The poet-heart of Columbcille could sing of his regret for the island of his birth; but he was not the man to let it interfere with his work for God in the island of his adoption. Iona consisted for the most part of barren and desert moor. Columba asked and obtained it as a gift from Conal, King of the Dalriadan Scots, and set his monks at once to cultivate the soil. The huts of the brethren were built in a circle round the church, with a guest-house and a simple refectory adjoining. The building was of wood and wattles, and the work proceeded rapidly. The hut of Columba was in the most elevated spot of the monastic enclosure, and here, during the short intervals between his missionary journeys, he spent his time in prayer, study, and the transcription of the Holy Scriptures. Iona had its writing school for the training of the younger monks, and became famous later for the excellence of its scribes. Adamnan in his Life of St. Columba mentions the scriptorium with its waxen tablets and the styles for writing, the inkhorns and the pens, with the brushes and the colours for illuminating the manuscripts. In all the labours of the day Columba took his part; no work was too humble for the holy abbot, and he exacted from others the same cheerful diligence as he himself practised. No one was allowed to be idle, there was work enough for all, and each was expected to take his share. When the manual labours were ended for the day, the monks betook themselves to prayer, reading, or writing, while the less expert could always employ themselves in works of charity for the common good. Even while the brethren were engaged in active labour, they strove to occupy their minds with thoughts of God, so that their work might be hallowed by prayer and bring its blessings on their mission. When the toils of the day were at an end they took their rest on their hard pallets of straw; but Columba slept on the bare ground with a stone for pillow, as had been his custom from his earliest years.
