The commission given to Aguado was very brief, and so vaguely worded that it might mean much or little, according to the discretion of the commissioner and the necessities of the case as viewed by him. "We send to you Juan Aguada, our Groom of the Chambers, who will speak to you on our part. We command you to give him faith and credit." A letter was also sent to Columbus in which he was instructed to reduce the number of people dependent on the colony to five hundred instead of a thousand; and the control of the mines was entrusted to one Pablo Belvis, who was sent out as chief metallurgist. As for the slaves that Columbus had sent home, Isabella forbade their sale until inquiry could be made into the condition of their capture, and the fine moral point involved was entrusted to the ecclesiastical authorities for examination and solution. Poor Christopher, knowing as he did that five hundred heretics were being burned every year by the Grand Inquisitor, had not expected this hair-splitting over the fate of heathens who had rebelled against Spanish authority; and it caused him some distress when he heard of it. The theologians, however, proved equal to the occasion, and the slaves were duly sold in Seville market. Aguado sailed from Cadiz at the end of August 1495, and reached Espanola in October. James Columbus (who does not as yet seem to be in very great demand anywhere, and who doubtless conceals behind his grave visage much honest amazement at the amount of life that he is seeing) returned with him. Aguado, on arriving at Isabella, found that Columbus was absent establishing forts in the interior of the island, Bartholomew being left in charge at Isabella.
