A good compositor will be careful to make the lines overlap each other, brick-wise, and not allow a joint to fall directly under another. Masters who aim to do cheap rather than good work have the music lines cast double or triple, to expedite composition. Such work has a very slovenly look, as the joints of the lines, coming under one another, are apparent in the entire depth of the staff. We have seen books set in this manner, in which all the lines seem to be composed of dotted rule, instead of a continuous stroke.

The compositor should be careful to make the stems of all the notes in a page of the same length, except those of grace-notes, which should be about half as long.

PLAN OF CASES.

The following plan of cases was arranged by the music typographer, J. M. Armstrong of Philadelphia, expressly for the founts of music cast by The MacKellar, Smiths & Jordan Co., specimens of which are shown on [page 114]. A table of comparative bodies is given on [page 115].
