Tur ZonE or PosTGnACIAL EMERGENCE IN NORTHEASTERN LABRADOR 
AND IN NEWFOUNDLAND. 
The path of the “ Brave” was such as always to keep us in view of 
memorials of recent uplift of the land. These were found to be so 
numerous and so striking that one’s note-books rapidly filled with the 
data of their nature and occurrence. If all other sources of geological 
interest failed on the coast, the singularly fresh records of emergence 
are yet sufficient to refute Lieber’s statement that “the geology of 
Labrador is of extraordinarily little interest.” The account of the 
cruise would be incomplete without reference being made to the obser- 
vations made in connection with this subject. 
Packard’s summary in “The Labrador Coast” makes it unnecessary 
to review the earlier studies. Still more recently, Low has published 
the elevations of raised beaches in Ungava Bay, Hudson’s Bay, James 
Bay, and in the interior of the peninsula. So far as known, all the 
beaches described by both authors are of postglacial date and are 
related to the elevated shore-lines early described in the Gulf of St. 
Lawrence. On account, however, of the scant information we possess 
concerning the actual heights of the Atlantic coast beaches, no very 
definite correlation of these with one another or with the beaches 
farther west has yet been made. Thus an accurate idea of the amount 
or kind of elevatory movement that the Labrador peninsula has suf- 
fered in postglacial time, is yet lacking. What light last summer’s 
coastal studies throw on the question will first engage our attention. 
The barometric method was used in fixing elevations. Four standard 
compensated aneroids were employed. The accessibility of the sea- 
level and of the British Admiralty’s triangulation stations as check- 
points, of course, give the aneroid an exceptionally large share of 
advantage as compared with that enjoyed by the same instrument 
working inland. It is believed that the error seldom exceeded five 
feet. At any rate, the accuracy obtained was sufficient for the main 
purposes of the study. 
It was found to be impossible to group the beaches with reference 
to distinct levels, the deformation of which would indicate the type or 
types of crustal movement in postglacial time. At only one anchorage 
was there discovered a correspondence among the different beaches 
which showed that there were special beach-building periods in the 
whole time since uplift began. This was at Kirpon Harbor near Cape
