Excellent description & instructions. Was reading a Western themed book, that was about a sheepherder in Wyoming in 1872 & he was buying sheep dip. So, had to look it up. His only choice to buy was Semple's Scotch Sheep dip: strong leaf tobacco & vegetable extracts @ 75 cents/gallon In its concentrated form. Glad the scientists have veers away from dips with DDT. Was very educational to see the parasites & other insects in their growing stages. Loved the music!
