Cook Islands 132
Captain Cook visited the
islands of Te-Au-O-Tu and Manuae in 1773 and named them the

The length of a minute of
latitude is always about 1 mile. A minute of a degree of longitude
varies from about 1 mile at the equator to 0 at the poles because the
meridians converge at the poles.
At 19°20' latitude, a minute of longitude would be
.946 miles. The scale at the bottom of the map shows that the
distance between 158°58' and 158°56'; two minutes of longitude is
equal to approximately 2 miles, which is correct.
The two parallels of latitude are 19°20'S and
19°21'S. At this latitude a minute of latitude is .99615 mile. But
according to the scale it would be 2 miles, twice the true
distance, which is not correct.
