Mediumship has come to be a profession steadily pursued by quite a number of persons, who get their living by it.

There are various classes of “mediums,” the operations of each class being confined to a particular department of “spiritual” humbuggery.

Some call themselves “test mediums;” and, by insisting upon certain formulas, they succeed in astonishing, if they don’t convince most of them who visit them. It is by this class that the public is most likely to be deceived.

There is a person by the name of J. V. Mansfield, who has been called by spiritualists the “Great Spirit Postmaster,” his specialty being the answering of sealed letters addressed to spirits. The letters are returned—some of them at least—to the writers without appearing to have been opened, accompanied by answers purporting to be written through Mansfield by the spirits addressed. Such of these letters as are sealed with gum-arabic merely, can be steamed open, and the envelopes resealed and reglazed as they were before. If sealing-wax has been used, a sharp, thin blade will enable the medium to nicely cut off the seal by splitting the paper under it; and then, after a knowledge of the contents of the letter is arrived at, the seal can be replaced in its original position, and made fast with gum-arabic. Not more than one out of a hundred would be likely to observe that the seal had ever been tampered with. The investigator opens the envelope, when returned to him, at the end, preserving the sealed part intact, in order to show his friends that the letter was answered without being opened!

Another method of the medium is, to slit open the envelope at the end with a sharp knife, and afterward stick it together again with gum, rubbing the edge slightly as soon as the gum is dry. If the job is nicely done, a close observer would hardly perceive it.

Mr. Mansfield does not engage to answer all letters; those unanswered being too securely sealed for him to open without detection. To secure the services of the “Great Spirit-Postmaster,” a fee of five dollars must accompany your letter to the spirits; and the money is retained whether an answer is returned or not.

Rather high postage that!

Several years since, a gentleman living in Buffalo, N. Y., addressed some questions to one of his spirit-friends, and inclosed them, together with a single hair and a grain of sand, in an envelope, which he sealed so closely that no part of the contents could escape while being transmitted by mail. The questions were sent to Mr. Mansfield and answers requested through his “mediumship.” The envelope containing the questions was soon returned, with answers to the letter. The former did not appear to have been opened. Spreading a large sheet of blank paper on a table before him, the gentleman opened the envelope and placed its contents on the table. The hair and grain of sand were not there.

Time and again has Mansfield been convicted of imposture, yet he still prosecutes his nefarious business.

The “Spirit-Postmaster” fails to get answers to such questions as these:
