A JOURNEY IN BRAZIL. 



side, and might at first be easily confounded ; but a little 

 familiarity makes it easy to distinguish them. Where the 

 lateral moraine turns toward the front of the ancient glacier, 

 near the pohit at which the brook of Pacatuba cuts through 

 the former, and a little to the west of the brook, there are 

 colossal boulders leaning against the moraine, from the sum- 

 mit of which they have probably rolled down. Near the 

 cemetery the front moraine consists almost entirely of small 

 quartz pebbles ; there are, however, a few larger blocks 

 among them. The medial moraine extends nearly through 

 the centre of the village, while the left-hand , lateral moraine 

 lies outside of the village, at its eastern end, and is traversed 

 by the road leading to Ceara. It is not impossible that east- 

 wards a third tributary of the serra may have reached the 

 main glacier of Pacatuba. I may say, that in the whole 

 valley of Hasli there are no accumulations of morainic ma- 

 terials more characteristic than those I have found here, — 

 not even about the Kirchet ; neither are there any remains 

 of the kind more striking about the valleys of Mount Desert 

 in Maine, where the glacial phenomena are so remarkable, 

 nor in the valleys of Lough Fine, Lough Augh, and Lough 

 Long in Scotland, where the traces of ancient glaciers are 

 so distinct. In none of these localities are the glacial phe- 

 nomena more legible than in the Serra of Aratanha. I hope 

 that before long some members of the Alpine Club, thor- 

 oughly familiar with the glaciers of the Old World, not only 

 in their present, but also in their past condition, will come 

 to these mountains of Ceard and trace the outlines of their 

 former glaciers more extensively than it has been possible 

 for me to do in this short journey. It would be an easy ex- 

 cursion, since steamers from Liverpool and Bordeaux reach 

 Pernambuco in about ten days, arriving twice a month, while
