Conducting a 50gms is the equivalent of 2 Treetop-squash-bottle tops. But you can use a matchbox if you like--or a teaspoon. Funny isn't it, how Demonstration some people know exactly how much a measure is? I remember my mother when she was cooking, could just pick up a handful of salt or sugar. She never used a measure of any kind. But she never seemed to make a mistake-we certainly all enjoyed her cooking! Oh yes, where were we? Treetop tops. And make sure you don't use them for anything else after using them for dusting...." The obvious risk here is that the farmers will be distracted from remembering the all-important recommended dosage. Keep it silent. Sometimes watching and listening at.the same time is not easy. Better to first say what you are going to do, and then stay silent while you are giving the actual demonstration. There will be times, of course, when you need to explain while doing; but keep the two separated as much as possible. Keep it slow. In explaining what you are going to do, telling the farmers what to watch out for and then demonstrating the skill, move at a slow enough pace to allow for a more complete understanding than ifyou hurry through the processes. Make sure everyone can see. Sometimes the processes you are demonstrating are very small scale-like operating a moisture metre or identifying the black spot on a mature maize cob.

And make sure that your body or your hands are not masking important parts of the equipment or exhibit. Demonstrate from the operator's point of view. When you are demonstrating, position the farmers so that they are behind you if you are showing a complicated process. Then they will see everything from the point of view they will have when perform- Chapter 8
