These rains, and the close sultry weather accompanying them, too often bring on sickness in this passage. Every bad consequence, at least, is to be apprehended from them; and commanders of ships cannot be too much upon their guard, by purifying the air between decks with fires and smoke, and by obliging the people to dry their clothes at every opportunity. These precautions were constantly observed on board the Resolution[94] and Discovery; and we certainly profited by them, for we had now fewer sick than on either of my former voyages. We had, however, the mortification to find our ship exceedingly leaky in all her upper works. The hot and sultry weather we had just passed through, had opened her seams, which had been badly caulked at first, so wide, that they admitted the rain-water through as it fell. There was hardly a man that could lie dry in his bed; and the officers in the gun-room were all driven out of their cabins, by the water that came through the sides. The sails in the sail-room got wet; and before we had weather to dry them, many of them were much damaged, and a great expense of canvas and of time became necessary to make them in some degree serviceable. Having experienced the same defect in our sail-rooms on my late voyage, it had been represented to the yard-officers, who undertook to remove it. But it did not appear to me that any thing had been done to remedy the complaint. To repair these defects the caulkers were set to work, as soon as we got into fair settled weather, to caulk the decks and inside weather works of the ship; for I would not trust them over the sides while we were at sea. On the first of September[95] we crossed the equator, in the longitude of 27° 38ʹ W., with a fine gale at S. E. by S.; and notwithstanding my apprehensions of falling in with the coast of Brazil in stretching to the S. W., I kept the ship a full point from the wind. However, I found my fears were ill grounded; for on drawing near that coast, we met with the wind more and more easterly; so that, by the time we were in the latitude of 10° S., we could make a south-easterly course good.
