THE MANAGEMENT OF SHEEP ON THE FARM. 25 
used to good advantage. Hither before or after shearing is an excel- 
lent time for giving the feet attention. 
DIPPING. 
_ Not only the ewes but the entire flock should be dipped shortly 
alter shearing. They should not be dipped either in extreme hot or 
cold weather, and if the weather is unfavorable immediately after 
dipping, protection should be provided them. If dipping is done 
while the wool is short, it will be more quickly and thoroughly done, 
less material will be required for the dip, and the wool will dry out 
quicker. A satisfactory sheep dip is one that will destroy ticks, lice, 
scab, and all external parasites, and yet will not injure the skin or 
wool. There are a number of good dips upon the market which are

recognized by the United States Department of Agriculture, any one 
of which will give satisfaction if directions are carefully followed. It 
is claimed for some of these that they are an actual benefit to the skin, 
in that they act as a stimulant. 
If the flock is badly infected with scab, it becomes necessary to dip 
twice, with an interval of ten days to two weeks. The second dipping 
destroys those parasites that were in the egg stage at the time of first 
dipping. 
A dipping tank should comprise part of the equipment for every 
flock. They are constructed of galvanized iron, concrete, and wood. 
A galvanized-iron tank, such as can be purchased upon the market, 
has several advantages. It is light enough so that it can readily be 
moved from one place to another. Several farmers can own one in 
partnership. With the ordinary flock a small tank, such as shown 
in figure 7, will answer the purpose. Details of a concrete dipping 
vat suitable for large flocks are given in Farmers’ Bulletin 481.
