east to Labrador to linger and feast on the prolific berry 
crops of the autumn in that land in order to build up for 
their long ocean journey of 4,000 miles to the north east 
portion of the South American Continent. Before start- 
ing, they move off in mass to Nova Scotia, and late in the 
northern season undertake that tremendous journey to 
Brazil. Then, by easy stages, to the southern summer in 
the Argentine. On their return journey, the route is 
varied as they proceed north in the Andes region thence 
along the land bridge through Panama and Mpxico. 
though some of them here go straight north from Yuca- 
tan across the ■western end of the Gulf of Mexico, and 
both lots then uniting for a leisurely journey up the West- 
ern States to Canada, delaying their pace if necessary to 
keep behind the wintry conditions moving ahead of them 
to the north. Our golden rdover does the same tremendous 
journey from Australia to Siberia, but escapes the long 
and arduous ocean flight by the use of the land bridges 
occuring on this route. Although here again there are var- 
iations, for some of these birds have been found in the 
Midway Islands and the Hawaiian-Samoan Groups and 
as far east as the Low Archipelago. To reach these points 
long and hazardous sea journeys equal in extent to those 
of their American cousins have had to be undertaken. 
How these birds can navigate to these small landings in 
the vast Pacific Ocean can only be wondered at. it can- 
not be calculated. One therefore leaves the subject of 
bird migration in a defeated mood, realising that all we 
know of it as yet, merely leaves us on the fringe of know- 
ledge of the subject and the impression that we will never 
know all that there is to be learned about it.
