Alison, Have you been to your local library? I suspect you'll find a book there that will answer every one of your questions - but your classmates may have checked out the book by now. Have you looked on the county website? You might very well find the answers there, as well - though I have not checked the website out for you. I taught seventh grade for over 30 years, and I know that a bright seventh grader - which you appear to be - can do this kind of research very nicely, and I suspect your teacher intended for you to do some work in the library, or else to find the websites that have this kind of information. It would be defeating the purpose of your assignment if someone here were to do the research for you and send it to you in a single message, now wouldn't it? And by direct email, so you needn't even check out the list again? Oh, dear! Good luck with your report. I'm sure you'll do it well. Do try the county's website. I think you'll find what you need there. ....BettyC
