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.
Walking more quickly, however, will burn more calories in less time so you'll end up covering fewer miles. If you walk fast enough to cover a mile in about 12 minutes, you'll burn about as many calories as you would running, which averages out to about 16 calories per minute, Burfoot reports.
