The expedition set sail for the south in August 1486. Passing the spot where Diego Cam had erected his farthest pillar, Diaz reached a headland, now known as Diaz Point, where he, too, placed a Portuguese pillar that remained unbroken till about a hundred years ago. Still to the south he sailed, struggling with wind and weather, to Cape Voltas, close to the mouth of the Orange River. Then for another fortnight the little ships were driven before the wind, south and ever south, with half-reefed sails and no land in sight. Long days and longer nights passed to find them still drifting in an unknown sea, knowing not what an hour might bring forth. At last the great wind ceased to blow and it became icy cold. They had sailed to the south of South Africa. Steering north, Diaz now fell in with land--land with cattle near the shore and cowherds tending them, but the black cowherds were so alarmed at the sight of the Portuguese that they fled away inland. We know now, what neither Diaz nor his crew even suspected, that he had actually rounded, without seeing, the Cape of Good Hope. The coast now turned eastward till a small island was reached in a bay we now call Algoa Bay. Here Bartholomew Diaz set up another pillar with its cross and inscription, naming the rock Santa Cruz. This was the first land beyond the Cape ever trodden by European feet. Unfortunately the natives--Kafirs--threw stones at them, and it was impossible to make friends and to land. The crews, too, began to complain. They were worn out with continual work, weary for fresh food, terrified at the heavy seas that broke on these southern shores. With one voice they protested against proceeding any farther. But the explorer could not bear to turn back; he must sail onwards now, just three days more, and then if they found nothing he would turn back. They sailed on and came to the mouth of a large river--the Great Fish River. Again the keen explorer would sail on and add to his already momentous discoveries. But the crews again began their complaints and, deeply disappointed, Diaz had to turn. "When he reached the little island of Santa Cruz and bade farewell to the cross which he had there erected, it was with grief as intense as if he were leaving his child in the wilderness with no hope of ever seeing him again." To him it seemed as though he had endured all his hardships in vain. He knew not what he had really accomplished as yet. But his eyes were soon to be opened. Sailing westward, Diaz at last came in sight of "that remarkable Cape which had been hidden from the eyes of man for so many centuries." [Illustration: THE WEST COAST OF AFRICA.
