m. Doubled to serve the purpose of brackets. It gives a medium between the light comma parenthesis and the heavy bracket parenthesis. It also has the advantage over brackets that when the parenthesis ends only with the sentence the second dash need not be given; this advantage, however, may involve ambiguity, as will be shown.
16. In every well regulated community—such as that of England,—the laws own no superior.–B. (The comma should either be omitted or placed after instead of before the second dash)
These are a dozen distinct uses of more or less value or importance, to which others might no doubt be added; but they will suffice both to show that the dash is a hard-worked symbol, and to base our remarks upon.
2. Debatable questions.
There are several questions that must be answered before we can use the dash with confidence. First, is the dash to supersede stops at the place where it is inserted, or to be added to them? Secondly, what is its relation to the stops in the part of the sentence (or group of sentences) that follows it? does its authority, that is, extend to the end of the sentence or group, or where does it cease? Thirdly, assuming that it is or can be combined with stops, what is the right order as between the two?
Beadnell's answer to the first question is: The dash does not dispense with the use of the ordinary points at the same time, when the grammatical construction of the sentence requires them. But inasmuch as a dash implies some sort of break, irregular pause, or change of intention, it seems quite needless to insert the stop that would have been used if it had not been decided that a stop was inadequate. The dash is a confession that the stop will not do; then let the stop go. The reader, who is the person to be considered, generally neither knows nor cares to know how the sentence might, with inferior effect, have been written; he only feels that the stop is otiose, and that his author had better have been off with the old love
