soda, to the extent of 2 lbs. to every тоо gallons 
of water, should be added. 
For mixing the dip, a number of empty oil drums 
with wire handles are required. First bump the 
packets on the floor to loosen the contents, then cut 
them open and pour the powder into an empty , 
petrol or kerosene tin. Then get a pannikin of pint 
size, take four pannikins full of dry powder from the 
petrol tin, and put it into the oil drums, four panni- 
kins to each drum. Then pour on a little water, and 
carefully mix into a paste, stir thoroughly, and add 
water little by little till the drum is filled, stirring all 
the time. It is advisable to do this mixing the day 
before the dip is required. During jetting, if re- 
plenishment is likely, see that the dip is soaked as 
long as possible before being used. 
If each drum is mixed in this way, it will contain 
four pannikins (four pints) of dip to 5 gallons of 
water. When it becomes necessary to replenish the 
vat, all that is required is to empty a drum of the dip 
into the vat, and refill the drum from the clean 
water tank, and pour it also into the vat: This 
gives the required strength, i.e, 4 pints of powder 
dip to то gallons of water. 
When the vat is charged, and the engine started, 
the nozzles should be opened to let out what water 
there is in pump, pipes, and hoses. Once the yellow 
liquid appears, the nozzles should be shut off until 
the release valve opens on the pump. This indicates 
that the required pressure is obtained, and jetting 
can be commenced, 
FOR PREVENTING FLY TROUBLE 
Before putting the sheep into the race, all badly- 
blown sheep should be picked out and penned for 
special treatment. Unblown sheep and sheep only 
slightly affected should then be put into the race. 
Do not crutch before jetting. Jet all ewes, lambs, 
weaners or rams in the crutch, over the tail, inside 
the hind legs, and on the heads and necks if necessary
