Segment 1 The narrator explains that sheep are regularly attacked by parasites of the skin and fleece, causing injury and death, as well as impaired growth and quality of wool. Research is taking place to destroy external parasites and protect the animals and to control diseases caused by parasites. A brief history of sheep dipping is given. It became general practice after 1843, when William Cooper invested an arsenic sulphur powder dip for sheep to combat parasites. Examples of parasites are displayed, including maggot flies, sheep keds, lice, ticks, itch mites and scab mites. A typical bath for dipping sheep in pesticide is seen. Farmers with small herds can use a metal drum sunk into the ground to individually dip animals. A circular bath commonly used in East Africa is shown. Long baths used for large flocks in places such as Australia and South America are seen. The technique of spraying, rather than dipping, sheep is demonstrated.

Segment 2 The technique of showering sheep in pesticide is shown. The laboratories of the Cooper Technical Bureau are shown, where research is taking place into control of animal parasites. The various types of sheep dip are seen, including arsenic sulphur, carbolic, DDT and organo-phosphate compounds. The steps of making up a sheep bath are demonstrated, from mixing the wash to aftercare of the animals. Time start: 00:09:04:09 Time end: 00:17:58:24 Length: 00:08:54:15
