Embarking, soon a large opening in the coast was discovered, and entered by Grijalva, the chaplain says, the last day of May. Puerto Deseado[24] the commander called his anchorage, being the desired spot in which might be repaired the leaky ships. The Spaniards thought themselves at first at the mouth of a river, but on further examination, it appeared to them more like a sea. Whereupon the pilot Alaminos, who, notwithstanding evidence to the contrary, notwithstanding three days’ explorings, left this salt-sheet still landlocked, never ceased insisting that Yucatan was an island, and he now gravely assured his commander that the great opening opposite Amatique Bay and Golfo Dulce, or if that were too far, then opposite Chetumal or Ascension, confirmed his suppositions, and settled the matter in his mind that this was the termination of the islands; hence the names Boca de Términos, and Laguna de Términos,[25] which followed. The temples here seen were supposed by the Spaniards to be places where merchants and hunters made their sacrifices. A greyhound, eager in the pursuit of game, neglected to return in time and was left behind; when the Spaniards came with Cortés they found the animal well-fed and happy, but excessively glad to see them. Before departing, Grijalva again declared for Spain, “as if,” growls Las Casas, “the thousand possessions already taken were not enough.” Indeed, this fierce charging on a continent, so often repeated, hurling upon the inhabitants a new religion and a new king, was about as effective as Caligula’s advance on Britain, when, preparatory to crossing, he drew up his troops in battle array, on the seaboard, and gave orders to collect shells, the spoils of conquered ocean. Proceeding the 8th of June, and creeping stealthily along the coast,[26] dropping anchor at night and weighing it with the dawn, they came to a river which they called San Pedro y San Pablo, and then to a larger one, the native name of which was Tabasco,[27] after the cacique of the city, but which the Spaniards called Grijalva, in honor of their commander. The face of nature here changed. The low, gray hills of the peninsula gave place to elevations of enlivening green, made lustrous by large and frequent streams. Boldly in the front stood the heights at present known as San Gabriel; beyond continued the flat, monotonous foreground of a gorgeous picture, as yet but dimly visible save in the ardent imaginings of the discoverers.
