The tenth annual motor exhibition was opened at the Waverley Market, Edinburgh, on the t5th inst. Both Ensfish and Scottish manufactUrers are well represented, and numerous commercial vehicles are staged. The present exhibition demonstrates the fact that motors, both of the light and heavy types, are proving themselves indispensable in their particular spheres of usefulness. The rival claims of chain and cardan drive still receive a considerable amount of attention, and the exhibits showing these two forms uf final transmission are practically equal in number.
