What is a spirit rescue?

Is it possible for spirits to rescue a person in a case of shipwreck, that is, to lift him from the sea to a place of safety?

It is quite possible. If in proper rapport with him, the spirits in attendance would be able to rescue him by some means or other—they might not be able to lift him from the waters, but they might be able to prepare a raft—or something else, and setting him on it, they might guide a vessel to pick him up. If the destruction of a vessel is foreseen by spirits interested in one of the passengers whose sandglass is not nearly run out, he will not be left to perish—they will say he must be saved and they will fall on many contrivances to accomplish the end. They will if the danger is foreseen in time try to influence him to remove from the vessel in which he intended to sail. On the other hand, though he were a medium, there are times when his spirit friends could do nothing for him. There are times when if we chose we could carry this medium away—and that without the slightest difficulty, but under other conditions, we could not lay a finger on him.
