Doubling the Puerto de Pinas, the little vessel entered the river Biru, the misapplication of which name is supposed by some to have given rise to that of the empire of the Incas. *12 After sailing up this stream for a couple of leagues, Pizarro came to anchor, and disembarking his whole force except the sailors, proceeded at the head of it to explore the country. The land spread out into a vast swamp, where the heavy rains had settled in pools of stagnant water, and the muddy soil afforded no footing to the traveller. This dismal morass was fringed with woods, through whose thick and tangled undergrowth they found it difficult to penetrate; and emerging from them, they came out on a hilly country, so rough and rocky in its character, that their feet were cut to the bone, and the weary soldier, encumbered with his heavy mail or thick-padded doublet of cotton, found it difficult to drag one foot after the other. The heat at times was oppressive; and, fainting with toil and famished for want of food, they sank down on the earth from mere exhaustion. Such was the ominous commencement of the expedition to Peru. [Footnote 12: Zarate, Conq. del Peru, lib. 1. cap. 1. - Herrera, Hist. General, dec. 3, lib. 6, cap. 13.] Pizarro, however, did not lose heart. He endeavoured to revive the spirits of his men, and besought them not to be discouraged by difficulties which a brave heart would be sure to overcome, reminding them of the golden prize which awaited those who persevered. Yet it was obvious that nothing was to be gained by remaining longer in this desolate region. Returning to their vessel, therefore, it was suffered to drop down the river and proceed along its southern course on the great ocean. After coasting a few leagues, Pizarro anchored off a place not very inviting in its appearance, where he took in a supply of wood and water. Then, stretching more towards the open sea, he held on in the same direction towards the south. But in this he was baffled by a succession of heavy tempests, accompanied with such tremendous peals of thunder and floods of rain as are found only in the terrible storms of the tropics. The sea was lashed into fury, and, swelling into mountain billows, threatened every moment to overwhelm the crazy little bark, which opened at every seam. For ten days the unfortunate voyagers were tossed about by the pitiless elements, and it was only by incessant exertions - the exertions of despair - that they preserved the ship from foundering. To add to their calamities, their provisions began to fail, and they were short of water, of which they had been furnished only with a small number of casks; for Almagro had counted on their recruiting their scanty supplies, from time to time, from the shore. Their meat was wholly consumed, and they were reduced to the wretched allowance of two ears of Indian corn a day for each man.
