+Direction+.—Correct the following errors, and give your reasons:—
1. That custom has been formerly quite popular. 2. Neither will they be persuaded, though one rose from the dead. 3. He that was dead sat up and began to speak. 4. A man bought a horse for one hundred dollars; and, after keeping it three months, at an expense of ten dollars a month, he sells it for two hundred dollars. What per cent does he gain? 5. I should say that it was an hour's ride. 6. If I had have seen him, I should have known him. 7. I wish I was in Dixie. 8. We should be obliged if you will favor us with a song. 9. I intended to have called.
+Explanation+.—This is incorrect; it should be, I intended to call. The act of calling was not completed at the time indicated by intended.
+Remark+.—Verbs of commanding, desiring, expecting, hoping, intending, permitting, etc. are followed by verbs denoting present or future time. [Footnote: The "Standard Dictionary" makes this restriction: "The doubling of the past tenses in connection with the use of have with a past participle is proper and necessary when the completion of the future act was intended before the occurrence of something else mentioned or thought of. Attention to this qualification, which has been overlooked in the criticism of tense-formation and connection, is especially important and imperative. If one says, 'I meant to have visited Paris and to have returned to London before my father arrived from America,' the past [present perfect] infinitive … is necessary for the expression of the completion of the acts purposed. 'I meant to visit Paris and to return to London before my father arrived from America,' may convey suggestively the thought intended, but does not express it.">[
The present infinitive expresses an action as present or future, and the present perfect expresses it as completed, at the time indicated by the principal verb. I am glad to have met you is correct, because the meeting took place before the time of being glad.
I ought to have gone is exceptional. Ought has no past tense form, and so the present perfect infinitive is used to make the expression refer to past time.
10. We hoped to have seen you often. 11. I should not have let you eaten it. 12. I should have liked to have seen it. 13. He would not have dared done that. 14. You ought to have helped me to have done it. 15. We expected that he would have arrived last night. 16. The experiment proved that air had weight.
+Remark+.—What is true or false at all times is generally expressed in the present tense, whatever tense precedes.
There seems to be danger of applying this rule too rigidly. When a speaker does not wish to vouch for the truth of the general proposition, he may use the past tense, giving it the form of an indirect quotation; as, He said that iron was the most valuable of metals. The tense of the dependent verb is sometimes attracted into that of the principal verb; as, I knew where the place was.
17. I had never known before how short life really was. 18. We then fell into a discussion whether there is any beauty independent of utility. The General maintained that there was not; Dr. Johnson maintained that there was. 19. I have already told you that I was a gentleman. 20. Our fathers held that all men were created equal.
