The priests of those days were, generally, the only scholars. They were learned in many things. Having to make their own convents and monasteries on uncultivated grounds that were granted to them by the Crown, it was necessary that they should be good farmers and good gardeners, or their lands would have been too poor to support them. For the decoration of the chapels where they prayed, and for the comfort of the refectories where they ate and drank, it was necessary that there should be good carpenters, good smiths, good painters, among them. For their greater safety in sickness and accident, living alone by themselves in solitary places, it was necessary that they should study the virtues of plants and herbs, and should know how to dress cuts, burns, scalds, and bruises, and how to set broken limbs. Accordingly, they taught themselves, and one another, a great variety of useful arts; and became skilful in agriculture, medicine, surgery, and handicraft. And when they wanted the aid of any little piece of machinery, which would be simple enough now, but was marvellous then, to impose a trick upon the poor peasants, they knew very well how to make it; and _did_ make it many a time and often, I have no doubt.
