Transmission Changes. Greatest interest will be expect ed among the show vialtorn in the various types of transmission, for it is on this subject that engineers seem to be most at odds. Free wheeling, aynero-mush, constant mosh, herring-bone and the older type of sliding gear transmissions keep many an engineering meeting boiling hot and may be expected to add many a lay adherent and apponent to each typo
For the present, the free wheeling device introduced last summer, and to be soon on at icast! one ather manufacturer's products; at the show, is expected to gather the largest crowds. There seems to be some mystery surrounding this
appliance, although that will be enally dispelled with the knowledge that it is nothing else than a modern application of the coaster device we used to have on eur bicycles.

Gearing for High Speeds. Whatever tho type, however, we may confidently expect better und quieter trabamissions. Improved reads have brought about higher ong engincer average speeds, points out, which would greatly reduce the life of the
engine. To cope with this inrger engines must he built, which would prove more expensive to operate, or the trans- mission must be genred for high: speeds without raising the engine speed.
Despite all the talk about larger engines, however, it la the trans-! mission that is being looked upon by engineers for higher speeds. The engineers have succeeded in lowering the gear ratios, parti- cularly in second and third, while keeping them as quiet an ever.
Quiet operation, with the engine golne its fastest in second and high gears, has been achieved also by the use of internal gearing, particularly in four-speed trans- missions: Syncro-mesh, constant mesh and herring-bone tynes of gears attain the same objective:
