 while if they are dipped for scab or while the wool is on they should be 

 immersed several times and held under excepting the head from one and 

 one-half to two minutes. In case of sheep scab the scabs should all be 

 loosened, so that the dip will thoroughly penetrate the exposed parts. 



The dipping tank can be made of wood, galvanized iron, or concrete. 

 The concrete tank will last indefinitely and is the most economical type
