A PART from the unsuitability of the epithet, such an incident as is suggested by a recent Daily Mail poster, “Aëroplane Triumph; Expresses Collide; Passengers Injured,” may not occur for some years to come, but the rapid development of aeroplane locomotion within the last year indicates that it may be desirable, at no distant date, to formulate “rules of the road” for aëroplanes crossing each other's path at the same level, and, unless this is done fairly soon, there may be the same difficulty in obtaining international uniformity that has always existed in such other connections as those of language, coinage, and measurement of time.
