The general was induced by these circumstances to despatch two vessels, under Francisco de Montejo, with the experienced Alaminos for his pilot, to explore the coast in a northerly direction, and see if a safer port and more commodious quarters for the army could not be found there. After the lapse of ten days the Mexican envoys returned. They entered the Spanish quarters with the same formality as on the former visit, bearing with them an additional present of rich stuffs and metallic ornaments, which, though inferior in value to those before brought, were estimated at three thousand ounces of gold. Besides these, there were four precious stones, of a considerable size, resembling emeralds, called by the natives _chalchuites_, each of which, as they assured the Spaniards, was worth more than a load of gold, and was designed as a mark of particular respect for the Spanish monarch.[21] Unfortunately, they were not worth as many loads of earth in Europe. Montezuma’s answer was in substance the same as before. It contained a positive prohibition for the strangers to advance nearer to the capital, and expressed his confidence that, now they had obtained what they had most desired, they would return to their own country without unnecessary delay. Cortés received this unpalatable response courteously, though somewhat coldly, and, turning to his officers, exclaimed, “This is a rich and powerful prince indeed; yet it shall go hard but we will one day pay him a visit in his capital!”
