464 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 point 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
