BRASS RULES.

Rules are required mainly for table-work, and for pages which contain two

or more columns. They are also useful in titles and jobs. Brass rules

should never be more than type height, unless for perforating purposes,

to divide railroad checks, &c. A shade lower would be often better, as

the pressman would be enabled to bring off their impression more clearly.

In table-work, the rule and figures should be separated by a lead, and

all the rules should fit closely and accurately.
