Hello. You did not underline any clause in the sentence above, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
If the underlined clause is "tis going" it means that the speaker of the sentence is indicating that the clock is working.
If the underlined clause is "it strikes well and hearty" it means that the watch is working very well, vigorously and correctly. This is because the words used give the feeling of something that is healthy and that has vigor and disposition for any activity.
The chapter in The Iroquois Book of Rites contains information about the rules and regulations about of the Iroquois Nation can be found in chapter 6, 'The laws of the league'. When you are reading the book take notes and highlight any important information so that when you go to answer questions you can make references to the highlighted material.
Hope this helps if you have any other questions or would like further explanation just let me know! :)
The answer is A. to the lake
