165 x 117 mm. Showing a student at an agricultural college spreading fertiliser from the back of a bullock drawn metal cart. The caption on the reverse reads '(See Feature Set Intro. No.456). (21). Fertiliser is new too. Spread superphosphate on the college land is something everyone has to learn. Before the end of the course every student will have seen with his own eyes the benefits which result. Then it will be his job to tell the farmers in the area'.
