Where the names of streets are placed against buildings the letters which compose the name should not be less than 4 inches in height by 2 inches in breadth, with a space between each letter of not less than 1 inch; a light colour should always where practicable be used for the back ground, and black or blue for the letters. One great objection to painted letters is that they must be frequently repainted, and in order to do this, ladders have to be raised against the building, which the occupiers naturally object to without previous notice: it is always very annoying to any citizen to have the head of a painter appearing outside his bed-room window at any time, and more especially at an inconvenient hour in the morning. In selecting names for streets it is very important that they should not be duplicated in a town, and also that there should be some sense in their nomenclature; generally some local association can be found with a family or historical name which is suitable for the street. Nothing is more ridiculous than to see such names as Bath Street or York Road given to streets which have as much association with such places as with Jericho. The street having been properly and conspicuously named, the next point to consider is that of the manner in which it shall be numbered, there being three methods in vogue by which this can be effected. (1.) By allotting even numbers on one side of the street and odd numbers on the other side. (2.) By allotting consecutive numbers up one side of the street, and down the other side. (3.) By allotting corresponding numbers to both sides of the street, which are distinguished by a prefix of north and south, or east and west, as the case may require. The first is by far the best method to pursue, for the following reasons: If the street is ever extended after being numbered, the sequence is in no way disturbed. By this method any house can be more easily found, as on reference to a directory it will at once be seen at which end of the street it is situated. If the second method had been adopted this would be impossible, except for the first few numbers, and where a street is of considerable length with branch streets running into it this is of the greatest importance. It is the best method also for the Post-Office officials, as it facilitates the district sorting of the letters. Giving each side of the street distinctive prefixes to its name, such as north and south, &c., is evidently a bad plan, and leads to much confusion. In allotting numbers to premises in a street, if it has been already numbered care should be taken to disturb existing numbers as little as possible, for an altered number involves considerable expense as well as inconvenience to the occupier of business or trade premises, owing to the necessity of altering bill heads, letter paper, &c., and sometimes even considerable trouble and expense in order to secure the validity of the title.
