In 1542 the settlement of Buenos Aires was re-established by an expedition sent for the purpose from Spain, under a tried adelantado, Cabeza de Vaca.
The settlement was at first called Aspinwall, in honour of William H.
The second settlement made by his expedition at Buenos Aires was even less successful and long-lived than the first.
Except on Charles Island, where settlement has existed longest, little or no influence of the presence of man is evident in the group; still, the running wild of dogs and cats, and, as regards the vegetation, especially goats, must in a comparatively short period greatly modify the biological conditions of the islands.
That a far more advanced race had at one time a settlement on the north-west coast is indicated by the cave-paintings and sculptures discovered by Sir George Grey.
