 sources by observing whether the impulse received is towards good or evil, whether what is suggested is worthy of God, whether it tends to disturb our peace or leaves us tranquil and disposed to the service of God. Dreams have ordinarily a natural cause, but they are no indication of what the future will bring. We may not, then, guide our conduct by dreams; God has given us our reason and the Church to teach us what we should do; we must follow these anld not dreams if we would act aright. Constantly to guide ourselves by dreams would be mortally sinful, to allow them to influence us occasionally and in matters of little moment would not be more than a venial sin.

4. There is no harm in casting lots to decide a doubtful claim; the parties merely agree to stand by what turns up by chance. It is superstitious and sinful to cast lots in order to discover some secret, or with a view to shaping one's life according to the issue. Sometimes this method of deciding doubts has been adopted by holy men in consequence of an intimation received from God, or sometimes because no better way out of the difficulty appeared.

The use of the divining-rod under the belief that a stick of a special shape cut from a particular kind of tree or bush will point out hidden treasure, or mines, or springs of water, is superstitious and sinful. For it is certain that there is no natural force which acts in the arbitrary manner in which the divining-rod is said to act under the circumstances. It is not impossible but that particular individuals may be very sensitive to the presence of water or minerals even when hidden under the surface of the earth, and perhaps the frequent finding of springs by dowsers is partially to be explained in this way. Then by practice and experience a power of detecting the presence of underground water from the vegetation or other signs on the surface may be developed. There is also without doubt a great deal of fraud in such matters. Finally, the devil may sometimes intervene.

5. Modern spiritism is obviously the pythonism, necromancy, and other forms of divination which have been mentioned above. It is gravely sinful, therefore, to act as a medium or to consult one with a view to finding out something which is not known. Crystal-gazing, table-turning, the use of the planchette for occult purposes, is also divination and grievously sinful. It is not impossible that the movements of the table in table-turning and of the planchette are due to the unconscious action of the sitters. On this hypothesis it
