When a quotation ends a sentence the quotation marks are placed after the period.
The comma is always placed inside the quotation marks.
The position of the other marks (semicolon, colon, exclamation, and interrogation) is determined by the sense.

If they form a part of the matter quoted, they go inside the quote marks; if not, they go outside them.

When quotation marks occur at the beginning of a line of poetry, they should go back into the indention space.
"Breathes there a man with soul so dead Who never to himself hath said, 'This is my own, my native land' ?" This illustration is also a good example of the use of marks in combinations.

We have first the single quotation marking the end of the included quotation, then the interrogation which ends the sentence, then the double quotation marks in their proper position.
Quotation marks should not be used needlessly.

Very familiar expressions from the best known authors, such as _to the manor born_, _a conscience void of offence_, _with malice toward none and charity for all_, have become part of the current coin of speech and need not be quoted.
