I found a list of gifts Lewis and Clark gave the Indians but I need a list of things the Indians gave them in return.

I suggested you to check on www.wikipedia.org and type in Lewis and Clark in the search box.  You should be able to find your answer from there.

You might check the city or county of issue's Historical Society. They might like to have it displayed in a museum. They can give its approximate value, and you can donate it for tax deduction or simply let them "borrow" it for a designated period of time. And you can always try e-bay.

Go to the Texana section of the Central Library.  They are very helpful there, especially a man named Ira.  He will know how to find what you need.

I would check out www.ebay.com  or  www.amazon.com\n\nThat is a good place to look to find just about anything that you want.  \n\nIf that doesn't work, google what you are looking for.\n\nIf that also doesn't work, try your local antique shops.

Have you tried the "Native American Indian Resources" website? \n\n"Native American Myths" is another website with lots of links.\n\n"American Folklore" has a lot of information on Native American myths and legends.

they showed them how to trap and hunt for food and how to make clothing from the hides of animals that they killed, basically they taught them how to survive in the new America. with out the things they were used to in England, this new world was very harsh.  the Indians taught the settlers how to gather food like berries and nuts and showed them the plants that were good to eat. they taught them to make kayaks to navigate the rivers and streams.

Maybe some nice soap would be good, maybe socks?  Your idea sounds great, I'm just trying to add some other thoughts.  I think it so hard to know what they may need, but probably they could use many daily items.\n\nIt's wonderful that you are sending the presents. We, as the regular people of the US, need to reach out in friendship to Afghans and Iraqis.

try searching for them on ebay checking completed sales in advanced search. Unlike other methods, this will actually give you a sense of what you actually can get for them

Look at these links:\n\nhttp://www.cr.nps.gov/nhl/themes/Scanned%20Nominations/Lewis-Clark/LewisClark.htm\nhttp://visitmt.com/history/Montana_the_Magazine_of_Western_History/summer2003/montanatraveler.htm\nhttp://www.jeffcitymo.org/jeffcityweb.nsf/e0087b5460c4a721862569c2005fa85a/364a5eec4c9be37086256e5a005e9e00!OpenDocument\n\nThere's more than enough there for you to pick 4 that sound interesting and research a little about them.\n\nBTW, if you google search for landmarks instead of masses, I think you'll do better than you were
