Thus ended the maritime enterprises of Cortés, sufficiently disastrous in a pecuniary view, since they cost him three hundred thousand _castellanos_ of gold, without the return of a ducat.[277] He was even obliged to borrow money, and to pawn his wife’s jewels, to procure funds for the last enterprise;[278] thus incurring a debt which, increased by the great charges of his princely establishment, hung about him during the remainder of his life. But, though disastrous in an economical view, his generous efforts added important contributions to science. In the course of these expeditions, and those undertaken by Cortés previous to his visit to Spain, the Pacific had been coasted from the Bay of Panamá to the Rio Colorado. The great peninsula of California had been circumnavigated as far as to the isle of Cedros, or Cerros, into which the name has since been corrupted. This vast tract, which had been supposed to be an archipelago of islands, was now discovered to be a part of the continent; and its general outline, as appears from the maps of the time, was nearly as well understood as at the present day.[279] Lastly, the navigator had explored the recesses of the Californian Gulf, or _Sea of Cortés_, as, in honor of the great discoverer, it is with more propriety named by the Spaniards; and he had ascertained that, instead of the outlet before supposed to exist towards the north, this unknown ocean was locked up within the arms of the mighty continent. These were results that might have made the glory and satisfied the ambition of a common man; but they are lost in the brilliant renown of the former achievements of Cortés.
