The Bicycle Nuisance.— We have received several complaints of the reckless manner in which bicycles are ridden through the streets of Canterbury, especially of an evening, when there is as a rule great deal of traffic in the town. Many bicyclists never trouble themselves to ring their bell, so as to give warning of their approach, and it is dangerous for old and inflrm persons to cross the road, as they run the risk of being knocked down. The attention of tbe police should be directed to this matter.
