     We spent the next three days based in Paihia, in the famous

Bay of Islands.  Although Paihia is only a town,  it is a good base

for exploring the northern part of the Northland.  We spent one day

in nearby Waitangi,  visiting the site (地点) of the first European

settlements and signing of the Treaty of Waitangi, which created

New Zealand as it is today.

      On the site, there is a fantastic museum which explains the

history of the country, as well as the relationship between the

European settlers and the native Maori tribes. There is also an

excellent example of a Maori waka, or carved canoe, in which the

original Maori tribes arrived in Aotearoa, or the Land of the Long

White Cloud.

      It was a great introduction to New Zealand history and culture

and would give us a good basis for understanding the Maori culture

that we would meet with as we traveled through the country.

    The weather wasn't fit to sailing through the blue, island-

dotted bay, so the next day we headed across the point to the

Kauri Coast and the Waipoa Kauri Forest to see the high Kauri

trees, one of the few places in the country where these big trees

that once covered the island still exist. Standing hundreds of feet

high, with girths that would take 20 men to circle, these

prehistoric(史前的) trees were used for everything from wakas to

homes. Most were cut down, and only a few still survive. The

trees in the forest are over 1 000 years old, and walking along the

paths deep into the bush to see them was like walking through land

where dinosaurs once walked.

      On the way back, we stopped in several small villages and

towns, each of which seemed more Shire-like. We had almost

forgotten that this was Lord of The Rings land, but in the rolling

green hills of the central northland, we remembered that Bilbo

Baggins and company could have lived here, too.
