finance a project for the development of a rotary snow plough that was later to be widely employed in keeping Catitda's roads open to traffic throughout the winter. To-day, Mr. Sicard operates a factory covering 300;000 sq. ft. of floor space.

The normal type of snow plough creates high banks on each side of the road (Fig. I). Curves become " blind " and the snow is liable to fall or to be blown back into the road.

The Sicard rotary plough, on the other hand, sweeps the snow well clear of the highway and visibility is not impaired (Fig. 2).

A special attachment enables snow to be blown into an attendant lorry for removal—a valuable feature in clearing snow from towns (Fig. 3). It is said that a truck can be loaded in 20 seconds and that the force of the blower is such that twice the weight of snow can be packed into a vehicle, by comparison with other methods of loading. In residential districts, the snow is blown into neat piles on the front lawns of houses or into fields.

In ' rural areas, however, the snow may safely be swept on to the countryside, as shown in Fig. 4.

The plough gear comprises Iwo spirals, similar to the cutting mechanism of a mincing machine, mounted one aboNe the other, with a saw-toothed horizontal member between them. Thus, the hardest crushed snow can be cleared.
