A writer on automobilism and roads cannot leave the latter subject
without a reference to some of the obstructions and inconveniences to
which the automobilist has to submit. If the automobilist proved
himself a "road obstruction" like any of the following he would soon

A correspondent in the _Auto_, the chief Parisian daily devoted to

2. Drivers who would not make way to allow one to pass - 86

3. Driver is asleep - 8

4. Drivers not holding the reins - 12

5. Drivers in carriages, or carts, without lights at night - 81

6. Drivers stopping their horses in the middle of the road or at

8. Dogs throwing themselves in front of one - 35

9. Flocks of sheep met without guardians near by - 8

10. Cattle straying unattended - 10

11. Geese, hens and children in the middle of the road - 30
