Commencing on the east, where the Greenland Sea washes the coast of
Labrador, and Hudson Strait leads to the intricate channels
communicating with the Arctic Ocean, we have on the first-named coast a
low and level region, which rises inland to a considerable elevation,
and then once more sinks on the shores of Hudson Bay. West of that bay
there is a wide extent of low country, intermixed with numerous lakes
and marshes; and then along the Arctic shore is a wild, barren, treeless
district, rising at length into the mountainous region of the Arctic
highlands. Amid them numerous rapid streams find their way into the
Arctic Ocean. Again they sink into the basin of the Mackenzie River,
which separates the in from the northern end of the Rocky Mountains.
Hence westward to the Pacific is a broad highland region, rising into
the lofty range of the Sea Alps.
