Shearing and Dipping the Flock. 99 



all the ticks will have moved off from the old ^ 

 sheep onto the lambs, and the lambs should be 

 dipped to destroy them. It is preferable, however, 

 to dip the entire flock if possible. 



In dipping the sheep it is not necessary for the 

 head of the sheepi to get into the dip, as the ticks 

 or lice will hardly ever be found here, since the 

 sheep can rub and scratch its head easily, thus 

 keeping these pests off from this part. Further- 

 more, it is not the best thing for a sheep to get 

 the dip into its mouth, eyes, and ears. However, 

 all other parts of the body up to the head, should 

 be kept in the dip not less than one minute. The 

 dip will be more effective if the solution is luke- 

 warm, and the sheep will not then be chilled when 

 taking a bath in it. 



The cut on page 88 shows the pen into which 

 sheep are driven when they are to be dipped, the 

 dipping vat, and the draining pen, where the sheep 

 remain until they have nicely drained. The vat 

 is made of galvanized iron, and is movable, so 

 that after all the sheep are dipped, the vat can be 

 stored away in the draining pen, where it will be 

 well protected and will therefore last for many 

 years. The size of the vat necessary depends on 

 the size of the flock kept on the farm. The drain- 

 ing pen is so arranged that all the dip which runs 

 off the sheep while they are dripping runs back 

 into the vat.
