6 the end may be reached with too much space for the last measure, but not enough for an- other one. Carrying a measure from the end of one score to the beginning of the next is not practised now, as it once was.

Bar-lines are usually drawn through each stave of vocal music separately, and in instrumental music through as many staves as belong to the same instrument or group of instruments, e.g., through the two staves of a piano part, and the four or five belonging to the "strings" in a full score. . These instrumental staves are also usually connected by a brace at the left-hand edge of each score thus:

{{center|{{xxxx-larger block| { {{gap}}{{font-size|30%|or}}{{gap}}[}} {{fs|90%|Fig. 1.}}}}

Uniform bar-lines may be ruled a page at a time, if care be taken not to make the line continuous through more than the required number of staves. It is a fault which one commits the moment watchfulness is relaxed, and entails much scratching out. Where the measures vary in length the ruling will most readily be done in light pencil with a T square, and afterwards inked. A single bar-line out of the perpendicular will spoil the appearance of a whole page.
