by the current that always sets around the great southern promon- 
tory, and the south-easterly winds help this.” 
From what little is known about the currents concerned in 
transferring these icebergs, one would expect that such groups as 
those of 1892 and 1893 under Patagonia would, when they began 
to go eastward, separate and draw into lines as we find them in 
1894 and 1895, because the current is more rapid from latitude 
30° southwards, and therefore the most southerly icebergs would 
travel fastest and also have fewer miles in a degree; and we 
cannot overlook the effect of the wind, which would necessarily 
be greater on icebergs presenting large flat surfaces than on those 
presenting sloping sides. Simply as evidence on this point, it is 
to be hoped that the ‘“‘ Dumbartonshire ” will be sighted again. 
Although the evidence of easterly drift appears to me to be 80 
strong, I do not mean to assert that all the icebergs seen recently 
between the Cape and Australia came from the icefields under 
the lee of Patagonia. The experience of the master of the 
“Ladas” barque, bound from South America to Australia, shews 
that in latitude 50° to 53° he passed enormous fields of ice, and 
after passing the prime meridian they became so thick that he 
had to'work northwards to avoid them, and it is more than 
probable that some of these made northing and joined the others 
drifting eastward. 
Reference has already been made to the unusual position of 
icebergs between latitudes 40° and 50°. - Maury, as we have seeD, 
made the easterly limit 55°, Towson made it 10° east; the reports — 
now under discussion make it 110° east. 
Similar, but not so great uncertainty as to the extent of ice seems 
to attach to the area between New Zealand and Cape Horm — 
Admiral Fitzroy! says :—“ In the South Pacific, between 150° and 
100° west longitude, and 50° to 60° latitude, every shi 
risks a passage through it finds numerous and some enormous 
masses of ice. Immense islands rather than icebergs have bee?
