Signed in 1840, the Treaty of Waitangi is an agreement between the British Crown and Maori. Around this time, there were 125,000 Maori and about 2000 settlers in New Zealand. Sealers and whalers were the first Europeans settlers, followed by missionaries.
Their male subjects burned 105 calories running, 52 walking; the women, 91 and 43. That is, running burns twice as many net calories per mile as walking. And since you can run two miles in the time it takes to walk one mile, running burns four times as many net calories per hour as walking.
When it comes to walking or running, people tend to burn between 80 and 100 calories per mile, no matter how fast or how slow they are. Half an hour of walking at a casual, walking-the-dog pace (2.5 mph, or a 24-minute mile) will burn about 97 calories. A brisk 4-mph stroll (15-minute miles), on the other hand, will burn about 161 calories in 30 minutes.
