All of Cagayan has been as quiet as Manila for many days and months. Tributes are being collected from the encomiendas that remained to be pacified and subdued. A memorandum of encomiendas and villages explored lately, with an account of the discovery of Tuy, accompanies this letter.
I enclose, with the duplicate, also the relation of the late exploration of Tuy, in which I stated that my son Don Luis would remain there, in order to make another entrance of not less importance, of which I had a reliable report and account. It happened that, having gone upon this errand, and having arrived with the soldiers that he was taking to the province of Ylocos, through which he had to pass, he was taken ill, in the month of October, with attacks of fever. This sickness was very severe, and he came here to be treated; and, although he is doing well, he has not entirely recovered his strength. Almost all the soldiers fell sick at the same time, as that district is at that season very unhealthful. Captain Don Alonso de Sotomayor died, as well as some of the soldiers there. Others were brought to the city sick, and so the expedition had to be abandoned until a more favorable opportunity.
