On his arrival at court he advocated his system of peaceful conquest with his usual vigor, but his action gave great offence to the cabildo of Guatemala. Two indignant letters were addressed to the emperor attributing to him the existing troubles and turmoils.[XX‑46] The direct cause of these despatches was the receipt of two decrees obtained by the representations of Las Casas, the first of which was addressed to the bishop and governor of Guatemala and intended to remedy the prevailing neglect in the religious instruction of the Indians and negroes. It ordered that at a stated hour each day, all such as were not already instructed should be taught their religious duties.[XX‑47] The second guaranteed to Las Casas and his companions, in their labors in Tuzulutlan, freedom from interference on the part of the Spaniards.[XX‑48] At the same time he obtained other documents authorizing him or his companions to take such Spaniards as they themselves might select into the converted regions. Letters of thanks, also, were sent to such caciques as had aided in the work begun, and lastly as a precaution against the interference of Alvarado, the assistance of certain caciques was secured to the Dominicans, and the adelantado and his lieutenant commanded not to interfere with them.[XX‑49] But Las Casas was aware that the promulgation and execution of a decree in the western world were two different matters. He had learned by experience that subterfuge was commonly resorted to in order to prevent the enforcement of a cédula or delay its operation until there was no longer necessity for it, and this without the charge of disloyalty being incurred. The ceremony of kissing the royal order and placing it upon the head was duly and submissively performed, but if it could be alleged that his Majesty had been misinformed, ground for appeal was at once established, and its execution postponed until a truthful statement of the question could be submitted to the king. This delayed the arrival of the final decision until it became inoperative, and the evasion of royal orders was at this time severely felt by the ecclesiastics. Las Casas consequently represented these abuses to the council and procured a final cédula which entrusted the enforcement of the preceding ones to the audiencia of Mexico, authorizing that court to punish disobedience to previous decrees. [Sidenote: SUCCESS OF THE FRIARS.] In 1541 Fray Luis Cancer returned to Guatemala, and continued in Vera Paz the work of conversion inaugurated by Las Casas. From this time the pacification proper may be considered to have begun.[XX‑50]
