ARRANGEMENT.

The adverb clause may stand before the independent clause, between the parts of it, or after it.

+Direction+.---_Think, if you can, of another adverb clause to follow each independent clause in the preceding Lesson, and by means of a caret (^) indicate where this adverb clause may properly stand in the sentence. Note its force in its several positions, and attend to the punctuation. Some of these adverb clauses can stand only at the end_.
