These fancies appear to have been shared by his companions, among whom were several accomplished navigators and geographers. The delusions were of course largely due to the erroneous estimate of the size of the globe, which made its circumference too little by some thousands of miles. But his companions could not be persuaded to approve his scheme of going on to circumnavigate the globe. The glamor of that vision did not blind their eyes to the worn and dilapidated condition of the ships, the lack of supplies, and the weariness of the crews. They were in no condition, they insisted, to proceed further through unknown regions. It was already satisfactorily demonstrated, they held, that they had reached the Asian coast. The part of prudence was to turn back to Isabella, if not to Spain, and refit their vessels for another and longer voyage. These counsels finally prevailed upon Columbus himself, at the time when his flotilla lay at anchor in the Bay of Cortez, near the western extremity of Cuba. He was indeed so near that extremity that a day or two more of sailing would have brought him to Cape San Antonio and would have shown him that Cuba was an island. Or from the top of some tall tree, or even from the mast head, he might have looked across the lakes and lowlands of that region and seen the waters of Guadiana Bay, on the north side of the island. But this was not to be. Instead, he required every member of his company, from sailing master to cabin boy, to swear to and sign a formal declaration to the effect that the land which they had discovered and explored was a part of the Indies and of the Asian continent. Then, on June 13, he turned his course toward the southeast, only to enter another archipelago, the San Felipe and Indian keys. Beyond lay a large land, with mountains, to which he gave the name of Evangelista. It was, of course, the Isle of Pines, which he reached a little south of Point Barcos. Taking in a supply of water and wood, he skirted the coast southward, with the result that he ran into the land-locked recesses of the Bay of Sunianea. Finding no thoroughfare in that direction, he sailed back almost to the Bay of Cortez, and then made his way along the Cuban coast, through the archipelagoes, milky seas and what not which had given him so much trouble on his westward trip.
