“ The Napo River, formerly part of the boundary line between Colombia and Ecuador but now given over to Ecuador, has sources among the Ecuadorian volcanoes, Cotopaxi, Antisana, and others. At first the descent is rapid. At the foot of the Cordillera 100 miles from the source, and but 1500 feet above the sea, canoe navigation begins at the village of Napo. Sixty miles below, the Coca River comes in. This section includes the Napo missions, a beautiful region long known and visited by botanists and geologists. ”
