measured areas could be cut, weighed and compared with 

 other treatments or other forage. 



Many other factors will enter into such a demonstration 

 also. The field chosen for the demonstration should be 

 fairly representative of the conditions on the majority of 

 the farms in the community. The farm operator must be 

 in good standing and he should be influential in his own 

 neighborhood. Other factors, such as seed, rainfall, nat- 

 ural fertility, etc., should be known, taken into considera- 

 tion and explained. Further, in order to get the most 

 possible out of the demonstration meeting, careful prepara- 

 tion should have been made for it by notices in the local 

 papers, and by carefully choosing and advertising the 

 time. Credit should be given the cooperator who did the 

 work, and usually he should himself explain how the 

 good crop was grown. Still other factors are important.

 to convince, to have the persons present actually take part 

 in the demonstration, doing the thing being taught when- 

 ever possible and on the spot. Such lines of work as 

 poultry selection or flock culling, where those present can 

 handle the birds and feel and see the points brought out 

 by the demonstrator, pruning fruit trees where each may 

 try his hand and give his reasons for what he does, are 

 peculiarly effective. In home demonstrations, such as 

 cooking, canning and sewing, this method is particularly 

 applicable, because one can actually learn to do by doing 

 and may clearly see the relation of the principle to the 

 practice. 



MARKETING DEMONSTRATIONS 



The demonstration method may be applied to problems 

 of marketing when the solution is known, as well as to 

 questions of production. But it is much more difficult to
