Popocatepetl's crater

This crater is bell-shaped instead of conical. Many thousands of tons of sulphur have 

 been taken out of it and the supply seems inexhaustible. The sulphur is carried up 500 feet 

 by peons, who climb "chicken ladders." A windlass takes it the remainder of the distance 

 to the top. Here the peons put it on mats and slide to the lower edge of the snow-line with 

 it. The peak of this famous mountain is shown on page 641.
