"This knowledge in the head of a prison should show itself in his manner of dealing with prisoners. This task demands a high degree of pedagogic skill, and a force of character which is able, easily and quickly, to bend the will of others to his own. He should also possess the power of setting every branch of the administration to rights whenever anything happens to have gone wrong. He must have a quick eye for all that is being done; he must see everything; he must hear everything; nothing should escape him; and still he ought to leave independence and initiative to every officer in his own department. He should respect and bear with the individual characteristics of every officer, especially the superior officers, so that they may be able to perform their duties with pleasure. In this way all officers will be able to do their work in his spirit rather than according to his orders. In order to succeed in this, the head of a prison should consult with the other officials on all important matters; a daily conference is best for this purpose. He should hear and weigh their opinions even when the ultimate decision rests entirely in his hands. Above all he must understand how to keep peace among the officials, so that through their harmonious co-operation the objects of a prison may be more certainly attained. "A good prison chief," Herr Krohne continues, "is not matured or educated, but discovered. On this account, the selection of persons ought not to be narrowed down to any definite class or profession. Experience has shown that able prison governors have been drawn from all callings; from the law, from public offices, from the army, from medicine, from the Church, from trade, from agriculture, from merchants and manufacturers. From each of these occupations a man may bring knowledge and ability which makes him suitable for the position. His preparatory studies will teach him much, but he will learn most from actual practice, and he will never finish learning, however experienced he may become. But the root of the matter which can never be taught is a heart for the miserable; a determination in spite of failures and disappointments to despair of no man and nothing."[46] [46] _Lehrbuch der Gefaengnishunde von K.
